Abstract

La présente invention est relative à une lance pour la projection d'un matériau. Cette lance 1 comprend, à sa bouche 2, des moyens 3 agencés pour diriger et répartir le matériau suivant des directions transversales à l'axe 4 de la lance, ces moyens étant montés sur la lance de manière à pouvoir être déplacés, pour faire varier la distance 5 les séparant de la bouche 2 de la lance, suivant une direction parallèle à l'axe 4 de cette dernière afin de modifier l'angle de projection alpha par rapport audit axe. L'invention est applicable en particulier pour le gunitage dans des conduits ou orifices de faible section.
