Abstract: A tread block arrangement is for a tire or for a tread band for a tire. The tread block arrangement includes a tread block having at least a first sipe delimited by a first sipe wall, a second sipe wall and a bottom of the sipe. The first sipe wall and the second sipe wall are arranged parallel to each other and define a width (w) of the sipe. At least the first sipe wall has at least one inclined section in which a width of a surface of the first sipe wall in a longitudinal direction of the sipe and the width of the sipe increases towards the bottom of the sipe.

Abstract: Embodiments of the invention include methods for reducing deformation of a sipe-molding member (10) arising during manufacturing operations, and sipe-molding members (10) comprising a sipe-forming portion (12) and a plurality of stiffening members (20) spaced along the sipe-forming portion. The sipe-forming portion (12) has a length extending in a lengthwise direction of the sipe-molding member (10), a height configured to extend into a depth of a molding cavity, and a thickness extending perpendicular to both the length and height. The sipe-molding member (10) is configured to form a sipe having a thickness commensurate with the thickness of the sipe-forming portion, a length formed by at least a portion of the length of the sipe-forming portion, and a depth formed by at least a portion of the height of the sipe-forming portion. Each of the plurality of stiffening members (20) extend outwardly from the thickness of the sipe-forming element. Further embodiments include methods of forming a molded tire tread.

Abstract: A tire mold or a tire mold segment can include an air compression cavity, which connects to multiple surface connection slots having dimensions between 10 and 300 microns, which can be suitable for selective removal of air in the mold. The air compression cavity, can be close to the outside ambient, allowing the air escaping the interior of the mold to be compressed, which can assist in preventing the rubber material from leaving the mold pattern surface.
