Abstract: A saw chain includes connecting links and drive links that are mutually connected by rivets in an articulated manner about rivet axes. The rivets project through at least one rivet opening of one connecting link and through a rivet opening of a drive link. At least one rivet has, on one end face thereof, a depression having a depression edge and a depression base surrounded by the depression edge. The distance of the depression edge from a central plane of the saw chain increases at an increasing radial distance from the rivet axis. The distance (e) of the base from the central plane does not increase at any point of the base at an increasing radial distance from the rivet axis. A greatest distance (a) of the base from the rivet axis corresponds to 50% to 100% of half the core diameter (d) of the rivet.

Abstract: The disclosure relates to a method for determining a sharpness condition of a saw chain of a chain saw. The saw chain includes at least one cutting link having an upper cutting blade. An upper cutting blade image of the upper cutting blade of the cutting link is recorded using an imaging device. An evaluation of the upper cutting blade image is performed using an evaluation unit, which includes an artificial neural network. A sharp condition and a dull condition of the saw chain are defined in the evaluation unit. The saw chain is assigned on the basis of the upper cutting blade image using the artificial neural network to the sharp condition or the dull condition.

Abstract: A cutting member of a saw chain has a cutting tooth and a cutting surface having at least one cutting edge. In a side view, looking in a sharpening direction, a first line connects an intersection between an upper edge of a roof section and the cutting surface to an intersection between an imaginary line, which extends parallel to the upper edge, and the cutting surface. A second line connects an intersection between the upper edge and an imaginary displacement of the cutting surface parallel to the contact surface at a position in which a tooth tip of the cutting tooth lies perpendicular to the running direction above a longitudinal center axis of the rearward bearing point, to a point of intersection between the imaginary line and the imaginary displacement of the cutting surface. The contact surface is aligned such that the first and second line extend in parallel.

Abstract: A guide bar for a saw chain includes an elongate, flat base body made of a basic material. The base body extends along a longitudinal center axis and, in order to guide a saw chain, has a running surface formed on an outer periphery thereof and a guide groove formed in the outer periphery of the base body.
