Abstract
A contact bar assembly for the warp stop motion of a loom includes an inner bar (1) having a beam-shaped part (2) of insulating material at the upper edge of which a groove (5) is provided for the reception of a metallic serrated bar (6), and the entire inner bar can longitudinally reciprocate in an outer bar (8) of a U-shaped cross section. The outer bar (8) has longitudinally spaced slots (12) each for the reception of a guide piece (12) of synthetic material which can easily be inserted and removed, each guide piece having a longitudinal slot (13) with a larger configuration (14) at its lower section. The beam-shaped part (2) of synthetic material has a lower section of T-shaped cross-section (4) and (10) which engages with slot (13) and its larger configuration (14) for holding and guiding the inner bar (1) in such a manner that a vertical separation of the inner bar from the outer bar is prevented, although the inner bar is capable of longitudinal reciprocation in the outer bar (8). The longitudinal edge of the inner bar located beyond the free ends of the legs of the U shaped outer bar has about the same thickness as the outer bar and covers a slot (9) of the outer bar (8) to…
