Abstract

The invention relates to processes and devices for producing curved pipes from a curable material containing, if appropriate, reinforcing inserts and/or fillers. In said processes and devices the material is moulded by centrifugal casting in a cylindrical mould which is rotatable about a horizontal axis, deformable in a curved manner and made of elastically deformable material. After completion of the rotation the mould containing the still-uncured pipe is deformed in a curved manner and the curved pipe is cured and removed from the mould. Before the mould is deformed in a curved manner, a flexible film bellows can be introduced into the pipe produced and be inflated with compressed gas to prevent undesired deformation of the pipe during the curved deformation. The mould can have a cavity located between the inner wall and outer wall, into which cavity liquid can be introduced during the centrifugal casting to produce a uniform curvature.
