  • Double-draft wire drawing and collection machine with tension-sensitive speed control
    Patent number: 6216506
    Abstract: A double-draft continuous wire drawing and collection machine having first and second reduction dies for drawing wire in succession. A rotary advancing block driven by a variable-speed first motor draws wire rod through the first reduction die, and a rotary flyer mechanism driven by a second motor draws wire through the second reduction die as it coils wire on a stationary block. A tension control arm and rheostat regulate the speed of the first motor based on wire tension differentials detected between the rotary advancing block and the second reduction die, in order to maintain constant wire tension in that wire segment.
