The present application relates to a roll replacing device and an adhesive tape sticking equipment. The roll replacing roll device replacing includes an unwinding member, a roll replacing member, a cutting member, and an end pressing member, which can realize automatic roll replacing of a work strip and a spare strip and reduce staffing, thereby reducing labor cost.

A sheet affixing apparatus includes a drawing unit for drawing a sheet from a sheet roll and a sheet cutter for cutting the sheet drawn from the sheet roll by the drawing unit. The sheet cutter includes a sheet support for supporting from below the sheet drawn from the sheet roll by the drawing unit, a cutting knife for cutting the sheet supported by the sheet support, along the sheet support, and a sheet presser for pressing the sheet against the sheet support forwardly of the cutting knife in a direction along which the cutting knife moves in cutting the sheet, when the sheet is cut.

The invention relates to a reel-up (1) for receiving and winding into a roll (5) a paper web (W) that arrives from a drying cylinder (2) in a paper making machine. The reel-up (1) comprises a rotatably mounted reel spool (4) onto which a paper web (W) can be wound to create a paper roll (5) of increasing diameter and an endless flexible belt (6) mounted for rotation along a predetermined path of travel such that the flexible belt (6) forms a loop. The flexible belt (6) is positioned adjacent to the reel spool (4) to engage the paper web (W) against the reel spool (4) during winding such that the flexible belt (6) is deflected from the predetermined path of travel when the paper roll (5) starts to build up on the reel spool (4). The flexible belt (6) is air permeable and at least one blow box (7, 8, 9) is arranged inside the loop of the flexible belt (6) such that an underpressure can be generated that draws the paper web (W) against the flexible belt (6). The at least one blow box (7, 8, 9) has at least one nozzle (10) through which air is blown out of the at least one blow box (7, 8, 9) and the nozzle is shaped as a slot. According to the invention, the at least one blow (7,8, 9) box faces the flexible belt (6) with an outer surface (11) which is convexly curved such that dust which has been sucked through the flexible belt (6) and lands on the at least one blow box (7, 8, 9) is helped by gravity to glide along the outer surface (11) of the blow box (7, 8, 9) and fall of the blow box (7, 8, 9).

An image forming device includes an image forming unit to form an image on a work, a conveyance unit to convey the work in a predetermined conveyance direction, a conveyance guide member, a suction unit, and a suction control unit. The conveyance guide member is a plate-shaped member which has a plurality of suction holes and guides conveyance of the work by the conveyance unit from below. The suction unit includes a suction device which generates suction air by sucking air in a space on an upper side of the conveyance guide member via the plurality of suction holes, and closely contacts the work to the conveyance guide member by the suction air. The suction control unit changes a sucking force of the suction device according to a length in the work width direction of the work guided by the conveyance guide member.

A plurality of folding units is arranged in a circumferential direction R of a drum that rotates about an axis. Each of the folding units includes: a pad for holding each workpiece while a center portion of the workpiece as viewed in a lengthwise direction is placed on the pad; and a first folding member and a second folding member arranged adjacent to both end portions of the workpiece respectively as viewed in the lengthwise direction and used for folding the workpiece so as to stack the both end portions over the center portion. The first folding member and the second folding member are arranged at the same position as the pad of each of the folding units as viewed in the circumferential direction, and a width direction of the drum parallel to the axis is defined in the lengthwise direction of the workpiece.

The roll replacing roll device replacing includes an unwinding member, a roll replacing member, a cutting member, and an end pressing member, which can realize automatic roll replacing of a work strip and a spare strip and reduce staffing, thereby reducing labor cost.

A conveyance apparatus includes a set unit, a conveyance unit, a first sensor, a control unit, and a platen. The set unit allows a roll sheet to be set. The conveyance unit convey the roll sheet. The first sensor acquires data to be used to identify a type of the roll sheet during sheet conveyance by the conveyance unit. The control unit controls an operation on the roll sheet based on a result of the data acquisition by the first sensor. The platen supports the roll sheet. The first sensor is disposed between a position at which the roll sheet is set and the platen on a conveyance path of the roll sheet.
