  • Patent number: 8028610
    Abstract: A cutting link (1) for a saw chain includes a base body (2) and a cutting tooth (3) mounted thereon and made of hard metal. The base body (2) has rivet openings (4) and a recess (6) is formed in the base body (2) for chip removal with the recess (6) being ahead of the cutting tooth (3) in running direction. A connecting leg (8) of the cutting tooth (3) is brought into surface contact laterally of the base body (2) and the cutting tooth (3) is firmly bonded to the base body (2) by brazing. The connecting leg (8) extends so far downwardly that a lower edge (13) thereof lies lower than the recess (6). The connecting leg (8) has an upwardly raised edge (15) in its rearward region opposite the neighboring rivet opening (4).

  • Publication number: 20080072733
    Abstract: A saw chain for the guide bar of a power chain saw includes pivotably interconnected drive links, cutting links or connecting links. The cutting link has a cutting tooth and a depth limiter that leads the cutting tooth. The drive link adjacent to the depth limiter is provided with a support protuberance and a support surface that during travel of the saw chain about the end of the guide bar cooperates in a supporting manner with the depth limiter. With the saw chain extended, the support protuberance has a smaller spacing to the cutting tooth than does the depth limiter. During travel of the saw chain about the end of the guide bar, the spacing of the support protuberance to the cutting tooth increases to a reversal spacing that is greater than the spacing of the depth limiter to the cutting tooth. In a side view of the saw chain, the spacing between the cutting tooth and the depth limiter is limited by the support protuberance.
