摘要： A tire includes a plurality of tread blocks disposed circumferentially around the tire. At least one sipe is formed into at least one of the tread blocks and is defined by first and second confronting sidewalls. The sipe has a cross-sectional profile in a plane generally perpendicular to the top surface of the tread block, which profile has a generally arcuate central portion and first and second ends separated by the central portion. The sidewalls are spaced apart at least one first width at the central portion of the sipe, and are spaced apart at least one second width at the ends, wherein the second width is greater than the first width. In one embodiment, the sipe has a cross-sectional profile having a stepped configuration.

摘要： The present invention provides for an improved device for molding keyhole sipes larger in size, i.e. sipes having a wider passage, than currently being formed in treads that will avoid damaging the tread during formation and removal thereof from a mold. The device includes an elongated deformable body member having a blade extending in a direction away therefrom and substantially along the length thereof. The body member also includes a stiffening member securely fixed in position therein that extends substantially the length thereof. The stiffening member provides a desired rigidity to the deformable body member, thereby limiting flexion along its length under the stress of a rubber formulation when the mold is closed during the molding process. Also, the deformable body member provides low stress on the tread when a slit of the keyhole sipe is pulled around the body member during removal of the tread from a mold.
摘要翻译： 本发明提供了一种改进的装置，其用于模制尺寸较大的锁眼刀槽花纹，即具有比当前在胎面中形成的更宽通道的刀槽花纹，其将避免在成形期间损坏胎面并且将其从模具移除。 该装置包括细长的可变形主体构件，其具有沿着远离其的方向延伸并基本上沿其长度延伸的叶片。 主体构件还包括牢固地固定在其中的基本上延伸长度的加强构件。 加强构件为可变形的主体构件提供期望的刚性，从而在模制过程中关闭模具时，在橡胶配方的应力下沿其长度限制弯曲。 此外，当从模具中取出胎面时，当将钥匙孔刀槽花纹的狭缝拉到主体构件上时，可变形体构件在胎面上提供低应力。

摘要： A pneumatic tire with an improved balance between noise reduction and hydroplaning resistance as the tread wears. The tread of the pneumatic tire includes skewed tread blocks having walls that, as the tread wears, change the character of the lateral and circumferential channels in the tire footprint to better optimize noise reduction and hydroplaning resistance.
