Elongate products are moulded in a die (27, 28; 47) from fibre reinforced plastics by drawing a bundle of tows (23) through a bath (16) of resin (17) and between two portions of an open die (27, 28; 47), which is closed under high pressure are heated to cure the resin. The die is opened, and the product is then partly withdrawn lengthwise, to draw further wetted tows (23) between the die portions, and the die is again closed, clamping the tail end of the already cured product which still projects into the die space, or clamping blocks (41) at its downstream end. Cold clamping blocks (24) also clamp the tows (23) at the die upstream end. The products are subsequently severed externally of the die by cutter wheels (44). |
