  • Patent number: 7434438
    Abstract: A folding brake includes a frame having a pair of vertically disposed and spaced side members and a lower clamp member rigidly attached to each side member and disposed in a horizontal plane. An upper clamp member is pivotally positioned in relationship to the lower clamp member for selectively clamping a workpiece positioned thereon. A first drive member generates a clamping force and selectively moves the upper clamp member. A pivotally mounted bend rail is engageable with a portion of such workpiece protruding beyond a front edge of the lower clamp member. A second drive member generates a bending force and selectively pivots the bend rail in a first direction to apply the bending force to such workpiece and in a second direction to disengage the workpiece. A controller is provided for operating the first and second drive members.
