ABSTRACT MULTIPLE STITCH-THROUGH FABRICS A novel stitch-bonded type fabric is produced in a stitch-through type machine such as a Malimo machine using the method and apparatus of the invention, which fabric comprises: (a) a flexible substrate in the form of two or more superimposed filling layers each consisting of one or more parallel continuous textile elements extending obliquely across the width of the fabric; and (b) a single system of knitting thread wales extending along the length of the fabric, each wale comprising a multiplicity of looped stitch courses which engage and secure the superimposed filling layers against relative displacement by loops of knitting thread on the rear surface of the fabric and by loops of the knitting thread courses on the front surface of the fabric. The method and apparatus involve delivering the filling layers obliquely between and in engagement with two parallel endless rows of hooked leaded units by a cor- responding number of comb-like carriages each adapted. for synchronous reciprocating movement and each thereby independently conveying a filling layer back and forth between and in a direction perpendicular to the rows of leaded units which are concurrently moving in a direction. substantially parallel to the direction of delivery of the substrate to the stitch-through zone of the machine.
