A cover for a channel, such as the channel which runs along the top of a section of conveyor track, 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 running alongside of the channel, and the cover halves include resilient outer portions and hard yet flexible inner portions. 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.

[ I claim:] [1.] In a conveyor system comprising a conveyor track, a movable member, a drive for moving said movable member along said track in a first direction, a carrier for supporting an object, and a coupling member for coupling said carrier to said movable member, the improvement comprising:a cover disposed between said movable member and said carrier for protecting said movable member, said cover comprising:first and second parallel supports spaced apart from and extending in the direction of said track;first and second resilient members connected to said first and second supports respectively and extending toward one another across said track; and,first and second edge strips connected to said first and second resilient members, respectively, being unattached to the first and second parallel supports, and held against each other in sealing engagement by said resilient members,whereby said coupling member forces apart a given length of said first and second edge strips as said movable member traverses said track and said resilient members return said given length of edge strips to a condition of sealing engagement after said coupling member passes.
