An apparatus for transporting solid masses includes a continuously drivable first conveyor, intermittently drivable second conveyor and bridge plate interconnecting the transport path of the first conveyor and the second conveyor. The first conveyor has push bars for pushing a solid mass along the transport path of the first conveyor and forward from the terminal end of such transport path. The second conveyor has holders and means for transporting the holders, at each time of transporting, a distance twice the pitch of the holders. The solid mass is pushed out on to the bridge plate, slidingly pushed forward on the plate by a main pusher and thereby forwardly pushed out from the front end of the plate. The bridge plate has a by-pass gate, which is provided with a movable gate plate for opening and closing the gate. While the solid mass is being pushed by the main pusher, another solid mass immediately following the mass pushed by the pusher is pushed out from the first conveyor to a position over the gate by a subpusher.
