ABSTRACT:
This disclosure relates to a retreading mold which includes first and second relatively movable platens carrying respective first and second bead aligner wheels and shafts with the shafts having opposing end portions threaded into a threaded coupling member which is in turn surrounded by a sleeve having axially opposite end portions slidably received in axial openings of the bead aligner wheels, the sleeve being normally biased axially away from one of the bead aligner wheels toward the other of the bead aligner wheels to form a sealed chamber defined by matrices carried by the platens in different closed positions of the platens, and an adjusting mechanism utilized when the matrices are open to drivably connect one of the shafts to the threaded connecting member to axially adjust the latter for locking the platens in any one of a variety of different distances in closed positions thereof.
