Abstract

See full text

A tool system comprises a circular saw blade which is adapted to be moved in a reciprocating manner between an elevated, RETRACTED, INOPERATIVE position and a lowered, EXTENDED, OPERATIVE position so as to repeatedly form slits within a packaging structure at a plurality of positions which are defined at predeterminedly spaced locations along the longitudinal extent of the packaging structure. A circular saw blade guide member is disposed adjacent to the outer periphery of the circular saw blade and is movable along with the circular saw blade between its elevated, RETRACTED, INOPERATIVE position and its lowered, EXTENDED, OPERATIVE position. Accordingly, as the circular saw blade is moved from its lowered, EXTENDED, OPERATIVE position back to its elevated, RETRACTED, INOPERATIVE position, the guide member will in effect guide the circular saw blade back through the slit formed within the packaging structure so as to facilitate the retractive movement of the circular saw blade, back through the slit formed within the packaging structure, thereby effectively eliminating the tendency of the circular saw blade to otherwise encounter the edge or wall portions of the packaging structure, which define the slit, in an obstructive manner as the circular saw blade is moved from its lowered EXTENDED, OPERATIVE position to its elevated RETRACTED, INOPERATIVE position in preparation for the performance of a sub-sequent cutting operation.
