Apparatus and method of assembling an elongate air pumping tube into an elongate tire sidewall groove includes engaging the tire sidewall outward surface with an impact wheel at an impact location proximally adjacent and above the elongate groove as the tire is rotated. The groove is thereby spread segment-by-segment for segment-by-segment synchronous insertion of the tube into the groove. The groove is closed segment-by-segment as each spread segment is returned to its original narrower dimension utilizing elastomeric material composition properties of the tire sidewall.

Apparatus and method for manufacturing an air maintenance tire includes an air pumping tube assembly station constructing an air pumping tube sub-assembly, a tire preparation station for forming passageways in the tire to accept an outlet device of the air pumping tube sub-assembly, an air pumping tube sub-assembly installation station and a pressure regulator installation station. The air pumping tube sub-assembly inserts into an elongate tire groove opening, facilitated by groove-spreading apparatus.

Disclosed is a machine for rotation of the bead area of a green tire so that the bead areas are parallel and concentric in order to remove potential anomalies that can occur to a green tire bead portion during pre-cure handling, storing or during shaping in the tire press. The tire apparatus orients the beads of the green tire parallel and square to one another and also rotates the bead area of the tire into the proper configuration prior to cure. The bead portions of the tire maintain the parallel position as the tire is loaded into a tire mold. Also disclosed is a tire loader that has a bead support ring and paddles to grip the outer crown portion of the tire.

A tire assembly includes a tire, sidewalls, and a sidewall groove. The tire has a pneumatic cavity. The sidewall has at least one bending region operatively bending when radially within a rolling tire footprint of the tire. The sidewall groove is defined by groove sidewalls positioned within the bending region of the tire sidewall. The sidewall groove deforms segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the sidewall bending region when radially within the rolling tire footprint. An air passageway is defined by the sidewall groove and a cover strip. The air passageway resiliently deforms segment by segment between an expanded condition and an at least partially collapsed condition in response to respective segment by segment deformation of the sidewall groove when radially within the rolling tire footprint.

Disclosed is a method and apparatus for preforming a green tire into a shape that is equivalent to the shape of the green tire when placed in a closed mold. The method for preforming orients the beads of the green tire parallel and concentric to one another and also rotates the bead area components of the tire into the proper configuration prior to cure. The bead portions of the tire maintain the parallel position as the tire is loaded into a tire mold.
摘要:
A tire has an elongate profiled sidewall groove extending into a first tire sidewall from an outward first sidewall surface. An elongate air tube is positioned within the elongate sidewall groove in contact with the groove sidewalls, the air tube having an external surface configuration corresponding with and seating within the internal sidewall configuration defining the sidewall groove. The air tube when subject to outward originating impinging force collapses from an expanded unstressed configuration into a collapsed configuration to allow the tube to insert through the groove entry opening and expand outwardly once within the sidewall groove to its unstressed configuration. The configuration of the groove sidewalls capture the air tube within the groove in its expanded unstressed configuration to prevent separation of the tube from the tire during use.
