Abstract

A gripper assembly with gripper fingers (2) which are mounted so that they can be guided and moved radially inward and outward relative to the main body of the assembly. The gripper fingers (2) are biased radially inward by springs. Fitted in the main body (1) is a finger-opening device (20) with a conical body (21) which moves all of the fingers (2) radially outward together against the action of the springs. If the finger-opening device (20) is then retracted, at least some of the fingers (2) come to rest against the edge of the disc-shaped article. If the device (20) is retracted further, the remaining fingers also come to rest, under the action of their associated springs, against the edge of the disc-shaped article. The conical body (21) in the finger-opening device (20) acts on the fingers (2) via guiding elements (12) fitted inside the main body and connected to the fingers (2) by guiding rods (8).
