Laying arm for a device for winding a strand-shaped winding material

In a laying arm for a device for spiral proper winding a strand-shaped winding material, such as a continuously extruded tube, preferably of plastic on a rotationally driven winding drum, the laying arm passes the winding of the winding drum at a particular substantially linear reciprocating Herverlegebewegung of the laying arm, is provided : at the winding drum end each have a side facing a sidewall flange of the winding drum abutment portion on which the laying arm in particular when performing a turning operation in abutting contact, in particular in plant sliding contact contacts the respective sidewall flange, and arranged on the winding drum end position sensor, such as a contactor, the at least upon reaching at least a predefined position of the winding drum-side end of a control signal, such as a turning operation initiating signal, and outputs the area of ​​each contact region each have a Betatigu ngsvorsprungaufweist projecting in an unactuated position of the respective contact area in outward or Herverlegebewegungsrichtung and movably, in particular pivotably, is mounted on the laying arm in that the respective operating projection releases the respective contact area for bearing contact in a release position.
