ABSTRACT:
A method of making a resin panel in which a carrier film receives thereon a layer of thermosetting resin and glass fibers are placed on the resin layer. This composite is inverted and passed between a roller and a section of a moving belt, the belt being of a material impermeable to the resin. The resin layer with glass fibers therein is passed through a heating zone to cure the resin while on the belt. After the resin is cured it may be separated from the belt by bending the belt away from the resin.
The machine carries out the above method employing a belt of stainless steel or the like which extends over a pair of rolls to provide a conveyor for the formed resin layer. The machine has a pair of rolls for forming the resin-glass composite. One of these rolls serves to invert the layers and serves also to press the layers against the belt. Heaters are provided to heat the formed resin to cure it while on the belt. One of the rolls which rotate the belt is effective to bend the belt to separate the cured resin layer therefrom.
