Abstract
Abstract of the Disclosure: A flangeless stackable hub, on which compressing of the inner central bore is to be prevented during the winding up of an information medium in tape form under high winding pressure. According to one embodiment, this is achieved by an outer hub ring having a double-T profile being provided alongside the outer winding area and by there also being elastically deformable annular intermediate elements between outer hub ring and inner hub ring. In the case of another embodiment, variously shaped openings or notches, which are distributed evenly over the entire circumference, are provided on both sides of the hub between outer circumference and inner circumference. In addition, the hub contains alongside its inner circumference on both sides axial deformations, in order to avoid a shifting or twisting when hubs are stacked one on top of the other (FIG. 2, FIG. 4).
