Abstract

The device has multiple winding shafts, which are formed differently according to the width of a material web. The differently formed winding shafts have same overall length. The bearing sections of the winding shafts are formed at different axial positions by differently formed winding shafts. The winder has a winding receiving unit for receiving the winding shaft, which receives a winding reel (12). The material web is rolled-up partially on the winding reel supported in a pre-winding unit.

Description

The The invention relates to a device for receiving a wound one Web having winding bobbin according to the Preamble of claim 1.

Such a rewinder is out of the DE 102 97 181 T5 known. The two ends of the winding shaft or the bearing housings formed there are in this case supported in the winding receiving device on a support surface defining a carriage, which is guided along guides which are formed on a stationary support frame. An operation of the rewinder with different widths of material webs or according to different widths of winding reels or winding is not addressed here.

Another rewinder is out of the EP 14 54 858 A1 known. Here, the held between two roller arms of the rewinder core of the roll is drivable by means of drivable chuck and an engageable on the winding, non-driven, free-running application roller to ensure a bubble-free winding of the web. When converting to another web width, the distance between the roller arms is varied according to the length of the core. In order to avoid a replacement of the application roller, there is proposed to divide the application roller into several roller segments and to employ only the segments of corresponding length when changing the web width.

at Another rewinder depending on the width of the web Winding bobbins, z. B. hard cardboard tubes different Length attached to the winding shaft, the decorative pressure z. B. widths of 1,850 mm, 2,070 mm and 2,200 mm. This is the material web Due to the process driven on fixed edge, for example on the Operating side of the machine, d. H. the side facing the machine Edge of the material web has regardless of the width of the Material web always the same position. This in turn implies that at smaller widths of the material web than the maximum processable width the reel is always stored off-center in the machine, so that there is an imbalance with respect to the arrangement winding roller / winding results. This asymmetry, in turn, can especially at high winding speeds have negative effects on the winding quality, after the asymmetrically loaded winding shaft unbalanced can bend.

Of the Invention is based on the object, a device for receiving a wound coil having a wound material web to accomplish.

The The object is achieved by the features of claim 1.

The particular advantages of the invention are that now the winding shaft regardless of the width of the Material web or the length of the coil always at least essentially symmetrical and on both sides of the coil respectively can be supported near the end of the winding, so that the Bending of the flexible winding shaft always to a minimum can be reduced and an asymmetry at least substantially avoided can be, which improves the overall winding quality can be.

First, it will open 1 and 2 With reference made to the general structure of a winder of the type in question will be described, this rewinder does not have the or all features; These are then used on the basis of 3 to 11 but with reference to the rewinder according to 1 and 2 , are explained.

The rewinder comprises a machine frame 01 , on which among other things several rolls 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 are rotatably mounted, over which a material web 11 , in particular a printing material web 11 For example, a paper web 11 or, for example, a film or laminated paper / aluminum foil of a reel spool 12 , For example, a hard cardboard sleeve 12 is fed to a winding 13 to be wound up. In detail, one can be used as an inlet roller 02 , a guide roller 03 , a guide roller 04 , a measuring roller 06 , a draw roller 07 , a pendulum roller 08 and a winding roller 09 trained roller 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 be provided. The draw roller 07 and the winding roller 09 can be driven by motor, for example by means of a servo motor. For quick braking of the winding roller 09 this is at one of its axial ends with a brake disc 10 Mistake. The web tension of the drawn material web 11 is via a suitable electronics by means of the tension roller 07 , the pendulum roller 08 and the measuring roller 06 regulated. To support the roll change, a perforating device 14 be installed.

For example, as a hard cardboard sleeve 12 trained winding spool 12 is detachable on a winding shaft 101 put on and is held there in a known and not shown manner. The winding shaft 101 including winding spool 12 is in Aufwickelbetrieb against the motor-driven winding roller 09 possibly adjusted under bias and thus of the winding roller 09 driven, causing the over the winding roller 09 , through the gap between the winding roller 09 and winding spool 12 or wrap 13 and around the winding spool 12 guided material web 11 gradually to a wrap 13 is wound up. The web tension and the contact pressure generate the required winding hardness of the individual winding layers to each other.

The resulting winding 13 will after reaching its final size of a lowering device 16 supplied by means of the finished winding 13 is discharged from the rewinder, for example, to a transport device not shown for removal or further transport of the roll 13 , The lowering device 16 can as shown two by means of a hydraulic device 17 swiveling swivel arms 18 include that over a shaft 19 are drivingly connected to each other.

The hollow winding spool 12 as hard cardboard sleeve 12 may be formed, may have an inner diameter of, for example 76 mm +/- 20% or an inner diameter of, for example 150 mm +/- 20% and an axial length, for example between 500 and 5,000 mm, preferably between 1,500 and 3,000 mm, for example, an axial Length of 1,850 mm +/- 5% or of 2,200 mm +/- 5%. The rewinder is for the widest possible material web 11 or winding coil 12 designed and in the case of a narrower web 11 or winding coil 12 will be the same, in terms of their length on the longest possible reel spool 12 designed winding shaft 101 with a correspondingly shorter winding spool 12 stocked.

The tensioning of the reel spool 12 or hard cardboard sleeve 12 on a winding shaft 101 can be done in a known and not shown manner, for example via jaws or clamping strips in the winding shaft 101 are incorporated. The generation of the clamping force can be done for example via pneumatic, spring force or a mechanical threaded spindle with expanding jaws.

The rewinder is designed for a non-stop operation, ie it must be for the removal of a full roll 13 and feeding a new, with a winding spool 12 equipped winding shaft 101 not be stopped. For this purpose, the rewinder comprises a pre-winding device 102 , also "Vorwickler" 102 called a new, with a winding spool 12 provided winding shaft 101 can absorb during the previous winding 13 still bespult is finished, and further already a wrap 13 a certain initial size can produce, and a winding receiving device 103 , also "main developer" 103 in which one from the Vorwickler 102 partially wound up and handed over wraps 13 finished wound.

The pre-winder 102 comprises two together by means of an example pneumatic drive 104 swiveling swivel arms 106 around the axis of the winding roller 09 are pivotable. The swivel arms 106 have at their free ends U-shaped recesses 107 for receiving and guiding a winding shaft 101 on, with one in the swivel arms 106 recorded winding shaft 101 herein by means of e.g. B. pneumatically controlled hold-down 108 held and with the desired force in the direction of winding roller 09 is pressed.

The main developer 103 also includes two by means of a pneumatic drive, for example 114 over a wave 109 jointly pivotable swivel arms 111 at the sidewall sections 112 ; 113 of the machine frame 01 are pivotally mounted. Again, the free ends of the pivot arms 111 in approximately U-shaped recesses 116 on, for receiving and guiding a winding shaft 101 in the main developer 103 serve. In the area of the main developer 103 are the end portions of the winding shaft 101 each on one on the upper edge of the respective side wall portion 112 ; 113 trained horizontal guide rail 117 on and with increasing winding size is the winding 13 thus away from the winding roller 09 displaceable, with the winding shaft 101 in the swivel arms 111 is guided and this is the required contact pressure to the winding roller 09 is maintained.

In the case of the embodiment of the rewinder described here, an automatic reel change during production essentially takes place as follows:
In the with its U-shaped recess 107 upwardly facing prewinder 102 is a winding shaft 101 with empty winding spool 12 inserted. By means of an accelerator drive, not shown, with a gear of the winding shaft 101 engages, the winding shaft 101 Accelerated to production speed. The winding shaft 101 or the winding spool 12 is by means of the hold-down 108 against the winding roller 09 pressed and the winding shaft 101 or winding coil 12 comes in contact with the material web 11 , for example, paper web 11 , Once the paper web 11 in contact with a prepared splice on the winding spool 12 comes, tears the paper web 11 between the previous, fully wound up winding 13 and the splice off.

The acceleration drive now pivots and is switched off. The drive of the new winding shaft 101 now takes place only by friction with the winding roller 09 , where the contact pressure over the hold-down 108 is produced.

The swivel arms 111 of the main developer 103 are in a transfer position at this time as in 1 is shown. From a certain winding diameter, for example, 280 mm, the pivot arms begin 106 of the pre-winder 102 down to the transfer position to the main developer 103 to pan. At a certain winding diameter, for example, a winding diameter of 300 mm, is the pre-winder 102 in transfer position to the main developer 103 ; the storage of the winding shaft 101 lies in this phase simultaneously in the swivel arms 106 of the pre-winder 102 and the swivel arms 111 of the main developer 103 , In this phase is the U-shaped recess 107 the swivel arms 106 of the pre-winder 102 parallel to the guide rail 117 of the main developer 103 like this in 1 is shown, and the now underlying edge of the recess 107 is at the same height as the upper edge of the guide rail 117 so that the winding shaft 101 velvet wrap 13 with increasing winding diameter now on the guide rail 117 can slide along.

The winding shaft 101 is now through the main developer 103 to the winding roller 09 pressed. The contact pressure depends on the roll diameter of the roll 13 controlled. The hold down 108 of the pre-winder 102 are solved in this operating phase and are open. For a given winding diameter, for example at 430 mm, the pre-winder pivots 102 back up to its loading position, leaving a next winding shaft 101 including prepared winding spool 12 in the pre-winder 102 can be used.

The main developer 103 now pivots with increasing winding diameter in the direction of lowering device 16 , Upon reaching a predetermined winding diameter or a predetermined length of the wound material web 11 the automatic winding change takes place as described above, wherein after the gluing of the material web 11 to the winding spool 12 the next winding shaft 101 and the separation of the material web 11 the main developer 103 the wrap 13 the lowering device 16 supplies. After the main winder 103 its transfer position to the lowering device 16 has reached, the main winder pans 103 directly into its transfer position to the pre-winder 102 back.

The on the lowering device 16 overlying wraps 13 is still in rotation and is now by means of a hydraulic brake, not shown, which on one at an axial end of the winding shaft 101 attached brake disc 118 interacts, brought to a standstill. Once the wrap 13 It has come to a standstill, it can by manually pressing a on the machine control station 20 trained pushbutton by means of the lowering device 16 be lowered after removing the roll 13 is then swung back to its transfer position by pressing the said pushbutton.

The rewinder corresponds to the above rewinder in structure and function in large parts, so that reference can be made thereto. However, different in particular the formation of the proposed winding shafts 21 , the trained Vorwickeleinrichtung 22 or the pre-winder 22 , as well as the trained winding receiving device 23 or the main developer 23 that in Fol with reference to the 3 to 11 will be explained in detail.

3 to 5 each show a winding receiving device 23 or a main developer 23 , a winding shaft 21 respectively. 21a or 21 respectively. 21b receives. The winding shaft 21a according to 3 is different from the winding shaft 21b according to 4 , In particular, the winding shaft 21a for holding longer winding spools 12 or hard cardboard tubes 12 formed as the winding shaft 21b , as will be explained in more detail below.

The main developer 23 includes two carriers 24 ; 26 , each one a support 27 ; 28 for the winding shaft 21a respectively. 21b define. Every carrier 24 ; 26 is on a support frame 29 respectively. 31 held. At least one of the two support racks 29 ; 31 is in the direction of the axis of the winding shaft 21a ; 21b designed adjustable, as indicated by the arrow A, which shows the adjustment. In the case of the described embodiment, the support frame 31 adjustable designed while the support frame 29 is stationary. Also, the support frame 29 be adjustable, preferably both support racks 29 ; 31 , But it is due to the operation of the web 11 mostly not adjusted on fixed edge. The stationary support frame 29 can be arranged in particular on the operating side of the machine, while the adjustable support frame 31 can be arranged on the drive side of the machine. Thus, in the case of the embodiment, a support 28 of the main developer 23 in the direction of the axis of the winding shaft 21a ; 21b changeable and the other support 27 formed fixed in this direction.

The adjustability of the support frame 29 and or 31 can be accomplished, for example, that the corresponding support frame 29 ; 31 at certain different positions on the machine frame 01 fixable, z. B. screwed, or that the support frame 29 ; 31 on parallel to the winding shaft 21a ; 21b running, on the machine frame 01 fastened guide rails is displaceable, possibly via a suitable motor drive, and can be locked in certain functional positions.

Thus, the winding shaft 21a respectively. 21b in the area of the main developer 23 on both sides on supports 27 ; 28 stored and the distance a of the two supports 27 ; 28 is according to the width of the wound material web 11 or the winding coil provided for this purpose 12 changeable formed. Due to the variability of the mutual distance a of the supports 27 ; 28 It is possible, the respective winding shaft 21a ; 21b immediately next to the two ends of the winding coil used in each case 12 or directly next to the material web 11 to support or store close to the web edge, regardless of the width of the material web 11 or the respective length of the reel spool 12 , so that the deflection of the flexible winding shaft 21a ; 21b can always be reduced to a minimum and an asymmetry of the deflection can be at least substantially avoided, whereby the overall winding quality can be improved.

The carriers 24 ; 26 are in a plane perpendicular to the axis of the winding shaft 21a ; 21b movable, in particular rectilinearly movable, in particular free of play, arranged. For this purpose are the carriers 24 ; 26 on the respective support frame 29 respectively. 31 movably guided, in particular guided linearly displaceable, in the case of the embodiment in each case via a pair of guide rails 61 ; 62 on the respective support frame 29 ; 31 are attached, taking on the carriers 24 ; 26 with the guide rails 61 ; 62 cooperating, not shown guide rollers can be stored. The two carriers 24 ; 26 are moved together or synchronously, which can be solved in a conventional manner, also not shown manner by mechanical or electronic means, and to drive the carrier 24 ; 26 For example, a not shown hydraulic drive can be provided.

3 shows the wearer 24 ; 26 of the main developer 23 in a first position, which may be a winding or winding shaft receiving position, and 5 shows the wearer 24 ; 26 in a second position, which may be a winding delivery position, for example for delivery to a lowering device 16 (see. 1 and 2 ). 4 on the other hand shows the carrier 24 ; 26 as in 3 again in its receiving position, but now with a to the stationary support frame 29 moved back frame 31 and thus one opposite 3 reduced distance a of the supports 27 ; 28 for operation of the rewinder with a reel spool 12 smaller length or a material web 11 smaller width compared with the in 3 illustrated situation.

While in the above only two different distance positions of the supports 27 ; 28 or the carrier 24 ; 26 or the carrier racks 29 ; 31 described and illustrated in the drawing, corresponding to two different widths of the web 11 , It is understood that a plurality of different distance positions are possible, basically any number of distance positions according to any number of distance positions of the carrier 24 ; 26 or the carrier racks 29 ; 31 ,

The supports 27 ; 28 the carrier 24 ; 26 are each from one at the top of the carrier 24 ; 26 arranged bearings 32 in the form of a pair of rolls 32 namely, a spherical roller bearing pair 32 in steady rest, in the following lunette bearing 32 called, formed, which in 6 again shown in side view. As in particular from 6 can be seen, are the roles of the spherical roller bearing pair 32 arranged at least substantially in a horizontal plane. The lunette bearing 32 takes the weight of the coil 13 and allows the winding to rotate 13 ,

So that the winding shaft 21 under the effect of the force of the main winder 23 to the winding roller 09 not from the lunette camps 32 jumps, is every lunette bearing 32 one the winding shaft 21 in functional position on the steady rest bearing 32 holding locking device 33 assigned. The locking device 33 thus takes over the security of the roll 13 in the lunette warehouse 32 after the transfer from the pre-winder 22 to the main developer 23 ,

The locking device 33 can be a closing role 36 include, between an opening position in which a winding shaft 21 in the lunette warehouse 32 is insertable, and a closed position in which the closing roller 36 the winding shaft 21 in their functional position in the steady rest bearing 32 secures, is movable. The locking roller 36 can on a movable, in particular pivotable arm 34 be rotatably mounted, in particular at the end of a swivel arm 34 , and Z. B. hydraulically controlled to the winding shaft 21 be adjustable and then on the winding shaft 21 roll. In its closed position, the locking device is located 33 above the two rollers of the spherical roller bearing pair 32 and between the two roles in a 12 o'clock position, like in 6 shown. The winding shaft 21 is in the area of the supports 27 ; 28 thus each fixed in a three-point bearing.

By using the described lunette bearings 32 the further advantage arises that the previously commonly used Festloslager that on the winding shaft 101 are required to store them, omitted. These cups make it difficult to handle the winding shafts 101 and increase their weight.

As described above, the distance a between the two supports 27 ; 28 depending on the web width or length of the winding bobbin used in each case 12 variable. The winding waves 21a ; 21b are depending on the width of the web 11 or axial length of the reel spool 12 designed differently, in particular, the bearing sections 37 ; 38 , in particular winding receiving bearing sections 37 ; 38 or race rings 37 ; 38 with which the winding shafts 21a ; 21b in the supports 27 ; 28 or the lunette camps 32 of the main developer 23 rest, at least partially formed at different axial positions, corresponding to the respective distance a between the two supports 27 ; 28 , Each length of a reel spool 12 Thus, a separate winding shaft type is assigned, with correspondingly (at least partially) differently positioned bearing sections 37 ; 38 with one of the length of the corresponding reel spool 12 adjusted bearing distance.

The Wickalaufnahme bearing sections 37 ; 38 the winding shaft 21 can also be formed symmetrically. The carrier racks 29 ; 31 depending on the length of the reel spool 12 moved symmetrically.

The in connection with the 3 and 4 used winding shafts 21a and 21b are in 7 and 8th shown again. The bearing sections on the in 3 and 4 the viewer facing side, the operator side, are with 37 designated and the bearing sections on the other side with 38 , It can be seen that the bearing sections 37 on the operating side, regardless of the type of winding shaft is preferably always arranged in a fixed axial position, namely at an end portion of the winding shaft 21a ; 21b so that the material web 11 or the winding 13 with its one side is always arranged as far as possible on the operating side, while the axial position of the bearing sections 38 varied.

Preferably, it is further provided that regardless of the winding shaft type, ie, regardless of the respective different axial position of the bearing portion 38 , all winding waves 21a ; 21b each have the same overall length, which in particular simplifies handling and storage. This can also apply to "variable-width prewinders".

The winding waves 21a ; 21b are designed so that they each have only as much clamping length or clamping jaws, as for receiving a winding spool 12 the length to be used in each case is required, in other words, the length of the respective winding spool clamping section 57 the respective winding shafts 21a ; 21b is the length of the winding coil used in each case 12 customized.

While in the 3 to 8th winding shafts 21a ; 21b are shown for two different winding widths, it is understood that more than two winding shaft types can be provided, corresponding to more than two winding shaft widths, z. B. three, four or even more winding shaft types, in which at least one of the two winding receiving bearing sections 37 ; 38 is formed in each case in a different axial position and thus the respective different distances a between the winding receiving bearing sections 37 ; 38 but preferably all the same overall length.

The rewinder according to the invention further comprises a pre-winding device 22 or a pre-winder 22 , which is formed similar to the case of the rewinder according to 1 and 2 , 9 shows a part of the pre-winder 22 in its upwardly directed receiving position, together with a portion of a guide rail 39 of the main developer 23 and an end of a winding shaft guided therein 21 (shown for clarity without the associated winding 13 ). 10 shows the pre-winder 22 in its downwardly pivoted transfer position to the Hauptwickler 23 ; to illustrate the operation is here the winding shaft 21 shown in two different positions, again without the associated winding 13 ,

The pre-winder 22 comprises two opposing, together by means not shown here, for example, pneumatic drive, pivotable pivot arms 41 around the axis 42 the winding roller 09 are pivotable. In the 9 to 11 is only one of each of the two pivot arms 41 shown. The two swivel arms 41 of the pre-winder 22 are axially outside the two carriers 24 ; 26 of the main developer 23 arranged.

The swivel arms 41 have at their free ends U-shaped recesses 43 for receiving and guiding a winding shaft 21 on, with one in the swivel arms 41 recorded winding shaft 21 herein by means of e.g. B. pneumatically controlled hold-down 44 held and with the desired force in the direction of winding roller 09 is pressed.

Each swivel arm 41 has a in the axial direction of the winding shaft 21 seen axially inwardly extending, in cross-section U-shaped section 46 on, in the various guide and bearing sections for guiding and supporting the winding shaft 21 are formed, as will become apparent from the following.

For storage of the winding shaft 21 in the swivel arms 41 of the pre-winder 22 includes the winding shaft 21 two storage sections 47 ; 48 , in particular Vorwickel-bearing sections 47 ; 48 , which are assigned schwenkarmseitige bearing elements. The bearing distance between the two Vorwickel-bearing sections 47 ; 48 is always the same regardless of the type of winding shaft, ie the bearing sections 47 ; 48 are always at the same axial position of the winding shaft 21 irrespective of the respective position of the winding receiving bearing sections 37 ; 39 according to different lengths of winding bobbins 12 , In a wide variable Vorwickler, the bearing distance can also be designed differently.

The pre-winder 22 but can also be analogous to the main developer 23 be made wide variable. This has the advantage that even then the winding shaft 21 ; 21a ; 21b in the pre-winder 22 very close to the end of the sleeve or next to the paper web 11 can be included. As a result, in the case of very sensitive papers, the winding properties when winding the paper roll on the hard cardboard sleeve 12 improve because the deflection of the winding shaft 21 ; 21a ; 21b can be reduced (wrinkling). For this it is not absolutely necessary that the winding shafts 21 ; 21a ; 21b the different paper web widths then in their total length are different lengths. You only need to have one more additional inner bearing for inclusion in the "wide variable pre-winder", ie the pre-winder bearing sections 47 and 48 Be right next to the winding receiving bearing sections 37 and 38 arranged, the support sections 52 (for hold downs 44 ) right next to it. The guide section 53 stays in an existing position. The pre-winder 22 then mechanically on the support racks 28 ; 31 attached and then automatically moves with their adjustment.

The Position of the brake disc and the acceleration drive remains present on the same track of the solid prewinder. Thus, can the total length of the different winding shafts same stay.

The winding shaft 21 can in the pre-winder 22 in particular by means of the winding shaft 21 fixed rolling bearing 47 ; 48 be stored, ie the Vorwickel-bearing sections 47 ; 48 the winding shaft 21 are preferably each of at least one rolling bearing 47 ; 48 at each of the two end portions of the winding shaft 21 formed, with the rolling bearings 47 ; 48 as a ball bearing 47 ; 48 may be formed, in particular as deep groove ball bearings 47 ; 48 ,

The winding shaft 21 is with the deep groove ball bearings 47 ; 48 in grooved linear guides 49 the swivel arms 41 inserted in the relevant section 46 are trained, cf. z. B. 9 , The linear guides 49 are adjustable, allowing the game of winding shafts 21 in the linear guide 49 of the pre-winder 22 can be minimized. A winding shaft 21 is thus in the swivel arms 41 on the one hand via the rolling bearings 47 ; 48 rotatable and on the other hand for adaptation to winding on increasing winding diameter along the U-shaped recess 43 or their linear guide 49 slidably mounted.

The example hydraulically or pneumatically controlled hold-down 44 serves to secure the winding shaft 21 in the recesses of the pre-winder 22 and for pressing the coil 13 to the winding roller 09 with the desired Vorspan voltage. Every swivel arm 41 is a hold-down 44 assigned. The hold down 44 is between a release position in which the winding shaft 21 is released for loading or unloading, and a functional position in which the winding shaft 21 in the pre-winding device 22 is held in its functional position, movable, in particular designed to be pivotable. The hold down 44 carries at its free end a role 51 in the functional position of the hold-down 44 on the winding shaft 21 rolls.

On the winding shaft 21 is on both sides in each case a support section 52 formed immediately adjacent to the respective Vorwickel-bearing section 47 ; 48 is arranged, respectively on the inner side, and that of the roll 51 each of a hold-down 44 assigned. When holding down in functional position 44 thus roll their two roles 51 on the two support sections 52 the winding shaft 21 from.

The described training of Vorwickler 22 , Main developer 23 and winding shafts 21 thus results in a system where the pre-winder 22 has the maximum bearing width over all possible paper web widths, the Hauptwickler 23 however, always individually has a paper web width-dependent bearing width. The winding waves 22 all have the same overall length and the same bearing sections 47 ; 48 for the pre-winder 22 , but individually paper web width dependent bearing sections 37 and or 38 for the main developer 23 ,

Also the pre-winder 22 can be wide variable.

It will be up again 7 and 8th Referenced. Every winding shaft 21 has at least one of its two end portions a guide portion 53 for axial guidance of the winding shaft 21 in the area of the pre-winder 22 and / or the main developer 23 on. Preferably, each winding shaft 21 each a single guide section 53 on, which preferably faces the operating side of the machine.

The guide section 53 is preferably formed as a radially projecting and / or recessed portion and seen in the axial direction outside next to the Vorwickel-bearing portion 47 arranged. The guide section 53 can as a cylindrical guide section 53 be formed, in particular as a rolling bearing 53 , for example as a ball bearing 53 , in particular as deep groove ball bearings 53 , and operates in the manner described below with machine-side guide means 58 ; 59 together.
