A method and apparatus for forming the mounting portion of a sidewall protector includes a rigid mold (19) in which a sidewall protector (12) can be formed and a separate plate assembly (29,31) which is moveable toward the rigid mold to form the mounting holes (10), central opening 11, and a pair of annular ribs (14,16) on opposite sides of the sidewall protector. Movement of the plate (32) is done by a plurality of springs (47) each positioned between the plate (32) and an enlarged head portion (48) of a pin (46). The springs are compressed by a linear actuator (43) and the pin (46) is connected to the mold (19) by a dowel (54) inserted through a hole (53) in the pin (46) to maintain the compression on the springs (47). This apparatus permits the use of automated strip applying equipment for laying up the sidewall protector within the mold (19) while the plate assembly (29,31) accurately forms the mounting portion which includes the mounting holes (10), annular opening (11), and the annular ribs (14,16).

A rim for a pneumatic tire carcass has a pair of rim portions which are securable together to form such rim. One rim portion is integral with a wheel hub and includes a plurality of pockets or guide openings formed therein. The other rim portion includes guide members which correspond to these pockets and which are positionable therein to position the rim portions relative to each other. Apparatus for separating the rim portions with the tire carcass mounted on them is disclosed, as is apparatus for pulling the tire carcass off a rim portion after the other rim portion has been separated therefrom. In another embodiment, a pair of rim portions are assembled by positioning posts fixed on one rim portion into angled slots defined by the other rim portion, and rotating one rim portion relative to the other, the posts being drawn into the slots during such rotation to draw the rim portions together. In yet another embodiment, the tire carcass is supplied with an inner peripheral stiffener, which is seatable in a groove formed by a pair of fixed-together rimmed portions to center the tire carcass thereon. Also, another embodiment includes an annular plate and rim portions mounted in spaced relationship on either side thereof.

Apparatus for handling a large object, i. e. , for example, an annular core on which a tire carcass is to be formed, includes an annular wall positionable about the annular core, and a diaphragm associated with the inner surface of the wall and defining with the wall a chamber into which pressurized fluid may be directed. Such introduction of pressurized fluid expands the diaphragm so that such diaphragm comes into contact with and grips the core. The core may then be moved and or turned over by manipulation of the wall.

An annular member is integrally positioned within a core portion so that a side surface of the annular portion coacts with the outer surface of the core portion to form a substantially smooth and continuous outer surface of a core. A substantially inextensible portion of the annular member is joined in end-to-end relation to an elastomer portion of the annular member. An axial end portion of the elastomer portion is mechanically locked to the core portion.

A workpiece support structure has a lower planar surface disposed above and parallel to an upper planar surface of a base assembly which is adapted to be supported on the forks of a fork lift truck for transporting the carrier and the workpiece. A plurality of air pockets are formed in one of the planar surfaces for receiving pressurized air from a suitable source so that the support structure floats on a cushion of air between the planar surfaces permitting substantially frictionless movement of the support structure relative to the base assembly for precision positioning of the support structure and thus the workpiece relative to the base assembly.

Track belts designed to fit circumferentially around a pneumatic bladder or tire carcass can be sealed against the ingress of soil and rock between the track shoes attached about the outer periphery of the belt by forming individual and permanent flat sites on the outer circular periphery of the belt so the flat undersurface of each track shoe is nested on a flat shoe site and therefore does not have triangular shaped gaps under its leading and trailing edges. A transverse rib of elastomer, raised from the surface belt between each of the adjacent flat sites further seals the belt in the narrow gaps formed between adjacent track shoes thereby preventing the ingress of soil and rock in these gaps when the shoes pass through a footprint formed as the pneumatic supported system is rolled. In elevation the outer surface of this pneumatic carcass supported belt is polygonol in appearance with a ridge or rib located at each joint between adjacent flat surfaces of the shoe sites which are circumferentially disposed around the belt.
