A conveyor includes: a receiver that detachably receives a roll-like sheet; a conveyance unit that conveys the sheet in a conveyance orientation along a conveyance surface; and a tensioner that applies tension to the sheet at a position upstream of the conveyance unit in the conveyance orientation. The tensioner includes: a frame having a groove pair extending in a first direction along the conveyance orientation; a guide having a curved surface that contacts the sheet and an engagement member pair that engages with the groove pair; a pivoting member that pivots around an axis extending in a second direction orthogonal to the first direction and parallel to the conveyance surface; a transmission member that transmits pivoting of the pivoting member to the guide; and an urging member that applies urging force including a component in the first direction to the guide.

A sheet conveyor includes: a holder that detachably holds a sheet roll; a rotation measuring device that measures a rotation amount of the sheet roll; a conveyance roller that conveys a sheet pulled out from the sheet roll held by the holder; a tensioner that is provided between the holder and the conveyance roller and that contacts with the sheet pulled out from the sheet roll toward the conveyance roller; a position detector that detects a position of the tensioner; a motor that generates driving force for rotating the conveyance roller; and a controller that controls the motor. The controller estimates a diameter of the sheet roll based on a conveyance amount of the sheet caused by rotation of the conveyance roller, a rotation amount of the sheet roll measured by the rotation measuring device, and a position of the tensioner detected by the position detector.

A sticky-layer-cleaner for removing residues adhered to a sticky flat layer includes a receptacle for a cleaning-liquid and a cleaning-roll in contact with the sticky flat layer, wherein the cleaning-roll includes an elongated carpet fabric which is helically folded around the cleaning-roll and a pile of which includes yarn tufts in loop and/or cut configuration, and the cleaning-roll further includes a helical channel along the length of the folded carpet fabric for draining the cleaning-liquid from the cleaning-roll and/or for wetting the cleaning-roll with the cleaning-liquid.

A coil feeding device and a graphic machine thereof are provided. The coil feeding device includes a roller mechanism for carrying a coiled material, a base mechanism, and a compression rod mechanism. The roller mechanism includes a shaft penetrating through the shaft hole and a tension structure disposed on the shaft. The tension structure includes a first sleeve, a second sleeve and a tapered fixing member. When the first sleeve and the second sleeve are fixed to each other, the tapered fixing member holds the shaft to achieve mutual fixation of the coiled material and the shaft. By providing the second sleeve, the first sleeve and the tapered fixing member that cooperate with each other, the coiled material and the shaft are fastened to each other quickly, thereby improving production efficiency. Through the base mechanism, the coil feeding device is directly used on existing graphic machine for material processing.

A crosslapper, a process and a formed fabric web shielding device for a cross lapper shield a formed fabric web moved in the crosslapper. The formed fabric web has a bottom side, a top side and side surfaces located at formed fabric longitudinal edges. The crosslapper includes a displaceable main carriage and a crosslapper laying belt feeding the formed fabric web in a web direction to the displaceable main carriage with the formed fabric web bottom side located on the cross lapper laying belt. The shielding device includes a housing configured to be arranged in the crosslapper and configured to cover the side surfaces of the formed fabric web located on the laying belt and being fed to the displaceable main carriage, which side surfaces extend along the web direction, to shield the side surfaces of the formed fabric web against external environmental effects.

A transfer and dispensing apparatus is disclosed for the conveying and separation of packaging material, cushions or pillows when needed by the operator. When a packer working over a conveyor receives a box that requires void fill, an operating switch such as a foot pedal is depressed to dispense pillows from the apparatus and into the box in a connected strip. When the operating switch is released, the apparatus stops dispensing pillows, separates the continuous strip of pillows along a transverse perforation in the strip, and ejects the end of the separated segment. The packer can then complete packing the box by placing the severed end of the pillows into the box, advance to the next box, and repeat the process. The transfer and dispensing apparatus may be positioned in any convenient location including adjacent to, above or attached to the inflation device.

A device for applying coiling-tension to a slit band sheet includes an upper structure that is disposed on the upper side of a band sheet which has been passed through a slitter line and slitted; and a lower structure that is disposed on the lower side of the band sheet and faces the upper structure vertically. In addition, an upper belt is stretched on an outer peripheral surface of the upper structure. A lower belt is stretched on an outer peripheral surface of the lower structure. The upper structure has a first reversing portion, an upper pressing portion, and a second reversing portion. The first reversing portion and the upper pressing portion are integrated with each other. A tension adjusting mechanism is installed on side surfaces of the first reversing portion and the upper pressing portion and a side surface of the second reversing portion.
