Abstract: A vulcanizing mold (10) for a tire includes a frame (24), two lateral shells (26, 28), a plurality of segments (30), a lever (36), a pivot link with an axle (38) for linking the lever (36) to the segment (30), a pivot link with an axle (44) for linking the lever (36) to the driving shell (26), a slide ramp (46) for the axle (44) of the pivot link, the lever (36), the pivot link and the slide ramp (46) being arranged such that the axial displacement of the driving shell (26) with respect to the frame (24) causes a displacement of the axle (38) of the pivot link which is substantially exclusively radial with respect to the driving shell (26).

Abstract: The vulcanizing mold (10) for a tire comprises: a frame (24), two lateral shells (26, 28), a plurality of segments (30), coupling means (34) comprising a lever (36), means (37) for linking the lever (36) to the segment (30) which comprise a pivot link with an axle (38), means (43) for linking the lever (36) to the driving shell (26) which comprise a pivot link with an axle (44), guide means (45) for the axle (44) of the means (43) for linking the segment (30) to the driving shell (26), the coupling means (34) and the guide means (45) being arranged such that the axial displacement of the driving shell (26) with respect to the frame (24) causes a displacement of the axle (38) of the means (37) for linking the lever (36) to the segment (30) which is substantially exclusively radial with respect to the driving shell (26).

Abstract: A rotary hole punch (T) comprising a cylindrical head (10) with circular section, the free end (11) of which can be gripped by a means able to drive said hole punch rotationally, a cylindrical tube (20) of circular section, attached to the inner end (12) of the head (10), and ending in a cutting edge (21), characterized in that the head (10) of the hole punch includes at least one duct (13) making it possible to feed a fluid under pressure inside the tube (20) at the level of the inner end (12) of the head (10).
