Abstract
A process for producing a hollow plastics article, which comprises introducing a polymerizable composition in the hot state into a sealed hot mould, immediately setting the mould in motion by imparting to it a second movement of rotation about a second axis and a third movement of oscillation about a third axis which is perpendicular to the second, so that the composition is applied to the inner walls of the mould, and polymerizing it herein to form a hollow article. The improvement comprises setting the mould in motion by further imparting to it, simultaneously to the second and third movement, a first horizontal movement which has, in a horizontal plane, two components in two directions perpendicular to each other.
