Feed pull roll system with detachable elastomeric feed-roll covers and process for cover replacement
An improved elastomer covered feed roll assembly (32R) for use in a feed/pull roll set combination (36) in a sheet finishing machine (12) comprises a roll core (50) having a cylindrical surface (60) with multiple longitudinally spaced and circumferentially offset elongated keyways (80, 82, 84, 86) each configured as a locking slot. Multiple replaceable flexible feed cover sections (52, 54, 56) each incorporating a flexible backing (120) and an elastomeric layer or coating (122) are removably mounted on the roll core by locking components (74, 76) on opposite ends (70, 72) of each of said replaceable flexible feed cover sections, the locking components of each replaceable flexible feed cover section engaging a locking slot (80, 82, 84, 86) corresponding to the feed cover section. The keyways draw together the opposite ends (70, 72) of corresponding cover sections to form corresponding end joints (96, 98, 100).
CORD WINDER DEVICE
A number of illustrative variations may include a cord winder device that may include a housing that may include a first segment and a second segment. The product may further include a roller assembly positioned between the first segment and the second segment. The cord winder device may further include a lever assembly positioned between the first segment and the second segment. The cord winder device may further include a handle assembly in mechanical communication with the roller assembly. The cord winder device may be constructed and arranged to feed out or retract in cord, hose, cable, or the like.
Roll device
A roll device as a spreader roll has a rotating hollow roll tube which at the ends thereof is rotatably mounted by means of bearing ends which are mounted in rotary bearings. The roll device has a tension element which runs so as to be eccentric to the central longitudinal axis of the roll tube through the roll tube and by internal tension toward the ends of the roll tube is impinged by a force with pressure. As a result, the roll tube is capable of being bent by way of an impingement of the tension element with a force, the deflection being transversely away from the longitudinal extent of said roll tube, if the tension element is tensioned in relation to the roll tube in an axial direction.
Roller, separation device, image reading apparatus, and recording apparatus
An elastic body portion includes an inner circumferential portion and an outer circumferential portion which serves as an outer circumferential side with respect to the inner circumferential portion and a space portion between the inner circumferential portion and the outer circumferential portion, and a plurality of joining portions which join the inner circumferential portion and the outer circumferential portion to each other in the space portion, in which at least a portion of each of the joining portions has a curved shape, and in which the joining portions are each joined to the inner circumferential portion and the outer circumferential portion such that connecting portions between the joining portions and the inner circumferential portion and connecting portions between the joining portions and the outer circumferential portion do not form acute angles in the space portion.
COATER AND LIQUID DISCHARGE APPARATUS
A coater includes a coating device and a rotator. The coating device is configured to apply a coating liquid on a sheet material. The rotator is configured to contact a coated surface of the sheet material to which the coating liquid is applied in the coating device. The rotator has a plurality of fine particles on a circumferential surface of the rotator.
SHEET CONVEYANCE DEVICE AND IMAGE FORMING APPARATUS
There is provided a sheet conveyance device that includes a first conveyance roller and a second conveyance roller that are arranged at a position other than a center in a direction of sheet width in a sheet conveyance path, a roller selector that selects the first conveyance roller or the second conveyance roller as a roller to convey a sheet, and a controller that causes the roller selector to select the first conveyance roller or the second conveyance roller. The first conveyance roller is made of a material that causes a speed of the sheet conveyed by the first conveyance roller in contact with the first conveyance roller to be higher than a rotation speed of the first conveyance roller. The second conveyance roller is made of a material that causes a speed of the sheet conveyed by the second conveyance roller in contact with the second conveyance roller to be lower than a rotation speed of the second conveyance roller.
CONVEYOR DEVICE FOR A CORRUGATED WEB, CORRUGATED BOARD MANUFACTURING LINE INCLUDING THE CONVEYOR DEVICE, AND METHOD
A conveyor device for conveying a single face corrugated web on a bridge is disclosed. The conveyor device includes a lower guide roller, around which the single face corrugated web is guided. The conveyor device further includes an upper pinching and conveyance nip formed by a pair of nip members in pressure contact with one another. At least one of the nip members is motor-driven. The pinching and conveyance nip is configured to pull the single face corrugated web upwards from the lower guide roller.
BILL CONVEYING ROLLER BASE
The present invention addresses the problem of providing a bill conveying roller base having an excellent swelling resistance. In order to solve this problem, the bill conveying roller base is provided with an elastic layer covering at least part of the outer peripheral surface, the elastic layer comprising a thermosetting polyurethane which is obtained by reacting polyol components containing a lactone-based polyol with polyisocyanate components containing methylene diphenyl diisocyanate (MDI).
ROLLER FOR FEEDING AND CONVEYING PAPER SHEETS
Disclosed is a paper-sheet-feeding/conveying roller having a shaft, and a bi-layer roller material which is formed of an inner layer provided on the shaft and an outer layer. The inner layer provided on the shaft is a foamed elastic layer. The outer layer provided on the foamed elastic layer is a non-foamed elastic layer. The foamed elastic layer is formed of a foamed elastic body of silicone-modified EPDM.
