The sliding carriage (5) moves between two end-stops along guide rails (3,4) of a basic body consisting of a hollow profiled rail (2). The sliding carriage is connected to the ends of a toothed belt (38) tensioned over a toothed deflection roller (56) and over a toothed roller (22) driven by a servomotor. The toothed deflection roller is adjustable in relation to the toothed drive roller by means of a tensioning device and is fixed in a set position. The toothed deflector roller is mounted in a holder (64) positioned with two long side walls (67,68) joined by a transverse end wall (83) end-side in the hollow interior of the basic body. The roller-holder is tensioned by a central straining screw (84) joining the end wall (83) with an end plate (61) of the basic body. In its tensioning position, the holder is fixed by a clamping screw (88). |
