Abstract (en)
[origin: WO9700163A1] Solid elastomeric gel is produced in a continuous process using a twin screw extruder (10). Gel from the extruder (10) can be fed through a die (21) to form a length of the gel (20) with a uniform cross section and then cut to length to provide pieces of the gel (20) for use in a pad. Alternatively, gel from the extruder (10) may be injected into a chamber between a rigid base portion and a thermoplastic sheet to form that sheet and a surface of the layer of gel in the cavity against a surface in a cavity, thereby producing a pad including the layer of gel that has a precise predetermined peripheral shape corresponding to the surface in the cavity and is covered by the sheet which also has that peripheral shape and is wrinkle free.
