Abstract

This assembly comprises a "captured" leader and a reel for tape, film and the like. The reel consists of two halves molded and joined in a conventional manner. The central hub portion 10 has positive locking teeth 12 to secure the trailer 14 of a captured leader - a leader that remains in a machine after the supply reel is removed. Design of the reel halves preferably is such that only one mold is required and the halves are completely interchangeable. The central hub also contains two separate winding areas 18 and 20 - one for the leader/trailer and one for the tape (video, magnetic, film, etc.).

Captured Leader Take Up Reel

This assembly comprises a "captured" leader and a reel for tape, film and the like. The reel consists of two halves molded and joined in a conventional manner. The central hub portion 10 has positive locking teeth 12 to secure the trailer 14 of a captured leader - a leader that remains in a machine after the supply reel is removed. Design of the reel halves preferably is such that only one mold is required and the halves are completely interchangeable. The central hub also contains two separate winding areas 18 and 20 - one for the leader/trailer and one for the tape (video, magnetic, film, etc.).

The take-up reel is mounted within the machine and removal, in most instances, is not necessary. The trailer is locked into the take-up reel after it is inserted into the trailer entrance slot 16, pushed in six to eight inches, and then pulled tight. The resultant two to three internal winds of the trailer secures the "trailer tabs" to the locking teeth 12. The remainder of the captured leader is then installed within the machine in its normal manner. The leader being of a lesser width than the video tape winds itself into the leader winding area 18. Any leader interface also falls into this area and therefore provides a smooth winding area for the video tape that follows into the tape area 20.
