Title:
METHOD AND DEVICE FOR MECHANICALLY BUFFING WORN-DOWN TIRES
Document Type and Number:
WIPO Patent Application WO2004071750
Kind Code:
A3
Abstract:
The invention relates to a method for retreading worn-down tires (12), especially tires that have become out of true during use, especially aircraft tires. According to this method, the remaining tire tread material is equidistantly buffed relative to the upper carcass lining (26a). According to the invention, the equidistant buffing is automatized and the time required therefor is substantially shortened by optically displaying positions on the tire tread (17) in the tire circumference for the control notches (19) to be produced therein. The notches (19) produced therein are automatically measured and the measured data obtained are evaluated to determine the surface roughness settings for the roughening tool (8) to be controlled correspondingly. The corresponding device (1) is characterized by a first optical device (14, 15) for repeatedly displaying an optical mark (16, 20, 21) on the tire (12) to determine positions for control notches (19) to be produced therein, a second optical device (18) for automatically measuring the control notches (19) produced and a programmable computer (24) for evaluating the measured data of the second optical device (18) and for determining surface roughness settings for the mechanical roughening tool (8) on the basis of said data.
