Abstract
In some embodiments, the drive belt for receiving the flats in a revolving flat card employs pairs of connecting elements for snap-fitting into an aperture in an end head at one end of a flat. Each connecting element has an inclined surface which extends from the body of the belt to form an acute angle of from 60.degree. to 80.degree.. The end head of each flat has a rectangular opening to receive the pair of connecting elements and has transverse molding each provided with an inclined surface to mate with the inclined surfaces of the connecting elements of the belt. In another embodiment, the drive belt employs pairs of ribs of simple rectangular section to engage within a buckle element of a flat while each rib is able to flex about a root of the rib at the belt body.
