ABSTRACT:
Apparatus is disclosed for trimming the flange of a drawn metal container such as a food or beverage container so as to place it in condition for having the lid applied thereto. The apparatus includes a fixed trim punch secured to the base of a press, with a trim die stripper disposed around its upper edge. A trim die is secured to the movable upper bolster of the press for movement therewith. The trim die carries with it a pressure pad which is movable in a downward direction independently of the trim die and movable in an upward direction together with the die. The movement of the pressure pad is such that it will engage a portion of the flange of the container which is received within the trim punch, following which the trim die will continue its downward movement to shear off the excess material along the flange. The shearing motion is downward against the flange so that any burrs or irregularities which might occur on the remainder of the flange after the shearing operation will project downwardly. An ejection member is also provided for ejecting the container from the trim punch assembly after the shearing operation has been completed while the trim die stripper, being normally urged away from the base, will eject the trim ring.
