Flat card with toothed belt drive and upper guide for the flats

摘要

A sliding flat (7) formed from section bars for a card with moving flats driven by toothed drive belts (23,33), with upper return guides (40) for the flats. The flats are provided in their ends with pins (27) for cylindrical coupling with the toothed belts, said coupling pins projecting from the toothed belt such that it is they which rest on the return guides instead of the teeth (24) of the toothed belt.
