Abstract
An endless flexible seamed belt formed by joining two ends of material from which the belt is fabricated each end of which has a plurality of mutually mating elements in a puzzle cut pattern which are in interlocking relationship to prevent separation of the ends and which form a seam when joined mechanically to enable the flexible belt to essentially function as an endless belt having a substantially uniform thickness, said seam having voids between mutually mating elements at least partially filled with a seam strength enhancing material which is chemically and physically compatible with the material from which the belt is fabricated and which substance applied as a strip or on a strip over the seam and is bound to said belt material, said bond having been formed by the application of heat and/or pressure to a strip of said compatible placed material on at least one side of the seam at least substantially covering the seam. The strip may include a substrate with a coating of the compatible material which is removed after the bond is formed.
