ABSTRACT:
A system and method for machining muntin sections and seating bars for assembly into muntin lattices using machines that notch and crimp the muntin sections and a device that pierces the seating bars. The notching machine has a notching device that forms notches in the muntin section. The crimping machine has a crimping device that forms dimples in a portion of the notched muntin sections. The piercing machine has a piercing device which forms apertures in the seating bar to receive muntin section keepers. The crimped muntin sections are assembled to the non-crimped muntin sections to create the pattern for the lattice with the dimples locking the muntin sections together. The assembled muntin sections are assembled to the seating bars using the keepers to produce an assembled lattice which is inserted between or upon glass panes of a door or window.
