Patent ID: 6921449

Claim:
A method of manufacturing on a continuous basis quantities of seamed belts for printing systems from a continuous supply web of belt material of a given thickness, which seamed belts are manufactured to a desired predetermined defined circumference a desired predetermined defined width, comprising: forming interlockable puzzle-cut seam-forming engagement edges on the opposing edges of said continuous supply web of belt material; feeding said continuous supply web of belt material into a nip formed by a mating pair of rollers, at least one of rollers which is tapered, to spirally form said continuous web of belt material into a rotating cylinder with said web of belt material engaged edge to edge without overlapping, said rotating cylinder of said continuous web belt material having a circumference corresponding to said predetermined defined circumference of said seamed belts, said rotating cylinder of said continuous web belt material having a diameter substantially larger than that of either of said mating pair rollers, and said rotating cylinder of said continuous web belt material being automatically interlocked by mating interlocking engagement of said interlockable puzzle-cut seam-forming mating engagement edges to form a spiral seam; then adhesively sealing said interlocked puzzle-cut mating engagement edges to form a sealed said spiral seam while said web belt material is in said spirally formed rotating cylinder; and then sequentially transversely cutting off cylindrical segments of said spirally formed rotating cylinder of said belt material into a width corresponding to said desired predetermined defined width of said seamed belts; to form said seamed belts with said desired predetermined defined circumference and said desired predetermined defined width and said given thickness with said seams being angular to said width of said seamed belts.
