<p>The disclosure relates to conveying apparatus for supporting sheets during exposure to a gaseous medium, for example in drying or treating the sheets. The apparatus includes a first endles conveyor having an upstanding run, and a second endless conveyor having an upstanding run substantially parallel to said first endless conveyor upstanding run. Each of the endless conveyors includes a pair of endless drive members carrying brackets with the brackets of each pair of drive members being aligned and the aligned brackets of said first endless conveyor joined by fixed supports extending therebetween and connected thereto. The apparatus further includes movable supports, each of the brackets of the first endless conveyor further having carrier means for said movable supports disposed between said fixed supports and the brackets of the second endless conveyor having carrier means for said movable supports. An endless supporting web is associated with the first endless conveyor and is generally disposed between paths of movement of said fixed supports and said movable supports. Drive means is provided for driving said endless conveyors in unison. The apparatus further includes feed means extending between portions of said runs for sequential engagement with said movable supports carried by said first endless conveyor brackets and moving each movable support between adjacent ones of said fixed supports across the space between said runs and depositing each movable support in one of said endless conveyor brackets while pulling a generally horizontal loop of said endless supporting web. Retaining means is provided for retaining the movable supports in the second endless conveyor brackets and return means is provided extending between lower portions of said runs for returning said movable supports to said first endless conveyor and retraction of said loops.</p> |
