Abstract

A tape cassette is provided with a housing bearing constriction for the hubs and the support liners are provided with curved or bent liner regions which serve both for guiding the empty hub and for aligning and guiding the windings on the hub, in particular the first tape windings to be wound. Practical embodiments of the liner regions differ from one another in that they have different cross-sectional shapes and different arrangements in the longitudinal direction, tranverse direction or both or have a circular shape.
