PURPOSE:To wind waste plastic film uniformly for using again, by winding the plastic film with a windup shaft, which rotates while pressed by a friction roll gear at the same circumferential speed as the linear speed of advancing machine. CONSTITUTION:A friction roll gear 3 rotating at the same circumferential speed as the advancing speed of machine A in linkage with drive wheels 1 mounted on both sides of the machine A or a support wheel 2 turning round its own axis for itself is pressed always against the outside circumference of a wind-up shaft 6 under plastic film, whose two ends are born by the machine body, to wind up the film F through rotation of the shaft 6. According to this arrangement the film F is wound always in compliance with the advancing speed of the machine A even when the film being wound increases the diameter of the shaft 6 with risks eliminated of the shaft's 6 turning quicker than the machine to cause breakage of film F or slower to cause slack in the film F, and further uniform winding throughout the length of the shaft 6 will provide possibility of using the film F again in the next operation by mounting on the multi together with the shaft 6. |
