Abstract

288,531. Soc. Quevrain et Desmedt. April 8, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Circular looms; take-up motions.-The warps 40 pass from four braked warp beams 39 through holes in a guide 41 and between the teeth of a fixed comb 42 to thread guides 36, 38, which are moved up and down to form sheds to receive wefts from two or other even number of shuttles 25 by connecting rods 35, 37 and tappets 33, 34 operated by cam grooves in the peripheries of pulleys 14, 15 rotated about a fixed sleeve 3 by gearing 6, 7. A cylindrical gear 16 rotating with the pulleys 14, 15 operates pinions 17 on vertical pivots 18 carrying pinions 21 operating toothed sectors 24, each carrying a shuttle 25. The sectors move in guides 22 and are of such length as to be always in engagement with one pinion 21. The weft from each shuttle passes between a flat spring 27 and roller 26 to a guide 28 and thence to a solid barrel 30, around which the tubular fabric is formed. The fabric passes between this barrel 30 and a suspended ring or sleeve 61 and is taken up in flat form bv means of pressing and drawing rollers 54 - - 57 driven from a shaft 46 geared by belt gearing to a shaft 8. The machine may be used for covering a flexible or other tube &c. with a circular fabric.
