Abstract
1,166,753. Weft patterning in shuttleless looms. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES DE MULHOUSE. 4 May, 1967 [6 May, 1966], No. 20780/67. Heading D1E. Weft pattern mechanism for a loom in which a loop of weft is inserted halfway through the shed and then straightened out into a sling the pick includes thread guides comprising wire loops 21 A-F, Figs. 4, 11, pivoted on a vertical shaft 25 and each sliding in a separate dent of an arcuate comb 28. Weft pattern mechanism. The thread guides 21A-F are swung about the shaft 25 by corresponding pushers 45A-F carried by a reciprocating block 47; the pushers are normally out of line with the ends 72A &c of the thread guides, but one of them is rocked to operate its thread guide by an arm 75 pivoted at 77 and operated by a push rod 82. These rods 101A-C, operated by the dobby, act on a wobble plate 92 and the rod 82 rests against the other side of the plate at such a position that it receives displacements according to a binary scale as a result of equal displacements imparted by the dobby to the rods 101A-C. Manipulating weft. Each weft thread, Fig. 11, runs from a bobbin 32A-F, through the wire loop of a thread guide 21, and round a fixed rearwardly-facing hook 37 to the selvedge of the fabric. As shown, the weft 32A has been selected by swinging the guide 21A clockwise, which causes the weft to enter a cutter and clamp 14 mounted on the slay; the weft is cut near the selvedge and held by the clamp as the slay recedes. The weft also becomes engaged in a hook 136 mounted on the slay at a higher level than the clamp 14. The piece of weft between the clamp and the hook 136 lies in the path of the weft inserter 3 which has a forked head to take a loop of weft into the shed. At the middle of the shed, the weft is transferred to a hooked needle (not shown) and the clamp 14 releases it to allow it to straighten out into a single pick. As the slay moves forward again,- an arm alongside the hook 136 lifts the weft out of hook so that it returns to its normal position as shown for the thread guide 21B. Specifications 1,033,329 and 985,704 are referred to.
