Abstract

Making the surfaces of unvulcanised sheet rubber stock non adhesive by dusting the surface with a flour made of ground rubber instead of the usual talc or stearate powders. The rubber flour prevents stacked or overlaid sheet from sticking firmly together, yet is fully compatible if overlaid surfaces are subsequently vulcanised. Esp. useful for storaging, transporting, and laying up slabs of thin perforated sheet stock for building up vehicle tyre side walls which initially allow trapped air to exhaust during tyre fabrication.
