ABSTRACT:
A method of operating an orbital saw to transversely sever superposed elongated web plies into shorter length products which includes advancing along a linear path superposed elongated web plies having a cross sectional area of at least about 3.5 square inches (2200 mm.sup.2), providing a 4-bar linkage including first and second bars extending generally parallel to each other and third and fourth bars connecting the first and second bar means adjacent the ends thereof, further providing a disc blade rotatably mounted on each of the third and fourth bars, rotating the first bar about a first axis to orbit the blades with the blade orbit intersecting the linear path with the centers of said disc blades being at least 30 inches (750 mm) apart while skewing the first axis at a minor acute angle to the linear path, connecting the first and the second bar with the third and fourth bar to provide at least one degree of pivotal freedom of the third and fourth bars relative to the first and second bars, and rotating the second bar about a second axis different from the first axis to compensate for the skewing and to orient the disc blades perpendicular to the web plies in the linear path when severing the web plies.
