Abstract
A plurality of strands of magnetic recording tape are withdrawn in parallel feed paths from tape supply reels and are fed by a tape feed assembly at a controlled, high speed rate to a takeup assembly and wound thereat on a corresponding plurality of tape cartridge spools, of the endless tape type, that are rotated by a takeup shaft. The takeup shaft is driven at a spooling rate that is faster than the feed rate and each of the spools are drive coupled to the takeup shaft by individual, adjustable slip-clutch hub assemblies which cause the tape strands to be wound at individually adjustable spooling tensions which must be carefully regulated to insure proper operation of the spooled tapes when assembled in the endless tape cartridge. Each of the supply reels holds sufficient tape for filling numerous individual spools and as each set of spools on the takeup shaft becomes full, the strands of tape are cut and the full spools are withdrawn and replaced with empty spools. At all times during the exchange of spools, the strands of tape from the supply reels are held captive by a tape threading bar assembly which includes a plurality of tape clamps carried on an elongate bar that is mova…
