ABSTRACT:
The apparatus for unwinding flexible, substantially flat products, especially printed products, wound together with a winding strap into a wound package from such a wound package, comprises a substantially hollow and substantially cylindrical winding core and a support arrangement for rotatably and releasably supporting the winding core constructed as an annular friction wheel. This annular friction wheel is structured for deposition upon and lifting from the support arrangement. The annular friction wheel contains at its inner side a traction surface coaxial with the longitudinal axis of the annular friction wheel. This annular friction wheel also possesses side flanges extending inwardly towards its longitudinal axis for laterally delimiting the traction surface. The support arrangement comprises freely rotatable support wheels and the traction surface bears upon these freely rotatable support wheels. There is also provided a braking member structured for operatively engaging the winding core. The winding core is simple in construction and economical in manufacture.
