ROLLER AND METHOD FOR COMPRESSING PROTECTIVE SHEETING OF POLYMER MATERIAL AROUND A PIPELINE

摘要

A roller (10) for compressing protective sheeting (9) of polymer material around a pipeline (1) rotates about a given axis of rotation (A2) and has a shaft (13); and a first tubular portion (14) which extends about the shaft (13) and varies in elasticity along the given axis of rotation (A2); more specifically, the first tubular portion (14) is of greater elasticity at the ends of the roller than at the centre of the roller (10).
