ABSTRACT:
An adjustable connection link is provided between the dobby and the first crank lever of the control rods of each loom heddle frame. The connection link consists of two tubular bars of hollow aluminum alloy section pieces, preferably of rectangular cross-section. There is at least one internal rib that is perpendicular to the major sides of the rectangle. The section pieces, moreover, are cut away along opposing sides at their adjacent ends in order to expose the corresponding parts of their internal ribs. These are kept pressed, one against the other, in an adjustable position by a bolt. The bolt is threaded into one end of the section piece and passes through a slotted hole in the corresponding end of the other section piece.
