| A wire 10 made of metal is shaped into a wire having a diameter of 5 mm by a circular die 12 and then, cut to a plurality of lengths of 500 mm. The wire 10 is heated in hydrogen atmosphere at 800.degree. C. for two hours. Then, the wire 10 is drawn by a plurality of triangular dies 14, 16, 18, and 20 sequentially without winding the wire 10 around a reel. As a result, the wire 10 is shaped into an approximately regular triangular configuration in section. The wire 10 shaped into the approximately regular triangular configuration is cut to a plurality of lengths of 40 mm and then supplied to a predetermined place for a subsequent processing. | ||||||

| Various structures exist which require an element to be turned in a certain direction. The turning is accomplished by a programmable controlled winder which includes a motor driven tool in association with a computer for automatically stopping the rotation after a pre-set number of rotations have been made. | ||||||
| 104 | Fencing with line wire tensioner | US94182 | 1979-11-13 | US4262884A | 1981-04-21 | Julian R. H. Binns; Kenneth H. Grange |
| A line wire tensioner is received in a channel extending longitudinally of a post, and the tensioner can be slid along the channel to a desired height where it is retained by suitable means such as one or more screws. | ||||||
| 105 | Material tensioning method and apparatus | US968971 | 1978-12-13 | US4218906A | 1980-08-26 | Keiichiro Yoshida |
| 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. | ||||||
| 106 | Method and apparatus for continuously hot-stretching a steel cable | US832863 | 1977-09-13 | US4112725A | 1978-09-12 | Yasuo Yamaguchi |
| A method of hot-stretching a cable and an apparatus for practicing the same in which first, second and third capstans of different diameters, having a common rotating shaft, and having grooves on the circumferential surfaces thereof for winding the cable a plurality of turns are provided in parallel between a stranding machine and a winding machine but on the side of the stranding machine. First and second guide pulleys are provided in parallel on the side of the winding machine, and the cable is wound around said winding machine through the first capstan, the first guide pulley, the second capstan, the second guide pulley and the third capstan. A front heat treatment equipment for heating the cable is provided between the first and second capstans, and a rear heat treatment equipment for heating the cable is provided between the second and third capstans. The stranding machine is operated in such a manner that the operating speed of the stranding machine is increased to a predetermined low speed after start, and after the predetermined low speed is maintained for a predetermined period of time, the operating speed is gradually increased to the rated operating speed. The front heat treatment equipment and the rear heat treatment equipment is selectively operated as required, while a part of the cable lying between the first and second capstans and a part of the cable lying between the second and third capstans is selectively subjected to a predetermined tension, so that the whole length of the cable stranded until the operating speed of the stranding machine reaches the rated operating speed after starting is continuously and effectively subjected to a hot-stretching treatment. | ||||||
| 107 | Tensioning apparatus | US600822 | 1975-07-31 | US3988007A | 1976-10-26 | Kenneth J. Freiburger, Jr. |
| A strap tensioning apparatus having a U-shaped housing with two upstanding walls, each all provided with an opening for rotatably supporting a rigid elongated bolt having a head at one end and threaded at the other end to threadedly engage a nut. A washer is secured on the bolt shank proximal to the head. Radial ratchet protrusions are coined on the washer surface and complementary ratchet engaging surfaces are formed on one wall of the U-shaped housing to provide one-way rotation of the bolt therein. A spring member may be provided between the nut and the other housing wall to exert a longitudinal force on the bolt thereby urging the ratchet members into engagement. A longitudinal slot is provided in the bolt to receive and hold a strap end as it is wound upon the bolt shank intermediate the housing walls. The housing may be resiliently attached to a ground anchor. | ||||||
| 108 | Wire drag unit | US587753 | 1975-06-17 | US3961762A | 1976-06-08 | John C. Diepeveen |
| A wire drag unit having a pair of relatively shiftable jaws. One jaw is mounted rigidly to a support and the other jaw is pivotally secured intermediate its ends to the support. The other jaw has a wire engaging a portion at one end and is provided with an L-shaped rod at the other end, the rod extending longitudinally of the jaws and provided with an adjustable weight thereon between said one end of the other jaw and the pivot point thereof. | ||||||
| 109 | Drop forging press | US3747393D | 1971-09-29 | US3747393A | 1973-07-24 | ROBRA H |
| A drop forging press has a fixed table support and a press frame comprising four columns, eight crosspieces and a plurality of tie members, the columns being of hollow polygonal cross-section, each column and being connected at its top and at its bottom to both adjacent columns by said crosspieces, the crosspieces being arranged, both at the top and at the bottom of the press frame in a rectangular configuration as seen in plan, two of said crosspieces overlapping at each end of each column, the tie members passing through each pair of overlapping crosspieces into the respective end of the respective column to secure the crosspieces to the column. Wedges may be interposed in the frame firmly to brace it. The table support may be supported by a bending support via a piston and cylinder unit. The press frame may be capable of moving up and down.

| 110 | Roll system for tensioning elongated work pieces | US3722776D | 1971-05-03 | US3722776A | 1973-03-27 | NOE O |
| A roll system for tensioning elongated workpieces such as metal bands or webs of other material, wire and the like, comprises a pair of roll supports or stands, each provided with a plurality of rolls in mirror-symmetrical relationship with the rolls of the other stand. The mirror-symmetrical rolls are interconnected by a differential transmission, e.g. a planetary gear arrangement which is coupled with a respective hydraulic motor receiving fluid from a variable-capacity hydraulic pump common to all of the motors for establishing the necessary torque at the rolls.
