Title: Saw chain for a motor-driven chain saw

Abstract: The invention is directed to a saw chain for a motor-driven chain saw comprising center drive links and lateral connecting links which are pivotally connected to each other via rivets lying transversely to the longitudinal direction of the chain. Individual connecting links are configured as cutting links and have a cutting tooth with a roof bent over toward the chain center. The roof has a leading edge and a trailing edge which lie each transverse to the longitudinal direction of the chain. The leading edge is configured as a roof cutting edge and lies higher than the trailing edge which lies at a spacing above a depression. The depression is formed in the region between the rivet holes in the adjacent upper edge of the drive link and delimits a chip channel. The recess is formed asymmetrically on a drive link with respect to the center perpendicular of an imaginary connecting line between the center points of the rivet holes. In this way, a blockage-free removal of chips is ensured and a high cutting power is provided.
