Abstract: A method for molding articles, particularly tires, of different diameters/circumferences including a plurality of pitches defining a mold cavity, the pitches having transverse faces in generally face-to-face abutment in a closed position of the mold cavity, and at least several of the pitches being of different lengthwise sizes. The pitches in the closed position of the mold cavity defining a predetermined mold configuration which includes portions at angles to the length of the article molded in the mold cavity. The mold configuration matches lengthwise across all of the transverse faces irrespective of the location of the pitches relative to each other and irrespective of the number of the pitches. The latter arrangement permits articles, such as new or retread tires, of different lengths but of the generally same predetermined mold configuration to be molded in a single mold.

Abstract: This disclosure relates to retread molds adapted for manual, semi-automatic, or full automatic operation particularly in bag or bladder retreading operations, and includes the following novel features:A. bead aligner wheels with circular continuous uninterrupted sealing ribs for forming annular chambers in conjunction with an associated bladder which upon pressurization of the latter results in a partial vacuum in the chambers such that the bladder will be maintained as desired during opening and closing of the matrices as well as relative movement between the bead aligner wheels;B. bladder locating means on the bead aligner wheels for centering the bladder and projections on the bead aligner wheels for preventing bladder pinching;C. cooperative means on the exterior surface of the bladder and the bead aligner wheels for venting air from between the bladder and an associated tire to atmosphere;D. port means in beads of the bladder for permitting the introduction of fluid into and the withdrawal of fluid from the interior of the bladder;E. means for achieving self-centering between a pair of relatively movable platens carrying the matrices and bead aligner wheels;F. the provision of a reservoir or sump in connection with a rotatable screw for lubricating the latter during opening of the platens, andG. a novel method of foreshortening the diameter of a tire prior to the closing of full circular matrices during a retreading operation.
