ABSTRACT:
A sheet metal bending brake having a frame with a sheet metal support surface. A clamping jaw is movable relative to the frame support surface to clamp the sheet metal between the clamping jaw and the frame. The clamping jaw has a linear front edge. An elongated bending arm is pivotally mounted to the frame by an elongated flexible strap having spaced apart edges. One edge of the strap is secured to the bending arm while the other edge of the strap is secured to the frame such that the bending arm extends parallel to and closely adjacent the clamping jaw front edge.
