Provided is a sheet supply device capable of reliably joining sheets by accurately transmitting force for joining the sheets. A joining mechanism includes a pressing roller that presses a sheet of a supply side roll against the outer peripheral surface of a standby side roll; and a moving unit that supports the pressing roller such that the pressing roller is configured to approach and move away from the standby side roll supported by a support shaft disposed at a splice position in the radial direction of the standby side roll. The moving unit supports the pressing roller such that the center of the pressing roller is movable on a straight line passing through the center of a rotation shaft and the center of the support shaft disposed at the splice position.

A controller includes: an adhesion member position determination unit that determines a position of an adhesion member in a rotation direction of a roll on the basis of the result of detection from an adhesion member detector in a state in which the roll has been rotated by a shaft control unit; and an outer diameter determination unit that determines an outer diameter of the roll in a portion where the adhesion member is positioned, the determination being performed on the basis of the result of detection from an outer diameter detector in a state in which driving of shaft drive sources are controlled by the shaft control unit such that the adhesion member is positioned within a detection range of the outer diameter detector on the basis of the position of the adhesion member determined by the adhesion member position determination unit.

A sheet processing apparatus includes a blade having a plurality of teeth aligned in a row, a mover to move in a direction in which the plurality of teeth is aligned and form a perforation in a sheet sandwiched by the blade and the mover, and a pressure device to press the mover toward the blade.

A paper dispenser including a paper input area and a paper output area; the paper input area including a holder for a paper roll and including a paper input unit provided to displace paper from the paper roll towards the paper output area, the paper output area including a paper output unit which is adapted to dispense paper to an outside of the dispenser, the dispenser further including a paper cutting unit arranged between the paper input unit and a paper output unit, which paper cutting unit is adapted for cutting the paper, wherein the paper output unit is operationally connected to the paper input unit to dispense the paper at a dispensing speed that is at least as large as a displacing speed of the paper input unit.

A medium cutting device according to an embodiment may include: a fixed blade provided on one side with respect to a conveyance path in which a medium is conveyed in a thickness direction of the medium orthogonal to a surface of the medium and including a cutting edge thereof; a rotary blade provided on the other side with respect to the conveyance path in the thickness direction, and including a cutting edge thereof, wherein the rotary blade is configured to be rotated in a rotation direction so that the cutting edge of the rotary blade passes by the cutting edge of the fixed blade to cut at a cutting position the medium being conveyed; and a guide member provided upstream of the cutting position in a conveyance direction of the medium and configured to bias the medium toward the rotary blade side.

A medium cutting device according to an embodiment may include: a fixed blade provided on one side with respect to a conveyance path in which a medium is conveyed in a thickness direction of the medium orthogonal to a surface of the medium and including a cutting edge thereof; a rotary blade provided on the other side with respect to the conveyance path in the thickness direction, and including a cutting edge thereof, wherein the rotary blade is rotatable and configured to be rotated in a rotation direction so that the cutting edge of the rotary blade passes through the cutting edge of the fixed blade to cut the medium being conveyed. The rotary blade includes, on an outer circumferential surface, a recessed portion provided on a side of the cutting edge of the rotary blade in a reverse direction opposite to the rotation direction of the rotary blade.

The subject matter of the present invention is a method and a device for producing an adhesive tape (1). First a material web (2) comprising a carrier tape material is supplied from an unwinding unit (3). The supplied material web (2) is subsequently provided on at least one surface with at least one adhesive strip (4) in a coating unit (6). The material web (2) provided with the adhesive strip (4) is then cut into at least two longitudinal strips with the aid of a cutting device (10) and made up into individual adhesive tapes (1). According to the invention, a sensor (8, 9) scanning the material web is used to align the material web (2) and/or the cutting device (10) in the transverse direction (Q) in such a way that a longitudinal cut (S) respectively produced with the aid of the cutting device (10) is introduced in an exact position into the material web (2).

The invention discloses a tape sealing machine suitable for various sizes of express boxes, including a sealing machine. The left side of the sealing machine is provided with a left telescopic cavity with an opening downward and leftward, and the left telescopic cavity can slide left and right. There is a left telescopic plate on the right side of the sealing machine, and a right telescopic cavity with an opening downward and to the right is provided on the right side of the sealing machine. A right telescopic plate is slidable in the right telescopic cavity. The right and left telescopic plates are provided with a pressing roller device. The present invention presses the sealing machine on the upper side of the express box to flatten the two cardboards at the opening of the express box, and then press the tape on the cardboard. The sealing between the seams is continued. Pressing down the sealing machine can drive the pressure rollers away from each other to the sides of the delivery box, and then flatten the tape on the delivery box. The sealing machine has good flexibility, and the pressure roller can The fixed range is large, and it can be applied to a variety of sizes of courier boxes.

Each of a first rotary blade and a second rotary blade includes a rough surface portion and a smooth surface portion. The rough surface portion has a predetermined width from a blade edge at its circumferential edge portion and has an arithmetical mean roughness of greater than 0.5. The smooth surface portion is provided radially inward of the rough surface portion and has an arithmetical mean roughness less than the arithmetical mean roughness of the rough surface portion.
