Patent number: 6387199Abstract: Fabricating belts by forcing adhesive into a belt seam using centrifugal forces. A belt having ends that are fabricated to mate along a seam is inserted into a cylinder such that a seam is formed. An adhesive is then deposited along the seam and the cylinder is spun at a speed sufficient to force the adhesive into the seam. The adhesive is then cured so as to produce a seamed belt.Type: GrantFiled: August 25, 2000Date of Patent: May 14, 2002Assignee: Xerox CorporationInventors: Antonio DeCrescentis, Ralph A.
