摘要 |
A pultrusion die(10) for shaping and consolidating the resin-impregnated fibers has a cross-section which is periodically enlarged and reduced as the fibers are pulled through. The frequency of the oscillating cross-section is NOTGREATER 1kHz, preferably NOTGREATER 100Hz. An Independent claim is made for a pultrusion plant with a die(10), the die having a constantly tapering cross-section and comprising two opposing parts, one of which(12) is oscillated by a drive unit(14,15) producing a transverse movement(150), e.g. a parallel or swivelling movement perpendicular to the drawing direction, the point of swivelling being at the narrower, outlet side of the die. |
