The fabric may be omitted from the process, thus producing a stubby surfaced resilient rubber layer.  A stripping agent, e.g. a silicone oil such as methylpolysiloxane, which is tacky at ambient temperatures and loses its adhesiveness after heating may be interposed between the perforated belt and the carrier belt whereby the said belts stick together as the rubber is forced into the perforations but may be easily stripped after the rubber is cured.  The perforated and carrier belts may be made of polyethylene terephthalate or stainless steel.  The rubber may be natural or synthetic, e.g. a polyurethane made from poly(ethylene/propylene adipate) and toluene 2,4 di-isocyanate. The taxtile fabric may be nylon.
