Abstract

The present invention relates to a machine (1) for regrooving the tread of a tire (3), comprising: - a cutting head (7) supporting two feed terminals and a regrooving blade, the regrooving blade being adapted to regroove at least one tread groove in a tire tread (3) to a variable depth, the two feed terminals being separated from each other, in particular by a through groove, and - a cooling conduit (9) having an inlet supplied by a cooling fluid and an outlet opening freely into the through groove in the direction of the depth of the through groove, adapted to cool the regrooving blade and the two feed terminals by means of the cooling fluid. The invention also relates to a method for regrooving the tread of a tire (3) using such a machine (1). Figure for the abstract: Figure 1
