<p>A flat for a revolving flat-type carding machine is disclosed which comprises a T-shaped flat body (10) comprising a flat flange (12) (to which a card clothing ''top'' (14) is clipped) and a relatively deep web (16). At each end of the flat body (10), a toothed belt (50) is engaged in exposed longitudinally extending grooves (18) and a wearing pad (24) for engagement on the flexible bend at the side of a carding machine is engaged in a dovetail shaped recess (20) provided in an underside surface of the flat body (10). Flat ends (22) which include a boss (36) which can be pushed into a recess (38) in the web (16) and a concave formation (48) provided on the top surface of a flange (34) for the purpose of engaging on guide rollers of the carding machine are provided. The flat ends (22) are secured by means of a respective set screw (40) to each end of the flat body. The screw (40) has a cylindrical head (46) which provides a nug for engagement with the teeth of sprocket wheels of the carding machine. The provision of the wearing pad (24), the flat end (22), and the nug (46) provided by the set screw (40) ensures that all the surfaces at the flat end which are subjected to wear in operation, form part of components which are easily removable and replaceable, without taking the flat off the machine. Furthermore, the belt of the flat does not extend due to wear and is easily maintained.</p> |
