Abstract

Apparatus for installing a tape leader on a hub, including a resilient locking member which can be projected into an undercut slot in the hub to press in a portion of the tape leader and lock it therein. A punch moves the locking member towards the hub slot, while a pair of pivotally mounted compressors move along opposite sides of the locking member to compress it and guide it into the hub slot.
