    • PURPOSE: To obtain a high-lug (deep-groove) tire of a high quality with limited fluidization of rubber during the vulcanization by partially cutting off the tread portion of an green tire to form a pattern groove before the unvulcanized tire is mounted into a mold to vulcanize.
      CONSTITUTION: The treaded portion of an green tire 5 is partially cut off to form a pseudo pattern groove in a roughly complementary relationship with the shaped surface of a vulcanization mold. Then, the green tire 5 is mounted in the vulcanization mold making the pseudo pattern roughly coincide with the shaped surface to vulcanize. A tread cutter of the green tire 5 is equipped with support means 6 and 11 adapted to move the green tire 5 circumferentially while supporting it 5 from inside, tread cutting devices 83 and 84 and cutter driving means 33W37 and the like.

    • 目的:为了获得高质量的高耳(深沟)轮胎,通过在未硫化轮胎安装到一个未加硫化轮胎之前,通过部分地切断生胎的胎面部分以形成图案凹槽,从而在硫化期间橡胶的流化有限 模具硫化。 构成:将生胎5的胎面部分切断,形成与硫化模具的成形面大致互补关系的假图案槽。 然后,将生轮胎5安装在硫化模具中,使假图案与成形表面大致一致以进行硫化。 生轮胎5的踏面铣刀配备有支承装置6和11,该支撑装置6和11适于沿周向移动生轮胎5同时从内部支撑它5,胎面切割装置83和84以及切割器驱动装置33-37等。
