An elongated member (11) which has a finger like protrusion (13) and a cam protrusion (15) both of which are disposed close to one end thereof. The elongated member has an elongated slot at one end which fits over a stud (19) and is further rotationally coupled to a crank (21) so that the elongated member can pivot around said stud in a number of different positions in response to the crank being moved. The crank is rotationally coupled to a cam follower (17) and the crank is further arranged to rotate about a stud (25). When a tape leader (27) from a take up reel is to be joined to a tape leader from a supply reel, the elongated member is moved toward the tape leader from the take up reel and the finger like protrusion (15) enters a first slot in the take up reel leader and moves that leader to an extended position whereat the cam protrusion (in a preferred embodiment) cams a tab (41) on the end of the take up reel leader away from the elongated member. The tab (41) is formed to have a stem section. Thereafter, the housing for the supply reel is moved toward the joining mechanism. The supply leader which is extended from the housing has a locking slot (39) therein which has a first section which fits over the tab. As the housing continues to move toward the joining mechanism it moves the cam follower which is part of the joining mechanism. In response to said camming action, the follower is partially rotated and partially linearly moved. In response to the further moving of the cam follower, the elongated member moves said finger like protrusion out of said first slot and the two leaders are joined, or buckled, to be used for pulling tape from the supply reel onto the take up reel.
