Abstract
A continuous or ring-shaped printing ribbon is constructed by overlapping the ends of a length of ribbon made of thermoplastic synthetic material and welding the overlapped ends together along a grid work of fine weld lines, thereby providing a weld joint comprising a punctiform arrangement of ink-bearing cells to effect an undisturbed emission of ink across the joint during a printing operation.
