ABSTRACT:
Tire mold apparatus for vulcanizing a tread onto a tire casing. The apparatus utilizes matrix segments provided with grooves that receive tubing. Steam is passed through the tubing so as to heat the matrix segments. The tubing is rigidly joined to a steam-fitting block. Fracturing of the joint between the tubing and the block due to differences in thermal expansion is avoided by slidably mounting the fitting block relative to the matrix.
