<p>The tool grip has several gripping arms, which are at a relative distance and project from a holder. The arms are moved towards each other by a drive, and are formed as leaf springs (2), rigidly fastened to one side of the holder (1). The drive units have two pressure elements (10), which are longitudinally adjustably fastened to the holder. The leaf springs are supported on the pressure elements. Dependent upon the length of the adjustment, the elements apply a sideward directed force to each leaf spring. The elements are formed by pressure rollers, held on a rigid transverse yoke (9) on the holder, with jacket surfaces engaging the leaf springs.</p> |
