Abstract
A carding flat and a system for guiding and driving it in a card with moving flats driven by toothed belts, in which coupling between the flats and belts is achieved by a form fit between cavities and projections without fixed retention means, so enabling these elements to freely rotate about the coupling axis.
Claims16
A flat carding machine comprising a pair of toothed drive belts (23, 33) in laterally aligned spaced relationship spanned by flats (7) and including upper and lower drive belt flights, each flat (7) including a pair of pins (27, 27) projecting from opposite ends of each flat, said pairs of pins (27, 27) being adapted to support said flat upon laterally spaced guides (10, 10), means (26, 27', 34, 28, 28', 41, 46) for articulately coupling each flat end to an associated drive belt in the absence of fixed retention means, said coupling means including coupling cavities (26, 26', 34) of a substantially cylindrical configuration formed in said drive belts and coupling pins (28, 28', 41, 46) of circular cross-sectional configuration projecting from opposite ends of each flat, and said coupling pins (28, 28', 41, 46) being freely rotatably received in and confined by said coupling cavities (26, 26', 34).
