Abstract
1,059,346. Extruding polypropylene tubes and films. B.X. PLASTICS Ltd. Nov. 18, 1963 [Dec. 1, 1962 (2)], Nos. 45575/62 and 45576/62. Headings B5A and B5B. Tubing of isotactic polypropylene 2 is extruded downwardly over a former 13 comprised of at least two separate polytetrafluor. ethylene discs situated within a tubular sleeve 6 below the surface of quenching water 6 which is drawn down through the sleeve 6 by suction pump 8, to quench the tubing 2 within the sleeve 6, at such a rate as to produce the desired crystallite structure in the material, yet avoid the cooling water boiling at the entrance of the sleeve 6. Air is passed by pipes 14, 16 through the tubing during extrusion to prevent it collapsing. After flattening by rollers 17 the tube may be blown into a film.
