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.

A bending brake for bending a work piece, the bending brake comprising:
- a frame
- a clamping jaw mounted to the frame for movement between a clamped position and an unclamped position;
- a bending arm mounted to the frame for movement between a staged position and an operated position when the clamping jaw is in the clamped position;
- a flexible strap supported by the frame and the bending arm for protective receipt of the work piece directly between the flexible strap and the clamping jaw;
- and
- wherein the flexible strap is disposed between the work piece and the bending arm when the bending arm is in the staged position and in the operated position.
A bending brake for bending a work piece, the bending brake comprising:
- a frame having a concave semi-cylindrical bearing surface;
- a clamping jaw mounted to the frame for movement between a clamped position and an unclamped position;
- a bending arm mounted to the frame for movement between a staged position and an operated position when the clamping jaw is in the clamped position, the bending arm having a convex semi-cylindrical bearing surface that opposes the bearing surface of the frame for pivotal movement of the bending arm with respect to the frame.
