Abstract

An apparatus and process for fabricating belts wherein the leading edge of a web is conveyed from a supply roll in a straight path a predetermined first distance from a web receiving platform having a cutting edge, the web is cut at the cutting edge to form a web segment having the leading edge at one end and a trailing edge at the opposite end, the leading edge is conveyed a predetermined second distance in an downstream direction to form slack in the web, the lower surface of the web adjacent the trailing edge is inverted, the lower surface of the web adjacent the leading edge is inverted, the leading edge and the trailing edge are overlapped to form a lap joint on the upper surface of an elongated anvil having a centerline positioned substantially perpendicular to the straight path of the web to form a loop of the web segment loosely suspended from the joint formed by the overlapped leading edge and trailing edge, the loop of the web segment on the anvil is conveyed along either an arcuate path to position the joint substantially parallel to the direction of the straight path or conveyed vertically while maintaining the centerline of the anvil positioned substantially perpendicu…
