The grip (1) has two pneumatically operated grip arms. One of this forms a master grip arm (2) to position the other arm (3), the slave arm, relative to the workpiece, giving increased leverage on the workpiece. Each arm may be on a turning axis (S), dividing each grip arm into two lever arms, one to grip the workpiece and the other operated by a pneumatic cylinder (9). |
