ABSTRACT:
A length measuring device is disclosed in which a bending rigid scale carrier is fastened to a slide piece of a machine tool at both ends by means of respective clamping shoes. A flexible measuring band is mounted on the surface of the scale carrier by means of an adhesive layer so as to be slightly shiftable in the measuring direction. The measuring band defines a graduation scanned by a scanning unit connected to the bed of the machine tool. The two ends of the measuring band are fastened by means of welding points to the ends of the scale carrier. In order to provide error correction, the end zone of the scale carrier is constructed as a stretching element formed via a joint as an integral part of the scale carrier. An adjusting screw engages directly on the scale carrier in order to adjust the longitudinal position of the stretching element in order to alter the effective length of the scale carrier and thereby adjust stretching forces applied to the measuring band to provide the desired error correction.
