ABSTRACT:
A stiffening assembly is provided for stiffening an outer frame for a lower blanking tool of a carton die cutting machine to discourage the flexing thereof. The stiffening assembly includes an elongated rod and 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 elongated rod in the clamp cavity and a release position.
