Abstract: Process for additive manufacturing of at least one part. At least one layer of powder is deposited on a working surface using a layering device for distributing the powder mobile in translation along the surface and at least partly fusing the layer deposited using a beam of energy. The depositing and fusing steps are repeated in order to form the part by stacking of fused layers. The distribution component of the layering device is mobile in a direction substantially parallel to the direction of the length of each fused layer of the part. The depositing and fusing steps are repeated in order to form the part so that the length of the part extends along a direction substantially parallel to the stacking direction of the fused layers and so that the head of the part is oriented substantially perpendicular to the working surface.

Abstract: A mold for vulcanizing and molding a tire is provided herein. The tire includes a tread delimited by two sidewalls, the mold including a ring for molding the tread of the tire and two shells for molding the sidewalls. The mold includes an annular groove extending in a recessed manner in one of the shells and an insert housed in the groove, this insert having tire marking elements and being formed from a plurality of insert parts that are positioned one after another in the annular groove.

Abstract: A mold element for vulcanizing all or part of a tire tread intended to accept studs for driving on ice. The mold element comprises a molding surface able to mold all or part of the tread surface of this tread. The mold element comprises an insert added into the mold element. The insert comprises an insert body intended to be fixed into the mold element, a rod intended for molding into the tread a cavity that is capable of accepting a stud, this rod being fixed removably to the insert body, marking means able to mold a pattern on the tread near the stud. The marking means are fixed removably to the insert body by fixing means.

Abstract: The invention relates to a tire curing mold comprising at least one lining element for molding the tread of said tire, said lining element comprising at least one bead for molding a groove in the tread. The curing mold comprises at least one insert forming a portion of the bead, said insert partially or completely delimiting a slot extending into the depth of the bead. The slot is oriented substantially perpendicularly to the bead. The slot is configured in order to mold a flexible wall of reduced thickness made as one piece with at least one wall of the groove molded by the bead.
