  • Patent number: 4230511
    Abstract: An endless tread assembly is fabricated on a ring having grooves and ridges which mold the radially inward surface of the tread assembly. The ring is a thin walled cylinder having a single slit or gap. The tread assembly on the ring is suspended by rotatable wheels rollable on the inward surface of the ring, so as to position an arcuate portion of the ring and tread assembly between a fixed press arm and a single movable heated press mold shoe operable to mold about a 40 degree arc of the tread assembly between the shoe and the ring backed by the press arm. Lugs on the inward surface of the ring cooperate with a latch fixed on the press arm to index selected increments of the tread assembly and ring between the press arm and mold segment. After all arcuate increments of the tread assembly have been molded and cured, the ring is opened at the gap and then simply flexed to reduce its diameter sufficiently to remove the cured tread assembly.

  • Patent number: 4215459
    Abstract: A hose built on a non-expanding, non-collapsing mandrel is removed readily lengthwise of and off the mandrel, facilitated by a tube of tough, flexible, thin anti-adherent film disposed in snug fitting contact with the length and girth of the mandrel. The tube is secured to the rigid metal member only close to the end thereof from which the hose is removed. Preferably, the tube is invaginated so as to provide inner and outer slidably juxtaposed walls. The hose built on such mandrel is moved lengthwise together with the outer wall of the tube which slides on the inner wall or the metal member. Lubrication, as by an air film, can facilitate the sliding, and does not contact the hose.

  • Patent number: 4188420
    Abstract: A device for coating wire tire cord on a spool with an agent for increasing the bond between the wire tire cord and rubber material used in the production of tires. The device is composed of at least one hollow pipe which forms a chamber in which the spools of wire are coated. The pipe is declined to help facilitate movement of the spools of wire through the pipe and allow drainage of any trapped liquid from the pipe. A hydraulic cylinder is provided adjacent the mouth of the pipe to engage and push a number of spools, in tandem, through the pipe in axially aligned, end-to-end relation. Means are supplied for circulating a liquid, containing the agent, into the chamber and for alternately creating a vacuum and pressure within the chamber to increase penetration of the liquid coating into the interstices between segments of wire cord wrapped on the spools. Other means are provided for circulating a heated fluid in the chamber to dry the liquid coating on the wire of each spool being treated.
