The invention relates to a method of accomplishing a good seal between on the one hand a conveyor belt (2) moving over supporting rollers (6), spaced apart, and on the other hand skirting (5), arranged over the belt (2) and bearing against the top side of the moving belt (2) in order to prevent material from escaping between the belt (2) and the skirting (5), according to which the bottom side of the belt (2) is made to slide on supporting elements (7) in the regions of the skirting (5). According to the invention the supporting elements (7) are elastic and prevent the belt (2) from sagging between the rollers (6) in the regions of the skirting (5), by their elasticity making sure that the top side of the belt (2) slides against the skirting (5) without leakage. A supporting element (7) may consist of a composite material attached to a carrier (8), said material comprising at least one wear layer (13) consisting of a first elastomeric substance with a hardness of over 80 DEG Shore A and at least one elastic layer (12) between the wear layer (13) and the carrier (8), consisting of a second polymeric substance with a hardness of between 15 and 60 DEG Shore A. |
