ABSTRACT:
A plate winding apparatus, includes a winding rod which is rotatably received in a first groove, bearing plates, plate holding springs, levers, and plate winding springs. The bearing plates have axial holes each having a diameter larger than that of each of both end portions of the winding rod and pivotally support the winding rod and movably support the winding rod in a direction to increase a distance between the winding rod and a inner wall surface of the first groove. The plate holding springs are fitted in holes formed in a circumferential surface of the winding rod in an axial direction thereof and bias the winding rod against the inner wall surface of the first groove. The levers are fixed on the both end portions of the winding rod. The plate winding springs are arranged between free ends of the levers and plate cylinder end faces and apply pivotal forces in a plate tightening direction after the levers pass over dead centers thereof on the way of pivotal movement of the winding rod in the plate tightening direction.
