Abstract
A method of welding together the ends of a web segment of a thermally weldable material, such as for a xerographic photoreceptor or intermediate transfer belt, to form an endless loop belt with a welded seam, by compressing the web segment ends in a welding area with a weld-splash confining laser-light transmissive glass plate, and applying sufficient laser-light energy through that glass plate to thermally weld the web ends together into a smoothly welded seam. The side of the belt opposite from the glass plate may be held by a pneumatic holding system. The side of the glass plate pressing against the web ends may have a slightly convex parabolic shape.
