ABSTRACT:
Apparatus for slitting an elongated bag enclosing an article. The apparatus includes a bag support and a mechanism for engaging a portion of the bag wall adjacent the middle of the bag and pulling the engaged wall portion in a direction transverse to the axis of the bag so that the engaged wall portion extends in such transverse direction away from the article enclosed in the bag. The apparatus includes a pair of blades and mechanism for forcing the blades through the wall of the bag between the engaged wall portion and the article to puncture the bag. The blade movement mechanism is arranged to move the blades in opposite directions towards the end of the bag after the blades have so punctured the bag wall to slit the wall of the bag longitudinally.
