"Dual Apron Seal"
Abstract: A seal member for sealing a conveyor belt is a monolithic homogeneous piece of material having opposite first and second halves and comprises first and second primary seals and first and second secondary seals. The first secondary seal is resiliently movable relative to the first primary seal. The second secondary seal is resiliently movable relative to the second primary seal. The first primary seal and the first secondary seal are part of the first half of the seal member. The second primary seal and the second secondary seal are part of the second half of the seal member. When the seals on one of the first and second halves of the seal member become excessively worn, the seal member can be flipped so that the seals on the other half of the seal member can be utilized.
