<p>A cover (30) for a channel, such as the channel which runs along the top of a section of conveyor track (10), is disclosed for excluding foreign matter from the interior of the track while allowing a pedestal extending from the interior of the track to traverse the channel. The cover is formed from two cover halves extending inwardly over the channel from supports (24) running alongside of the channel, and the cover halves include resilient outer portions (32) and hard yet flexible inner portions (38). The inner portions contact the passing pedestal and flex out of the way as the pedestal passes between them. The outer portions provide an inward biasing force against the inner portions for holding them against the passing pedestal and returning them to a closed position after a pedestal has passed. <IMAGE></p> |
