243 Device for applying a cable onto a rotating surface US09995363 2001-11-27 US20020062910A1 2002-05-30 Daniel Meyer
The invention concerns a device for the application (1) of at least one cable onto a rotating receiving surface (2) revolving at a speed V2, comprising means (10) for feeding the cable that comprise at least one capstan (11) revolving at a speed V1, means (20, 30) to displace the cable transversely relative to the receiving surface (2) and means (40) to position the cable on said receiving surface, characterized in that the means (20, 30) to displace the cable transversely effect said displacement by the combination of a rotary movement about an axis perpendicular to the cable travel direction with a pivoting movement in a plane containing the axis of said rotation, the extent of pivoting being determined by the ratio between the speeds V1 and V2.
244 Method of manufacturing seals US09906758 2001-07-18 US20020014009A1 2002-02-07 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.
245 Sealing or finishing strips and carriers therefor US823795 1986-01-29 US4699837A 1987-10-13 Robert G. Bright
A carrier for a channel-shaped trimming or sealing strip is manufactured by leading a main wire between meshing teeth so as to give the wire a zig-zag configuration. The emerging wire is pushed between guide walls. Simultaneously, looped edge wires are fed in, along the walls, and mesh with the ends of the loops of the main wire. The meshed wires are fed into the mouth of a cross-head extruder. This extrudes plastics or rubber material around the meshed wires so as to hold them in meshing engagement. The resultant generally flat strip can then be bent into channel-shape.
246 Disc roller mechanism for forming helical shapes US710652 1985-03-11 US4606209A 1986-08-19 Frantisek L. Eisinger
A disc 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 disc-shaped 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 roller mechanism includes a support frame and a first set of at least two fixed position driven disc-shaped rollers and a second set of at least one idler disc-shaped rollers, said idler rollers being transversely adjustable positions relative to the first driven roller set rotatably mounted in the frame. The driven roller set usually has a roughened outer perimeter surface to facilitate drawing the feed wire through the intersecting forming rollers. If desired, the feed wire can be pulled off a rotatable supply spool such as by a pair of guiding rollers and then passed through the staggered disc-shaped forming rollers to provide the desired helical-shaped product.
247 Wire forming machine US423079 1982-09-24 US4513794A 1985-04-30 Fritz Witte
A machine for converting straightened wire into an elongated undulate comb-like product wherein hairpin-shaped prongs alternate with webs which extend in the longitudinal direction of the product has two carriers which are rotatable about parallel axes and have neighboring end faces defining a forming channel. Each carrier supports a group of equidistant tools which are reciprocable in parallelism with and are equidistant from the axis of the respective carrier. The carriers are alternately indexed in opposite directions, and the wire is fed into the channel by a pivotable portion of a wire feeding unit so that it is alternately engaged by successive tools of the one and the other carrier. The tools are shifted into the channel before they engage the wire, they remain in engagement with the wire while the respective carriers dwell between successive indexing movements, and they are thereupon retracted from the channel not later than when the respective carriers are indexed again whereby the tools are automatically separated from the wire. Levers are provided to urge the wire against the tools in the channel.
248 Mechanism for bending straight wires into zig-zags, in particular for machines for the production of diagonal grids US320011 1981-11-10 US4444227A 1984-04-24 Hans Gott; Josef Ritter; Klaus Ritter; Gerhard Ritter
A mechanism for bending a coplanar family of straight wires into zig-zags comprises deflector rollers for feeding the family of wires longitudinally in parallel with one another, bars adapted to be displaced transversely to the wires and carrying wire deflector pins, and a control device for moving the bars alternately in opposite directions transversely of the wires. In order to avoid sliding of the wires against the deflector pins during the bending operation, each bar is hinged to the one ends of at least two parallel bearer arms of equal length and pivotally supported about axes running perpendicular to the plane of bend. During each bending operation only one bar at a time can be displaced transversely by means of the control device to carry out a working stroke.
249 Method and apparatus for manufacture of wire truss and sinuous strut therefor US14988 1979-02-26 US4291732A 1981-09-29 Richard F. Artzer
A plurality of wire trusses is employed in a three-dimensional wire matrix having a foam core to provide a light-weight structural building panel. Each truss, comprised of a sinuously bent strut wire having its apices welded to lateral runner wires, is formed by a continuous bending and wire processing apparatus which simultaneously withdraws three wires from wire supplies, sinuously bends the strut wire, assembles the bent strut wire with the runner wires, welds the joints therebetween, and severs desired lengths of completed truss sections. Several wires are fed to the bending station at different speeds and intermittently via three individually automatically controlled wire storage loops. The arrangement is such that even with the several different wire feed rates, all three wires are pulled from wire supply rolls by a single motor and all three are driven to the truss fabrication station by a single motor.
250 Method for increasing the fin density of a heat exchanger US918630 1978-06-23 US4275581A 1981-06-30 Kenneth J. Miller
An apparatus (40) and method for increasing the fin density of a serpentine sheet (10) having a plurality of fins (14a, 14b, 14c), each fin having two sides (16, 18) coupled together at one end (20) with a space (22) between the sides. Blocks (30, 32) having receptacles (30a, 32a) for receiving the ends (20, 24) of one side (16) of a fin (14a) and being near opposite surfaces (A, B) of the sheet (10) are moved vertically into contact with such ends. Simultaneously, blades (34, 36), being near the opposite surfaces (A, B) of the sheet (10) are moved vertically into position at the other side (18) of the fin (14a). Then, the blades (34, 36) are moved horizontally towards the blocks (30, 32), which are now held stationary, to compress the fin (14a) a predetermined amount by moving the other fin side towards the one fin side. The blocks and blades are then withdrawn from the sheet to move another fin (14b) into position for another compressing operation. The apparatus (40) includes a mechanism (70) to prevent the sheet from fishtailing when a fin is being compressed.
251 Machine for manufacturing zig zag wire binders US933677 1978-08-14 US4178972A 1979-12-18 Ernst Pfaffle
A pair of die rolls of novel construction are disclosed which act upon a continuous wire having a preliminary zig zag formation in order to impact the bends in the wire and thus narrow the formation, preparatory to use of the wire as a ring binder. Each roll has a continuous spiral groove with a first section of progressively narrowing width which is substantially wider than the wire bend which it accommodates, and a second section of constant width. A knob or projection is formed on at least one side wall of the groove in each roll at the juncture of the first and second sections, which impacts the wire bend as it passes, giving it a set.

255 Apparatus for bending wire into a sinuous shape US44847574 1974-03-06 US3869900A 1975-03-11 NORMAN HARRY H
Wire is bent sinuously, for example to form a zig-zag shaped spring, by an apparatus having identical oscillator/overbend assemblies situated above and below the plane in which the wire is formed. Each such assembly includes a bending pin carried by a holder that is rotationally mounted on a shuttle. Drive means, including respective oscillator and translator cams, imparts rotation to the pin holder and translation to the shuttle. An overbend arm and a backup tool, driven by an overbend cam drive mechanism, overbend the wire about the bending pin of the same assembly. During a portion of each bending cycle, the bending pin of one assembly is rotated to and caused to dwell at a bending position at which the pin holder is generally perpendicular to the longitudinal axis of the zig-zag. The bending pin of the other assembly is rotated so as to contact and bend incoming wire around the now stationary bending pin of the one assembly. Concurrently the overbend arm and backup tool of the one assembly are driven into contact with sections of the wire on opposite sides of the dwelling pin so as to overbend the wire. As the overbend arm and backup tool are withdrawn, combined rotation of the bending pin holder and translation of the shuttle causes the bending pin to move laterally from the dwell position out of the newly formed convolute. The convolute at the other side of the zig-zag then is formed as the bending pin of the other assembly dwells in its bending position.
256 Device for forming a zig zag wire US3760851D 1971-12-07 US3760851A 1973-09-25 GOTT H; SCHMIDT G; RITTER K
The invention is concerned with a device for forming a zig zag wire for a structural member such as a lattice girder. The device comprises two circular discs which are mounted coaxially and spaced apart and are coupled together and driven so that they rotate constantly and synchronously in the same direction. Each disc has distributed angularly around its periphery wire bending pins which project substantially radially from the rim of the disc. Two pivoted wire bending levers oscillated in a plane parallel to the plane tangential to the discs in which in use the lattice wire will be fed to the device. Each lever has near its end a wire bending pin and is pivoted at a location near to a different one of the discs but outside the cylindrical space defined by the two discs. The levers are driven so that they oscillate in alternation and each lever has a length such that when the lever is its extreme working position its end projects beyond the plane of the remote disc so that the lattice wire is first thrust by the wire bending pin of the one lever into the path of the wire bending pins of the remote disc to bend the wire which is subsequently bent, during the return strokes of the levers, by the pin of the other lever around a pin of the other disc. Lightweight girders with parallel upper and lower flanges joined together by a zigzag bent wire web are used in large quantities nowadays for a variety of purposes. Among the various constructions a type of girder is widely used in which the lattice wire web occupies a single plane. The flanges extend along over the peaks of the lattice wire zigzags, where the lattice wires are bent, or extend along on both sides of the peaks, symmetrically with respect to the plane of the lattice.
