ABSTRACT:
An apparatus for manufacturing an endless ribbon comprises a pair of clamping devices situated spaced apart from each other along a ribbon path for overlapping two ends of a ribbon one above the other, an ultrasonic welding device for welding the overlapped portion of the ribbon along a weld line, a guide member to be inserted between the main ribbon body and superfluous ribbon end joined by way of the weld line, the thickness of the guide member on the side of the ribbon end being gradually reduced toward the weld line, and a cutter having an arcuate blade each for cutting off the superfluous ribbon end in the vicinity of the weld line in cooperation with the guide member. The endless ribbon is manufactured by a method of clamping the two ends of a ribbon overlapped one above the other, welding a central part of the overlap along a weld line, inserting the guide member between the main ribbon body and the ribbon end and cutting off the ribbon end at a position in the vicinity of the weld line.
