  • Publication number: 20230226855
    Abstract: A lamella plate for forming a sipe to a tire includes a first surface and an opposite second surface. The first surface has a first primary plate indentation and a first primary plate protrusion, and the second surface has a second primary plate protrusion opposite to the first primary plate indentation and a second primary plate indentation opposite to the first primary plate protrusion. The first surface defines a first primary lamella plate surface having a planar or a curved surface, from which the first primary plate protrusion protrudes and into which the first primary plate indentation descends. The second surface defines a second primary lamella plate surface having a planar surface or a curved surface, from which the second primary plate protrusion protrudes and into which the second primary plate indentation descends. A tire includes a primary first sipe producible in a molding process using the lamella plate.

  • Patent number: 11554613
    Abstract: 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.

  • Patent number: 11110754
    Abstract: A tread block arrangement suitable for a tire or for a tread band for a tire. The tread block arrangement comprises a tread block that limits a first primary sipe. The first primary sipe comprises at least a first deep part and a second deep part separated from the first deep part by a first shallow part. A depth of the first deep part is at least three times a depth of the first shallow part and a depth of the second deep part is at least three times the depth of the first shallow part. The first deep part is limited in a longitudinal direction of the first primary sipe by a primary first end wall and a secondary first end wall such that a first angle between the primary first end wall and the secondary first end wall is from 1 degree to 30 degrees.

  • Patent number: 9764601
    Abstract: A vehicle tire (1), including a tread (2) which intended for rolling contact with a foundation, the tread 82) being formed with a tread pattern (20) which includes circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the foundation and the tire (1). The circumferential groove (25) has its wall (251) formed with a flow deflector (259) reducing a width of the circumferential groove (25), commencing from the wall (251) of the circumferential groove (25), bypassing a reduced-width portion (250) of the circumferential groove (25), and continuing arcuately into the transverse groove (26) so as to turn into a wall (261) of the transverse groove (26).
