  • the winding space 28 is delimited on the one hand by the hollow surfaces 24 of the recesses 23 of the wall elements 4 and on the other hand by a shell body 29 opposite the hollow surfaces 24, which consists of a semi-circular, thin-walled plastic shell with a smooth inner surface 30 and which is preferably at least approximately over the entire length of the two frame plates 1 and 2 limited length of the Winding space 28 extends.
  • the hollow surfaces 24 with their center of curvature Z1 have an inner radius of curvature R1 which is approximately one eighth smaller than the inner radius of curvature R2 of the shell body 29, the center of curvature Z2 of which preferably lies in the same vertical plane V as Z1 and like the center Z of the winding space 28 lying between Z1 and Z2.
  • the size difference between R1 and R2 can be one tenth to one fifth of R2.
  • the end section 22 delimiting the hollow surface 24 at the upper end has a distance a from the vertical plane V lying in the center of the winding space, which distance a should correspond to or be at least a quarter of the radius of curvature R1 of the hollow surfaces 24.
  • the winding rollers 27 are expediently made of a material with a high coefficient of friction, such as rubber or the like. or they are provided with a friction jacket made of such material, and as a functional unit they form a single one, or the winding member.
  • this shell body 29 extends from an inlet opening 31 arranged diametrically opposite the winding rollers 27 on the upper side of the winding space 28 over half the circumferential section of the essentially circular winding space 28 up to the vicinity of the winding rollers 27.
  • Das The upper end of the shell body 29 lies at the level of the inlet plane 21 and is provided with a guide plate 32 that rises obliquely upwards.
  • the shell body 29 is fastened to at least two holders 33 arranged at its ends, of which only one is visible in FIGS. 1, 2 and 4, and which are each mounted on a pivot shaft 35 by means of a sleeve freewheel 34.
  • the pivot shaft 35 is rotatably mounted in the two frame plates 1, 2 above the inlet opening 31 and thus the winding shaft 14 diametrically opposite and is provided outside the frame plate 1 with a toothed belt pulley 36, which via a toothed belt, not shown, with a separately controllable drive motor, also not shown in FIG there is a geared connection.
  • the two sleeve freewheels 34 are arranged so that the two holders 33 with the shell body 29 are freely pivotable in the opening direction of the arrow 36, so that the width of the winding space 28 can increase in the course of a roll winding by corresponding outward movement of the shell body 29 without great resistance.
  • the sleeve freewheels 34 it is on the other hand, it is also possible, by means of the drive motor (not shown) by rotating the pivot shaft 35 in the direction of the arrow 45, to pivot the shell body 29 into the opening position shown in dashed lines in FIGS. 1 and 4, so that a cutting device 18 located in the winding space 28 Roll rolls 37 already separated from the incoming fabric web can fall out of the winding room 28 and roll onto a sloping storage table 38.
  • the winding shaft 14 with the winding rollers 27 forms the motor-driven winding member, which in the winding space 28 through the inlet opening 31 in the winding space 28 along the inner surface 30 of the shell body 29 in the form of an arc tapering toward the winding rollers 27 in the direction indicated by the arrows 28 ' rolls into a roll wrap 37.
  • the friction rollers 27 which are frictionally connected to the incoming fabric web or to the outside of the roll winder 37 are driven in a non-positive, ie frictional drive connection at a peripheral speed which is approximately 1.2 to 1.5 times greater than the feed speed determined by the pair of transport rollers 5.
  • This speed difference can be achieved by a corresponding gear ratio or by a larger diameter of the winding rollers 27 relative to the drive roller 6, with which the winding shaft 14, as described above, is in gear connection via the toothed belt 13.
  • winding rollers 27 approximately vertically below the winding space center Z or the inlet opening 31 ensures that the roll roll building up rests with its full weight on the winding rollers 27, and that after the separation when the shell body 29 is opened, it automatically moves out of the Changing room 28 falls out.
  • the shell body 29 As shown in Fig. 1, it is advisable to provide the shell body 29 with a larger radius of curvature than the hollow surfaces 24. This ensures that the increasing roll 37 is no longer in contact with the hollow surfaces 24 and with the shell body 29 only a narrow area is in contact and only minimal frictional resistance can be overcome.
  • the invention provides two different devices, which are shown in FIGS. 1 and 3 or 4 and 5.
  • a pressure roller 40 which has the same diameter as the winding rollers 27, is fixedly arranged in the longitudinal center between two wall elements 4 and two winding rollers 27 on the winding shaft 14.
  • a carrier tape 41 covered with a removable adhesive film is guided over this pressure roller 40 shown in FIG. 3 and is unwound from a supply roller 43 rotatably arranged in a cassette 42 and wound up again on a winding mandrel 44.
  • the adhesive film is located on the outside of the smooth carrier tape 41 so that it comes into contact with the end portion 39 or the circumference of the roll roll 37 when it is guided over the circumference of the pressure roller 40.
  • the supply takes place through a no closer shown drive device of the winding mandrel 44, which pulls the carrier tape over the pressure roller 40.
  • This drive is controlled in such a way that when the end section 39 separated by the cutting device 18 approaches the pressure roller 40, the upper end section of the adhesive film located thereon is pressed onto the outside of the arriving end section 39 by a corresponding advance of the carrier tape 41 and then also adhered to the peripheral portion of the roll wrap 37 following the end portion 39. Then the drive of the winding mandrel 44 is stopped and the supply roll 43 is brought to a standstill or is caused to move slightly backwards while the winding rolls 27 continue to run. This will tear off the thin adhesive film. The short backward movement of the supply roll 43 then removes the torn end of the adhesive film remaining on the carrier tape 41 from the point of contact between the pressure roll 40 and the roll roll 37, so that the adhesive film is not a hindrance in the subsequent winding process.
  • an adhesive tape roll 47 is mounted on a bearing mandrel 46 below the winding device.
  • This adhesive tape 57 consists of a paper or plastic tape provided on one side with an adhesive layer, which is fed to the pressure roller 40 by a pair of transport rollers 48, which is arranged below the winding rollers 27.
  • the pressure roller 40 is provided with two resilient guide rollers 49 and 50.
  • a cutting device 51 is arranged, which serves to separate the tape sections that are required for sticking the tape sections 39 of the individual roll rolls 37 on their circumference.
  • the shell body 29 is not hindered by the guide roller 49 when it is pivoted out, it is provided with a cutout 52 in the region of the guide roller 49.
  • the pair of transport rollers 48 is started, which transports the upper end of the adhesive tape 57 between the guide rollers 49, 50 and the pressure roller 40, so that it first reaches the end portion 39 and then pressed onto the subsequent peripheral portion of the roll roll 37.
  • the cutting device 51 is actuated.
  • the pair of transport rollers 48 is stopped.
