Abstract: A cutting apparatus for an elongate wire is provided, and includes a housing that supports a first cutter that has a body, a recess, and a cutting blade. The cutting blade is disposed upon a wall of the body that defines the recess, the first cutter is fixed with respect to the housing. The housing additionally supports a second cutter that has a body, a recess, and a cutting blade, wherein the cutting blade is disposed upon a wall of the body that defines the recess. The second cutter is normally positioned with respect to the first cutter such that the recess of the first cutter is aligned with the recess of the second cutter, and is movable to a second position where the recess of the second cutter translates with respect to the recess of the first cutter, such that the respective cutting blades translate toward each other.

Abstract: An apparatus for forming a carcass for encasing a tubular member including a driven rotor (20) having a front face rotatable about a pivot axis and a spool mandrel (38) positioned eccentrically on the driven rotor (20). The spool mandrel (38) is adapted to rotatably mount a roll of coiled strip material (32). The rotor (20) includes at least one counterweight (60) mounted on the front face that is dynamically movable to at least partially balance the changing weight of the roll of strip material as the strip material (32) is removed from the roll. At least one pusher roll assembly (75) is mounted on the front face and contacts a portion of the strip material (32) to partially deform the coiling of the strip material as the material is removed from the roll. An anti-kink roll assembly (90) prevents kink deformation of the strip material (32) during the formation of the carcass.

Abstract: A tire with a tire bead having a cross sectional profile including a relatively wide base section and a top section that is tapered on at least one side, with the tire bead being embedded directly in the tire body without the use of an extension. Also, a tire with a tire bead having a cross sectional profile including a relatively wide base section and a top section with one tapered side and one untapered side, with the tire bead being embedded in the tire body along with an extension. Also, a method of building a tire where the tire bead and extension are assembled into the tire body at the tire building drum of the tire assembly machine, and the tire bead and extension are not pre-assembled prior to being introduced onto or into the tire body.
Abstract: Th leading end of a tire bead wire is gripped in the usual manner radially inwardly of the inside diameter of the bead as a forming drum is rotated to form a hoop-like bead of multiple convolutions of the wire. Upon release by the gripper members, the leading, initially gripped end of the wire moves into a void provided therefor on the inner diameter of the bead. A member is then rotated to bring the outer surface of an arm into physical engagement with the end of the wire at the inner diameter of the bead, urging it into tight engagement with the tacky surfaces of adjacent wire convolutions, thereby ensuring that the inner wire end does not become disengaged. Certain elements may be mounted in either of two positions to effectively double their useful life. The stitching operation may be performed while the forming drum is still rotating, i.e., as the bead is being formed, whereby operation of the invention does not add to the time required to fabricate the beads.
