Abstract
A device is disclosed for tensioning of a pulling element (1) of a printer and in particular of a matrix printer, for a back and forth motion of a part (5) or of a carriage includes a first deflection roller (11) and a second deflection roller (12). A wedge surface (15) is furnished, which upon increasing inclination (16) is slidable in a direction parallel to a frame surface (17) disposed perpendicular to the pulling direction (18) and which wedge is subjected to the force of a tension spring (22) such that the adjustable second deflection roller (12) serves the purpose of an increase of the tensioning force in the pulling element (1). In order to provide a substantially rigid system, which also takes the production stretching of a pulling element (1)--pulling cord--into consideration, it is disclosed to rotatably support the second deflection roller (12) with its roller bearings (24) in a lever (13), formed as a covered casing (23) and that an adjustable cam ( 25) resting at the wedge surface (15) is rotatably supported in the casing (23) and that the cam position can be fixed.
