A conveyor including a frame and an endless drivable conveying element, which is provided with carriers extending transversely to the intended direction of movement of the conveying element during operation. The carriers are coupled to at least one endless flexible coupling member. While at least a few carriers support pusher elements, which pusher elements are connected to guides, which are capable of co-operation with guide rails supported by the frame. During operation a pusher element can thus be moved in the longitudinal direction of the carrier in one or more selected places along the intended direction of movement during operation. Seen in cross-sectional view a carrier comprises two upwardly extending legs bounding a recess having a U-shaped or V-shaped section and being open at its upper side, which legs are interconnected by a connecting piece forming the bottom of said recess. One leg of a carrier extends over a greater height than the other leg of said carrier and the greater height leg of a carrier is provided with a wing which extends over the upper end of the smaller height leg of an adjacent carrier. |
