Abstract

A core mask is mounted on a rear plate which is designed to establish a vacuum or a pressure for holding the core or cores in the mask. A unit including a mask and rear plate is stored in a magazine near a core setting system. The unit is transferred from the magazine to the core setting system, where it is positioned and fastened so that it can be released while at the same time a fluid connection is established between the unit and the core setting system. The unit is removed after use from the core setting system by release of a lock and the unit is returned to the magazine.
