Abstract
An apparatus for forming notches on the edge of a slat; e.g. a wood slat. The apparatus includes a feeding station to feed a slat to a punching station that locates the slat along a longitudinal edge and a leading edge of the slat. A stripper plate positively locates the slat within the punch prior to the notches being punched. A pair of punches having a beveled region with a v-shaped cutout are used to form the lift hole notches.
