摘要： A roller particularly adapted for driving sheet material through a folding machine, which sheet material is folded by the folding machine. The roller has an elongated cylindrical body, with an axle connected to the body for rotatably supporting the body. The cylindrical body has a pair of recessed fastening flats in the body, each being adjacent to opposite ends of the body. An elongated strip friction belt has one end removably fastened to one of the fastening flats. The belt is helically wound on the cylindrical body, with adjacent edges of the belt abutting. The belt has the other end releasably fastened to the other fastening belt. The ends of the friction belt are easily released to allow the belt to be removed and replaced by a replacement belt.
