Abstract

A tension-adjusting device for a driving belt comprising a tension roller and having an engagement arrangement provided between a support of the tension roller and a machine frame for enabling stepwise swiveling movement about a partially disengaged mounting bolt. The axis of swivel is radially displaced from the rolling axis of the tension roller. The engagement arrangement comprises a projection formed on the support radially displaced from the axis of swivel and a plurality of depressions formed in the machine frame and arranged at regular intervals along an arc defined by the path of travel of the projection during swiveling, whereby the projection is engageable with each depression, thereby defining a corresponding step in a range of adjustment of the tension of the driving belt.
