  • Dual apron seal
    Patent number: 8172076
    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.
