A formulation is described for straightening hair comprising alkanoic acids and a diluent, wherein the diluent is advantageously present at greater than 5% by volume, and more preferably greater than 20% by volume. The inventive formulation is acidic and does not use an effective amount of an alkaline hair-straightening agent to perform the hair straightening function. Instead, the step of hair straightening is accomplished by applying the non-alkaline formulation to the hair and then either lea...

Straightening apparatus as a frame with upper and lower horizontal supports extending between uprights. Straightening roll units are mounted in cooperative relationship on these supports and are capable of sliding movement therealong. The upper straightening rolls are vertically fixed while the lower rolls are vertically adjustable to alter the rolling gap. Tension members interconnect the upper roll units and the lower support.

A machine for straightening an elongated workpiece has a plurality of coacting tools which include first and second sets of tools arranged in alternate series along a fixed longitudinal axis to engage successive longitudinally spaced portions of a workpiece positioned therebetween with its longitudinal center line generally aligned with a longitudinal axis. A cam operated lever system simultaneously reciprocates the tools of the first and second sets in opposite transverse directions relative to...

Tensioning apparatus for straightening an object such as a damaged vehicle part comprises a tensile member for attachment to the object, and a pulley for guiding the tensile member to means for engaging the tensile member. The engaging means and the pulley are mounted on a post provided with means for effecting relative movement apart of the engagement means and the pulley to tension the tensile member. An anchor is provided for anchoring the post against such tension. This apparatus is more com...

A machine is provided to straighten both the stem and the head of flanged stem workpieces such as poppet valves by rolling the stem of the workpiece between a rotary die and an arcuate stationary die. The flange of the workpiece being larger than the stem overlaps the rotary second die to have a first path of a contact portion of the flange. A straightening roller is journalled for orbiting movement on a rotary straightening member and the straightening roller has a contact area movable in a sec...

A fixture for handling small wire made of ductile materials, such as silver wire, and for moving the wire axially into a die. The fixture is made up of a fixed member and a movable member, each having wedge shaped columns having mating surfaces that interfit with each other and slide on each other. A bore is formed partly in the tips of the wedge shaped columns on the fixed member and partly in the tips of the wedge shaped columns on the movable member so that a wire directed through the bore mo...

Apparatus for straightening elongate flexible materials such as wires and the like for use with an apparatus in the production of such wires including a tensioning device for engaging at least one end of the flexible material while driving that end outwardly until the flexible material has been drawn taut whereby the taut wire trips switching means to stop the driving of the end outwardly, and the length of the flexible material is engaged by gripping means of a conveyor system for further conve...

The ends of a horizontal bar are secured to the spaced end housings of a straightening machine. Mounted on the bar are housings for two vertically spaced rows of rolls, the housings in the lower row alternating with the housings in the upper roll. During straightening, the housings for the upper rolls press upwardly on the bar while the housings for the lower rolls press downwardly on it.

A method and apparatus for straightening dents and irregularities in wheels including a spindle, a platen mounted on the spindle configured such that the wheel can be mounted on the spindle with the spindle projecting through the central hub hole and at least one actuator device positionable between the spindle and a section of the wheel to be straightened, the actuator exerting a straightening force on the rim of the wheel and a mobile device including the same.

A device for straightening metal fins on heat exchangers used in air conditioning and refrigeration systems. The device is comprised of interchangeable, detachable combs that are made to vibrate by an electrically powered vibrator. The vibrating combs can be moved easily between the adjacent fins to straighten them without requiring the force that is needed with a stationary non-vibrating comb. Various sizes of combs are provided for attachment to the vibrator.
