Abstract
Warp knit fabrics, especially sewn-knitted fabrics, are produced by a method and apparatus whch results in single and multiple layer sloping fabrics having oblique and diagonal endless filling threads with respect to the boundary of the fabrics. Spaced-apart chain conveyors transport a plurality of filling-thread sections, each of which contains a plurality of endless filling threads, to a stitch-forming site. The plurality of filling-thread sections are held between and transported by the conveyors by a plurality of hooks in the conveyors. Filling thread sections are laid onto the hooks by at least one filling laying device having a guide means for laying the filling thread sections onto the hooks. The filling laying device, guided by a pair of guide rods adjustably positioned obliquely and diagonally with respect to the direction of transportation of the chain conveyors, moves back and forth between the chain conveyors obliquely and diagonally with respect to the direction of transportation of the chain conveyors so that the filling thread sections are laid onto the hooks at an oblique and diagonal angle to the boundary of the fabric. Depending on the number of filling laying dev…
