Abstract
A device for producing an opening or cavity in the side of a ceramic product during product molding in a mould with a molding cavity delimited by a molding surface which has a window, comprising a deformable punch, joined on the window, designed to project into or retract from the molding cavity, with the ability to vary its rigidity. The device comprises punch shape variation differential constriction means and actuator means for punch deformation, which together produce a controlled anisotropic punch deformation, which makes the punch project into the molding cavity.
