    摘要： A machine for splicing rubber inner tubes. The machine has a pair of heated knives which move in parallel, generally rectangular, vertical pathways to cut exposed, aligned ends of a clamped tube immediately prior to moving and squeezing the freshly cut ends together in splicing engagement. Each knife moves vertically to a position for engaging an adjacent tube end, and then transversely across the tube. Immediately upon cutting disengagement with the tube, the knife again moves vertically and to a position out of interfering relation with the moving clamps which bring and hold the tube ends in compressive, splicing engagement.

    摘要： A TIRE BUILDING MACHINE COMPRISING AN EXPANSIBLE DRUM ON WHICH TIRES ARE BUILT. THE DRUM INCLUDES A PAIR OF SETS OF SEGMENTS MOVABLE RADIALLY OF THE DRUM AXIS AND WHICH ARE COVERED WITH A RUBBER SLEEVE AND ARE DISPOSED BETWEEN TWO SETS OF FINGERS WHICH ARE ALSO MOVABLE RADIALLY OF THE DRUM AXIS. THE FINGERS ARE DESIGNED TO HOLD A PAIR OF WIRE BEADS CONCENTRICALLY OF THE LONGITUDINAL AXIS OF THE BUILDING DRUM IN EQUIDISTANT SPEED RELATION FROM THE CENTERPLANE OF THE DRUM. THE SEGEMENTS ARE MOVABLE RADIALLY OUTWARDLY OF THE DRUM TO FORM SHOULDERS IN THE CARCASS PILES ON WHICH THE BEADS MAY BE SEATED, AFTER WHICH THE TURN-UP OF THE PILES AND TIE-IN OF THE WIRE BEADS ARE MADE, AND TREAD AND SIDEWALL ARE APPLIED TO COMPLETE THE UNCURED TIRE. THE FINGERS AND SEGMENTS HAVE RIGID MATERIAL ENGAGING SURFACES. THE CENTER SECTION OF THE

    BUILDING DRUM INTERMEDIATE THE SEGMENTS HAS A SUBSTANTIALLY RIGID MATERIAL SUPPORTING SURFACE AND, TOGETHER WITH THE SEGMENTS, PROVIDES A FIRM WORING SURFACE FOR BUILDING THE TIRE.

    摘要： Tire building apparatus disclosed features a spaced apart parallel pair of continuously moving conveyors of roller chain on which a plurality of collapsible tire building drums are carried. Each drum has an extended center shaft having a freely rotatable bearer at each end which rests on and is moved by engagement with seats afforded by the side link edge shapes of the roller chain. Mechanism for collapsing and expanding the drum includes a right and left hand screw housed in the hollow center shaft. At successive work stations disposed along the conveyors each drum is stopped by swing arms movable to arrest the drum and is lifted and chucked on centers which coaxially engage the ends of the shaft. Each work station accommodates apparatus which performs a single operation, e.g. applying a liner or a cord ply, setting tire beads, enfolding carcass ply or plies about the beads, applying tread or tread and sidewall stitching, and removal of a completes carcass from the drum. Each work station is operable at its own rate and in its own time interval, relatively independently of preceding and succeeding stations. Holding stations disposed between immediately adjacent work stations have swing arms which stop forward movement of a drum on the conveyor until the following work stations can receive it. The apparatus includes a pair of upper conveyors movable continuously and oppositely above the first pair, as well as a drum elevating and a drum lowering device which cooperate with the upper conveyors to transfer a drum with a completes tire carcass thereon back to the starting position on the first conveyor.

    摘要： TIRE MOLDING AND CURING APPARATUS INCLUDING A PLURALITY OF TREAD MOLDING MEANS DISPOSED ABOUT AN AXIS AND MOUNTED FOR MOVEMENTS TOWARD AND AWAY FROM THE AXIS BETWEEN A POSITION WHEREIN THE TREAD MOLDING MEANS FORM A TIRE RECEIVING CAVITY AND A SECOND POSITION WHEREIN THE TREAD MOLDING MEANS ARE SPACED APART. CLAMPING DEVICES UTILIZED TO MAINTAIN THE TREAD MOLDING MEANS IN THEIR INNER CAVITY FORMING POSITION SO THAT ALL FORCES TENDING TO SEPARATE THE TREAD MOLDING MEANS ARE RESISTED WITHIN THE SAME AND THE CLAMPING MEANS. BEAD ENGAGEABLE MEANS ARE PROVIDED TO CLOSE THE ENDS OF THE CAVITY WITH SUCH BEAD ENGAGABLE MEANS INCLUDING MEANS TO MOLD EXTERNAL SURFACES OF AT LEAST THE BEAD PORTION OF A TIRE. BEAD ENGAGEABLE MEANS ARE RETAINED IN POSITION EITHER BY A CENTER MEMBER EXTENDING COAXIALLY OF THE CAVITY OR BY COOPERABLY ENGAGEABLE MEANS ON THE BEAD ENGAGEABLE MEANS AND TREAD MOLDING MEANS SO AS TO PROVIDE A RESTAINT FOR THE BEAD ENGAGEABLE MEANS WHICH IS ENTIRELY WITHIN THE PERIMETER OF THE TREAD MOLDING MEANS. TREAD MOLDING MEANS INCLUDING MEMBERS SUPPORTING SEPARATE MOLDING MEMBERS AND HAVING MEANS FOR PROVIDING HEAT TO THE MOLDS WITH THE HEATING MEANS EXTENDING AT LEAST COEXTENSIVELY WITH THE TREAD OF THE TIRE TO BE MOLDED BOTH IN THE DIRECTION CIRCUMFERENTIALLY ABOUT THE TIRE AND IN A DIRECTION PARALLEL TO THE ROTATIONAL AXIS OF THE TIRE.
