Abstract: A roller conveyor supports a bale at a cutting and removing station. Side compactors and a top compactor compress the bale slightly for positioning it. The bale is pushed against a wire cutting channel in which a blade having a surface that protrudes into and forms a groove in the bottom surface of the bale is passed diagonally across the bale, with the wires springing into a recess in the blade. The blade continues to move, pulling the wire against the back wall of the recess until the wire exceeds its tensile strength and breaks. The bale is then lifted on pins so that a wire pulling blade can be moved also diagonally across the top of the bale. The pulling blade also has a forwardly inclined surface that pushes the bale down while allowing the wires to be captured in a recess in the blade. The blade is moved across the bale, capturing all of the wires and removing them from the bale. Another embodiment uses a turner to rotate the bale to cut and remove wires from adjacent sides of the bale.

Abstract: An apparatus for dividing scrap tires having a compression transport in a rotary shear station. The compression transport centers the tire and provides forces onto the treaded periphery to buckle the scrap tire. The compression transport then feeds the tire to the rotary shear station in a straight-line manner. The rotary shear station has overlapping and counter-rotating circular shears that make at least one cut along the length of the collapsed tire to produce annular tire segments. The movement of the collapsed tire relative to the rotary shear station remains a linear movement during the shearing process. Preferably, the rotary shearing station includes a pair of coaxial circular shears that are spaced apart by a third shear supported on a shaft parallel to a shaft supporting the spaced pair of shears. In this manner, the scrap tire is reduced to three segments as a pair of shearing cuts are made parallel to the flattened tread of the scrap tire.

Abstract: A mechanism for cutting a tire carcass into small sections for disposal. An array of adjoining female die sections has knife edges forming the sides of each die and shearing sections forming the corners of each die. Matching, shearing fit male punches opposingly face each die and material clasping anvils extend through each die facing the punches. A tire carcass is placed between the anvils and the punches. The anvils and punches are actuated against each other clamping the tire carcass. Punch pressure overrides the opposing anvil pressure, driving the combination of anvil, carcass and punch through the die. The forward extending knife edges penetrate the rubber of the carcass, shearing the rubber as the carcass is held taut between the anvils and the punches. The punches then proceed through the die, shearing the reinforcing cords against the corner shearing sections. The clamping action of the anvils and punches substantially prevents the carcass from escaping the cutter.

Abstract: An apparatus for removing the bead wires from a scrap tire having a pair of overlapping and counterrotating shearing members mounted on a movable carriage. The carriage provides reciprocating motion to the shearing members between two shearing work stations. While shearing action takes place at a first work station a scrap tire is fed into the adjacent work station, whereafter the bead wires of the scrap tire are first elongated and then compressed into overlying adjacent positions. Advancement of the shearing members into the tire produces a first tire shear that is at least closely tangential to the bead wires. When the pinch point of the shearing members is proximate the bead wires forward movement of the carriage is ceased. However, the tire is caused to rotate about its axis by the shearing members to produce a second shear that is substantially concentric with the bead wires, the first and second shears being a single continuous motion.

Abstract: An extrusion die for extruding helical gears or the like is formed with an extrusion passage having a predetermined draft by initially forming a blank with a central bore and frusto conical outer side surface coaxial with the bore. The formed blank is then forcibly pressed into a frusto conical bore in a die case. The frusto conical bore in the die case is tapered at an angle less than that of the outer surface of the die blank, thus when seated in the bore, radial compressive forces are applied to the blank which progressively increase in magnitude from the small diameter end of the blank to its large diameter end. While so compressed, helical gear teeth are cut into the wall of the central bore of the blank. Upon removal from the case, the blank metal expands radially to provide the machined central passage with the desired draft.

The apparatus comprises a horizontal clamping mechanism and a vertically displaceable clamping member. A measuring device is associated with the horizontal clamping mechanism and the vertically displaceable clamping member, for measuring the geometrical deformation of the tube-like members which occurs during a clamping operation. The measuring device produces a signal to stop the clamping operation before the degree of deformation of the tube-like members reaches an inadmissible value.

Abstract: A strip (10) of delicate foil is advanced longitudinally along a substantially flat path such as along a platen (104) for printing patterns of lead clusters (12) in photoresist on the foil. A margin (28) of strip (10) is formed into a guiding member such as a standing ridge (98), leaving a residue portion (29) in a desirably flat condition. Ridge (98) has a convenient reference edge (102) and a structural angle is formed by ridge (98) with adjacent foil portions. Such angle is sufficiently strong that advancing strip (10) receives no unacceptable deformation as the reference edge (102) is contacted such as to a reference wall (100) for guidance. Strip (10) is biased so the reference edge (102) maintains contact with guiding apparatus so located that the strip follows the desired path. For example, a flat member (122) is biased downward upon the residue portions (29) of strip (10) and the flat path while a side of member (122) is biased against ridge (98) and the reference wall (100).
