Abstract
This invention relates to the field of paperboard tray forming machines which typically consist of an upper and lower die which interlock to deform a paperboard blank. The invention is an arcuate yoke having a pair of legs to which locating stops and side guide plates are rigidly attached. The die is angled to the earth so that a blank deposited onto the die is gravity biased toward the locating stops. The yoke is vibratingly driven and the blank is vibrated into position on the lower die by contacting the locating stops and side guide plates and vibrating to the blank's lowest position on the die.
