An elastomeric seal member (94) includes a split, V-shaped upper edge portion including and formed by branches (110, 112) that angle away from each other and toward opposite sides (88, 90) of adjacent conveyor slats (80) of a reciprocating slat conveyor. The seal member (94) includes a base portion (96) that is retained within a longitudinal groove (102) formed in a first side (88) of a first conveyor slat (80). It also includes an outboard portion (98) that is situated within a gap (92) between first and second conveyor slats (80). The inboard and outboard portions (96, 98) are interconnected by a neck (100) that extends through a slot (106). The neck (100) and outboard portion (98) form a dihedral corner (108) where they are joined. This formed corner (108) and contact between neck (100) and a lower slot surface (114) holds and braces the seal member (94) against rotation in the gap (92) in response to downward forces acting on the outboard portion (98) of the seal member (94). The main body of the seal member (94) is made from a relatively soft, resilient elastomeric material. Seal member branch portion (116) is made from a harder material having a relatively low coefficient of friction.
Joint d'étanchéité élastomérique (94) dont la partie supérieure, en forme de V, se divise en deux branches (110 et 112) orientées vers les côtés opposés (88 et 90) des palettes adjacentes (80) d'un convoyeur à mouvement alternatif. Le joint d'étanchéité comporte une base (96) qui est retenue à l'intérieur d'une rainure longitudinale (102) pratiquée dans un premier côté (88) d'une première palette (80). Le joint comporte aussi une partie en saillie (98) qui se loge à l'intérieur de l'espace (92) qui sépare une première et une deuxième palette (80) du convoyeur. Les deux parties du joint d'étanchéité (96 et 98) sont reliées par un col (100) passé à travers une fente (106). Le col (100) et la portion en saillie (98) forment un coin dièdre (108) à leur point de jonction. Ce coin (108), ainsi que le contact entre le col (100) et la surface inférieure de la fente (114), assurent le maintien du joint d'étanchéité (94) et empêchent sa rotation à l'intérieur de l'espace d'écartement (92) sous l'effet des forces descendantes exercées sur la partie en saillie (98) du joint d'étanchéité (94). Le corps principal du joint d'étanchéité (94) est fait d'un matériau élastomérique relativement souple et élastique. Les branches (116) sont faites d'un matériau plus dur à coefficient de frottement relativement faible.
