Method and apparatus for fabricating a flexible belt

A method of fabricating an endless flexible belt having a circumference L 1 and a thin seam profile. The method includes (a) cutting a work sheet of flexible belt material from a web of such material so that the work sheet has a first end and a first end region, a second end and a second end region,...

Zusammenfassung:	A method of fabricating an endless flexible belt having a circumference L 1 and a thin seam profile. The method includes (a) cutting a work sheet of flexible belt material from a web of such material so that the work sheet has a first end and a first end region, a second end and a second end region, and a length L 2 that is D units greater than L 1 ; (b) looping the work sheet and overlapping the first end region and the second end region thereof by D units to form an overlapping dual end region; (c) making a single slice through the overlapping dual end region to produce a first, male side and a second, female side of the slice, and to produce a belt-length sheet, the first, male side of the slice comprising a first, male end of the belt-length sheet, and the second, female side of the slice comprising a second, female end of the belt-length sheet; (d) looping the belt-length sheet, re-aligning and mating the first, male side and the second, female side of the single slice to form a no-discrepancy abutment; and (e) heating and fusing the no-discrepancy abutment to form an endless flexible belt having a thin profile seam including no undesirable thickness variations and no undesirable protrusions.
