This invention relates to a broadening and stretching roller for flexible webs such as webs of textile, paper or plastics material. An outer shell of the roller is mounted on a shaft by means of bearings which in turn are secured between the shell and the shaft by mounting means comprising end cups, tubular section members, and ring means. All of these bearing mounting means are made of plastics material such as duro-plastics or thermo-plastics. Corrosion resistant sleeves of metal and/or of plastics material are secured to the end of the shaft in such position as to be partially overlapped by said end cups.
