• at least one roller rotatably supported by the first connection means of each of the links for supporting the conveyor chain within the track, the roller being vertically disposed for engaging the bottom wall of the track to facilitate movement of the conveyor chain through the track;
• a horizontally disposed roller rotatively supported between the longitudinally extending plates of the link for facilitating movement of the conveyor chain through the track;
• each upper, spaced parallel plate being at least partially supported by the rollers to facilitate movement of the conveyor chain;
• a plurality of product supporting grids, wherein each of the product supporting grids is supported on the first connection member of one of the links;
• means supporting each of the product supporting grids on one of the links of the conveyor chain for movement thereby along the track;
• and
• means extending between the upper plates of adjacent links and overlying the first and second connection members interconnecting the adjacent links for cooperation with the upper plates to prevent debris from entering the track, wherein the means extending between the upper plates of adjacent links comprises means for securing the product supporting grid to the first connection member of the link.

For use in a continuous proofing and baking apparatus, a conveyor system comprising:

• a track characterized by a bottom wall, side walls extending upwardly from the outer edges of the bottom wall, top wall portions extending inwardly from the upper ends of the side walls, and a slot extending longitudinally between the top wall portions;
• a conveyor chain for movement through the track and including a plurality of identical links each comprising:
• a first connection member including means positioned above the top wall portions of the track for securing a product supporting grid thereto and a pair of vertically disposed rollers rotatably supported thereon within the track and in engagement with the bottom wall of the track;
• a first plate extending longitudinally from the first connection member and secured thereto for a pivotal movement about a vertical axis;
• a second connection member connected to the opposite end of the plate for pivotal movement with respect thereto about a vertical axis;
• a second plate extending between the first and second connection members within the track;
• the first connection member of each link being connected to the second connection member of the next adjcent link for pivotal movement with respect thereto about a horizontal axis;
• the pair of vertically disposed rollers supporting the first and second connection means in the track;
• the rollers of adjacent first connection members at least partially supporting the first plate over the longitudinal slot of the track to prevent debris from entering the track through the slot and to facilitate movement of the chain through the track;
• and
• a plurality of product supporting grids each supported on the first connection member of one of the links for movement thereby along the track, wherein each of the product supporting grids includes a cover member for connecting the product supporting grid to the first connection member of the associated link of the conveyor chain, each of the product supporting grid cover members extending between the first plates of adjacent links positioned above the top wall portions of the track and overlying the longitudinally extending slot of the track for cooperation with the first plates to prevent debris from entering the track.
