Abstract

PURPOSE: To obtain the sheet clamping with no lag during the rotation by a method wherein the rear end of the sheet entered into a recessed portion on the surface of a drum is supported between a clamp roller and a tension roller and the shiit is stretched to be tensed.
CONSTITUTION: In an illustrated state that the drum 2 is rotated in the direction shown by an arrow E and the front end of a sheet S is held by a clamp pawl 4, when a control lever 41 is swung in the direction shwon by an arrow F, its end portion 41A is brought into abutment with a support shaft 22A so that a clamp roller 22 is prevented from rotating together with the drum 2. As the drum 2 is further rotated, the clamp roller 22 is pushed up from a recessed portion 20 against an urging force of a spring 31. Thus, the sheet S is adhered on the surface of the drum under the pressing action of the clamp roller. Then, when the recessed portion 20 comes again just below the clamp roller 22, the clamp roller 22 is dropped down into the recessed portion 20 so that the rear end of the sheet is fixedly clamped. On this occasion, a lever 34 is rotated by means of a weight 35 on which a centrifugal force is applied, so that the clamp roller 22 is rotated and thus the sheet S is tensed.
