ABSTRACT:
A method of and an apparatus for the cutting of rectangular windows on mats provides a pair of blades on respective tracks which are simultaneously displaced to cut a pair of mutually perpendicular cuts in a blank positioned on a worktable. The blade carriages are actuated by pneumatic cylinders and in turn carry pneumatic cylinders for raising and lowering the blades. The margins of the mat are defined by adjustable bars whose perpendicular distances from a reference point, represented by the junction of the paths of the cuts, can be set.
