Abstract
A roller for compressing protective sheeting of polymer material around a pipeline rotates about a given or designated axis of rotation and has a shaft; and a first tubular portion which extends about the shaft and varies in elasticity along the given or designated axis of rotation; more specifically, the first tubular portion is of greater elasticity at the ends of the roller than at the center of the roller.
