Abstract
Abstract A sheet material conveying and stacking apparatus is provided which utilizes a pivotally connected conveyor having air jets with a further conveyor located downstream also having air jets. The pivotally connected conveyor is placed in a first position so that sheets of material will be transported to the subsequent conveyor which utilizes air jets to displace the sheets of material onto a further conveyor which transports the sheets to a weight-responsive stacker. After the sheets have filled the stacker, the pivotally connected conveyor may be pivoted to a second position which locates the air jets above the passline of the sheets being transported by the conveyor preceding the pivotal conveyor. The sheets are then displaced by the air jets onto another conveyor located below the air jets, the sheets then being stacked in another weight-responsive stacker.
