Abstract: A method of rolling out the ends of a coiled strip in a reversing rolling mill having reels disposed on both sides thereof minimizes a length of strip at the strip ends having a non-conforming thickness. A start of the strip is introduced into the roll gap without inlet side strip tension and without rolling force at the start of each reduction pass. The rolling force is then gradually increased.

An apparatus for carrying out the method on a reversing mill includes a control system which selectively controls, via regulating and adjusting devices, the inlet and outlet strip tensions and the rolling force in a manner dependent upon respective locations of the start and end of the strip.

Abstract: In a paper-punching device for use in an image-forming apparatus, the rear edge of a sheet of paper that is being transported through a transport guide is detected by the photosensor. After a predetermined time has passed since the detection, a punching device is activated. At this time, a punching member is depressed downward, and a punching blade attached to its top penetrates through the sheet of paper, thereby forming a punch hole. Even during the punching operation, transport rollers continue to rotate. Therefore, when the sheet of paper is caught by the punching blade, the transport rollers are allowed to slip predetermined amount with respect to the paper. For this reason, at least one of the transport rollers is made of a foamed material. With this arrangement, since the punching operation is carried out on the rear side of the sheet of paper, it becomes possible to reduce the occurrence of paper jams even if sheets of paper are transported in succession.

As the carriage moves across the material, the rollers roll, and the material is cut. The space between the anvil and the blade of at least one of the cutters can be varied to disengage that cutter so that the rolling of the roller will not cut the material. The engagement and disengagement of the cutter is dependent on the position of the carriage.
