If a cotton tape 7 is cut or torn should be, the drive devices 12 and 15 controlled as follows to control the two pairs of transport rollers 9, 11 and 13, 14 with different Peripheral speeds and / or in different Turn directions so that the cotton tape 7 between tears the two pairs of transport rollers. It is e.g.
  • the device for connecting a first cotton end to a pair of press rollers 16, 17 has a second cotton end, which is driven by a drive device 18, and a movable deflecting element for at least one of two cotton ends to be joined together.
  • a movable deflecting element for at least one of two cotton ends to be joined together.
  • the deflection element in the direction of movement of the cotton band 7 in front of the pair of press rollers 16, 17 arranged slide 19 which e.g. from a cylinder-piston unit 20 is moved.
  • Fig. 1 the combing head described is in normal operation shown.
  • the cotton tape 7 is the rotation of the Winding roller 9 unwound from the winding 8, with the the same circumferential speed rotating roller pairs 13, 14 and 16, 17 fed to the combing tools 1-5 and combed out from these.
  • the cotton tape 7 is in Fig. 1 almost completely expired from the winding 8.
  • a detector device detected for example by a photocell 21, which the passage of the end 7a of the cotton tape 7 on the core 8a of the winding 8 determines by about the different Brightness and / or colors of the cotton tape 7 and the winding core 8a responds.
  • the detector device 21 outputs a signal to a control device 22 from which the drive devices 12, 15 and 18 and further drive devices described below controls in the combing machine so that automatically a winding change is carried out.
  • control device 22 actuates a cylinder-piston unit 23, which the rear winding roller 10 down pivots away, as shown in Fig. 2.
  • the almost empty winding core 8a therefore rolls under the influence of gravity on an inclined guide 24 to the rear except for one Collecting device in the form of a trough-shaped plate 25.
  • the remaining cotton tape 7 is unwound from the core 8a.
