Abstract: A mold used to form a magnetic member includes a mold body having a mold opening, a mold support that supports the mold cavity, and a mold insert. The mold insert is disposed in the mold opening of the mold body to form a mold cavity. The mold insert is coated with a coating to protect the mold body from chemical attack and abrasive wear of the mold material. The coating comprises an electroless nickel layer formed on or over the mold insert, and a chromium nitride layer formed on or over the electroless nickel layer. The mold insert can be formed of beryllium-copper (Be—Cu).

Abstract: A method of manufacturing on a continuous basis quantities of seamed belts with imageable seams for printing systems from a continuous supply web of belt material, which seamed belts need to be manufactured to a desired circumference and width. In the disclosed embodiment the sides of the incoming supply web are cut in seam-forming mating edges and the web is fed in at an angle to a pair of rollers, at least one of which is tapered, to spirally wrap the web into a cylinder of the desired circumference of the seamed belts and providing mating engagement and gluing of the seam-forming edges. Then by sequentially transversely cutting off cylindrical segments of that spirally formed cylinder into the desired width, multiple seamed belts are formed with both the desired circumference and width.

Abstract: Apparatus is provided for superpolishing the inside diameter surface of a seam of a flexible continuous photoreceptor belt.

Abstract: An imageable belt includes a seam that is finished using an abrasive finishing machine. The seam comprises a seam width with adhesive material disposed thereon. The finishing process includes an abrasive finishing media with a finishing surface and a backer bar. The backer bar comprises a backer bar radius. The backer bar surface is positioned against the belt inner surface so that the belt outer surface contacts the finishing surface to define a finishing contact arc with respect to the backer bar radius. A tension, feed rate and pressure are applied to the finishing media. Using the finishing machine, the seam is then finished to remove the adhesive material. The finishing process results in a seam that is imageable. In one embodiment, the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

Abstract: Disclosed is an inventive process for the manufacture of polymeric seamless belts, e.g. drive, fuser or toner belts for reprographics applications. The novel seamless belts can have a smooth outer surface the dimensions and quality of which are effectively determined by the inner surface of a hollow mandrel employed as a mold during manufacture. The mandrel inner surface can be highly polished to enhance the smoothness of the belt outer surface, and can be formed of a material with a lower coefficient of thermal expansion than the belt polymer to facilitate removal of the belt from the mandrel after curing. The molded belt can be used “as is”, be sliced into smaller belts or be employed as a substrate for deposition of additional belt layers and then, optionally, sliced. The polymer, e.g.

Abstract: The present invention relates to a ball valve having a housing with an axial passage way through the housing providing fluid communication between first and second ends of the housing. A rotatable ball is arranged within the axial passageway for selectively opening and closing the axial passageway. A seal is arranged within the axial passageway near the first end of the housing such that the seal is adapted to abut a surface on the rotatable ball. A blocking member is provided for selectively preventing axial movement of the seal towards the first end and for permitting axial movement of the seal towards the surface of the rotatable ball independently of the blocking member. In a preferred embodiment, the seal is arranged on a seal carrier which has an annular groove in an outer peripheral surface.
