摘要:
There is disclosed a belt assembly including: (a) an endless belt capable of repeated cycling over rollers having a first side edge and a second side edge and defining a center region between two side regions, wherein a low friction composition comprised of a fluoropolymer covers a portion of the length of the first side edge; and (b) a belt guide apparatus which contacts the first side edge during cycling of the belt to position the belt on the rollers, wherein the low friction composition reduces the wear of the belt at the first side edge.
摘要:
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.
