Re-grooving possible tread and re-grooving method

摘要

Topic When being new, you propose that re-grooving depth is decided to tread.SolutionsAs for this invention, in order the carcass reinforcement body (1) to use for the tire where the Crown reinforcement body (2) is mounted in regard to the possessing and said carcass reinforcement body, being travelling tread of the thickness E which is designed, the groove of depth h (31 and 32) it is provided on the outer part surface, the travelling tread which lap it is separated into axis direction at the same time by the rib has the direction groove at least it regards (3). As for this invention, in tread, at least one inner split and lap the rubber/rubber gluing cutoff element of direction it can provide (5), the outer part wall of the tread which was seen with meridian direction section has the same contour as the contour of the wall of the re-grooving groove which it should originate in part, the point of the aforementioned wall which most leaves from rotary axis just the length h_{1 which} is smaller than tooth of flute h has been distant from the tread surface in radial, the point of the aforementioned wall which is closest to rotary axis just largest re-grooving height H features that it has been distant from the tread surface in radial.
