A roller arrangement for a web processing system, the roller arrangement comprising a roller and at least one rotational shaft having a shaft portion and an attachment portion and wherein the at least one rotational shaft is releasably connectable to the roller.

A double drawcord winding device has a belt pulley supported by a belt pulley bearing to mount on a webbing wheel shaft, two one-way bearings disposed on two sides of the belt pulley bearing, a second shaft sleeve securely mounted on the belt pulley and mounted around the one-way bearings, two winding devices disposed on two sides of the belt pulley and each having a first shaft sleeve extended toward the belt pulley, inserted into and mounted in one of the one-way bearings, each winding device having a winding bearing, a pull cord and a coil spring with two ends, two locating sleeves mounted on the webbing wheel shaft and mounted in the winding devices, one of the two ends of the coil spring connected to the locating sleeve, and other end connected to the winding device.

In many continuously webbed machines, media is fed through the machine with rollers mounted to one or more rotating shafts. These shafts may be supported on each end with a cylindrical journal bearing. The rollers move at the same rate as the media to maintain traction with the media to control media position as it moves the media from one process to another through the sequence of processes in the webbed machine.

Dispenser with bearings for dispensing a roll of tension activated expandable sheet material, as well as methods for using the same.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

Disclosed is a drawing apparatus including: a base member; and a drawing member that is attached so as to be capable of being drawn and pressed in a reciprocating direction with respect to the base member, wherein the base member has a couple application mechanism that applies a couple for correcting skewing of the drawing member with respect to the reciprocating direction to the drawing member as a reaction of a force by which the drawing member is pressed, and wherein the couple application mechanism is configured so that a distance between action lines of two forces generating the couple becomes large as a pressing amount of the drawing member with respect to the base member increases.

An apparatus and method of conveying parts underneath an array of inkjet printheads in such a way as to minimize print defects caused by variation in motion. The conveyor is composed of a series of rigid conveyor track segments that are forced to move in a precise straight line due to a combination of accurate ball bearing wheel assemblies and precision machine guideways that are incorporated into the conveying system.

Disclosed herein are disposable cable payoff systems that maintain the performance standards required for operation at commercial sites, such as durability during transport from the manufacturer and cable payoff, and low resistance cable payoff. Preloaded cable reels comprising a disposable cable payoff system are also disclosed herein. Methods for providing the preloaded cables reels are also disclosed herein.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A document stacker (1) for receiving documents from a document processing device (3), wherein the document stacker comprises: a document support (4), and a frame (5), wherein the document support is attached to the frame by a linear guide means configured such that the document support is linearly movable with respect to the frame along a predetermined path of movement (7) inclined to a horizontal plane, and wherein the document stacker further comprises a load cell (14) configured to resist relative movement between the frame and the document support along said predetermined path and to emit an output signal representative of the load applied to the load cell by the document support.
