Abstract

621,796. Moulding sheets of thermoplastic material. SOC. p. A. LAVORAZIONE MATERIE PLASTICHE. May 2; 1946, No. 13324. Convention date, July 22, 1942. [Class 87 (ii)] Sheets of thermoplastic material having ribs 2 - 4 and/or grooves are formed by extruding, through a die having ribs &c, a tube which is cut along a generatrix 5 on issuing from the die and flattened before hardening. Specification 634,071 is referred to
