Abstract

A winding hub for tape information carriers is designed with spring elements between an inner ring and an outer ring for providing a compression ratio from the inner diameter to the outer diameter of less than 1:4. To increase the holding forces of the winding hub during reeling, the spring elements are assigned limiter elements.
