Abstract: 417,330. Making fabrics by stitching. MORTON, J., Tuethur, Carlisle, Cumberland. April 1, 1933, Nos. 9854/33 and 6567/34. [Class 112.] Relates to apparatus for receiving fibrous material such as threads, yarns, cords, tapes or strips of chenille and delivering this as looped stretches for use as wefts &c. in fabric manufacturing means. Endless travelling chains or like flexible members are used, which simultaneously draw out the material into looped stretches and advance these stretches. As shown in Fig. 1, two vertical feed chains 1, 2 and an inclined drawing out chain 3 provided with respective antifriction rollers 24, 25, 26 for engaging the material are so arranged and driven that the material led through a stationary guide 27 is first engaged by a roller 26 on the chain 3 and is drawn thereby between two adjacent downcoming rollers 24 on the chain 1. The chains 1, 3 thereby form the material into loops and at the same time feed these forwards. The loops carried by the chain 3 are transferred from the rollers 26 to the rollers 25 on the chain by a flexible metal brush 33 on a cam-controlled lever, the loops being thereafter fed forwards to the delivery point B, C by the rollers 24, 25 which are pivotally mounted. They are guided by guides 36, 38 which are formed at 36<1>, 38' to permit the rollers to pivot under the pull of the material and cast off the loops at the point B C. Successive stretches of material may be connected together by knitted chains of stitches in a warp knitting machine and the rollers 24, 25 of the feed chain may be arranged to reach opposite ends of the delivery zone B C alternatively, and the lowermost stretch be only fully cast off after it had been actually bound in the fabric which may be a chenille preparatory cloth. The successive stretches of fibrous material may be adhesively attached, say as wefts to a web of warps, or be secured by adhesive between two such webs. In a modification, four separate lengths A1 to A4 of materials which may be of different colours &c. are supplied to the rollers 54 of an inclined chain 41. The rollers 54 co-operate with the rollers 24 on a vertical chain 1 to draw out and feed forward the materials as looped stretches. The materials are supplied through tubular pivoted guides 111 which are rocked by springs and tappets 117 on a pattern drum to move the materials they guide into or out of the path of the rollers 41, so that the various materials may be supplied in regular succession or any other order. A " flicker " or casting off device comprising a thin blade 57 on a boss on a shaft 58 oscillated by gearing and camcontrolled mechanism removes the loops from the rollers 54. In other modifications described, " flickers " such as 57 are used at both sides of the apparatus. Two inclined chains may be used situated in the same plane with a central movable guide for the material. Two such devices may be used side by side to supply two lengths of materials drawn into loops and serving as wefts, a web of warp being fed between these to constitute a stuffing medium extending along the space between adjacent knitted chains which bind the weft together.
