The chain to be sawed to drive chain saws.

摘要

The present invention relates to a chain to be sawed to the motor to the chain saws, equipped with drive elements (2), of links of the assembly (4) and of cutting elements (3) which are connected in hinged manner to one another by means of rivets (6), the heads (7) bear on the outside of the rivet holes (10) on the lateral sides of the links. The chains to be sawed have long been known for the heads of rivets, convex and of the invention aims to transform the chain to be sawed is known, so that the assembly rivets has a total of an increased mechanical resistance to the friction conditions favorable, without this results in drawbacks to the plane of the manufacturing techniques. This object is achieved by making the heads of the rivet (7), at least approximately in the region of the hole of the rivet (10), concave.
