Abstract

The support is for use when producing by moulding structures incorporating hollowed-out portions. It has protrusions each formed by an inflatable envelope (3), jointed to each other by a flexible wall (1) to the face of which they are fixed. Each protrusion can have its own inflating and deflating pipework, and the pressure inside them can be controlled simultaneously for all, or independently. The protrusions can form separate blocks, or extended parallel ribs. The flexible wall can itself be an inflatable structure acting as a mould support, with inflatable protrusions on the outside.
