    Abstract: Tire tread band having a tread surface having at least two wearing layers, a first wearing layer formed by raised elements each having a contact surface, having at least grooves of circumferential orientation, and intended to contact the road surface when new, and at least one wearing layer in contact with the road surface after the first layer has entirely worn away, and containing at least one channel extending in the circumferential direction, and opening onto the tread surface when the wearing layer that precedes it has completely worn away, each wearing layer distinct from the first wearing layer, having transverse incisions distributed in the circumferential direction, extending from a channel of the layer in a direction which is not circumferential, opening fully or partially into at least one other circumferentially oriented channel or groove, irrespective of the level of wear of the other wearing layer.

    Abstract translation: 具有胎面表面的轮胎胎面带具有至少两个磨损层，第一磨损层由凸起元件形成，每个凸起元件具有接触表面，至少具有圆周定向的凹槽，并且用于在新的时候接触路面，以及至少一个 在第一层完全磨损之后与路面接触的磨损层，并且包含沿圆周方向延伸的至少一个通道，并且当其前面的磨损层已经完全磨损时打开到胎面表面上，每个磨损层 与第一磨损层不同，其具有在圆周方向上分布的横向切口，从层的通道沿不是圆周的方向延伸，完全或部分地开放到至少一个其它周向定向的通道或凹槽中，而与水平无关 的其他磨损层的磨损。

    Abstract: Tyre tread band (1) having a tread surface (10) to come into contact with the road surface, this tread band comprising at least two wearing layers (C1, C2, C3) which are superposed in the thickness of the tread, this tread band (1) having a first wearing layer (C1) formed by a plurality of raised elements (21, 22) each comprising a contact surface, this first layer comprising at least grooves (20, 20′) of circumferential overall orientation, this first layer being intended to be in contact with the road surface when the tread is new, and at least one other wearing layer (C2, C3) coming into contact with the road surface after the first layer (C1) has entirely worn away, each other wearing layer comprising at least one channel (30) extending in the circumferential overall direction, each channel (30) opening onto the tread surface as soon as the said wearing layer is reached after the wearing layer that proceeds it has completely worn away, this tread band being such that each wearing layer (C2, C3), distinct from the first wearing layer (C1), comprises a plurality of transverse incisions (31) distributed in the circumferential direction, each transverse incision extending from a channel (30) of the layer in question in a direction which is not circumferential so as to open fully or partially into at least one other circumferentially oriented channel or groove, and do so irrespective of the level of wear of the said other wearing layer.

    Abstract translation: 具有与路面接触的胎面表面（10）的轮胎胎面带（1），该胎面带包括至少两个重叠在胎面厚度上的磨损层（C1，C2，C3），该胎面 带（1）具有由包括接触表面的多个凸起元件（21,22）形成的第一耐磨层（C1），该第一层至少包括周向整体取向的凹槽（20,20'），该第一 当胎面是新的时，该层旨在与路面接触，并且在第一层（C1）完全磨损之后，至少另一个与路面接触的其它磨损层（C2，C3）彼此完全磨损 磨损层包括在周向整体方向上延伸的至少一个通道（30），一旦达到所述磨损层的每个通道（30）在达到所述磨损层已经完全磨损之后到达胎面表面，则该胎面 每个人都穿着这样的乐队 与第一磨损层（C1）不同的层（C2，C3）包括沿圆周方向分布的多个横向切口（31），每个横切口从所述层的通道（30）沿着方向 其不是圆周的，以便完全或部分地打开到至少一个其它周向定向的通道或凹槽中，并且不管所述另一个磨损层的磨损程度如何。
