Abstract

1,052,884. Laminates and laminating. CELENE S.p.A. May 28, 1963 [May 29, 1962], No. 21294/63. Heading B5N. [Also in Division F2] A tubular film 1 of plastic material is extruded from an annular die 3 of an extruder 2 and whilst advancing is inflated with air and covered with a reinforcement of yarn or thread 7 unwound from spools 5, 5<SP>1</SP> located on rotary annular platforms 6, 6<SP>1</SP>, this reinforcement being covered by a second tubular film extruded from an annular die 12 of an extruder 11. A hollow mandrel 8, Fig. 2 (not shown), is supported by the die 3 within the tubular film 1 at the location where the reinforcement 7 is applied and cooling liquid is circulated through the mandrel. A similar arrangement may be provided at the location of the annular die 12. The finished tube after prior flattening between rolls 22, Fig. 1 (not shown), is wound on a bobbin.
