Abstract

The process produces insulating jacket for e.g. water pipes and of preformed thermo-setting material, individual pre-curved jackets being obtained by rolling completed sheets onto mandrels for cutting in the axial sense. A conveyor belt feeds a trains of mould boards beneath successive posts where a gel layer is deposited, the gel is polymerized, a resin layer is deposited, glass fibre reinforcement is spread and where finally the fibres are embedded as air bubbles are eliminated. In a sec. phase the boards are separated by cutting and wound individually onto mandrels for resin polymerization subsequent to cutting into jackets. A cellulose based film may be used to line the conveyor belt with the boards connected by adhesive strips, the film serving to facilitate sepn. of the boards and being fed from a reel.
