ABSTRACT:
An annular flangeless winding hub for strip materials which is stackable due in particular to its plate form that is produced by an appropriately shaped circular projection and depression. As additional locking means protrusions and recesses may be provided in the depression and in the projection respectively. Apart from asymmetrical embodiments, a symmetrical design with respect to the median plane of the winding hub can be achieved by the use of upwardly and downwardly protruding ridge members which fit into one another when a plurality of hubs are stacked one upon the other. Such a winding hub can be used for any kind of material having a ribbon-like configuration, such as magnetic tape, strips of film and punched paper tape.
