ABSTRACT:
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 slat (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 (116) is made from a harder material having a relatively low coefficient of friction.
