US 6,296,587 B1 · Seamed endless belt

Abstract

Disclosed herein is a flexible seamed endless belt having high strength and good smoothness, in which the seamed portion is as thick as the other part of the belt. The seamed endless belt is formed from a flexible belt-like member by joining its ends together. The belt-link member has end structures which can be engaged with each other such that the resulting seamed portion is unseparable in the advancing direction thereof. The seamed portion is covered with a cured film formed by curing a resin composition containing a curable resin. The curable resin may be a thermosetting resin and the cured film may be formed by heating the resin composition.
