Abstract

Disclosed is a magnaforming process designed to release and separate seamless hotoreceptors and other seamless belt structures fabricated on a process to expand or reduce the diameter of a metal cylinder and may be used as a method to separate organic and metallic coatings from the cylinder outer or inner surfaces to produce seamless belt elements.

Disclosed is a magnaforming process designed to release and separate seamless hotoreceptors and other seamless belt structures fabricated on a

process to expand or reduce the diameter of a metal cylinder and may be used as a method to separate organic and metallic coatings from the cylinder outer or inner surfaces to produce seamless belt elements.

U.S. Patents 5,021,109; 4,952,293; 4,772,253; 4,747,992; and 4,711,833 describe seamless belt and photoreceptor fabrication processes in which coatings are applied to the outside or inside surface of a drum mandrel. Various processes are employed to remove the dried coatings from the mandrel, for example, in the aforementioned patents '883 relies on air injected between the mandrel wall and seamless belt to aid in belt removal; '992 depends on the differential shrinkage between the mandrel and seamless structure to remove the belt; and '109 heats the coatings above the T, to expand and remove the belt from the mandrel. All of these belt removal processes are difficult to control, require complicated mandrels for air flow, and result in low belt yields. The magnaforming process is simple and mandrels may be resized to produce many belts.
