    Abstract: An annular mold having a molding surface for forming a tread pattern of a tire is divided, at least in the peripheral direction, into plural pieces. The plural pieces are disposed adjacent to one another via adjacent surfaces, which are peripheral direction division surfaces, so as to form the annular mold. Substantially an entire molding-surface-side side edge portion of each adjacent surface of the piece is cut-out at a narrow width such that a gap for air venting is formed. Thus, at a low cost, a mold for molding a tire is provided in which there is no spewing, and air can always be reliably vented without a need for applying a vacuum.

    Abstract translation: 具有用于形成轮胎的胎面花纹的成形面的环状模具至少在周向被分割成多个片。 多个片通过作为周向分割面的相邻面相邻配置，形成环状的模具。 基本上，片的每个相邻表面的整个成型表面侧侧边缘部分以窄的宽度被切出，使得形成用于排气的间隙。 因此，以低成本形成轮胎成形用模具，其中没有喷射，并且空气总是可靠地排出而不需要施加真空。

    Abstract: A device for making a mold for molding at least a portion of a tread of a re using a countermold and a pourable, solidifiable material. Molding elements are transferred from the countermold and imbedded in the tire tread mold in protruding fashion by placing each molding element in a housing of the countermold before the actual molding of the tire tread mold and in such a manner as to permit easy transfer from the countermold to the tire tread mold.

    Abstract: A tire tread with elastomeric ground engaging elements having an incision is described. The invention is characterized by at least one of the elements having an incision extending from the tread surface towards the interior of the elastomeric material. The incision splits into at least two incision portions in the interior of the elastomeric material below the tread surface. The incision portions extend away from the tread surface and diverge apart from each other over at least part of their depth.

    Abstract: The tire-forming matrix has elongated zigzag ribs which are spaced apart to provide grooves for receiving and centering metal traction-augmenting coils. The sides of the ribs have peaks and valleys and peaks of a rib on one side of a received coil are disposed opposite the valleys of the rib on the other side of the coil, and sipe-forming strips are caused to project transversely from each valley, which strips aid the peaks in centering the wire coil. When the tire tread is molded the valleys at the sides of the matrix ribs provide a row of triangular rubber blocks on each side of each rider strip which project beyond the sides of the coil, and the sipe strips are positioned to break up these rubber blocks and provide more movement on the tire tread.
