Beschreibung
Zusammenfassung:	1,146,276. Moulding plastics material. JOHNS-MANVILLE CORP. 9 Aug., 1966 [8 Sept., 1965], No. 35562/66. Heading B5A. [Also in Division D1] A mass 2 of fibre, e.g. glass fibre, impregnated with an uncured resinous binder is pulled through freely mounted and heated rollers 4, 6 which partially cure the binder, and the compressed mass is then pulled between heated platens 18, 20 which finally shape the mass to a density of between 0.5 to 8 pounds per cubic foot and cure the binder. Rollers 40, 42 attached to the platens compress the material before it passes between the platens. The cured product is pulled through the apparatus by opposed endless belts on rollers 58, 60 and 72, 74. In a modified apparatus the material is shaped by rollers to a T-shaped cross-section before passing between heated platens, and a fixed core of T- section is located between the platens to produce an article of hollow T-section.
