Abstract

La présente invention concerne un guidage pour chaînes de haveuse, constitué par des glissières de section à peu près en H avec un profilé en U tourné vers l'extérieur. La glissière 2 est subdivisée continûment dans le sens longitudinal de telle manière que les éléments des glissières 2a, 2b sont montés sur le support de guidage de façon que leur distance soit variable afin de compenser l'usure éventuelle des surfaces de guidage de chaque glissière. Ces chaînes de haveuse peuvent être utilisées en particulier pour le découpage de roches contenant un silicate ou du quartz.The present invention relates to a guide for chainsaw chains, consisting of slides of approximately H-section with a U-shaped profile facing outwards. The slideway 2 is continuously subdivided in the longitudinal direction so that the elements of the slideways 2a, 2b are mounted on the guide support so that their distance is variable in order to compensate for possible wear of the guide surfaces of each slide. These chainsaw chains can be used in particular for cutting rocks containing silicate or quartz.
