Abstract

This apparatus attaches tape to the spool of an assembled cartridge shell, spools on a predetermined length of tape, then cuts the tape and attaches a leader block to the trailing end of the tape. The apparatus comprises a rotary work table 9 with five work stations. After cartridges are assembled, but as shells without tape, they are fed serially to input station 1, then indexed clockwise to a wind station 2. Here magnetic tape 10, unwound from a large reel (not shown), is fed by rolls 11a, b into a thin flat tape inserter 12 and held against a support surface by a vacuum chuck 13. Pinch roll 11a has a one-way clutch and is cable connected to inserter 12 to feed tape 10 to the inserter and maintain the tape position on vacuum chuck 13.

Tape Insertion and Leader Block Attachment

This apparatus attaches tape to the spool of an assembled cartridge shell, spools on a predetermined length of tape, then cuts the tape and attaches a leader block to the trailing end of the tape. The apparatus comprises a rotary work table 9 with five work stations. After cartridges are assembled, but as shells without tape, they are fed serially to input station 1, then indexed clockwise to a wind station 2. Here magnetic tape 10, unwound from a large reel (not shown), is fed by rolls 11a, b into a thin flat tape inserter 12 and held against a support surface by a vacuum chuck 13. Pinch roll 11a has a one-way clutch and is cable connected to inserter 12 to feed tape 10 to the inserter and maintain the tape position on vacuum chuck 13. Tape inserter 12 enters an opening in the cartridge, approaches tangentially to the cartridge spool 14 and travels past the point of tangency to cause the tape to make rolling contact with the spool hub. Adhesive on the tape or hub attaches the tape to the hub. Air is then injected via 15 into the vacuum chuck, and inserter 12 is retracted. A guide-gripper device 16 is mounted on table 9 at each of the work stations. The guide-gripper is initially positioned open to allow passage of the inserter 12 during the early stage of operation at station 2; however, after retraction of the inserter, the guide-gripper members come together to guide tape 10 as it is wound onto spool 14 by rotation of the spool. A preselected amount of tape is wound onto the spool by feeding the tape from the large source reel over capstan 11b until a tachometer 17 and counter (not shown) associated with the capstan shaft determine that a preselected amount of tape has been spooled into the cartridge. During winding, pinch roll 11a is opened, and tape tension is controlled by a vacuum column (not shown), simil...
