Abstract
A prior tape spool comprises two hub parts which are wedged together to pinch a tape leader between the walls of a narrow passage that opens through the tape-winding surface. The novel tape spool differs from the prior tape spool in that the passage pinches the leader only in a region remote from the opening through the tape-winding surface, so that if the leader is accidentally crimped or off center, it would tend to straighten out before emerging from the opening.
