ABSTRACT:
An apparatus for the continuous fabrication of fiber reinforced plastic profile members or sections by impregnating fibrous mats with a settable liquid plastic reaction mixture in a continuous impregnation device. Arranged after the impregnation device is a transport- and forming device for drawing-through, shaping and hardening the impregnated fibrous mats. The continuous impregnation device embodies two superimposed contact- and guide platesarranged in spaced relationship from one another, these plates conjointly forming a continuously tapering inlet zone followed by an outlet zone and at both sides of the plates two edge guiding zones communicating with the free atmosphere, the edge guiding zones serving for the guiding of the side or marginal edges of the throughpassing fibrous mats. One of the contact plates is provided with an impregnation recess between the inlet zone, outlet zone and the lateral edge guide zones, this impregnation recess being positionally oriented transversely with respect to the direction of throughpassage of the fibrous mats and being connected at delivery lines or conduits for the liquid plastic reaction mixture which is at excess pressure.
