Abstract

A gripper for holding preforms or containers in their neck region having two pivotable gripper arms held in a base position under spring tension such that their gripping ends jointly enclose and hold the neck region. They are pivotable out of the base position jointly in one direction if they come into contact with an obstacle. In the base position, a main gripper arm is clamped via a spring with the gripper base, which pulls the main arm into contact with the other secondary gripper arm. The main and secondary arms are each mounted in a respective joint. The joint of the secondary arm is closer to its gripping end than the joint of the main arm is to its gripping end. The arms press against one another in the closed position at least in two regions, one above the joint of the secondary arm and the other below it.
