121 Apparatus and method for forming a wave form for a stent from a wire US13191134 2011-07-26 US09296034B2 2016-03-29 Michael Costa; Lance Ensign; Dustin Thompson; Paul Coates; Rui Lam; Larry Childs; Justin Eckhardt; Jerry Warmerdam; Charlie Dawson; Bob Boldig
An apparatus for forming a wave form for a stent from a wire includes a pair of tension wires configured to rotate about an axis. The tension wires and axis are substantially orthogonal to the stent wire disposed in a gap between the tension wires. When the tension wires are rotated, a bend is formed in the portion of the stent wire disposed between the tension wires. The tension wires may be controlled such that the axis of rotation is aligned with the particular tension wire around which the stent wire is to be bent for each particular bend formed in the stent wire, thereby preventing the particular tension wire from translating during rotation such that the tension wire behaves like a rotary pipe bending die around which the stent wire is bent. A feed assembly feeds the stent wire into the forming area between the tension wires.
122 SINUOUS SPRING FOR A FURNITURE ITEM US14470542 2014-08-27 US20160059299A1 2016-03-03 KELLY M. KNEWTSON; WILLIAM YORK, III; DAVID WILLIAM MCCUNE
A sinuous spring for a furniture item includes various elements. For instance, a sinuous spring might include bars that are both parallel and non-parallel. The parallel bars might be positioned in a middle segment, and the non-parallel bars might be positioned in opposing end spring segments. A sinuous spring might be fabricated using various devices and methods, such as a wire-fabricating apparatus including a wire-forming mechanism and a length-adjusting mechanism. The wire-forming mechanism includes one or more sets of wire-forming dies that receive a continuously fed wire and that form the wire into a wire-shape configuration (e.g., sinuous-shape configuration). The length-adjusting mechanism includes a set of grooved wheels that receive the formed wire in the grooves and rotate to stretch or compress the formed wire.
123 Method and apparatus for creating formed elements used to make wound stents US13438732 2012-04-03 US09242290B2 2016-01-26 Lance Ensign; Erik Griswold
A method for forming a wave form for a stent includes moving a first forming portion of a first forming member across an axis along which a formable material is provided in a first direction substantially perpendicular to the axis to engage and deform the formable material while engaging the formable material with a first forming portion of the second forming member. The method includes moving the first forming portion of the first forming member and the first forming portion of the second forming member across the axis in a second direction that is substantially opposite the first direction to draw and form the formable material over the first forming portion of the second forming member, disengaging the first forming member from the formable material, and rotating the first forming member to position a second forming portion of the first forming member to face the formable material.

The undulating curve is a succession of generally semi-circular sections having a generally fixed radius of curvature. The linear cast is formed on the weld wire prior to the weld wire being wound on the spool of weld wire. The linear cast is at least partially retained on the weld wire after the weld wire is unwound from the spool and during the feeding of the weld wire through a welding machine.
132 Method of manufacturing seals US09906758 2001-07-18 US06553639B2 2003-04-29 John Hobbs; David W Richards
A method of manufacturing a leaf seal for use between rotating components comprises forming corrugations within a metallic strip and feeding the corrugated strip into a seal guide. The corrugated strip is then pressed into the guide by an angled ram such that the corrugations lie at an acute angle to the perpendicular axis. The strip is then secured in a seal carrier, the free ends of the corrugations thus forming the angled sealing leaves of a leaf seal.
133 Bale tie formed with marcelled portions and package comprising compressed bale and such tie US274118 1994-07-12 US5417320A 1995-05-23 George M. Velan; Gale W. Huson; John R. Beach
For tying a compressed bale tending to expand primarily along a major axis, a bale tie made preferably from steel wire or alternatively from steel strap is bent to form two marcelled portions, which are characterized by sinusoidal undulations, which are oriented so as to be generally parallel to the major axis, and along which the tie can straighten to absorb tensile forces. A joint is formed at the opposite ends of the tie. Where bent to form the marcelled portions, the tie has an ultimate strength less than the ultimate strength of an undeformed portion of the tie but more than the ultimate strength of the joint. An apparatus for forming a wire with a marcelled portion comprises upper rolls and lower rolls, which are rotatably mounted and respectively on an upper block and a lower block. The upper block is pivotably mounted upon to the lower block.
134 Method and apparatus for forming a tube US30367 1987-03-26 US4753098A 1988-06-28 Earl Roehm; William Toy; Jerry Lamb; Clyde Morehead; Ernest Bivens; Jerry Niehaus
A method and apparatus for forming tubes, rods and the like into a serpentine configuration. A plurality of guide rails are mounted on a supporting surface and carriage bars are slideable on the guide rails. A lazy tong linkage having bend forming members mounted thereon is slideably mounted on the carriage bars. A lazy tong linkage assembly is disposed on each side of a center line and expander mechanisms are provided for forcing the two spaced lazy tong linkages apart. Drive means connected to the carriage bars drives the lazy tong linkage to a collapsed position and this movement causes the bend forming members to form a straight tube or rod into a serpentine configuration.
135 Machine for making wire comb binders US578666 1984-02-09 US4612963A 1986-09-23 Fritz Witte
A machine wherein wire is being withdrawn from a reel or barrel by a wire comb forming unit which draws the wire at a given frequency has a lever which is pivoted at such frequency by a rotary cam and carries a first roller. The lever is pivotable about the axis of a second roller and the wire is trained first over the second roller and thereupon around the first roller on its way toward the wire comb forming unit. The pivoting lever ensures that the wire is drawn from the reel or barrel at a constant speed in spite of intermittent consumption of wire in the wire comb forming unit. The diameters of the two rollers are the same.
136 Roller mechanism for forming helical shapes US701440 1985-02-12 US4546631A 1985-10-15 Frantisek L. Eisinger
A roller mechanism and method for forming helical shaped structures from a feed wire or rod, wherein the feed wire is drawn through a plurality of staggered forming rollers by rotation of the rollers, while the wire is also being rotated about its own axis so as to form the desired helical shaped product. The mechanism includes a support frame and at least four lower fixed position driven rollers and at least five upper idler rollers having adjustable positions relative to the lower rollers rotatably mounted in the frame. The lower rollers usually have a roughened or grooved surface to facilitate drawing the feed wire through the staggered forming rollers. If desired, the feed wire can be pulled off a rotating supply reel by a pair of guiding rollers and then passed through the forming rollers to provide the desired helical shaped product.
137 Bookbinding wire stock production method and apparatus US190447 1980-09-24 US4373558A 1983-02-15 Kenneth H. Dawson
An illustrative embodiment of the invention produces comb-like bookbinding wire stock in a manner that significantly reduces wire breakage during manufacture as well as unequally stressing or stretching or marring the surface finish of the wire from which the stock is formed. An indexing unit drives a pair of forming arm members that pivot under the control of a cam surface. These members align and wind a wire strand onto pins that protrude radially from a pair of parallel, axially spaced rings. Operation of a reciprocating side pusher and center pusher shaft press the wire strand onto the adjacent pins and a wire flattening roller presses one side of the partially formed stock against the adjacent pin surfaces to produce the "back" for the comb-like stock. A rotating pinch roll "sets" the fingertip portions of the tines on the stock. Because the plane surfaces of the circular rings are parallel, substantially less time is required to set up the machinery that characterizes the invention and undertake a production run than that which characterized prior art devices.

This invention describes a method of making a sheet metal zig-zag key for a lock. The technique of making a zig-zag key, either as a duplicate of another or in the original form, consists of passing a heavy current through the key so as to get it into a plastic state such as, for example, a red heat, and then deforming it into the desired shape.
140 Pliers-type wire-crimper US48646574 1974-07-08 US3918472A 1975-11-11 BROWN FRANK R
A wire-crimper capable of shaping a section of small diameter wire into a generally offset-U-shaped or ''''crimped'''' configuration, while leaving the remaining wire unaffected, is composed of two pairs of interfitting and pivotally connected arms, the arms of each pair being planarly parallel but axially spaced from each other on the pivoting axis. Each arm has a crimping edge beyond the region where the two pairs are pivotally interconnected and intermeshed along the pivot axis. The crimping edge of each arm faces toward the crimping edges of the arms of the other pair. The wire shaping is accomplished by three of the crimping edges as they axially overlap while the fourth edge prevents bending of the remaining wire during the crimping operation.
