A mold for molding a tire tread comprises a plurality of mold segments. Each of the plurality of mold segments includes an integer number of tread pitch repetitions. The plurality of mold segments are structured to be coupled to each other end-to-end so as to form the mold such that the mold includes an integer number of tread pitches. The mold also includes at least one mold end segment positioned on at least one end of the mold and has a mold end segment length shorter than a length of each of the plurality of mold segments.

A tire mold capable of improving the efficiency in mold production and tire production without compromising the aesthetic quality and performance of a tire after cure-molding. To that end, the tire mold has a hole that penetrates from the molding surface for molding a rubber article to the back surface, a core member that is disposed inside the hole and forms an air discharge flow channel annular in cross section extending along the extension direction of the hole between itself and the hole wall forming the hole, and an interlinking part for interlinking the hole wall and the core member.

A mechanism releases a plate from a recess in a tire mold part. The mechanism includes a bolt insertable into a hole in the tire mold part and extending from a first end at an outer surface of the tire mold part to a second end at a recess for a pocket plate in the tire mold part. The first end of the bolt has an axially extending projection allowing manipulation of the bolt about an axis within the hole. The projection is defined by two diametrically opposite curved surfaces interconnected by two diametrically opposite planar surfaces.

A pneumatic tire is provided with sipes, at least some of which have an open top end to the surface of the tread block. An intersection of the sipe with a surface that is geometrically congruent and parallel with the surface of the tread block and arranged a depth apart from the surface of the tread block into the tread block forms a curved line. A first sipe is shaped in such a way, that at all depths (d) within a range from the open top of the first sipe to a first transition depth, the curved line includes at least one deflection point having an inner corner that has a radius of curvature under 0.3 mm. A lamella plate for manufacturing the pneumatic tire, the tread band, or the tread block. Use of the lamella plate for manufacturing a tread block, a tread band, or a pneumatic tire.

Disclosed herein is a tire molding element. The tire molding element includes at least a molding surface for molding a plurality of ground contact elements of the tire tread, comprising: a ground contact surface which contacts a road surface, and a transverse side surface and a circumferential side surface connected to said ground contact surface; and a plurality of thin plates, comprising: a main body, provided in such a way as to cut a covering layer arranged in advance on an unvulcanized green tire.

A method for producing a mold segment of a vulcanizing mold for a pneumatic vehicle tire for forming the profiling of a tread, having a metallic base part (6) with a mold side with ribs (3) which form channels encircling or delimiting profile elements. A rib skeleton (8) consisting of ribs (8), the arrangement and the profile of which at least partially corresponds to the arrangement and the profile of ribs (3) forming channels, is milled from the base part (6), inserts (7) with peripheral frame parts (7b) are built up by means of an additive method, the inserts (7) being inserted into the rib skeleton (8) and the frame parts (7b) completing the ribs (8) of the rib skeleton (8) to form the ribs (3) forming the channels.
