ABSTRACT:
The present arrangement includes a first tape leader which can be readily and automatically coupled to a second tape leader. In a preferred embodiment the first tape leader is connected to be wound on a take up reel while the second tape leader is connected to a tape to be pulled from a supply reel. The first tape leader has one end formed into a mushroom like tab with a supporting stem. The second tape leader has a locking aperture at one end thereof which is proportioned so that a wide section thereof can fit over said mushroom like tab while a narrow section thereof will accept the stem but block passage of the mushroom tab therethrough. Accordingly when the tab is passed through the wide section and the leader is moved (pulled) toward the narrow section of the locking aperture, the tab and part of the stem become locked in the narrow section. Hence the leaders are locked, or buckled, to enable the first tape leader to pull the second leader. The first and second tape leaders each have a smoothing aperture therein which provides a means to accept the bumps created by buckling the tab into the locking aperture so that the wrapped around leaders are in a smooth configuration when pulling a tape.
