<p>1,225,706. Weft stop motions. GEORG FISCHER A.G. BRUGG. 21 Feb., 1969 [28 Feb., 1968], No. 9602/69. Heading D1E. A longitudinally movable weft feeler 20 mounted on the sley is woven into the fabric 8 in front of the last pick 7 and, on retraction of the sley, tilts to open contacts to ensure loom operation. Absence of the last pick 7 causes the circuit to remain closed and the loom to stop. Electrical interrupter circuits are described.</p> |
