ABSTRACT:
A hub/tape clamp arrangement for tape-like or strip-like articles consists of a recess in the peripheral edge of the hub, having one or more middle projections, and a tape clamp having the shape of an inverted W. In practice, wedge-shaped locking means between the projection and/or walls of the recess and the tape clamp may serve to retain the clamp and fix the tape. Steps at the ends of the recess, and extensions or steps in the hub recess which have been matched up in shape, increase the possibilities for monitoring/measuring dimensions. If the tape is fastened asymmetrically on one side, the tape clamp rises out of the recess on one side by a distance precisely the same as the tape thickness, so that the tape emerging from the recess is wound at the same level, i.e. the empty hub has a roughly screw-shaped peripheral contour. The hub can be designed for use with or without one or more flanges and is particularly useful for thin tapes, e.g. magnetic tapes.
