Abstract
A conveying apparatus comprises a conveyor belt and a housing disposed atop a conveying surface of the belt to form a chamber communicating with that surface. A fluid sealing assembly extends between the housing and the belt and comprises a profile cord engaging the belt surface. The profile cord is free to change its shape to conform to the belt configuration. The profile cord is mounted at the free ends of spring fingers which are anchored to the housing. The regions between adjacent fingers are sealed by a sealing strip which engages the fingers. The spring fingers are formed by providing parallel slits in a spring steel plate.
