Description
The cross reference of related application
The application requires the right of priority of the U.S.Provisional Serial 61/731153 that on November 29th, 2012 submits to according to 35U.S.C. § 119, and its full content forms foundation of the present invention and is incorporated herein by reference.
Technical field
The present invention generally relate to for processing and finishing glass and more particularly processing and the thin glass web material of finishing in every way use (comprise and being incorporated in high-tech product) method and apparatus.
Background technology
Consider nearest development, glass can manufacture the form of thin glass web, and it has the thickness being no more than 0.05 to 0.200 millimeter, the width of 0.5 to 1.3 meter or wider and nearly 300 meters or larger length.Thin glass web material can be rolled on spool, and the little radius to 200 millimeters of external diameter.Thin glass web material has various purposes, comprises as the substrate for flat-panel monitor (such as, liquid-crystal display).Current techniques for handling thin glass web material uses for reference the volume to volume process from converting industry usually, and this process processes material when material moves in the horizontal direction.This method is consistent with the method for the various materials for processing in volume to volume process, and these materials comprise paper, plastics and metal, and there is special supply and be used for the industrial sector widely of the equipment processing these materials.In general, these systems have level design, wherein, when material be just formed, transform or add coating, laminates, circuit form value and be just transferred in some cases by a series of process environment, vacuum, heat, sputtering, moisture eliminator etc. time, material by a series of transmission technology (being roller in many cases) in horizontal alignment upper feeding.Many in these process steps are suitable for horizontal web transmitting procedure in essence, and therefore most of converting apparatus design all adopts horizontal arrangement also just not at all surprising.
Handle and process thin glass web material after the fabrication and propose many specific questions, particularly cut at thin glass web material, check, test defect and laminated or carry out other manufacturing step time need to avoid being in direct contact with it when thin glass web material moves in the horizontal direction.Directly to be contacted with thin glass web material by treatment facility and easily may increase scratch, scratch or other defect, these defects not only affect the visual appearance of glass, and introduce the structure that may weaken glass and cause the inefficacy of crackle form and the defect of catastrophic failure of wherein glass pulverizing.In order to process thin glass web material in being designed to avoid the horizontal volume to volume contacted with thin glass web material direct physical to operate, depend on air bearing technology to a great extent, this technology is merged in transmitting device, reverser, turns to and plane treatment facility.These devices allow thin glass web to bridge on air cushion along horizontal production line, and this horizontal production line can reach 10 meters or longer, and at least wide 1 meter to 1.5 meters.These systems need the air bearing device of nearly 10 to 15 high complexity for different object usually.
Summary of the invention
As mentioned above, when thin glass web material moves in the horizontal direction during finishing, in order to avoid touching and the noncontact contributing to thin glass web material move, complicated, exquisite and extremely expensive air bearing apparatus array formation air cushion, bridges thereon when moving in the horizontal direction between unwind module and winding module for thin glass web material.In some configurations, air bearing apparatus array is series of parallel guide rail, and it utilizes the outlet pathway release air provided by the space between guide rail to form air cushion.These arrays usually cover most of region that thin glass web bridges.Except reversion, test and tensioning, these arrays also keep air rod.
As mentioned above, if thin glass web material breaks during finishing, when it moves along horizontal production line, many problems are produced.When thin glass web material breaks, it may form many small-particles, and these small-particles can pollute machine, particularly many air bearing devices.The small-particle generated by breaking in thin glass web have finishing can before adhere to the trend of machine, thus produce significant cleaning problems.When thin glass web material breaks during finishing, the small-particle of the glass formed also is blown everywhere by the air from air bearing device, and this may make situation more serious, and increases clean time and expense.
Other prominent question is, all these processes all must be carried out in clean room environment, and this needs to have HEPA filtered air, so that process area is remained on rank 10, in 000 target.When thin glass web material breaks, cleaning course superposes with the following fact: it may need to reach the standard of rebuilding clean room environment.
Again it is difficult for connecting after the rupture or connecting thin glass web material by system horizontal simply when finishing starts, and is partly due to needs not Contact Thin glass web material.Thin glass web material needs to connect above the below of winding both modules and a series of air rod and reverser by path selected by system, this is one and has multiple functional process challenged with human engineering, reason is: air rod is sprawled above the floor space of significant quantity, and wherein the part of system is difficult to touch from the side.When thin glass web material moves by horizontal process, this problem superposes with distance very little between thin glass web material and air bearing device.
Winding tension management is the controling parameters for preventing the omnidirectional crack be associated with laser cutting and other finishing and test process from spread, and needs cutting the Winding Tension Controlling of process with other correction step upstream and downstream.Horizontal process usually use stretched wire, floating roll or vacuum chamber tensioning technology and complexity control algolithm to meet the tensioning requirement of given process.Winding tension is measured traditionally in web transmission industry in units of pound/line inch or PLI.Thin glass web move by finishing and when its unwinding time, tension force in thin glass web is substantially in the scope of 0.05 to 0.75 pound/line inch (PLI) (0.06 to 0.9Kg/cm), this value is lower than PLI normally used in the converting industry for plastics, cardboard and other material, and it is usually in 1 to 5PLI scope.Extend to avoid Contact Thin glass web material under tension force low like this to challenge to Controlling System in the air bearing portion that supporting is provided in the horizontal direction, and to need in the manufacture and alignment procedure of air bearing device and relative to the very high precision of coiler and other process device.This requirement increases the design of process device and the significant cost of operation and complicacy.In addition, because web needs supporting in its whole path length, it is close to air bearing consistently, which increases it and contact may can cause the possibility of the something of scratch or flaw (this scratch or flaw can weaken the mechanical integrity of glass) in some way.
Existing system horizontal also has binding character on the width that thin glass web material energy is cropped.This is because air rod is positioned to have space between which by needs, and this space allows air effusion, to keep appropriate air pressure.When thin glass material moves in the horizontal direction, the edge of thin glass web material must reside in before and after cut air pressure is provided guide rail above and above one of gap not between air rod.Therefore, the alternating pattern of air rod and open space limits the width that thin glass web material can be cut.
An embodiment of the present disclosure relates to a kind of method for processing thin glass web material, and it has following steps: by thin glass web material from source along essentially towards under vertical direction guide; To along essentially towards under the thin glass web material of vertical direction movement perform finishing function; Control when there is no physical contact essentially towards under vertical direction on the horizontal stability of thin glass web material of movement; Control when there is no physical contact essentially towards under vertical direction on the tension force of thin glass web material of movement; And thin glass web material is wound at least one volume, at least one volume described can be positioned to substantially in the below in the source of the thin glass web material moved down.In the modification of this embodiment, source step is: by thin glass web material from spool unwinding; In ending place of manufacturing processed, thin glass web material edge is in downward direction guided; Or thin glass web material is upwards walked around above air rod.
Additional embodiment of the present disclosure relates to a kind of equipment for processing thin glass web material, and it comprises: the source of thin glass web material; Winding reel, it is positioned at below the source of thin glass web material on substantially vertical direction; Contactless stabilizer, its contiguous path extending to the thin glass web material of described winding reel from described source; At least one calibration devices, its contiguous path extending into the thin glass web material of described winding reel from source; Contactless tenslator, it is positioned at the interaction position with the path of thin glass web material; And wherein, thin glass web material path essentially towards under vertical direction on extend to winding reel from source.

Embodiment
Provide the example with reference to accompanying drawing more detailed description embodiments of the invention.The example provided and embodiment show concept of the present invention, but should not be construed as and limit the invention to embodiment provided herein.But it is evident that for benefiting from those of ordinary skill in the art of the present disclosure, the present invention can put into practice in other embodiment not departing from detail disclosed herein.In addition, the description of device, method and the material known may be omitted, in order to avoid make description of the invention indigestion.In the case of any possible, all use identical Reference numeral to represent same or similar parts in the accompanying drawings.
First embodiment
Fig. 1 is the perspective illustration of some in the major parts of embodiments of the invention.Volume 101 is spools of thin glass web material, such as, wide 1 to 1.3 meter, thick 0.01mm to 0.2mm (such as, 0.01,0.02,0.03,0.04,0.05,0.06,0.07,0.08,0.09,0.10,0.11,0.12,0.13,0.14,0.15,0.16,0.17,0.18,0.19 or 0.20mm), it is wound into diameter and can be as small as the volume of 200mm and reaching in the band of 300 meters or more or ribbon (term " band " or " ribbon " can exchange use in this article).When the demand to thin glass web material of generation, may need to carry out extra processing to it, such as, be cut into concrete width, with by it for the preparation of manufacturing processed, this manufacturing processed is incorporated to another product, such as, the substrate of flat-panel monitor.By its unwinding on downward vertical direction for processing the technology of the volume 101 of thin glass web material 103, it is processed, such as, thin glass web material lengthwise is divided into two independent band 107A and 107B by cutting unit 105, then by they rewinding rolling 109 and 111 respectively.
The developed width of thin glass web material can change.In the example illustrated in figure 1, when web material departs from volume 101, its width is in the scope of 1 meter to 1.3 meters, and it is cut into two independent bands, and the width of these two bands adds up the total width of initial cut 103.According to the position that cutting unit 105 is located, thin glass web can in any position lengthwise segmentation across its width.In addition, its can be cut into several less bands and rewinding become required for many volumes.Cutting unit 105 is typical laser cutting devices, and its generation is designed to the laser beam 104 cutting thin glass web material.But, other suitable cutting unit can be used.Because the system described in Fig. 1 there is no need for the air bearing device of supporting and protection; laser cutter 105 easily can be positioned at any some place of the width along thin glass web material 101, therefore thin glass web material 101 can be cut to any required width.Cutting step also can be included in the narrow pruning otch on one or two edge of the band of thin glass web material.One of importance of method and apparatus discussed in this article will be that it works when not Contact Thin glass web material and is therefore contactless equipment and method.
As noted, when thin glass web material moves by finishing, be the important factor needing process and keep to the appropriate tension force management of thin glass web material.Thin glass web material is moved, one of gravity fundamental component becoming tension control by the vertical direction, and the process in fact simplifying tension force management and control.When thin glass web material moves on downward vertical direction, its quality automatically provides tension control.Therefore tension force on thin glass web material become the thin height of glass web material and the factor of quality of movement.
By keeping suitable height and the quality of glass web, the suitable tension force on thin glass web material can be remained within the scope of acceptable PLI.In addition, when thin glass web material along with it moves and cropped (because this process is vertical in a downward direction, and comprise the contactless guiding not hindering the advance of web) time, gravity can be used to send suitable tension force cutting on band of thin glass web material, no matter and relative to initial overall with how the width of the band of cutting, therefore allow to use minimum additional tension technology and control algolithm.This provide the huge advance comparing system horizontal, as mentioned above, system horizontal needs extremely complicated clamping system, to keep suitable tension force and to provide by cutting the tension variation caused with other correction step.In addition, this system nature is contactless system.
Stretched wire 113a and 113b of cutting band 107a and 107b is all to provide needed for additional tension control.They are calculated to be wrapped on its corresponding volume 109 and 111 in ending place of process along with them and to produce suitable tension force on each band of thin glass web material 107a and 107b.Thin glass web material being wound into one of requirement on volume is: when it is wrapped on volume, it is by tensioning rightly.Tension force excessive in winding process can by exceedingly compressing it and damaging thin glass web material and cause scroll expansion.When the flexible hightension excessively occurring in the material rolled causes the center of spool penetrate and effectively break volume.In addition, if apply too small tension force, the volume of thin glass web material by pine, and easily stretches when standing rapid horizontal.
The stretched wire that each band is formed when it hangs low is physics and geometrical curve form, its be similar to chain or cable suspension between two supporting members time the curve that formed.In this case, when corresponding band 107a and 107b by rewinding on spool 109 and 111 time tension force thereon depend on the vertical height how far dangling and start at thin glass web material the point thin glass web material that in the vertical direction moves down from source (in this case from volume 101) below each in its corresponding spool of stretched wire 113a and 113b of each band 107a and 107b.As mentioned above, thin glass web material usually sometimes lower in the scope of 0.05 to 0.75PLI (0.06 to 0.9Kg/cm) in the tension force of PLI, to produce suitable final tension force when winding process completes again on the volume of thin glass web material.Another advantage of processing thin glass web material on being vertically oriented is: lower tensile requirements makes more easily to handle the necessary tension force that thin glass web material also realizes requiring on thin glass web material.One of importance of stretched wire is, it provides contactless tension control method and equipment.
As depicted in Figure 1, cut the process of thin glass web material and other process can when without any need for air bearing device or as hereafter show strategically place so on a small quantity device carry out.In addition, the space that vertical process need is much smaller, which reduces the cost of clean room's environment that must provide during the process of thin glass web material.This dramatically reduces when in thin glass web material break occur time cleaning cost and the time.For vertical process, clean real space is needed to need clean space much smaller than horizontal process.In addition, as shown in whole embodiment, the equipment occupying the floor area immediately below vertically-oriented thin glass ribbon thing seldom or not exists, thus further simplify cleaning course and decrease the pollution for the treatment of facility.Such as, rewinding spool 109,111 and equipment associated with it, from outwards movement immediately below vertically-oriented thin glass ribbon thing, pollute to reduce it in the Surface Rupture Events causing thin glass ribbon thing to fall.In addition, although not shown, but arrange above in the process floor of rewinding spool and may there is hole, to allow glass ribbon thing through wherein falling into independent space, for the pollutent collecting fragment gentle year particle, these pollutents otherwise rewinding spool and other ribbon treatment facility can be polluted.
Another advantage of vertical process is the significantly simplification of threading procedure, and this process starts to cut on the spool of thin glass web material or connects required for spool after other finishing or the disconnection in thin glass web material again.As seen in Figure 1, thin glass web material can easily be launched from spool 101 and be moved along downward vertical direction by gravity, so that then easily to connect on lower rewinding spool 109 in very simple process.People only need to catch its leading edge when thin glass web material is moved downward to the level of rewinding spool 109 and 111, and after thin glass web material is cropped, it are connected to rewinding spool in an appropriate manner.
In a preferred embodiment; the guide portion of plastics or other suitable fabric can be attached to the available end of the thin glass web material on spool; to be conducive to threading procedure, and be in contact with it for thin glass web material provides to protect and limit during threading procedure.Fig. 2 is the schematic diagram of end when it departs from spool (not shown) of thin glass web material 131.The end of the guide portion 133 be made up of plastics or other suitable material or fabric is joined to the edge of thin glass web material 131 in cutting and splice plate 135 by band (not shown) along line 137.In ending place of process, when thin glass web material is wound around completely again, the portion of trailing of plastics or other suitable material is added to serve as guide portion in next measure taked at the volume of thin glass web material.Splicing guide portion or the process of trailing portion all can be in while it is vertically oriented and carry out by thin glass web material after unwind process starts.Can use and change splicing manually or automatically.In manual processes, people can easily stand near cutting or splice plate 135, and cutting or splice plate 135 are positioned to the contiguous thin glass web material 131 hung.
Second embodiment
Fig. 3 provides the schematic side elevation of another embodiment of the main function components being attached to backboard 201.The backboard 201 that all parts described in Fig. 3 are all functionally attached to from it stretches out.Spool 203 is rotatably attached to backboard 201 by axle 204; and reel one section of thin glass web material around it; one or more bands of thin glass web material and protecting materials 205 (such as; medical-grade foam) interweave, the band 205 of protecting materials can have the width being equal to or less than thin glass web material.Axle 204 extends in backboard 201, and has the prime mover (not shown) that gear is connected to it, to give spool 203 suitable rotation in suitable sense of rotation where necessary.The thin glass web material of combination and the band 205 of protecting materials are from roller 203 unwinding and walk around above roller 207, and thin glass web material 103 is separated with one or more bands 211 of protecting materials.The band of protecting materials then guides to spool 213 downwards, and here, it is by rewinding.Thin glass web material 103 moves from top to bottom along air bearing supporting member 215, and here, it is cut into two independent bands by laser cutter 217, that is, band 209b and 209a.Air bearing supporting member 215 forms air cushion, bridges above for thin glass web material, makes it directly can not contact with the surface of air bearing supporting member 215.Practical structures on the face of air bearing supporting member will be discussed below.
The band 209a of thin glass web material then walks around downwards below floating roll 221 after cropped and transmits, and is then with 227 to be combined with another of the protecting materials from spool 229 unwinding.The band thereunder with the thin glass web material 209a of the band 227 of protecting materials then to be walked around above roller 225 and is wound on spool 231.Equally, thin glass web material 209b walks around below floating roll 223, then with is just combined from the protecting materials band 242 of spool 243 unwinding.Then, thin glass web material and walk around roller 241 with the band of the combination of the band of the protecting materials of its intertexture and be wound on spool 256.Spool or roller 207,213,225,229,231,241,243 and 246 all utilize suitable gear to be connected and are rotatably attached to plate 201 with prime mover in the mode identical with spool 203.
Floating roll 221 and 223 provide respectively walk around in them each below the contactless tension control of band 209a and 209b.Alternatively; in order to increase stability, control and for the protection of high frequency or low-frequency vibration (when thin glass web material moves by this finishing; this high frequency or low-frequency vibration can cause in the band of thin glass web material or ribbon); contactless stable air rod 251 is positioned in a distance adjacent tapes 209a; in this distance, the vibration in band 209a can be controlled.Equally, contactless stable air rod 252 is positioned in a distance adjacent tapes 209b, in this distance, can control and prevent the excessive low frequency in the band 209b of thin glass web material or high-frequency vibration, thus providing stability for thin glass web material 209b.
In a preferred embodiment, air rod stabilizer 251 and 252 exerts empty profit gas rod stabilizer for shellfish, and it is the thin glass web material of physical contact not, thus provides contactless stable and control to the movement of thin glass web material.Fig. 4 provides the view that shellfish exerts a part for the operating surface 257 of empty profit gas rod, that is, when thin glass web material in the vertical direction moves, towards and be positioned to the part of the band of contiguous thin glass web material.The face 257 that shellfish exerts empty profit gas rod has positive port 258, and air is blown out by this port, to produce positive air pressure or repulsive force on the band of the thin glass web material of process.When thin glass web material exerts empty profit gas rod face 257 through shellfish, vacuum ports 259 produces negative air pressure or suction force on thin glass web material.Then, thin glass web material is controlled in its position when shellfish exerts the face 257 of empty profit gas rod by the selectivity change of exerting the flow of the negative, positive airflow that the face of empty profit gas rod is formed shellfish and is changed.By this way, the distance of the band of the thin glass web material of process can be accurately controlled.In addition, any direct contact between the band and the face of Bei Nu empty profit gas rod of the thin glass web material of process is helped avoid.It is here unnecessary that shellfish exerts discussing in detail of the structure of empty profit gas rod; Can say completely, such air rod has the suitable internal structure of conduit and air flow generator, usually to provide and control to leave positive air port 258 and enter following of the air of negative air port 259.Air bearing supporting member 215 also can have Bei Nuli configuration.

When thin glass web material arrives floating roll 347, it is gone up in upward direction and alters course towards alignment roller 350.In addition, before thin glass web material is walked around above roller 350, the band 352 of protecting materials at thin glass web material weaves beneath, thus provides protection for thin glass web.In conjunction with thin glass web material and protecting materials then by rewinding on spool 355.Floating roll 347, to work with the identical mode described in Fig. 5, keeps tension force to utilize suitable counterweight; But, as an alternative, mechanism that unshowned gear connects can be used as tension control mechanism.In addition, tension control arm 357 can be used to control the operation to the rewinding on spool 355, and it operates in the mode identical with mentioned strain control arm 319.When protecting materials is wound on around roller 350 below thin glass web material 103, spool 356 helps the band of protecting materials to guide to roller 350 from spool 354, and controls excessive vibration.In addition, roller 307,327 and spool 309 are connected to the backboard 315 having with them and be rotatably connected, and have suitable rotary motive force (not shown).All have, to the similar spool be rotatably connected of backboard 349 and roller 350,354 and 356, there is suitable rotary motive force.In addition, as mentioned above, the tension force of this embodiment and the naked surface of horizontal stable method and apparatus also for utilizing the finishing of contactless method and apparatus to provide thin glass web material.
Testing apparatus and method
In order to test the integrity of thin glass web material and guarantee its quality, in the enterprising row filter test of thin glass web material.Screening is that this air bearing cylinder provides contactless method and apparatus by alternately causing thin glass web material being placed on tensioning and the process compressing orientation by two of thin glass web material by a pair moveable air bearing cylinder along path clockwise with in both counter clockwise directions.When glass-coated is around air bearing cylinder, the outside of glass is placed in tensioning state, and the inside of glass is placed in compressed state.The degree of tensioning and compression be the value of radius, the thickness of glass and glass through by bending with the function of the time length of movement.Utilize this technology, thin glass web material can for edge and surface imperfection tested, to guarantee that glass has integrity and has been manufactured into suitable specification.In addition, this test is quality test, and its thin glass web material guaranteeing to give client does not have possibility and causes its defect lost efficacy in its manufacturing processed.
Fig. 9 and 10 provides the schematic diagram of an embodiment of screening installation.Fig. 9 shows the screening installation being in non-deployed position before testing begins, and Figure 10 shows the screening installation being in abundant deployment mode carrying out filler test.The equipment 341 described in the figure 7 will be deployed as referring to the particular screen device described in Fig. 7, Fig. 9 and 10.
Again referring to Fig. 9, be provided with the sheet material of thin glass web material 103 between two relative air bearing cylinders 401 and 403, it is just along in downward direction moving.Air bearing cylinder 401 is made up of pneumatic actuator 411, axle 413 and round end 415.Axle 413 is placed on roller 419, and roller 419 is placed in again on conveying 417.Then, air bearing cylinder 403 is made up of pneumatic actuator 421, the axle 423 with round end 425 equally.Axle 423 is placed on roller 429, and roller 429 is placed in again on conveying 427.In addition, air rod 405 be positioned at top and thin glass web material the opposite side relative to air bearing cylinder 401 on, and the second air rod 407 be positioned at below and on the opposite side relative to air bearing cylinder 403 of thin glass web material 103.
The round end 415 of air bearing cylinder 401 and the round end 425 of air bearing cylinder 403 construct in the mode similar or identical with 407 with air rod 405, and are similar to institute in Fig. 3 and 7 and describe such.These elements can be the Bei Nulishi air rods that positive port and negative terminal mouth are arranged to the matrix described in Fig. 4, or the standard type with alternate row separately as depicted in figure 6.Naturally, the row and column of positive flow port and negative flow port or matrix are by the front 431 of round end 415 and on the front 433 of round end 425.Airflow in the positive hole of round end 415 and 425 and negative hole provides by axle 413 and 423 from the internal path by actuator 411 and 421.Figure 11 provides the vertical view of the embodiment describing air bearing cylinder in Fig. 9 and 10.As appreciable in these figures, round end 415 has the width of prolongation, and this width is by equally wide with the band of the thin glass web material carrying out filler test above.Such as, the overall with across the thin glass web material 103 moving through air bearing cylinder is downward extended 1 meter or 1.5 meters by this width.Round end 425 will have the same widths extended across the whole width of thin glass web material.
Referring to Figure 10, both air bearing cylinders 401 and 403 are in complete deployed position, each wherein in their corresponding round ends 415 and 425 forms suitable curvature in thin glass web material 103, to carry out filler test, and not physical contact thin glass web material and therefore carry out filler test in contactless mode.Round end 415 extends into the path of thin glass web material by actuator 411, and actuator 411 makes axle 413 extend out to suitable length.Equally, the actuator 421 of air bearing cylinder 403 makes axle 423 extend out to suitable distance, thus is joined to by round end 425 in the path of thin glass web material 103, with the radius-of-curvature needed for the formation of this some place.Because round end 415 and round end 425 all have the suitable air bearing structure as mentioned above on its corresponding face 431 and 433, when thin glass web material going down is through round end, in fact it be suspended on the air cushion that formed by corresponding round end.Because test round end flatly activates on the high quality linear guides of standard, the unique power they be placed in needed for test pattern is the power needed for dislocation web path.This method being used in the clock like precision of the total tension force measured in web path becomes possibility.In addition, it provide this may: according to the amount of the web path of dislocation while being engaged in this system, screening system also can serve as the alternative role of contactless tenslator, to adapt to the brief situation of tension variation.
Utilize this device, can test thin glass web material for edge and surface imperfection, both not only allows test mass and integrity, and contributes to setting up the understanding to material itself.
Equally, as previously mentioned, as described in accompanying drawing herein, glass is delivered to screening plant to be vertically oriented and provides the cost of the design of influential system and multiple advantages of terseness.The easier of test macro that it not only can realize discussing before this connects, and reduce following possibility: owing to contacting with the accidental mechanical of glass during test process, test process will bring infringement to glass, cause the glass being scratched, weakening with flaw or mechanical integrity.Because thin glass web material is just provided to test set to be vertically oriented, as system horizontal before this, no longer need the air bearing rod of plane.This allows it to provide the upper and lower testing radius replaced independent of each other, and do not produce wherein web path can from the angle on surface or the situation of direction ingress of air rod may damaging web.
Finally, as pointed out before this, no matter total band on vertical direction or ribbon path, when the glass breakage caused by test process itself, actual cleaning area will be limited to the floor area immediately below web path, make the amount of the pollution to inspection machine minimize thus.
