  • Patent number: 5461975
    Abstract: A low friction liner is described for mounting to an agricultural material baler within the discharge chute for the baled materials. The liner includes liner plates of low friction material that are attached by a mount to the inwardly facing surfaces of the baler discharge chute. The low friction material provides inwardly facing low friction wear surfaces used to engage and guide materials along the discharge chute to a open discharge end. In one preferred embodiment, the low friction surfaces are flat and continuous from forward to rearward ends of the discharge chute plates. In another preferred form, angular indentations are made within the liner with incised or indented shoulders facing the rearward ends of the discharge chute plates to provide abutment surfaces for avoidance of "spring back" of baled materials as they are moved toward the discharge end.
