ABSTRACT:
A completely self-contained apparatus and associated technique for the manufacture of large fiberglass structures. In a preferred embodiment, the system is designed to manufacture large fiberglass storage tanks for liquids, and is self-contained from the point of view that the machine is capable of performing all manufacturing steps without any auxiliary equipment and may be set up virtually anywhere that can provide a source of electricity and air. The main components of the machine include an operator's carriage which is cantilevered from a rear frame so as to enable same to be inserted into the open end of a large, substantially cylindrical revolving mold having a closed, substantially hemispherical end portion. The carriage includes an overhead canopy for the protection of the operator, as well as fresh air intake and exhaust fans to provide adequate ventilation for the operator. A raw material applicator is positioned in the forward portion of the carriage and is designed to apply the appropriate proportions of chopped fiberglass roving, resin and catalyst to the inner surface of the mold as the carriage reciprocates therein.
