Abstract (en)
[origin: WO2016020722A1] Cutting chain for chain saw machines for cutting ornamental stones, comprising internal links (1) and external links (2) connected together in an articulated manner by means of articulation pins (3), in which the links (1, 2) are configured in a manner so as to create a labyrinth interspace (12) with minimal size, which prevents the entrance of impurities inside the external link (2). The result is that of preventing the formation of a thickness of an extraneous material (mud, dust, etc.) inside the external link (2), which could obstruct the free rotation of the links in the realignment step and then give rise to stresses on the articulation pin (3).
