ABSTRACT:
Rolls having an elasticity on their outer periphery are used in corrugated fibreboard producing and processing machines. Tubes or tubular sheet adapted to be inflated with gas, elastic cords or strings, elastic tubular sheets, or tubular sheets with air bubbles thereon or therein are used to at least partially cover the outer surface of the rolls, thus giving the rolls an elasticity.
