Apparatus for slant punching a plurality of elongate holes in a penetrable blank of material

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 In cycle, are withdrawn material.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