    摘要： Machine for forming metal wire comprising a wire forward-feeding and coiling unit (2) and a plurality of forming plates (40) arranged downstream of said unit (2), in which these plates support a respective plurality of forming heads (100), and in which said wire forward-feeding and coiling unit (2) is provided with a plurality of pairs of mutually opposing rollers (3,3A,18,19) revolving about respective parallel axles (11,12,18A,18B,19A,19B) as driven by an assembly of kinematical mechanisms with a driving wheel associated to each one of said rollers; to each one of said pairs of rollers there is associated a pair of said driving wheels, the axes of rotation of which are parallel, and which are engaged via a gear coupling with a driving shaft that is orthogonal to the plane defined by the parallel axes of rotation of said pairs of driving wheels. Said gear coupling is of the inclined-teeth type, preferably with cylindrical helical gears.

    摘要： A steel wire which has a perlite structure containing 0.8-1.0 mass% carbon and 0.8-1.5 mass% silicon and has such a hardness distribution that a surface layer ranging from the surface to a depth of 100 mu m from the surface has an average micro-Vickers hardness higher by at least 50 than that of the inner part. It is produced by shaving a steel wire having the above chemical composition and structure, patenting and drawing the shaven wire, annealing the drawn wire at 350 to 450 DEG C for strain removal, and then conducting shot peening. Thus, this steel wire can be obtained through drawing without conducting quenching or tempering, and is excellent in heat resistance and fatigue strength.

    摘要： A method and apparatus for forming a length of connected, pocketed coil springs to be used in mattresses and the like where wire (10) from a supply source is heated (16) to between 450 and 500 degrees Fahrenheit by an induction heater before the wire is coiled. Thereafter, the wire is hot coiled (18), severed (20) and cooled (22) below a temperature where a permanent set might occur fromfurther processing of the spring. Thereafter, the spring is compressed (24) in preparation for its insertion (26) into a space provided by stretchable fabric from a supply reel. The fabric (12) is folded (14) on itself to provide the space. The temperature of the spring must also be sufficiently low to contact the fabric without causing burns or other damage. After insertion of a compressed spring into the space, the fabric is ultrasonically welded (28) to create individual but connected pockets for each spring. Thereafter, the springs are oriented (30) to allow each spring to expand thereby creating the length of connected, pocketed coil springs.

    摘要： A coil of taper wire for forming coil springs, formed by winding substantially in concentric loops a quench-hardened and tempered taper wire having a successive arrangement of taper wire segments each consisting of a thick section (4), two thin sections (5) and two taper sections (6) connecting the thin sections to the opposite ends of the thick section, respectively. The taper wire is subjected to a preforming action immediately before being wound in loops on a winding drum, to form plastic bends in the thick sections and plastic bends of a radius (R₂) of curvature greater than (R₁) that of the plastic bends in the thick sections so that the taper wire is wound substantially uniform, concentric circular loops on a winding drum. When the taper wire is unwound from the coil and is subjected to a straightening process of a fixed straightening arrangement of a series of straightener rollers before being coiled in taper wire coil springs on a coil spring forming mill, the thick sections undergo a straightening action greater than that acts on the thin sections, so that the taper wire unwound from the coil of taper wire is straightened in a substantially straight taper wire and thereby the taper wire is coiled in taper wire coil springs having correct size and uniform shape.

    摘要翻译： 一种用于形成螺旋弹簧的线圈，其通过基本上缠绕在同心环中而形成淬火淬火和回火的锥形线，该锥形线具有连续布置的锥形线段，每个锥形线段由厚的部分（4），两个薄部分（5）和 两个锥形部分（6）分别将薄部分连接到厚部分的相对端。 在缠绕在卷筒上的环圈之前，锥形丝线经受预成型动作，以在厚的部分形成塑性弯曲部，并且弯曲半径（R2）大于（R1）的塑料弯曲部分在塑料弯曲部分 厚的部分使得锥形线在卷绕鼓上基本均匀地缠绕同心的圆形环。 当锥形线从线圈展开并且在卷绕在螺旋弹簧成形机的锥形线螺旋弹簧之前经受一系列矫直机辊的固定矫直装置的矫直过程时，厚部分会发生更大的矫直作用 使得从锥形线圈的线圈展开的锥形线在大致直的锥形线中被拉直，从而锥形线被卷绕成具有正确尺寸和均匀形状的锥形线圈弹簧。
