  • Patent number: 4815351
    Abstract: The present invention provides novel apparatus for punching or drilling of a plurality of elongate, slanting bores or holes in a substantially solid slab made of a relatively rigid, penetrable material such as plastic. The apparatus comprises a punching or drilling chamber having a substantially planar top wall. A series of spikes angle downwardly and at an angle from the top wall. A feed end allows slabs of material to be fed into the punching chamber onto a planar support bed, where the slab is secured from further movement relative to the support bed. The support bed is movable in reciprocating motion upward and downward in the punching chamber in a direction parallel with the longitudinal axes of the spikes which extend downwardly from the top wall of the chamber. During the upward motion, the slab of material is forced into the spikes which pierce the slab and forms the elongated bores or holes therein. In the downward cycle, the spikes are withdrawn from the slab of material.
