Abstract
The invention is about a valve system to grip a sleeve over a mandrel in a press, in particular on how the gripper is brought toward and away from the mandrel and sleeve assembly. The gripper is disengaged from the sleeve, following first a straight path and then a helicoidal path, thanks to an ad-hoc slot machined on an axle. This allows to disengage the gripper and set it out of the way for handling the sleeve, with a single motor and a single instruction.
