Since the bobbin 121 is in the raised position and the thread F connected to the bobbin 121 extends to the suction tube 20, the thread run does not cross the stroke area of the traversing thread guide 126. Thus, parallel turns are formed on the bobbin 121, which are due to a corresponding, not shown design of the mouth of the suction tube 20 at a defined location with respect to the longitudinal extent of the coil 121.

  • the support of the bobbin 121 on the winding roller 120 during this working movement of the thread suction tube 3 thus leads to a defined transition from the parallel windings W 1 to the thread end reserve R, because the thread deflection made in the direction of the end region of the sleeve 125 does not extend over the clamping line between the bobbin 121 and Spooling roller 120 can also affect the parallel windings W 1 .

  • the support of the full bobbin 121 on the winding roller 120 means that the turns W 1 and W 2 are rolled to a certain extent due to the contact pressure of the bobbin 121 on the bobbin surface, which leads to the retention of the thread end on the bobbin 121 from Advantage is.
