摘要

Device for reversibly pulling flexible surface structures, e.g. nets, between masts fixes the net (4) to carriages (5, 6) which move vertically on the masts (2, 3). Each carriage is coupled to a pulling cable (8, 11) which is coupled to a cable winding unit (10). Preferred Features: Each carriage is coupled with a cable pull via deviating rollers (9, 12) arranged in the upper mast region. Both pulling cables are joined to each other along a section running on the cable pulling unit.
