| 摘要 |
This invention concerns a tape transport apparatus based on the contact-winding principle and, in particular, an apparatus for generating/keeping constant the tape tension during all operational phases of the tape transport, and for the quick, trouble-free braking of each tape pack, independently of the amount of tape wound thereon. By means of magnetic braking devices allocated to each tape pack and to the capstan whose braking action depends upon the momentary diameter of the tape packs, the object of the invention is achieved technically and economically with the greatest possible success. The apparatus is applicable in all cases where tape-like material is to be uniformly wound and transported without undue stress, and in particular for magnetic tape transport systems.
