Abstract: 641,989. Extruding thermoplastic material. DURATUBE & WIRE, Ltd., and VEIT, J. Dec. 5, 1947, No. 32125. [Class 87 (ii)] Patterned thermoplastic strip material is made by disposing a stationary obstructing element in front of the die. The element obstructs but does not entirely interrupt the normal free flow of the hot thermoplastic material. The element, which may be a wire or a thin rod or bar, is arranged horizontally in front of, parallel to and spaced from the front surface of the die. Fig. 1 shows a wire or thin rod 1, fixed at its ends 2, engaging the underside of a hot plastic strip 3 issuing from an extrusion die 5 and forming transverse ribs 6 thereon. Fig. 2 (not shown) illustrates the effect of the wire 1 on an extruded strip having longitudinal ribs on its upper surface, the ribs being broken up into protuberances. Fig. 3 shows the appearance (like wickerwork) imparted to a strip having the section shown in Fig. 3A. In Fig. 4 a number of separate cords or threads 17 are extruded; the wire not only produces protuberances 18 thereon but unites the cords &c. to form a single strip. Figs. 5 and 6 (not shown) illustrate the result of so arranging the wire that it cuts the strips of Figs. 1 and 2 into two halves. Fig. 7 shows how a strip having longitudinal ribs 21 is cut into halves by the wire, each half having protuberances 22 formed from the ribs. Fig. 8 (not shown) is like Fig. 3, but the extruded strip has ribs on both sides and the wire cuts the strip into halves. Fig. 9 (not shown) is like Fig. 4, but the threads &c. are cut into halves. When the wire cuts a strip into halves, the halves stick together while still hot and soft but may be torn apart.
