The brake for bending sheet material disclosed herein comprises a pair of spaced base rails on which C-shaped members are positioned at longitudinally spaced points. A first member is fixed on the lower arms of the C-shaped members and has a clamping surface. A second member having a bending surface is hinged to the first member. An anvil member is interposed between the anvil member and the upper arms of the C-shaped members. The pressure member has wedges thereon which function when the pressure member is translated longitudinally to apply pressure to the anvil member. A handle is pivoted to the first member at one end and is operatively connected to the pressure member for shifting the pressure member. Novel means are provided between the wedges and the anvil member for adjusting the pressure along the anvil member. |
