ABSTRACT:
The invention is directed to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The saw chain includes a plurality of side cutting links, a plurality of center driving links and a plurality of side connecting links. The links are pivotally interconnected by rivets to define the saw chain. Entrainers are formed on at least a portion of the connecting links and/or drive links to reliably hold a chip cut by a forward cutting tooth in the free space between two cutting links one directly behind the other. The chip is therefore prevented from slipping relative to the saw chain and is transported out of the kerf without affecting the cutting capacity of the next-rearward cutting link.
