Abstract

A worn vehicle tyre (10) is placed in a tread pattern cutting apparatus (20) for renewal of the pattern of the tread by a deepening thereof. The tread pattern cutting apparatus is provided with an endless chain (22) which encompasses at least two mutually spaced-apart carrier rollers (23, 24). Therebetween, the chain is in the form of a bight in which the tyre rests during the pattern cutting operation. By drive means (not shown on the drawing), the endless chain (22) is moved in its path, a tyre (10) resting in the chain being thereby rotated. By detector means (36), the distance of the tread to the cords of the tyre is sensed throughout the entire circumference of the tyre and these distances are registered so as, on the bases of the thereby registered smallest distance on renewal of the pattern of the tread, to adjust the cutting head (33) in a cutter (30) to a cutting depth which entails that the tread pattern depth will be substantially uniform throughout the entire circumference of the tyre.
