ABSTRACT:
A machine trims the ends of decorative molding to match the contour of the face of the molding. The machine comprises a frame that supports a die. The die has an opening therethrough with a die profile that is reversely arranged in comparison with the molding face contour. A punch with a profile that is identical to the molding face contour is reciprocated into and out of engagement with the die. In a first position, the punch is out of engagement with the die such that the end of a piece of molding can be placed between the punch and the die. The punch is actuated to reciprocate into engagement with the die and shear the molding. The punch has a three-dimensional cutting edge with a point between the punch ends. The point contacts the molding first. From the point, the punch cutting edge shears the molding progressively across the molding toward the punch ends.
