Abstract

879,404. Compression-moulding machines. REGIE NATIONALE DES USINES RENAULT. Aug. 5, 1959 [Aug. 14, 1958], No. 26822/59. Class 87(2). Fibrous reinforcement 1, in sheet form, is laid in the cavity of a mould 2 and liquid resin 10 is spread on it. A plunger 3 carries a cutter 4 surrounded by a resilient gasket 6 which presses the reinforcement 1 on the portion 8 of the mould before the interaction between the cutter 4.and a counterblade 7 takes place, so preventing the reinforcement from being rammed in the bottom of the cavity. At the end of the stroke, determined by an adjustable stop 5, the gasket is flattened and recesses 9 therein are therefore closed, rendering the mould fluid-tight. In the closing movement of the punch the recesses 9 alter in size and shape, due to the resilience of the gasket, in proportion to the distance between the punch and the die, resulting in even distribution of the liquid resin due to controlled venting of the air pressure. The cutter trims the excess overlapping edge of the sheet 1.
