Abstract
In a machine for the centerless winding of webs (2), including support cylinders (3), a holder (4) for a core on which the web is to be wound, a motor-driven spindle (11) for the axial displacement of the core holder rotatably mounted on a shaft (5) displaceable in a guide (8), (9), and means for limiting the axial length of travel of the core holder, the improvement wherein said travel limiting means includes a control shaft (15) coupled with the drive motor (12) through a step-down gearing (14), (16), a slip coupling (18), (19), (20), trippers (23), (24), for limit switches (25), (26), associated with the drive motor, and a cam (21) in whose path an abutment (22) is disposed, the step-down gearing (14), (16), having such a ratio that no more than one full rotation of the control shaft (15) corresponds to the predetermined length of travel. Thereby even after resetting the winder to a web of different width there will still be the same limits on the axial length of travel of the core holder when replacing cores.
