Patent number: 5138766Abstract: A roller for transporting sheet-like material is manufactured by forming a cylindrical resin layer on the periphery of a preheated aluminum pipe, cutting the aluminum pipe covered with the resin layer to a desired size, and joining coaxially oriented shaft end members to both ends of the cut aluminum pipe. The resin layer can be covered on the periphery of the aluminum pipe by use of an extrusion molding machine. A contoured surface on the pipe or an adhesive can help the resin adhere to the pipe. The roller thus manufactured has high stiffness, roundness, less runout and good dimensional stability over a wide temperature range. The weight of the roller is light and maintenance of a rack which is installed with the rollers by the user is easy.Type: GrantFiled: April 9, 1991Date of Patent: August 18, 1992Assignee: Fuji Photo Equipment Co., Ltd.Inventors: Tsutomu Kimura, Kenji Inoue

Patent number: 5123162Abstract: An automatic rivet feed apparatus which can be used as a retrofit to an existing power driven riveting tool or incorporated integrally into a riveting tool. A rivet strip holds each of the plurality of rivets at individual fixed positions on the rivet strip. Included is a rivet strip release hook which stops the rivets, as they are advanced one-by-one, at rivet pick-up point and releases each of the rivets from the rivet strip. A hand mounted on the end of a pneumatic ram grips the rivets at the rivet pick-up point. The pneumatic ram moves the rivet forward and rotates to place the rivet in alignment with the nose piece of the riveting tool. The pneumatic ram then retracts and inserts the mandrel of the rivet into the nose piece and returns to the rivet pick-up point to repeat the steps.Type: GrantFiled: December 6, 1990Date of Patent: June 23, 1992Assignee: Wing Enterprises, Inc.Inventors: Harold R.

Patent number: 5111566Abstract: In a controlled deflection roll having a roll shell rotatable about a stationary carrier and braced by one or more support elements against the stationary carrier, the roll shell comprises an inner roll shell part and an outer roll shell part which, during operation of the controlled deflection roll, form a press or force fit with respect to one another, for instance, due to excess pressure in the interior of the controlled deflection roll or due to elastic pre-biasing of the parts of the roll shell. Upon pressure relief or the existence of negative pressure within the controlled deflection roll a play or clearance is formed between the outer roll shell part and the inner roll shell part of the roll shell which enables dismantling and exchange of the outer roll shell part of the roll shell without the need to dismantle the controlled deflection roll or to remove such from the machine.Type: GrantFiled: June 4, 1991Date of Patent: May 12, 1992Assignee: Sulzer Escher Wyss AGInventors: Eugen Schnyder, Rolf Lehmann

Patent number: 5111563Abstract: A self-loading, controlled deflection roll for forming a pressure nip with another roll has at least one support shoe, and preferably two opposed support shoes, mounted in a stationary support shaft for controlling the deflection of the roll shell in the direction of the nip. At either end of the controlled deflection roll, a pair of opposed guide shoes are pivotally disposed on the stationary support shaft to apply pressure against the roll shell to stabilize the position of the roll shell relative to the stationary shaft. At least one guide shoe at either end of the roll is equipped with a compensating piston to permit its face surface to move radially outwardly relative to the guide shoe support on the stationary shaft. Also, at least one of the guide shoes at either end of the roll is pivotally supported on the stationary shaft to allow rotational movement of its guide shoe about an axis in a plane substantially parallel with a nip plane through the nip and the longitudinal axis of the roll.Type: GrantFiled: February 4, 1991Date of Patent: May 12, 1992Assignee: Beloit CorporationInventors: Dale A.

Patent number: 5105522Abstract: To make a friction ring which is intended to be used in clutches or brakes and has a sinter-bonded friction facing, an annular blank is blanked from flat sheet metal and is provided with a sinter-bonded friction facing. Thereafter the blank provided with the sintered friction facing is shaped to form a conical or cylindrical friction ring and grooves distributed around the periphery of the friction facing are embossed into the friction facing at the same time. In order to ensure that that shaping operation will result in an adequate dimensional accuracy, the operation to emboss the grooves into the friction facing is carried out in such a manner that the backing ring is similarly embossed.Type: GrantFiled: March 28, 1990Date of Patent: April 21, 1992Assignee: Miba Sintermetall AktiengesellschaftInventors: Johann Gramberger, Roitner Franz
