ABSTRACT: Gripper having gripper arms supported in rotatable sliding guides. A gripper having at least two gripper arms (1,3) which are arranged mirror-symmetrically around a centre line (5) and a first end (7, 9) of each of which follows approximately a straight line (19) which is per- pendicular to the centre line (5), while the second end (21, 23) is displaceable along a circular track (33, 35). A gripper arm (1, 3) is supported between its first (7, 9) and second ends (21, 23) in a rotatable sliding guide (41, 43) which occupies a fixed position with respect to the centre (29, 31) of the respective circular track (33, 35). The dimensions of the gripper mechanism described are such that a minimum tolerance of the position of the first ends (7, 9) of the gripper arms parallel to the centre line (5) is obtained. The gripper requires a considerably reduced calculation capability from the processor to be used for positioning the gripper arms (1, 3).
