Abstract

Non-woven fabric made by extrusion of a plasticised material through a pair of die outlets with boundary line orifices which coincide and separate depending upon relative reciprocating or rotary motions imparted to the two die plates. For mfr. of sheet fabrics, die plates are pref. a pair of straight plates with semicircular openings along opposing edges, and tubular fabrics or stockings are made by a pair of concentric annular die plates. Pref. the relative motions or rhythms of the two dies is adjustable and programmable to produce various weave patterns for specific decorative or elastic effects. Adaptable for mfr. of garment edging, straps, braid, furniture fabrics, shopping bags, multiple packs, socks etc., with a wide variety of structures.
