Abstract
An ice cream sandwich with a wrapper sheet thereon is raised by an elevator to the level of a horizontal trackway during which side and bottom panels of the wrapper sheet are downfolded along the sides of the sandwich. A horizontally slidable and reciprocable pusher and folding device pushes the sandwich and wrapper sheet off the elevator device onto and along the trackway. During this operation folding devices in the form of combination vertically extending elevator guide members and folding devices which form parts of the pusher and folding device coact to infold the bottom panels of the wrapper sheet under the bottom surface of the sandwich. As the sandwich is moved over the horizontal trackway folding devices embodied in the pusher and folding device act to infold the trailing end panels of the wrapper sheet against the end walls of the sandwich; folding devices embodied in the pusher and folding device cooperate with stationary folding devices on the trackway to infold the leading end panels of the wrapper sheet against the end walls of the sandwich; stationary folding devices on the trackway upfold the bottom end-sealing panels of the wrapper sheet over the end panels and downfold the top end-sealing panels against the bottom end-sealing panels. The thus folded top and bottom end-sealing panels are then heat-sealed together following which the sandwich is moved through a cooling device to the delivery or discharge end of the trackway.
