Method for implementing an extrusion facility intended for the production of a profiled element, said extrusion facility comprising a roller which is supported rotatably by at least a first bearing, a tool module which comprises a die intended to interact with the roller so as to form an air gap allowing the profiled element to be shaped, and at least a first head module having a first extruder which is intended to supply the tool module with a first constituent material of the profiled element, said method being characterized in that it comprises: - an engagement step, during which the tool module is moved relative to the first head module and to the first bearing in a first direction referred to as the "engagement direction", in such a way as to bring said tool module into abutment against the first bearing and to subject said tool module to a preload force (F_Z) which is oriented in the engagement direction and counter to the first bearing, in such a way as to place said tool module relative to the roller in a configuration referred to as the "engagement configuration" which defines the desired air gap for producing the profiled element, - then a clamping step, during which, while said tool module is in its engagement configuration, prestressed against the first bearing by the preload force (F_Z), said tool module is clamped between the first head module having the first extruder and a second head module distinct from the first head module, by moving said first head module and the second head module towards one another, on either side of the tool module, in a second direction referred to as the "coupling direction" which is transverse to the engagement direction, preferably perpendicular to said engagement direction, in such a way as to place the first extruder in communication with the tool module, and by subjecting said first and second head modules (13, 23) to a clamping force (F_X) which is oriented in said coupling direction, in such a way as to hold the tool module by compression between the first and second head modules (13, 23). - an engagement step, during which the tool module is moved relative to the first head module and to the first bearing in a first direction referred to as the "engagement direction", in such a way as to bring said tool module into abutment against the first bearing and to subject said tool module to a preload force (F_Z) which is oriented in the engagement direction and counter to the first bearing, in such a way as to place said tool module relative to the roller in a configuration referred to as the "engagement configuration" which defines the desired air gap for producing the profiled element, - then a clamping step, during which, while said tool module is in its engagement configuration, prestressed against the first bearing by the preload force (F_Z), said tool module is clamped between the first head module having the first extruder and a second head module distinct from the first head module, by moving said first head module and the second head module towards one another, on either side of the tool module, in a second direction referred to as the "coupling direction" which is transverse to the engagement direction, preferably perpendicular to said engagement direction, in such a way as to place the first extruder in communication with the tool module, and by subjecting said first and second head modules (13, 23) to a clamping force (F_X) which is oriented in said coupling direction, in such a way as to hold the tool module by compression between the first and second head modules (13, 23).
