Saw chain for a motor-driven chain saw

A saw chain for a motor-driven chain saw, the saw chain defining a longitudinal axis and being movable in a running direction on said motor-driven chain saw, the saw chain comprising:

• a plurality of center drive links and a plurality of side connecting links, the links being pivotally interconnected by rivets lying transversely to said longitudinal axis;
• said saw chain defining a center plane passing through said longitudinal axis;
• a portion of said connecting links being configured as cutting links;
• each one of said cutting links including a rearward wall portion bent over toward said center plane to define a cutting tooth having a roof;
• said roof having a leading edge extending transversely to said center plane and defining a cutting edge;
• said roof also having a trailing edge extending transversely to said center plane and said trailing edge being at a lower elevation than said leading edge;
• individual ones of said drive links each having a body defining two rivet holes formed therein and each one of said individual ones of said drive links having an upper edge;
• said upper edge having a region extending approximately between first and second imaginary lines passing through said rivet holes perpendicular to said longitudinal axis;
• said upper edge having a recess formed therein in said region between said first and second imaginary lines;
• said recess being below or behind said trailing edge of said roof at a distance therefrom in said running direction and said recess delimiting a chip channel for guiding chips cut by said cutting edge;
• said rivet holes having center points connected by a third imaginary line;
• said recess, when viewed in side elevation, being configured in said region of said upper edge to be asymmetrical relative to an imaginary center perpendicular bisecting said third imaginary line into two equal segments and said recess having a lowest location disposed offset from said imaginary center perpendicular;
• said region of said upper edge being conjointly defined by two edge segments;
• one of said edge segments being a leading edge segment and the other one of said edge segments being a trailing edge segment relative to said running direction;
• one of said rivet holes being a forward rivet hole and the other one of said rivet holes being a rearward rivet hole relative to said running direction;
• said leading edge segment extending from approximately above said forward rivet hole and dropping in elevation relative to said third imaginary line to said lowest location;
• and,
• said trailing edge segment extending rearwardly from said lowest location with rising elevation relative to said third imaginary line to define a ramp for the chips guided through said chip channel.
