Patent number: 7780805Abstract: Belt material is wrapped around a small diameter mandrel. Instead of cutting the belt to length, the material is then continued to be wrapped around the mandrel, forming a belt material overlap, and held under tension. An ultrasonic welding horn is then traversed across the width of the belt overlap. As this horn is traversed across the overlapped joint, the horn not only joins the belt material wrapped around the mandrel but, as the trailing edge is held under tension, the horn also separates or severs the trailing edge of the material from the welded seam.Type: GrantFiled: November 14, 2005Date of Patent: August 24, 2010Assignee: Xerox CorporationInventors: John J. Darcy, III, Michael S. Roetker, David W. Martin

Patent number: 7491281Abstract: A method is disclosed that involves providing a sheet of thermoplastic belt material having a first end with a first radius of curvature, providing a mandrel having a second radius of curvature that is no more than 12% larger or smaller than the first radius of curvature, wrapping the sheet of thermoplastic belt material on the mandrel to form a material overlap region, and welding the material overlap region to form a seamed belt. In one embodiment, instead of cutting the belt to length, the material is then continued to be wrapped around the mandrel, forming a belt material overlap, and held under tension. As the ultrasonic welding horn is traversed across the width of the belt overlap, the horn not only joins the belt material wrapped around the mandrel but, as the trailing edge is held under tension, the horn also separates or severs the trailing edge of the material from the welded seam. A seamed belt is also disclosed.Type: GrantFiled: March 28, 2006Date of Patent: February 17, 2009Assignee: Xerox CorporationInventors: John J. Darcy, III, Michael S. Roetker, David W. Martin

Patent number: 7238254Abstract: A method of welding together the ends of a web segment of a thermally weldable material, such as for a xerographic photoreceptor or intermediate transfer belt, to form an endless loop belt with a welded seam, by compressing the web segment ends in a welding area with a weld-splash confining laser-light transmissive glass plate, and applying sufficient laser-light energy through that glass plate to thermally weld the web ends together into a smoothly welded seam. The side of the belt opposite from the glass plate may be held by a pneumatic holding system. The side of the glass plate pressing against the web ends may have a slightly convex parabolic shape.Type: GrantFiled: June 18, 2004Date of Patent: July 3, 2007Assignee: Xerox CorporationInventors: John J. Darcy, III, Michael S. Roetker

Patent number: 7182903Abstract: Multilayered web stock is directed toward a curved surface and at least one layer of the web stock is heated to a temperature above a glass transition temperature of the at least one layer of the web stock. The heating can occur just before or upon engaging the curved surface. The temperature of the at least one layer remains above the glass transition temperature while engaging the curved surface, allowing reshaping and/or realignment of the at least one layer relative to other layers of the web stock according to conformance to the curved surface. The web stock is cooled before it disengages from the curved surface. The heating can be done with a high power infrared lamp focused into a line across the web stock, and the cooling can be done with a cooled fluid jet. Additionally, a preheater can be employed, and a supplemental cooler can be used.Type: GrantFiled: March 7, 2003Date of Patent: February 27, 2007Assignee: Xerox CorporationInventors: Robert C. U. Yu, Satchidanand Mishra, Anthony M. Horgan, Richard L. Post, Edward F. Grabowski, Tsu-sen Chow, John A. Bergfjord, Sr., Miguel A. Boscan, John J. Darcy, III, Michael S. Roetker, Scott J. Griffin

Patent number: 5334246Abstract: A dip coat process material handling system and method for coating multiple layers of material on a plurality of workpieces, in particular for producing a multi-layer optical photoconductive drum, wherein a plurality of pipes are suspended from a carrier pallet which transports the workpieces through a dip coat cell housing various dip coating stations. The system includes a load/unload station, vertical and horizontal transport systems for transporting the carrier pallet having workpieces loaded thereon to the various dip coating stations, a drying/cooling booth, and a return conveyor system. The invention allows complete dip coat processing to be completed in an in-line configuration while the workpieces are attached to the carrier pallet, thereby eliminating load/unload steps at each dip coating station to provide efficient and flexible processing of materials.Type: GrantFiled: December 23, 1992Date of Patent: August 2, 1994Assignee: Xerox CorporationInventors: Stanley J.
