Method and apparatus for transverse cutting.

摘要

Compensating linkage for a continuous motion saw for elongated web plies wherein a skew arm (12) is pivotally connected at its ends to a drive arm (17) and where the drive arm (17) at its ends carries disc blades (13) and sharpening grinding stones for the blades, the ends of the drive arm (17) being pivotally connected for two degrees of freedom with brackets (20,21) which in turn are connected to an eccentrically mounted control arm (30), the linkage resulting in compensation for the skew angle to provide a cut perpendicular to the movement of the web plies and reduction of centrifugal forces and elimination of cyclic centrifugal loading on the blade grinding systems.
