Chopped glass fibre bundles are made into a random-orientated fibre mat by blowing them in a turbulent current of air. The fibres are also bonded into GRP with e.g. thermoplastics. Specifically glass fibres are fed by the hopper into a current of air in the feed tube leading to the chamber. The quantity of glass is decided by the process and it also has the appropriate content of powdered binder. The dry mix is fed to the bottom of the chamber, the top of which has a filter and plate moved by the cylinder. The dry mix is swirled round turbulently in the chamber. The bottom damper is opened, the top plate is dropped down, and the mix is pressed on the conveyor belt and its backing below. The sheet of material is conveyed to the heated band press and consolidated into an intermediate GRP sheet.

A method of compressing an uncured man-made vitreous fibre web , the web having two opposed major faces , wherein the method comprises the steps:passing the web along a path; andsubjecting the web to thickness compression by applying compression to the two major opposed faces of the web,whereincompression of each of said major faces of the web is applied by passing the path between converging continuous or discontinuous compression surfaces,whereinthe respective major face of the web that is being compressed is in contact with one of the converging compression surfaces,whereinsaid converging compression surface is inclined towards the path, and whereineach inclined converging compression surface applies an amount of compression to the major face of the web with which the respective inclined converging surface is in contact, wherein the amount of compression applied to at least one of the two opposing major faces of the web is adjustable.2. A method according to claim 1 , wherein each surface ...
