Abstract

A gripping apparatus for gripping elongated workpieces comprises a housing, carrying two pivotable gripping jaws which are movable between opened and closed positions, as well as a guiding body, in which the housing is displaceably supported.A rod having a control element which is located between both gripping jaws and is displaceable between a position retracted into the gripping jaws and so as to spread them apart, and an opposite position, where the gripping jaws are converged.The control element engages the housing and, during a further movement in the retraction direction moves the housing.
