Abstract
A clamping head assembly for clamping a first member to a second member at a miter joint, where the clamping head assembly includes a first fence member with a first positioning edge for positioning an edge of the first member and a second fence member that is movable and includes a second positioning edge for positioning an edge of the second member. The second positioning edge is arranged at an angle with respect to the first positioning edge. Additionally, the first fence member and the second fence member are configured and arranged so that the angle is approximately bisected by the miter joint formed between the first and second members. The second fence member is movable in a direction that is approximately perpendicular to the miter joint, whereby a normal force is generated upon the miter joint. Furthermore, the present invention also relates to a frame making machine that includes the clamping head assembly just described.
