Apparatus for preparing belts

摘要

A process and apparatus for fabricating belts are disclosed in which the leading edge of a web is conveyed from a supply roll into a belt loop forming station, the web is cut a predetermined distance from the leading edge to form a web segment having the leading edge at one end and a trailing edge at the opposite end, the lower surface of the web adjacent the leading edge is inverted, the lower surface of the web adjacent the trailing edge is inverted, the inverted leading edge and the inverted trailing edge are overlapped 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 at the belt loop forming station is transferred to an anvil, the loop of the web segment on the anvil is conveyed to a welding station and the overlapped leading edge and trailing edge are welded together on the anvil to form a belt welded at the joint.
