ABSTRACT:
A tension roller with a supporting member, pivoted on a pivot stud against the force of a tension spring, and rotatably supported in a roller sleeve by a bearing. The supporting member has a cylindrical interior space, limited by side walls, containing the tension spring. The side walls have bores for the pivot studs and recesses for formation of the stopping faces, against which the free ends of the tension spring abut in order to limit the angle of rotation of the tension roller. The member is made of synthetic material, using injection molding techniques. In order to produce this supporting member in an economical manner, additional recesses permitting insertion of a forming tool consisting of two halves are provided in the side walls of the member.
