The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

A sheet post-processing device of the present disclosure is provided with a punch hole forming device, a processing tray, an ejection tray, a conveyance roller pair, an ejection roller pair, and a stiffening member. In a case where a sheet through which punch holes have been formed is to be ejected on the ejection tray without being subjected to post-processing on the processing tray, in a state where the stiffening member is retracted in a direction away from the sheet, the conveyance roller pair conveys the sheet until at least a tip end thereof reaches on the ejection tray.

A scoring apparatus includes a scoring portion having a first plate member and a pair of second plate members arranged to sandwich the first plate member therebetween. The apparatus is configured to form a score on a sheet by making an end portion of the first plate member and end portions of the pair of second plate members engage with the concave portion. The end portion of the first plate member is positioned closer to the concave portion than the end portions of the pair of second plate members.

The present disclosure is directed to a paper towel product that will capably separate from the paper towel roll as a full sheet, a half sheet or a quarter sheet. A method of making a paper towel with machine direction perforations is also disclosed.

The present invention includes a sheet transmission system, comprising: a sheet stacking unit, a sheet position adjusting unit, a sheet processing unit, and a sheet collection unit, arranged in series along a transmission path of a sheet; and one or more independent transmission units, each transmission unit provided between two adjacent units among above units; wherein the sheet stacking unit is configured to store the sheet to be processed; the sheet position adjusting unit is configured to adjust the position of the sheet; the sheet processing unit is configured to conduct a predetermined process to the sheet transmitted therein; the sheet collection unit is configured to collect the processed sheet; wherein when a sheet is transmitted along the transmission path, the sheet is subjected to at least one transition between the first-direction transmission state and the second-direction transition state; and wherein the sheet will not deflect in a vertical direction.

To provide a marking device that enables to easily find a tag determined as defective (RFID error, etc.) among a plurality of tags that are stacked or the like. The marking device to use with a sheet includes cut and raising part for forming, as a failure process, a cut and raised section to be positioned at an edge of the sheet having been found the defect.

A film perforation device including power supply means, a perforation element that has a perforation position and a withdrawal position, and means for receiving said film, wherein said film perforation device includes: a conveyor belt, having a planar surface penetrable by an above-mentioned perforation element which has a predetermined speed of movement and is arranged such as to receive the film unwinding onto the above-mentioned surface and convey same onto said surface at said predetermined speed in a predetermined direction; and a winch having a rotational axis, about which at least one supporting structure provided with a perforation element is rotatably driven. In said perforation position, said perforation element perforates the film and at least partially penetrates the planar surface of said conveyor belt.

The invention provides a punching system that has a relatively simple structure to provide an apparatus reduced in overall size and having a low profile, and can produce a high-quality punched hole while conveying a sheet. The punching system includes a punching device that has a punching member moving back and forth perpendicularly to the sheet being conveyed, a frame, and a sheet conveyance mechanism. The punching device is attached to the frame by an attachment unit in such a manner that it is movable in the sheet conveyance direction. The sheet conveyance mechanism includes carry-out rollers that sandwich the downstream end of the sheet at the start of sheet punching motion of the punching member and that are installed at positions downstream from and transversely corresponding to the punching position.

A sheet post-processing device of the present disclosure is provided with a punch hole forming device, a processing tray, an ejection tray, a conveyance roller pair, an ejection roller pair, and a stiffening member. In a case where a sheet through which punch holes have been formed is to be ejected on the ejection tray without being subjected to post-processing on the processing tray, in a state where the stiffening member is retracted in a direction away from the sheet, the conveyance roller pair conveys the sheet until at least a tip end thereof reaches on the ejection tray.

A sheet feeding device that performs sheet feeding by feeding out and cutting a continuous medium includes a carrying part that carries the medium, a detection part that detects a leading edge of the medium and a length over which the medium has been carried, a trailing edge detection part that detects a trailing edge of the medium specified by a user; and a cutting part arranged between the detection part and the trailing edge detection part, and is capable of cutting the medium or forming cuts in the medium (a perforation process). When a minimum length of the medium that is carried by the carrying part is L2, a length from the detection part to the trailing edge detection part is L3, and a length of the medium that is specified by the user is L4, when the trailing edge of the medium is detected, and when L4<L3<L2+L4 is satisfied, the detection part detects a position is L4, and the cutting part forms cuts in the medium at the position.
