1,126,355. Shuttleless loom. LINDAUER DORNIER G.m.b.H. 28 Sept., 1965 [3 Oct.. 1964], No. 41161/65. Heading D1E. In a loom having weft inserters that meet at the middle of the shed, the weft inserters are driven from a shaft 18 which is itself driven at both ends of the loom by a main shaft 15 driven at one end by a motor 13; weft selecting devices 8 are similarly operated by a shaft 45 driven from the shaft 18 by vertical shafts 42 at each end of the loom, and the reed is mounted on a shaft 28 oscillated by conjugate cams at both ends of the shaft 18. The shafts 15, 18, 28 are in three pieces connected by muff couplings 46, the shafts being secured in the couplings in such a way that torsion due to the motor drive being situated at one end of the loom is compensated for, and the mechanisms at opposite ends of the loom run in synchronism. Weft selectors, Fig. 5. The devices 8 at each end of the loom for presenting a selected weft to a weft inserted consist of a row of levers 53 having eyes 62 and cam followers 52. A cam 51 is slidable along the shaft 45 under the control of pattern mechanism to lift the desired weft into the path of the weft inserter. Weft inserters, Fig. 12. Weft inserter shanks of various hollow sections are described. In each case a slot along the bottom allows a toothed wheel 94 to mesh with a synthetic resin rack 112 housed in the section. The wheel 94 is oscillated through gearing by a toothed sector oscillated by conjugate cams from the shaft 18. The weft inserted shanks run between pairs of rollers and are enclosed by tubes 102, Fig. 1. |
