Support for cutting shoe materials by jet - has layer of perforated impermeable material and permeable self sealing layer

摘要

The equipment supports a workpiece to be cut by high speed fluid jet, particularly shoe-making material. One or more perforated supporting layers (4) of material are impermeable to the jet, and one or more layers of continuous material (14) are permeable to it. This layer contains self-sealing or self-repairing material for the cut made in it by the jet. It can be covered by a layer of solid permeable material, and can also have a layer of such material underneath. There can also be one or more layers of foam material, thick and dense enough to reduce the energy of the jet passing through it.
