Abstract

343,434. Delivering rubber cords, tubes, &c. from extrusion machines. SOC. ITALIANA PIRELLI, and PESTALOZZA U., 21, Via Fabio Filzi, Milan, Italy. Nov. 8, 1929, No. 34217. [Class 87 (ii).] Threads, cords, tubes, strips, or other continuous lengths of rubber or other plastic material are conveyed from the extrusion, rolling or other apparatus in which they have been shaped, by a body of liquid moving faster than the issuing strips &c. in order to effect a tractional effort thereon. Tubes 11 may be extruded through heated nozzles 13 and gas may be supplied through an orifice 14 in the core 12 in order to render the tube buoyant and to prevent collapse of the tube walls. The liquid conveyer may be a stream of water, or glycerin or other liquid of required specific gravity and of non-injurious character. The liquid may be circulated in a closed system by a pump 5 and pipes 6, 7. The conveyer trough is provided with a deflector 8 and a bridge 9. Rollers at the end of the trough pass the strips &c. on to winding mechanism. Two examples of the working of the process, with numerical data, are given in the Specification. Specifications 193,451, 208,235, 284,608, 292,964, and 330,520, [all in Class 70, Indiarubber &c.], are referred to.
