Abstract
A method of producing a rubber-based covering comprising at least one layer formed from fragmented cohesible material comprises the steps of forming a substantially continuous bed of the fragmented cohesible material and subjecting the material of the bed to a compacting step so as to form a sheet material as a result of the cohesion of the material. The compaction step is performed with a substantial absence of stretching stresses on the fragmented material.
