Abstract: A process for the production and further processing of strands for Bowden cables of several wires stranded together by twisting, comprising dressing the strands after stranding between reversing rolls, subsequently stretching and again dressing between reversing rolls. Dressing is effected prior to stretching in several stages with decreasing bending radii and after the stretching again in several stages with increasing bending radii, while the stretching is performed with a force approximately within the area of the elastic limit, corresponding to 45% to 70%, preferably to 55% and 65% of the ultimate tensile strength of the strand.

Abstract: In a leveling line, the shape of a rolled material is corrected by applying a longitudinal tensile force to the material on the entrance or the exit side or both the sides of a roller leveler or within it, a warp of the material is corrected by applying a bending tension to the material within the roller leveler, and a camber of the material is corrected by applying a larger plastic elongation to either one of the widthwise edges of the material than to the other, on the entrance or the exit side or both the sides of the roller leveler or within it.

Abstract: For decreasing the width of a thin slab: a turning roll contacts the thin slab being conveyed at a certain contact angle to curve the thin slab; a tension applying device disposed in front and at the back of the turning roll, applys a tension to the thin slab forwardly and rearwardly in the direction of conveyance of the slab. Thus, the slab can be decreased in its width to a satisfactory section with no buckling loop forming portions for forming loops of the hot thin slab at the inlet and the outlet sides of the apparatus for decreasing the width of the thin slab absorb the intermittent proceeding of the hot thin slab in the direction of flow of the material. Thus, the continuous receipt and the delivery of the slab are made possible while the intermittent width decrease is performed, and the combination of the continuous casting equipment with the hot finish rolling equipment is materialized.

Abstract: In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheral zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending-unbending operations in considerably different planes and simultaneously tensioning the cable.

Abstract: A roll (10) of metal lagging is loaded onto a loading rack (14). One end of lagging (8) is drawn upwardly and away from roll (10) by a feed drive roller (38) paired with a pressure roller (36). Before it reaches these rollers (36, 38), lagging (8) is pulled upwardly between a guide roller (28) and a pressure roller (26). The axis of roller (26) is slightly below the axis of roller (28). Lagging (8) is drawn between rollers (26, 28) and around roller (28) to drive roller (38). Drive roller (38) moves lagging (8) past a cutting station into engagement with two drive rollers (86, 88) of a curling mechanism (84). When a predetermined amount of lagging (8) has passed the cutting station, drive motor (104) stops and a movable blade (46) moves downwardly past a stationary blade (48) to cut lagging (8). A pressure foot (54 ) moves downwardly with blade (46) and in cooperation with a guide block (58) forms a bend (6) on lagging (8) just before it is cut.

Abstract: A widthwise distribution of thickness of a metal strip is changed by passing the metal strip through a tool train including a plurality of tools disposed in zigzag and applying a bending under tension to the metal strip in the lengthwise direction thereof. A widthwise bending of the metal strip may be performed at the same time with said bending under tension, and a light reduction rolling of the metal strip may be performed before said bending under tension.

Abstract: Apparatus for forming a flat metal sheet into a panel having a central region of deep corrugations and a marginal edge which is either uncorrugated or has longitudinal or light traverse corrugations therein. A corrugation roll assembly forms the corrugated panel and a tension roll assembly pulls the panel through the corrugation roll assembly. A combination of cooperative corrugation roll sections and edge roll subassemblies are mounted on respective shafts with the edge roll subassembly providing a resilient gripping of an edge panel section in an angled channel region. This resilient gripping causes inward drawing of metal from the edge section into the corrugated central section to equalize the overall lengths of the respective sections.

The device comprises a structure which is movable along a path which brings it close to the periphery of the coil and to the roll gap. The structure includes suction apparatus for picking up the outer turn of the coil and apparatus for blowing air over a surface of the leading end of the foil to cause the leading end to tauten and enter into the roll gap.

Abstract: In order to improve the fatigue resistance of a cable, particularly a rubber adherable cable for reinforcing rubber articles such as vehicle tires, substantially uniformly distributed residual compressive stress is induced in substantially the complete peripheric zone of the wires making up the cable. The stress may be induced by submitting lengths of the cable to a number of elementary bending--unbending operations in considerably different planes and simultaneously tensioning the cable.

Abstract: A method and apparatus for uncoiling material such as wire, from a coil supported about a horizontal axis by a drum, including separating a loop from the coil, and bending the leading end of the material upon its exit from a pinch roll unit so that it takes a path generally parallel to that of a predetermined passline, and straightening the material once the leading end passes through the straightener roll area. An end bender roll and two of the straightener rolls are mounted on a pivotal frame connected to a piston cylinder assembly which causes the frame to be rotated through an arc in a direction to either bring the end bender roll into an operative position while the two straightener rolls are in an inoperative position, or to bring the end bender roll into an inoperative position while the two straightener rolls assume a nested relationship with a fourth roll in an operative position.

Abstract: The machine has a base provided with three rollers between which cambered strip steel is passed to remove or reduce the camber therein. Two of the rollers are mounted extending above the top surface of the base along a longitudinal axis of the base. The third roller is mounted also extending above said top surface on a block which is slidable along a slot extending along the lateral axis of the base. The cambered strip steel is passed across the top of the base between the three rollers. A drive mechanism is provided to apply a force to the third roller which bends the cambered strip steel against the two rollers to remove or reduce the camber. Removable guide strips of a case hardened or other suitable metal are provided in the top as bearing members for the strip steel. The base may be fabricated of assembled components or cast as an integral member for cost economy.

Abstract: A strip-withdrawal device for producing back tension in a plurality of metal ribbons to be wound, with at least one travelling-wave linear motor for producing the back tension, the linear motor being subject to preliminary bending against the bending forces occurring during operation, which preliminary bending is desired during operation, so that the gap between the linear motor and the plane of the strip remains of equal size over the width and thus also the braking forces acting on each ribbon.

Abstract: For use in drawing, straightening or stretching a strip of metallic material such as bars, wire, and coils, an apparatus having a pair of elastic ring-equipped roll assemblies which provide a high tensioning force for the strip material held therebetween. As the tensioning force increases, the elastic ring in each of the roll assemblies tends to deform elastically along the circumferential direction of the area which contacts the material, thus increasing the contact area over which the applied force is evenly distributed. By this means the force per unit area can be reduced. The elastic ring is mounted on a control driving shaft by at least three axially rotatable rollers, two of which are arranged to bridge the area of the material contacted by the ring.

Abstract: This invention relates to a metal coil handling system that allows the user to fully automate operations involving the conventional unwrapping of the leading end of a coil of metal from the remainder of the metal coil and subsequently threading the said leading end of the coil through rolling mill entry rolls. The invention includes equipment for disengaging and peeling this leading end of the coil away from the remainder of the coil and for holding the peeled length of metal coil strip taut throughout the mill feeding operations. The instant handling system eliminates or minimizes frictional scratches in the body of the coil normally caused by unwrapping and rewrapping of the leading end of metal during mill feeding operations.

The belt is first subjected to tensile stress, which stress is maintained during the bending process.

Abstract: A method and apparatus for removing the coil set from a coiled roll of sheet metal material or the like, and which comprises a pair of cooperating rolls defining a nip through which the sheet metal is advanced, and a deflecting roll positioned immediately downstream of the nip to flex the advancing sheet material beyond its yield point and remove the coil set therefrom. Upon stopping of the advance to permit the cutting or other processing of the sheet material, the deflecting roll is automatically withdrawn from contact with the sheet material to thereby prevent the formation of a crease in the material, and upon restarting of the advance, the sheet material is initially reversely advanced a short distance to insure that any portion of the sheet material which has not been flexed to remove the coil set will be positioned upstream of the nip before the forward advance is commenced.

Abstract: A reel and bending apparatus and method for laying pipelines from a floating vessel on the floor of a body of water in which the pipeline is capable of being unreeled from either the top or bottom of the reel and then translated through two pair of independently housed horizontally disposed rollers working in conjunction with the reel for straightening the pipe in the vertical plane.

Abstract: Certain steps in the present method of uncoiling and straightening strip material require that the pivotally mounted straightening machine have an inclined position as when operating on rather heavy and thick material. However when operating on thin strip material the pivotal straightening machine is horizontally positioned and substantially the same method steps are performed in passing the strip material to an accumulation pit. Also the coil is contained during operation to prevent uncontrolled expansion of the internal convolutions and stripping of the initial convolutions from the rotating coil and bending the same in a direction reverse to the curvature when on the coil is also contemplated by the method disclosed.

Abstract: There is disclosed a machine for the cutting of reinforcing bar which is received in coils into straight lengths. The machine includes a coil unwinding station with an independent drive means for unwinding of the coil of reinforcing bar which is controlled in response to the slack in the re-bar unwound from the coil and in response to the lengths of re-bar cut by the machine to compensate for the large mass and inertia of the coil, interfacing the coil unwinding to the remainder of the machine operation. The unwinding station includes a slack detector responsive to the uncoiled angle of the re-bar to actuate, through roller cams, switches which control the drive for the coil spindle between power-on and power-off with braking or no braking operations.

Abstract: In the uncoiling and straightening apparatus of the invention, the leading edge of the uncoiled strip material is caused to pass through a straightening machine which is supported for pivotal movement on a horizontal axis so that the machine may be moved to and from horizontal and inclined positions. The shaft providing the horizontal axis also supports a roller and the strip material is caused to contact the roller when the straightening machine is operating in an inclined position. Also to facilitate the uncoiling and bending operations on the material, a stripping apron and a back-breaker roller are incorporated in the apparatus, with the said stripping apron having pivotal movement on the said horizontal axis.

Abstract: This invention provides a method and apparatus for use with the rolling of hot metal strip. The first step in the rolling of hot metal strip is to roll a transfer bar of about 1 inch thickness, and this is ordinarily then passed through a series of finishing mills which reduce the thickness of the transfer bar to the desired final stage. The method and apparatus of this invention provides for the coiling up of a transfer bar after it has been rolled but before it passes to the finishing mill, the transfer of the coiled transfer bar from the coiling location to an adjacent uncoiling location where uncoiling can be completed or completely carried out, and initiating the coiling of a further transfer bar while the first transfer bar is still uncoiling.
