Abstract
A conveyor apparatus for stacked articles, such as stacked plastic or paper bags, includes a frame, and a plurality of sprocket assemblies about which one or more conveyor chains extend. The apparatus includes a plurality of wicket wire holding assemblies mounted on the chains at spaced apart intervals for intermittent, incremental movement along a conveyor path defined by the conveyor chains. Each of the holding assemblies includes a pair of support arms, and an adjustment mechanism for adjusting the spacing between the arms. The apparatus includes an arrangement for simultaneously adjusting the spacing between the support arms of all of the holding assemblies, including an adjustment drive chain trained about the sprocket assemblies, and a mechanism for moving the adjustment drive chain relative to the conveyor chains of the apparatus.
