MESNE ASSIGNMENTS, TO POPE APPLIANCE CORPORATION, OF PORTLAND, MAINE, A CORPORATION OF MAINE MECHANISM FOR WINDING PAPERINTO ROLLS Application filed August 30, 1929, Serial No. 389,404, and in Canada June 28, 1929.

This invention relates to mechanism for winding paper webs into rolls, and has reference more particularly to such mechanisms as are used to handle the paper web delivered continuously from paper making machines. Mechanisms for this purpose are now being used, one for instance being known as the English type reel, and comprise a drum known as under or driving drum with Which two winding reels are mounted to co-operate, the web being wound on the reels alternately; when one reel is filled, the Web'is severed and the new length fed onto the empty reel, the filled reel being removed and anv empty reel substituted in its place.

Our invention consists of a mechanism of this general type, but of improved form in which. the continuous web to be rolled is wound alternately on two winding reels cooperating with and driven by the under drum, the web being severed when one of the reels is filled and the new length of web, following severance, automatically directed to and wound around the other reel, and the web again severed when the latter reel is filled, the next new length being automatically directed to an empty reel which has in the meantime been substituted for the first filled reel; the operation of severing the web is repeated, so that the web is fed automatically to and wound around the reels alternat'ely and without interruption.

Our improved mechanism results in and has for prime objects, the almost complete elimination of waste of paper web or stock arising now under known mechanisms, saving in labor and machine production time, substitution of unskilled for skilled labor and a reduction of dangers and hazards incident to the operation of known machines.

in the specification to follow, our improved mechanism is described in detail, and the novel features thereof pointed out in the appended claims.

In the drawings: Figure 1 is a side elevation of a winding mechanism of the type known as the English reel (with parts removed), improved so as to constitute our invention;

Figure 2 is a fragmentary top plan view showing portion of one of the air blast devices.

Like numerals of reference indicate corresponding parts in the various figures.

Referring by numerals to the drawings,

and more particularly to Figure 1, our mechanlsm comprises essentially an under drum 10, two winding reels 11 and 12 on which severed portions of the continuous web 13 are wound alternately, and for which'similar winding reels are substituted when these are completely filled, a device 14 for initiat-.

ing the severance of the web, a fluid blast device 15 to act on the new lengths of the severed web and adjustable to direct said lengths alternately to the two reels, and asecond fluid blast device 16 associated with the under drum and operable to direct the new length of web carried by the drum onto the reel 12.

The rotary drum 10 is journalled in suitable bearings 17 in a frame 18 and is driven from any source of power (not shown), usually an electric motor connected to the. drum shaft with suitable reduction gears provided therebetween.

The reels 11 and 12 have end journals 11a and 12a respectively, turning in slotted ends 19 in the reel carrying anns 11b and 12b respectively. The arms 12?) are journalled at their lower ends to rock on studs 120 on the ends of the horizontal transverse member 20 fixed in the frame 18, so that the winding reel supported in the upper ends of said arms can move to and from the under drum,

thereby permitting the empty winding reel to contact with the drum at the beginning of the winding of the web thereon, as shown in Figure 1, and permitting said winding reel to gradually move away from the drum as the diameter of the roll of paper increases as the winding operation progresses.

The arms 116 are similarly journalled at their lower ends on studs 110 on the ends of the rear horizontal transverse supporting member 20a extending arallel to the supporting member 20 and Xed in the frame 18, whereby the winding reel 11 supported in the upper ends of sai arms, is permitted to swing to and from the drum for the same purpose as the corresponding action of the reel 12.

The paper web 13 coming continuously from the last pass of a calender stack of a paper making machine, (not shown) passes eneath and around a segmental guiding surface 21 fixed to the transverse supporting member 20a between the two arms 11b, and from this guiding surface the web passes into thebite of thewinding reel 11 and the drum 10. The web is first wound on the winding reel -11, and when this reel becomes filled and the web is severed so as to separate the wound web from the unwound web, thenew lengthof' the latter isthen directed to the" empty winding reel 12 to be wound thereon,

and-when this reel becomes filled, the web is again severed, and the succeeding new'length' .is directed to an empty winding reel which was in'the meantime substituted forthe filled'f The severance of the web is initiated by the device '14 before alluded to, which as shown in Figure I is located to act onthe web at a p0int-ahead of the bite of the reel 11' and drum 10,and preferably just after the web assesaround the guiding'surface 21. As est shown in Figures 2 and 3, this device may comprise a'horizonta'l blade 22 which is pivoted atone end on a vertical axis as at 23,

to a bracket 24 fixed to a strap 25 clamped to the supporting member 20a, the free end of the blade being pointed or sharpened so that when engaged with the traveling web, the latter will be broken or cut. By the mounting of the blade in this manner, it may be swung from an inactive position free of the traveling web, to an active position in the path of the web to engage the same. The .lade is thus actuated by means of an operating rod 26 mounted to slide endwise in guides 27 fixed at intervals to the supporting member 20o which rod extends at its outer end to the front of the machine frame, where it is provided with a handle 26a for operating it. At its inner end the rod is provided with a pin 27c engaging in a longitudinal slot 28 in the blade, and by pushing the rod rearwardiy, the blade will be swung rearwardly and engage with the traveling web, and then by the forward movement of the rod, the blade wid be disengaged from the web.

The engagement of the blade with the travcling web and the continued movement of the blade to engaging and again disengaging from the bite of these members, it is acted on by the fluid blast device 15, which by its adjustments will operate either to hold the lip against the winding reel or against the drum, according as to whether the new length of web is to be directed to one or the other of the two winding reels. In either case, the lip being held against the members or folded back by the action of the blast, the continued movement of the web due to its winding action, will cause the incision made by the blade to extend clear across the web and thereby completely sever the same. lip may be preferably formed as just menthe rod 26 be limited in one directionand To insure that a this is accomplished by suitably spacing the clamp 25 from the pin 23 so that the knife rearwardmost positiomshown as 22A in Figure3'." v

T hefiuid blast device 15 is located at the upper side ofthe under drum and between the two winding reels, as best shownin Figis not disengaged from the web while in its are 1 and it may consist of a horizontal sup 32 supported in hearings in the upper ends of two standards 33 rising above the bearings of the under drum, the said pipe being supplied with fluid under pressure, preferably air, from any suitable source, andvbeing provided about midway of its length with a number of air discharging nozzles 34 directed to the right as viewed in Figure 1 whereby by the rocking of the pipe 32, the air blasts issuing from the nozzles may be caused to impinge either on the winding reel 11 or upon the under drum 10.

The blast pipe 32 is rocked to thus adjust the blast nozzles, by means of an adjusting lever 34A fixed to the pipe 32 at the front of the machine and provided with a locking dog 35 adapted to engage in notches 36 and 37 in a segm nt plate 39 fixed to the forward standard 33. When the locking dog is engaged in the notch 36 dotted position of lever in F igure 1) the blast nozzles will be held so as to impinge their blasts against the drum; and when the locking dog is engaged in the upper pl pipe 32 mounted to rock in a larger pipe notch 37, (lever shown in full lines) the blast of the winding reel 11 and under drum, and follows with the web as the latter is wound on the winding reel, the blasts in actin on the winding reel will detach the lip there rom and in rebounding will throw the lip down on the under drum, and holding the lip against the under drum, the rotation of the latter in co-operation with the rotation of the winding reel, will sever the wound portion of the web from the unwound portion, and the latter will be carried around by the under drum towards the winding reel 12 to be wound thereon. When now the winding reel 12 becomes filled with the new length of web, and it is desired to sever the web and direct the following new length to the winding reel 11, the nozzles are adjusted so as to direct the blasts against the under drum, with the result that the newly formed lip on the web as it is carried around by the under drum and reaches the blast impinging thereon, will he lifted from the drum and the rebounding blast will carry it towards and press it against the newempty winding reel 11, substituted for the former filled reel, thereby severing the web as before and causing it to wind upon the new reel 11.

It is seen therefore that by the successive operations of the blade 22, and the adjustments of the blast nozzles, the new lengths of web may be caused to pass alternately to the winding reels.

It will be understood that in these successive operations, the blade is moved rearwardly and forwardly, and the blast nozzles are set in their different positions only long enough to effect the complete severance of the web, and the feed of the new lengths to the respective reels, whereupon the supply of the blast fiuid is out off.

When the air blasts are directed against the filled winding reel 11 in order to throw the detached lip on the web down on the under drum 10, the new length of web after the severance of the same, will be carried around the drum 10 past the empty reel 12, and will continue on down with the drum, and in order to detach the end of this new length from the drum and direct it to the empty winding reel 12, a doctor knife 38 is provided which bears constantly against the surface of the drum and will act to lift the end of the new length of web therefrom, and this new length is blown upwardly onto the vempty winding reel 12 by the blast device 16 before alluded to. This blast device 16 may consist of supply pipes 37 provided about midway of its length with blast nozzles 38A directed upwardly and tangentially to the surface of the drum and towards the winding reel 12 and end nozzles 38B positioned to impinge their blasts under the ends of the web. The pipe 37 is supplied with pressure fluid, preferably air, from a suitable source, and the blast is turned on only momentarily; and when the end of the new length is directed onto the winding reel 12 by the blast, the latter is turned off.

It will be understood that when the winding reels become filled, they will be removed from their supporting arms 11?) and 1% respectively, and empty and similarly winding reels will be substituted, so that there will always be an empty winding reel engaged with the drum and ready to receive the new length of web when the latter is severed.

From the foregoing description, it will be seen that the operations of winding the continuous web onto the two winding reels will take place continuously without interrupting the travel of the web, the attendant, as the winding reels become alternately filled with the web, operating the blade 22 and the fluid blasts l5 and 16 at intervals as the two winding reels are alternately filled. As a result there will be no interruption in the action of the mechanism, which will operate with eficiency and dispatch in the winding of the continuous web and without loss of material or time. 1
