The updraft device 10 consists essentially of a rotatably mounted revolver 16 on which mandrels 12a . 12b are stored. The revolver in turn has a shaft 162 with egg a rotary drive (motor) 164 on, being the shaft of a storage 166 is worn, in particular two rolling bearings. The axes 122 of the mandrel 12a and the mandrel 12b be through the yoke 160 worn by the revolver, in the schematic representation by the carrier 168 which at the yoke 160 are fixed and each one storage 126 for a wave 122 a mandrel 12a . 12b support. As in the lower part of 1b can be implied, between a carrier 168 and a storage 126 a sleigh 128 be arranged with a drive, whereby an axial displaceability of a shaft 122 with a mandrel 12a given is. The drive at 128 is indicated above the double arrow by a rectangle. It may be a lifting cylinder or, for example, also a linear drive. For every mandrel 12a and 12b is a displacement device 128 required to allow the change process according to the invention. As rotary actuators 124 for the spool pins or their shafts 12a . 12b respectively. 122 are preferably used electric motors, in particular asynchronous motors. For the contact pressure of the supplied thread 30 on the circumference of the thread winding on a mandrel 12a . 12b or on a spool 32a or a sleeve 32b serves a friction roller 14 , which preferably on a swivel arm 120 is stored. The center of rotation of this swivel arm 140 is located in the center of a wave 142 , to the rotational movement of a rotary drive 144a , for example. a stepper motor, can be provided. On the other hand, it is also possible on the swivel arm 140 according to 1a a rotary actuator 144b to steer, in particular a lifting cylinder, which can be controlled in particular hydraulically or pneumatically. To limit the range of motion of the swivel arm 140 serves a stop 148 according to 1a , The wave 14a the rubbing roller 14 is in the illustrated schematically cranked arm 140 stored. Alternatively, the friction roller could also be accommodated on a vertically movable carriage. In this case, instead of a rotary drive would have to a shaft 142 a vertically movable lifting drive be present. For storage of the shaft 142 is a storage 146 , preferably two rolling bearings, provided.

The rubbing roller 14 , also called speedometer, may have a speed measuring device, and is powered by a motor 144a be driven, the rotational speeds of the engine 144a in a certain ratio to the rotational speed of the rotary actuators 124 controlled or regulated.

As essential components of the updraft device 10 is still a traversing device 18 with a drive 182 to call, shown schematically in 2a and 2 B , It can be like in 2 B indicated to be a provided with a cross groove roller, which by the drive 182 is set in rotation. The over a thread eyelet 34 supplied thread 30 is by guiding in the groove of the traversing device 18 in the axial direction of a coil mandrel 12a or 12b emotional. Alternatively, for example, a pointer, in 2a With 18 designated to be the thread transverse to the plane of 2a in the longitudinal direction of a sleeve 32b to move on which the thread 30 is to be wound up.

While in 1a only one single coil each 32a and a sleeve 32b are shown in 1b two coils 32a or 2 sleeves 32b next to each other on a mandrel 12a and 12b shown. Usually located on a mandrel 12a respectively. 12b a winding device, as used in practice, a larger number of coils 32a or sleeves 32b next to each other, so that several parallel on the winding device tapered threads 30 can be wound up. For every single thread is a thread eyelet 34 according to 2 B and a guide score 194 in a displacement device 19 in the longitudinal direction of the coils 32a to arrange. The displacement device 19 is on the inlet side of the threads 30 in the winding device before or after the traversing device 18 to arrange. The displacement device preferably consists of a rail 194 which by a drive 192 according to the double arrow 19 in the longitudinal direction of the rail 194 can be moved. The displacement device 19 must also continue across the longitudinal extent of the rail 194 can be moved, according to double arrow 192 what a lateral drive 192a serves. In the schematic representation in 2 B is the drive 192 at the end of a push rod of a transverse drive 192a stored, bringing the movements of the displacement device 19 in the axial direction of a coil 32a or can cross over to it. The displacement device 19 is only during the change process of a fully wound coil 32a on an empty sleeve for attaching the thread to a sleeve 32b necessary, as described below.

In 1c essential parts of the drives of the winding device with control components are shown schematically. The control device 40a is over a bus 40b connected to actuators and sensors, wherein the connecting lines to the sensors are shown in dashed lines, while the control lines are extended to the actuators. The rotary drive 164 for the revolver is shown attacking on the circumference of the revolver. It can be implemented as a DC motor with a gearbox, or for example as a hydraulic drive, which has a toothed rack on an outer toothing on the circumference of the revolver 16 attacks. The rotary actuator can also be designed as a servo motor with gearbox or as a pneumatic drive. For position control of the revolver 16 serves a position sensor 70 , which is located on the outside of the revolver and can detect marks on the circumference of the revolver. These markings can be formed for example by teeth. To hold the revolver in certain positions, there are at least two locking positions 92 , shown as notches, provided on the revolver 16 lying diametrically opposite. Only one of the locking positions is shown. The locking device 90 bring the revolver 16 in a resting position by a wedge 90 in the notch 92 is retracted, with the aid of an actuator on the locking device, such as a pneumatic cylinder or a solenoid. For actuating the locking device 90 for example, via the controller 40a a valve 90a actuated. The revolver 16 is at the beginning of the winding on the mandrel 12a or at the mandrel 12b to keep locked while the rubbing roller 14 on the swivel arm 140 is mobile. In this phase at the beginning of Spulenbewicklung the rotary actuator 144b applied. The movement of the swivel arm 140 can through a position sensor 74 be detected, further the torque generated by the rotary actuator 144b is applied by means of the torque sensor 76 , For the swivel arm 140 with the rubbing roller 14 is analogous to the revolver 16 a locking device 94 similar to the locking device 90 can be executed. The locking position of the pivot arm can in at least one position by a notch 96 be defined. On the other hand, a locking of the swing arm 140 also about a stop 148 possible, against the swivel arm by means of the pivot drive 144b according to 1a can be pressed. The locking device 94 is actuated, and thus the swing arm 140 with the rubbing roller 14 detained when the revolver 16 by means of the rotary drive 164 is rotated, wherein the locking device 90 of the revolver 16 is in the released position. The rotary actuator 144b can be analogous to the rotary drive 164 of the revolver 16 be executed, namely as a DC motor or servomotor, each with gear, or as a pneumatic or hydraulic cylinder, via a linkage or a rack on the pivot arm 140 attacks.

It can also be a torque sensor 82 on a rotary drive 124 of the mandrel 12a as on the other mandrel 12b be attached, further a torque sensor 80 at the drive 144a the rubbing roller 14 , Furthermore, the slip or the rotational speed of the friction roller by a speed sensor 78 and another speed sensor 79 , on the one hand, on the rubbing roller 14 , on the other hand on the spool 12a , determined or by feedback via the control device 40a to be influenced. Together with a timer 100 that's over the bus 40 to the control device 40a can be connected through the speed sensors 78 and 79 the thread delivery in the control device 40a be extrapolated, so that the operator of the winding device, the total wound on a mandrel amount of thread 12a can set. The locking devices 90 and 94 are to be operated alternately, being at the beginning of the winding of a mandrel 12a the locking device 94 the swivel arm 140 releases while the revolver 16 through the locking device 90 is fixed, and in another phase of winding the mandrel 12a the locking device 90 in their release position according to 1c remains, and the locking device 94 the swivel arm 140 in the locked position 96 holds. By determining the torque on the swivel arm 140 by means of the torque sensor 76 or by determining the torque of the rotary drive 164 of the revolver 16 by means of the torque sensor 72 can the contact force between the friction roller 14 and a mandrel 12a being regulated over the entire length of the winding, whereby also a pure control of the torques of the revolver 16 or the swivel arm 140 is alternatively possible, waiving the feedback of signals from the torque sensor 72 respectively. 76 to the control device 40a ,

The following is the changing process of winding a coil 32a on a still unwound sleeve 32b based on 2a . 2 B and 3a such as 3b described. During the change process, the revolver leads with its yoke 160 , driven by the shaft 162 , a rotary movement according to arrow in 2a counterclockwise, with the coil almost completely wound 32a down and the still empty sleeve 32b reaches the top. During the pivoting movement of the yoke 160 of the revolver 16 Both waves 122 of the first mandrel 12a and the second mandrel 12b counterclockwise according to 2a driven. Here is the rubbing roller 14 out of function, and the swivel arm 140 is at the stop 148 according to 1a at. The attachment of the thread or threads takes place on the mandrel 12b itself, and on synchronization not on the sleeve 32b which is on a mandrel 12b sitting. This method will be described below. Of course, the thread can also be directly on the sleeve 32b be used if it has a safety gear.

Before actually changing the winding on the mandrels 12a respectively. 12b that is, before the transition of the winding of the coil 32a and subsequently the sleeve 32b , the mandrel becomes 12a by means of a second displacement device in the longitudinal direction of the shaft 122 or the mandrel 12a moved from the position "0" on the position "1" in the position "2", in 2 B indicated by dotted, dashed or bold lines tet. This second displacement device has been described in connection with the description of 1b exemplified as a sledge 128 called drive, which carriage the storage 126 and thus also the wave 122 with the mandrel 12a displaced in the longitudinal direction.

As mentioned above, a bobbin becomes 12b according to the 1a and 1b each in the upper position near the friction roller 14 with threads 30 wound. After completion of the yarn package on a bobbin 12b the turret is rotated counterclockwise about 180 ° ge, resulting in a wound mandrel position 12a according to 1a or 1b results. At the same time a previously lying down spool is pivoted upward. The string 30 or several threads 30 is or are still wound during the down pivoting on the spool (n), while the still empty bobbin mandrel 12b according to 2a the thread 30 in this position between the coil 32a and the displacement device 19 is shown approximates. For applying the thread 30 on the still unwound spool 12b Two preparations are necessary: the thread must not be engaged with the traversing device 18 to be brought. This is accomplished by the displacement device 19 , according to double arrow in 2a , so moved against the thread that he is from the traversing device 18 is lifted. The movements of the traversing device 18 and the displacement device 19 have to be done so that the thread 30 in a leadership score 194a the displacement device passes.

The functions "lifting" and "shifting" of the thread can be carried out mechanically separated, by a Abhebeblech with Anschlieb in a direction transverse to the axes and a sliding device or a sliding plate with a yarn guide with drive in the axial direction. The lifting of the thread 30 from the traversing device 18 is through the cross drive 192a at the displacement device 19 according to the 2 B allows. After lifting the thread 30 from the traversing device 18 becomes the drive 192 moved so that the thread passes from a position "0" through a position "1" to a position "2." The thread is pulled out for the position "0", dashed for the position "1" and for the position "2 "shown in bold. The leadership score 194a moves away from the yoke 160 of the revolver 16 , While in the schematic representation after 2 B the thread moves to the right, he would look in the view 1b to the left of the yoke 160 remove.

2d shows the yarn path on the input side of the winding device 10 near the traversing device 18 , similar 2a in the upper part. The string 30 is pulled out in normal winding position and dashed lines for the Aushebeposition. For lifting, the lifting device 19a , preferably designed as an angled sheet, according to the short arrow at 19a pivoted counterclockwise or moved to the left. This is where the thread gets 30 in the dashed position, as it at the angled part of the lifting device 19a rests. The Aushebevorgang still occurs during the winding of a coil or while the traversing device 18 laid the thread transversely to the drawing plane, with the help of a yarn guide 18 ' which is moved perpendicular to the plane of the drawing. As mentioned, the traversing device 18 also be designed, for example, as a grooved roll, wherein the thread 30 or a leader for the thread in the groove of the roller is running. After lifting the thread becomes the shifting device 19b in the axial direction, transversely to the plane, shifted, with the between the lifting device 19a and the rubbing roller 14 Tensioned thread in a guide notch 194a the displacement device 19b arrives. It can then be moved outside of the traversing range into or into the area of the positions "0", "1", "2" required for the new setting up.The movements in the axial direction of the thread guide 18 ' or the displacement device 19e are each indicated with two adjacent circles, one of which is provided with a cross.

As a general rule It should be noted here that said axial displacements in the range the positions "0", "1", "2" are not so have to, stopping the movement at these positions has, or that the movements take place exactly in this area have to.

Simultaneously or slightly out of phase, the coil moves 32a with the mandrel 12a also according to 2 B to the right - or according to 1b to the left, causing the piece of thread between the spool 32a and the guide score 194a essentially translational and in the direction of the axes of the mandrels 12a . 12b or the traversing device 18 is moved. At the latest in the in 2a with "2" bold drawn position of the yoke 160 of the revolver 16 must be the position "2", ie to the right in 2 B moved, the mandrel 12a and the coil 32a be reached so that the thread continues to work properly on the spool 32a is wound and thus the subsequent piecing process can proceed as desired. Analogous to the thread positions "0", "1", "2", in the upper part of 2 B , is also the coil 32a shown in three different positions "0", "1", "2", namely dotted, dashed and bold 32a or the mandrel 12a done with the help of the carriage 128 with drive. For the actual application of the thread on the still unwound spool mandrel 12b this is according to 2a from the extended position to the gestri smile moves drawn position. At the same time leads the spool 12a with the coil 32a an opposite movement, since he is on the same yoke 160 like the spool 12b is attached.

For applying the thread 30 in the dashed position according to the 2a and 2 B becomes the displacement device 19 or the mandrel 12a or preferably both the displacement device 19 as well as the mandrel 12a according to 2 B moved to the left away from the position "2", causing the thread 30 at the plant on the not yet wound spool mandrel 12b is moved to the plant or in a safety gear. For this it is necessary that the thread 30 as in 2a shown in phantom, the mandrel 12b wraps. In this phase, the mandrel or the coil 32a according to arrow in 1a still driven, and also is the rotary drive 124 for the mandrel 12b already turned on, leaving the thread 30 from the spool 12b is detected as soon as it is in the area of the safety gear 12e located. The safety gear is as in 2 B indicated, preferably on the spool 12b arranged. Alternatively, the safety gear could also be on the sleeve 32b , which on the mandrel 12b is deferred. In this case, the catch process of the thread would not be in the in 2 B dashed line position of the thread 30 but done in the extended position.

2c shows schematically the first-time piecing process of 2 parallel yarns to a bobbin 12b , The strings 30 are not like in 2 B over an already wound spool mandrel 12a but submitted by a suction device 50 , a negative pressure gun held. For attachment to the mandrel 12b they must additionally be guided via an auxiliary displacement device; this takes over the role of a previously wound mandrel 12a as in 12a , The strings 30 lie in guide grooves 194'a a rail 194 ' , according to the displacement device 194 , In 2a is the location of the auxiliary displacement device 19 ' shown at the first startup process; she must do so according to the double arrow 19 ' swung to the right, while it is otherwise out of action pivoted further left. For pivoting, a drive similar to the rotary actuator 144b be provided. The actual attachment is the auxiliary displacement device 19 ' by means of a displacement device or a further drive 128 ' in the direction of the arrow 194'a shifted, according to the displacement of the full spool 12a in 12a , causing the taut threads 30 from the spool 12b as described above.

The following is based on the 3a and 3b the piecing process described in detail. 3a shows a detail of the spool 12b right in 2 B , while 3b a meridian section through the arrangement in 3a is. As mentioned, the thread becomes 30 according to 3a or 2 B in the dashed position over part of the circumference of the spool 12b strained to the left as indicated by the arrow 30 moved until he was in the area of the safety gear 12e arrives. The shift is as mentioned on the one hand by the backward movement of the spool 12a from the position "2" direction position "0" and preferably also by a same direction movement of the displacement device 19 caused. The thread now enters a groove 12c on the mandrel 12b because it forms part of the circumference of the mandrel 12b according to 2a touched in the dashed position. As the mandrel rotates counterclockwise, the thread will continue to move in the direction of the arrow 30 in 3a from a knife 12d captured that over the groove 12c in the circumferential direction of the mandrel and with its tip in the direction of rotation of the mandrel 12b lies. The thread is going through the down according to 3a directed point of the knife 12d on the circumference of the spool 12b held and thus rotates with the surface of the mandrel 12b counterclockwise. Common are also sliding clamping elements in a groove to hold the thread under centrifugal force. During the further movement of the mandrel 12a or the displacement device 19 the thread is moved further to the left on the circumference of the mandrel 12b and subsequently to the sleeve 32b wound. In this way, the thread piece between the mandrel 12b and the mandrel 12a , in 2a shown dashed, overstretched, so that the thread tears off in this area. It is understood that the tearing off of several parallel threads between the mandrel 12b and the mandrel 12a essentially simultaneously. During the further rotation of the mandrel 12b counterclockwise in 2a can a thread reserve 30c on the circumference of the sleeve 32b be wrapped. Then the normal Bewicklungsvorgang the sleeve 32b done, including the traversing device 18 again engaged with the thread 30 must be brought. This happens because the displacement device 19 out of engagement with the thread 30 is brought by moving in the direction of the double arrow to the left 2a from the thread 30 moved away. This is done by the cross drive 192a according to 2 B accomplished in the left upper part, which transverse drive on the displacement device or the rail 194 with the drive 192 acts, so the rail 194 transverse to its longitudinal extent according to 2 B in the direction of the double arrow 292 is moved upwards. This is the change process and the attachment to the sleeve 32b finished, and the drive of the spool 12a So the engine 124 , be shut down, and the sled 128 with drive, so the two te displacement device, can be in the original in 2 B left or in 1b right initial position to be reduced, the normal winding position of the mandrel 12a equivalent. Thus, the mandrel 12a in an axial position suitable for subsequent wrapping after application of the thread 30 is required, and that of the position of the sleeves 32a and 32b in 2 B equivalent.

An essential feature of the invention is therefore that the thread 30 to attach according to arrow 12b in 2 B or as indicated by the arrow 12e in 3a in the axial direction of the mandrel 12b towards a sleeve 32b is moved, causing the thread in the safety gear 12e and subsequent wrapping of the sleeve 32b is moved to this, caused by a shift of the fully wound mandrel 12a and / or the displacement device 19 in the direction of the revolver or the yoke 160 of the revolver 16 ,

In contrast to the described prior art, it is important in the attachment method according to the present invention that the piece of thread to be attached to the circumference of the still unwound mandrel 12b in an extended position between the fully wound mandrel 12a and the displacement device 19 is held, and that by moving the full bobbin 12a or the displacement device 19 or the spool 12a and at the same time the displacement device 19 essentially in the direction of the axis of the still empty bobbin 12b the thread in a stretched position, but over the surface of the bobbin 12a curved so shifted that the thread piece 30 on the circumference of the spool 12a safely into the catcher 12e arrives. It is advantageous if the thread transverse to the axis or to the shaft 122 of the spool 12b which is due to simultaneous and equally displacement of both the full spool and the shifting device 19 given is.

Furthermore, the following properties in addition or in a modification for a winding device of importance:

• - According to 2a are the running directions of the mandrels 12a and 12b counterclockwise, also the direction of rotation of the revolver 16 or the yoke 160 and the wave 162 of the revolver. It is also possible to specify the direction of rotation of the revolver in a clockwise direction. In this case, one speaks of an opposite catch of the thread to be applied, while the method described in detail is called Gleichlauffangen.
• For the traversing, any method may be used, in particular a counterbore shaft to be driven about its axis, a vane or a pointer, the former being set in rotation and the latter making a reciprocating motion, or a belt, Pointer or belt is provided in each case a thread guide for the thread to be changed.
• - The evasive movement of a mandrel relative to the rubbing roller 14 can be arbitrarily controlled or regulated, for example, the friction roller 14 on a swivel arm 140 sitting, or on a sled, and taking the mandrels 12a or 12b either rotatably mounted directly on the revolver, or on pivot arms, which in turn rotatable in the revolver 16 or in the yoke 160 are arranged.
• - The displacement device 19 can as described as lifting or sliding plate 19 be executed, or as a pointer, wherein the pointer moves substantially transversely to its longitudinal axis relative to the yarn path.
• - The displacement device 19 can be set in its longitudinal extent in at least three positions, namely: position "0": the guide notch 194 the thread is within the traversing range of the traversing device 18 , Position "1": the guide notch 194a is about in the plane in which the thread reserve 30c is formed. Position "2": the guide notch 194a lies from a sleeve to be wound 32b Seen from beyond the catch level or the safety gear 12e ,
• - The spool pins 12a and 12b are axially at least in two positions corresponding to the possible positions of the displacement device 19 movable, wherein these positions can be defined as follows: Position "0" means that a coil edge just at the reversal point of the traversing device 18 this is the working position of a bobbin 12a . 12b during coil formation corresponds. Position "1": the spool edge, according to 2 B , the right end face of the coil 32a , lies to the right of the safety gear, at the level of the thread 30 in the dashed position according to 2 B or in front of the thread reserve level, ie to the right of the thread reserve 30c according to 3a , Position "2": the spool edge is to the right of the safety gear 12e and also to the right of the corresponding position "2" of the guide notch 194a , So the position "2" of the displacement device 19 , as in 2 B shown.
• - The positions "0", "1" and "2" of the guide notch 194a or the right end face of a mandrel 12a . 12b can therefore according to 2 B be exactly above one another or slightly offset from one another. It is essential that the thread 30 when catching, so in height of the safety gear 12e according to 2 B substantially perpendicular to the axis of the spool 12b lies. After winding on the spool 12b , and after the tear of the threads between the spool pins 12a and 12b becomes the spool 12a braked, and it can be the wound sleeves, so the coils 32a from the mandrel 12a be deducted, and this will come with new sleeves 32b equipped, whereupon this spool remains in its rest position until the spool 12b is fully wound and the next change process is initiated.

The following will focus more closely on the control of the essential elements of the updraft device 10 received during the coil formation, based on the schematic motion sequences or the courses of other sizes in 4 and the representation in 2a in which the in 4 listed sizes are registered. The entire process is divided into four phases Ia, Ib, IIa, IIb, wherein the following quantities are qualitatively recorded over the time axis t:

D

Diameter of the yarn winding on the spool 12b

S

Gap height between the rubbing roller 14 and the new coil to be formed

F

Contact pressure between the rubbing roller 14 and the spool 12b

WT

Angle of rotation of the swivel arm 140

WR

Rotation angle of the revolver 16

MT

Drive torque on the swivel arm 140

MR

Drive torque on revolver 16

In the first movement phase Ia, the angle of rotation of the swivel arm 140 Zero, being at the stop 148 according to 1a is applied. Between the rubbing roller 14 and the mandrel 12b or the surface of the yarn package on the sleeve 32b If there is a gap, according to 4 gradually decreases and becomes 0 at the beginning of phase Ib. Next is the revolver 16 locked, so that the rotation angle WR is 0. The revolver moment MR is 0 because of the revolver 16 is arrested during phase Ia as well as in phase Ib.

At the beginning of the phase Ib, the friction roller touch 14 and the new coil on the mandrel 12b , The rotation angle of the pivot arm of the friction roller WT increases continuously, according to the growing bobbin diameter on the bobbin 12b , The revolver 16 is still locked. During phases Ia and Ib, the torque MT of the friction roller is controlled or regulated; the setpoint value is continuously recalculated so that, taking into account the geometrical conditions and the mass of the system, the contact pressure F assumes a desired value from the beginning of phase Ib. The course of the torque MT can follow, for example, the dashed line or the solid line.

At the beginning of Phase IIa, the locking of the revolver is canceled. During phase IIa, the angle of rotation WT of the friction roller increases 14 back to 0, while the rotation angle of the revolver 16 increases. The torque MT in the rotary actuator 144b is also increasing. The torque MR in the rotary drive 164 of the revolver 16 also increases in a controlled or regulated manner. In this case, the desired value of the torque is continuously calculated, or taken from a table, so that taking into account the geometric conditions and the masses of the friction rollers 14 as well as the swivel arm 140 , continue the mass of the coil mandrel 12b and the coil 32a the contact force FP assumes a desired course.

Of the Course of the contact force F over The winding travel is the user of the winding device as a setpoint curve given in the simplest case, the course of the curve a plurality of straight sections with a certain number of supporting points, for example four, is composed.

When determining the default values for the torque MR or MT, the following procedure can be used:
A spool 12a is wound in sections; At different diameters, the contact force between the spool and the friction roller is measured, and the torque on the revolver is set and recorded in such a way that desired values of the contact force F assigned to the respective diameter of the winding result.

Analogous can the torque curve for the Semi-rotary drive of the friction roller can be determined for the first phase of the winding cycle.

• – die Massen der beteiligten Elemente am Spuler
• – die Massen des Fadenwickels
• – die Geometrie der Elemente

Alternatively, the course of the torques from the desired curve of the contact force is calculated analytically. This calculation is included

• - The masses of the elements involved in the winder
• - the masses of the filament winding
• - the geometry of the elements

The calculation of the courses can during operation in the control device 40a be carried out, or the individual values are stored in a data memory of the controller.

During the movement phase IIb the friction roller remain 14 and the coil 32a on the mandrel 12b in touch. The rotation angle of the swing arm of the friction roller WT is 0, so that the increase in the diameter of the coil 32a alone from the rotation of the revolver 16 Compensated. The torque MR is to hold so large that the coil 32a with a desired contact force permanently to the friction roller 14 is pressed. During phase IIb is a lock for the swivel arm 140 to provide, or the torque MT is by means of the rotary actuator 144b so big to choose that the swivel arm 140 permanently at the stop 148 is applied. Also during this phase, the torque on the turret 16 controlled or regulated as indicated above.

During the phases Ia and Ib can on the lower mandrel 12a still coils 32a be present from the previous cycle.

In an alternative embodiment, the phase Ia can be omitted, so that without a gap between the rubbing roller 14 and the spool 12b will drive. The coil diameter can be determined during the four movement phases, for example as follows:
In the phase Ia from the material flow, taking into account the product total titre x velocity and the packing density. In the phase Ib from the diameter of the friction roller 14 and in proportion to the rotational speeds of the friction roller 14 and the spool 12b , In the movement phases IIa and IIb, the bobbin diameter becomes the diameter of the rubbing roller 14 and as mentioned from the ratio of the rotational speeds of the friction roller 14 and the mandrel 12a , b, where alternatively also a determination from the revolver position of the revolver 16 is possible.

The control device 40a coordinates the evasive movement of a mandrel 12a , b opposite the rubbing roller 14 or conversely, the rubbing roller 14 opposite a mandrel 12a , b by influencing the drives 124 . 164 . 144a . 144b , so that the contact pressure of the rollers against each other in the desired frame.

The locking of the revolver is preferably switched on during the Bewicklungsphasen IA and IB, while the locking of the pivot arm 140 during the phase IIB is in function. It may also be appropriate, the contact pressure between the friction roller 14 and the mandrel 12b according to 1a in the storage of the shaft 14a the rubbing roller 14 , according to 1a at the reference number 14a to determine by a probe. The change in the contact force F, as in 4 shown, by influencing the Schwenkarmantriebs 144b or the rotary drive 164 be achieved.

• – Die Anpresskraft F steigt sprunghaft an,
• – der Drehwinkel WT am Schwenkarm 140 steigt an, oder das Antriebsmoment im Antrieb 144a der Reibwalze ändert sich, oder das Moment MT am Schwenkarm 140 steigt an.

The timing of the transition from phase IA to phase IB may be defined by the following events or measurements:

• - The contact force F increases abruptly,
• - The angle of rotation WT on the swivel arm 140 increases or the drive torque in the drive 144a the friction roller changes, or the moment MT on the swing arm 140 rises.

The change from Phase IIA to Phase IIB according to 4 can be defined by the measurement of the rotation angle WT, or by a pure time measurement by means of the timer 100 ,
