摘要： A bending machine for bending wire, tubing, or other elongate material, comprising a support structure and a bending head which is mounted on the support structure and which is capable of bending such material in a given plane which is fixed relative to the bending head. A feed unit is mounted on the support structure and is arranged to feed such material along a feed axis of the machine to the bending head. The bending head is rotatable about the said feed axis of the machine thereby to enable the machine to bend the material into more than one plane. Furthermore, substantially the whole of the bending head is positioned to one side of the said feed axis of the machine.

摘要： A bedding foundation box spring having novel double twist coil springs interconnecting a wooden base frame and a top wire grid. The coil springs each comprise a single length of wire having a middle section located in a diametral plane of one end convolution of the spring and a pair of spring arms coiled in the same rotational direction from opposite ends of the middle section. Each of the spring arms is formed into a helix of varying pitch which terminates in a free end of the spring arm. The free ends of the two spring arms of each coil are located on opposite sides of the end convolution of the coil and are secured to the wire grid. The novel coils are manufactured by inserting a straight length of wire through a stationary pair of forming dies and a mandrel located between the dies. With the middle of the straight length of wire located in the mandrel, the mandrel is then simultaneously rotated and moved axially while the ends of the length of wire are pulled through the stationary forming dies.

摘要： A single continuous length of spring wire is formed into a continuous length spiral or helix which is subsequently folded into a wave configuration for establishing in row form, a plurality of individual spring coils disposed generally parallel one to another. Each coil in the row is connected at its opposite ends to adjacent coils by head or connector end sections. The head or connector end sections are then formed, preferably into a planar Z-shaped configuration such that the formed connector sections at the same ends of the coils are disposed in a common plane normal to the axes of the coils which they interconnect. During forming of the end sections or heads of the coils, each connector section is deformed from a looped three-dimensional attitude into the planar Z-shaped attitude by interengagement with novel forming pins and forming dies.

摘要： The twisting apparatus comprises a transfer mechanism for transferring a formed wire spring to a working station and a pair of twisting units disposed on the opposite sides of the working station. Each unit comprises a mechanism for clamping the formed wire spring and a mechanism for twisting the formed wire spring while it is clamped between the clamping mechanisms. These mechanisms are actuated by pneumatic actuators. Means are provided for respective units for varying the twisting angle. The twisting units are also adjustable to vary the twisted portions of the formed wire spring.

摘要： This disclosure relates to a method for bending flat pattern spring strips which are characterized as including a plurality of laterally spaced apart, generally parallel torsion bars connected alternately on opposite sides by connecting arms. The method comprises the steps of forming a first 90* bend in a first plane of the spring strip along one of the connecting arms, turning the free end portion out of the first plane by twisting the connecting arm and forming a second 90* bend along the connecting arm to dispose the free end portion defining a depending leg adjacent the plane of the spring strip and angularly offset therefrom. Providing a standard fishmouth section on one end of the spring strip requires the performance of the above-described operation on two connecting arms thereby forming a first and second interconnected depending leg.
