Abstract
815,423. Making pipes. GANAHL, C. DE. Sept. 3, 1957 [Oct. 12, 1956], No. 27724/57. Class 99(2). The apparatus is identical with that described in Specification 750,768 but the glass fibres are immersed in the liquid plastic while still at a temperature above 200‹F. and preferably in the range 250‹F. to 450‹F. Specification 687,552 also is referred to.
