Abstract
An automated cup making system is provided for forming a two stage cup having an upper cup disposed upon a lower cup. An upper cup making machine is provided for forming an upper cup having an upper cup sidewall and an upper cup bottom wall disposed generally transversely to the upper cup sidewall and punched out to define a bottom wall annular border extending radially inwardly from the upper cup sidewall, the upper cup sidewall having an outwardly curled top edge. A lower cup making machine is provided for forming a lower cup having a lower cup sidewall and a bottom cup wall disposed generally transversely to the lower cup sidewall, the lower cup sidewall having a curled top edge. A sealing and assembly machine receives the upper cup from the upper cup making machine and the lower cup from the lower cup making machine for aligning the upper cup with the lower cup one above the other, flattening the lower cup curled top edge such that the upper cup bottom wall annular border is in overlapping relationship with the lower cup flattened top edge and for sonic sealing the annular border to the flattened top edge to form a finished two stage cup.
