<p>TITLE: FLEXIBLE LINER FLAPS FOR HOPPERS OR CHUTES A flexible liner for a hopper or chute (40) has a plurality of overlapping flexible liner panels or tiles (520) secured to the walls (41, 42) of the hopper 5 or chute (40) by fixing strips (30). Each flexible liner panel or tile (520) has an elongate body (521) and a flexible fin or flap (522) formed integrally of elastomeric material, where the flexible fin or flap (522) extends at an acute included angle (a) (in the direction of flow of material through the hopper or chute (40)) to the side walls (41,42). In use, the flexible fin or flap (522) of 10 one liner panel or tile (520) overlies an elongate body (521) of an adjacent liner panel or tile (520), in the downstream direction, intermediate or adjacent the centre line of the flexible fin or flap (522) At rest, the flexible fin or flap (522) of the one liner panel or tile (520) is spaced above the elongate body (521) of the adjacent liner panel or tile (520): and, in use, the elongate body 15 (521) of the adjacent liner panel or tile (520) forms a line of deflection for the flexible fin or flap (522) of the one liner panel or tile(522), the line of deflection forming a fulcrum within the flexible fin or flap (522) such that material flowing through the hopper or chute (40) causes a portion of the flexible fin or flap (522) downstream of the line of deflection to flex; wherein: 20 at least one face (527) of at least the portion of the flexible fin or flap (522), exposed to the flow of material, is provided with at least one wear-resistant insert or tile (550,551). 1993694v1</p> |
