ABSTRACT:
A band-tensioning device is disclosed which includes an operating lever rotationally fast with an eccentric which is pivotable about a fixed axis. An angle lever is provided which is freely pivotable about the eccentric, and urgeable to rotate therewith by means of the operating lever. A lower portion of the angle lever has an abutment surface which can cooperate with the friction surface of a rotatable tensioning wheel to force a band to be tensioned against the rotating wheel. The pivoting of the eccentric relative to the angle lever displaces it transversely to the abutment surface, so that the surfaces become separated and thus disengaged without having to overcome the high wedging forces associated with the tensioned band between the surfaces. The levers may be coupled by means other than the eccentric, e.g., via an articulated lever, provided the angle lever is selectively movable pivotally or transversely to the abutment surface.
