Abstract
Abstract Apparatus for producing stitch bonded fabric and having needles which penetrate a fleece and receives threads which are controlled by thread guides and also including wires which enter but do not completely penetrate the fleece whereby a loop of fibers are formed around a hook of the needle and retained thereby. The threads lock the interengaged stitch loops and means are provided to permit a thread to be passed over the hook formation of the needle to form a tricot-stitch seam to the fleece.

An apparatus for producing a stitched bonded fabric from a fleece, said apparatus comprising a frame, a series of needles mounted in a spaced relation on said frame in a position to penetrate the fleece, a hook formation at the end of each needle, the hook formation being adapted to gather loops of fiber from the fleece upon withdrawal of the needle from the fleece, a corresponding number of thread guides mounted in the same plane as that of the needles and being reciprocally movable transversely on said frame to place threads on the hook formation at the end of each of said needles after penetrating said fleece, a rod positioned in each of said needles and being adapted to be moved partially through said fleece independently of said needles for mating engagement with said hook formations, a retention bar located below the level of the needles, and a series of support pins mounted on said frame and having their free ends cranked and positioned behind said retention bar to allow a thread on transverse movement of one of said thread guides to slide freely over the hook formation of one needle to the adjacent needle, whereby tricot stitches are formed and are locked into the fabric.
