Abstract
A cassette assembly line including, a tape reel leadering and placement station having a table rotatable between reel supply, leader supply/clip/cutting and tape reel placement substations. The reel supply substation places unleadered tape reels in equally spaced relation on the rotary table. The table rotates to present unleadered tape reels to the leader supply/clip/cutting substation. A first reel is fed a leader supply, which leader is secured by a leader clip. The rotary table is then rotated so that the leader supply extends across a second and third tape reel, and leader clips secure the leader supply to the second and third tape reels. The leader is then cut between the second and third tape reels to form an exact length leader for the first and second tape reels. The leadered pair is then transferred to a cassette shell by the reel placement substation. In effect, the cut end still attached to the leader supply becomes the leader for the next pair. Thus, specific rotation of the rotary table and equal radial spacing of the tape reels serve to measure the leader predictability and reliably every time so that there is no variation in leader lengths from one cassette to anoth…
