Extrusion facility with underground transfer of the tool module

An extrusion facility intended to produce a profiled element, the extrusion facility comprising:

• at least one first head module which bears at least one first extruder intended to supply a constituent material of the profiled element;
• a core site configured to receive a tool module in order to enable connection of the at least one first extruder to the tool module in order to shape the profiled element,
• wherein the core site is located at a working level, which is provided with a floor on which an operator can move about to access the core site which is located above the floor;
• and
• an underground-transfer device which makes it possible to convey the tool module to the core site and/or, respectively, to remove the tool module from the core site, the underground-transfer device comprising at least one first lift cage which is designed to move the tool module through the floor from, or respectively to, a basement level, which is located below the floor of the working level.
