摘要

The winding station comprises two support wheels rotatably journalled in a frame and which are constructed as friction wheels of a friction wheel drive arrangement. These support wheels are driven by a drive motor through a winding transmission in a common sense of rotation. These support wheels are in inner contact with an annular friction wheel which performs the function of a winding core. This friction wheel comprises a cylindrical rim whose exposed inner surface is constructed as a traction surface by means of which the winding core rests upon the support wheels. Side flanges protrude from the cylindrical rim to laterally delimit the traction surface and serve for lateral guiding. A guide wheel which can be advanced into engagement with the traction surface of the winding core and retracted therefrom is arranged beneath the support wheels. The coupling of the winding core to the winding station and the decoupling of the winding core from the unwinding station is performed in simple manner by depositing the winding core upon the support wheels, respectively by lifting the winding core off the support wheels. The winding core is simple in construction and economical in fabrication.
