Placing of yarn groups on conveyor hooks for weft feeding of warp knitting machine involves laying successive traverses at an angle over each other

摘要

Groups (B) of yarns are placed by a traversing guide (2) over hooks on two conveyors (3, 4) in preparation for feeding as weft to a warp knitting machine. Yarns in successive traverses cross at an angle ( psi ) by displacing the guide in successive positions (2a, 2b) by less than the width of the yarn group (B), The displacement reduction is smaller than 50% of the width of the yarn group (B). Independent claims are also included for the following: (a) a knitted fabric with longitudinal and multi-axial reinforcement prepared by using this method with two groups of diagonally laid yarns making angles of 55 deg and 125 deg with the length direction; (b) a similar fabric with three groups of diagonal yarns making angles of 40 deg , 90 deg , 140 deg ; (c) plant for laying the yarns according to this pattern.
