Centrifugal casting device for producing pipes from composite material

摘要

The invention relates to a centrifugal casting device for producing pipes from composite material with a centrifugal mould and an operating arm which can reach into the centrifugal mould and can be withdrawn from it. The operating arm has, starting at its front end, a pressing roll section for smoothing the interior of a pipe to be formed, a first feed section for liquid resin, a second feed section for liquid resin, a feed section for disperse fibre material, a third feed section for liquid resin, a sand-smoothing section for smoothing sand which has been added to the liquid resins, a sand feed section and a roving feed section. According to the invention, the operating arm has various functions and, by reaching into and withdrawing from the rotational mould one or more times, it is possible economically to mould various types of pipes from composite material.
