Patent

CA 2570517

The invention relates to a sandwich scraper strip (0) for the blade of a snowplow and provided at the top with a steel fastening neck (1) onto which a rubber body (4) having at least one embedded hard material body is molded. According to the invention, the hard material body is provided in the form of a hard metal core (6) surrounded by a steel jacket (5). This results in achieving a surprisingly high serviceable life of the sandwich scraper blade (0).

L'invention concerne une latte de déblayage de type sandwich (0) pour la lame de déblayage d'un chasse-neige, munie, en haut, d'un col de fixation (1) en acier, sur lequel un corps en caoutchouc (4) présentant au moins un corps en matière dur inséré est prévulcanisé. Il est prévu, selon l'invention, de concevoir le corps en matière dure sous forme de noyau en métal dur (6) entouré d'une enveloppe en acier (5). Cette mesure confère une durée de vie étonnamment élevée à la latte de déblayage de type sandwich (0).
