  • Method and apparatus for roll forming convoluted springs
    Patent number: 5732584
    Abstract: An apparatus for roll forming convoluted springs in which a tempered steel strip is fed between a pair of forming rolls which produce a continuous convoluted steel strip. A compression mechanism downstream of the pair of forming rolls compresses the continuous convoluted steel strip to set the angular relationship of the adjacent legs of the convoluted steel strip. A cut-off mechanism disposed downstream of the compression mechanism device severs from the convoluted strip individual convoluted springs having a predetermined number of convolutions and desired spring characteristics.
