ABSTRACT:
A process for continuous production of shaped bodies of synthetic resin reinforced with axially parallel fibers wherein a plurality of continuous fibers are drawn through spaced apertures in a perforated guide plate and then through an alternating series of impregnating baths and shaping nozzles and finally through a hardening zone. The impregnating baths, shaping nozzles, and drying zone are disposed in a vertical arrangement, the shaped body withdrawn from one shaping nozzle is passed with a further group of fibers through the next resin impregnating bath and shaping nozzle, the impregnating resin on the surface of the shaped body is still liquid as it enters the next impregnating bath and all of the impregnating baths and the drying zone are maintained at the same temperature. The resulting fiber-reinforced shaped synthetic resin bodies are particularly suitable as electrical insulators which also exhibit good mechanical strength and which are especially useful in high voltage installations.
