A method for closing a facility () for extrusion of a profiled element () comprising a roller () supported by a bearing (), a tool module () intended to interact with the roller () so as to form an air gap () for shaping the profiled element (), and at least a first head module () having a first extruder () comprises an engagement step (s), during which the tool module () is urged against the first bearing () by a preload force (F_Z), in an engagement direction (Z), then a clamping step (s) during which the tool module () is clamped between the first head module () and a second head module (), on either side of the tool module (), and by subjecting them to a clamping force (F_X), in a coupling direction (X) which is transverse to the engagement direction (Z).

A powder-based additive manufacturing installation () comprises a powder layering device () that can be displaced along a path linking a start zone (A) and an end zone (B). The layering device () comprises powder deposition means () for depositing powder in a powder deposition zone (D) situated between the start zone (A) and the end zone (B). The installation comprises a cleaning device () situated on the path of the layering device (). The cleaning device () comprises a blowing device () configured to blow a gas flow onto at least one surface of the powder deposition means ().

A tire vulcanizing system () is provided that optimizes the service life of guidance means and preserves the thermal stability of the vulcanization.

Maximizing the duration of guidance means in tire vulcanization systems without disturbing thermal stability

A method is provided for dry cleaning a plate used in an additive manufacturing process involving a powder. According to the method, unconsolidated powder is separated from a plate and collected by imposing vibrations on the plate and causing the plate to experience shocks.

Method for the dry-cleaning of additive manufacturing plates

An installation is provided for cleaning a plate used in an additive manufacturing process performed using a powder. The installation includes an entry lock, an exit lock, a dry cleaner, a wet cleaner, and a conveyor system. The entry lock is structured to accept into the installation a plate that is to be cleaned. The exit lock is structured to allow the plate to be extracted from the installation after cleaning. The dry cleaner is structured to clean the plate using vibrations and shocks in a first confinement enclosure. The wet cleaner is structured to clean the plate using at least one liquid in a second confinement enclosure. The conveyor system is structured to transport the plate between the dry cleaner, the wet cleaner, and the exit lock.

Unit for cleaning additive manufacturing plates

A device is provided for dry cleaning a plate used in an additive manufacturing process that involves powder. The device includes a confinement enclosure, a loader, and a dry-cleaning station. The confinement enclosure includes an entry lock through which a plate to be cleaned enters. The loader is located within the confinement enclosure and is structured to receive and transport the plate. The dry-cleaning station is located within the confinement enclosure and is structured to dry clean the plate. The dry-cleaning station includes a vibration device, which imposes vibrations on the plate, and a shock device, which causes the plate to experience shocks.
