Abstract: A stiffening rail support is provided for attaching a stiffening rail to an outer frame for a lower blanking tool of a carton die cutting machine to discourage the flexing thereof. The stiffening rail support includes a clamping piece defining a vertically extending inner face, an opposite vertically extending outer face, and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face. A jaw element is operatively connected to the clamp piece so as to define a clamp cavity therebetween. The jaw element is movable between a clamping position for retaining a portion of the stiffening rail in the clamp cavity and a release position.

Abstract: A welding jig is provided for supporting and aligning first and second workpieces in preparation for a welding operation. The welding jig includes a first support arm extending along a first axis. A second support arm is operatively connected to the first support arm and extends along a second axis generally perpendicular to the first axis. A first clamping member is operatively connected to the first end of the first support arm for supporting a first workpiece. A second clamping member is pivotably connected to the first end of the second support arm for supporting a second workpiece. The second clamping member may be pivoted about a vertical axis for adjusting the angle between the first and second workpieces. In addition, the axial position of the second workpiece may be adjusted by moving the second clamping member along an axis parallel to the first workpiece.
