Abstract
A workstation for a use with a turret-type cup making machine is disclosed. The workstation is designed for use in making containers, such as paperboard style cups. The workstation includes a rotatable roller assembly and a rotationally stationary guide member which cooperate to curl the sidewall blank with respect to the bottom blank. The rollers and guide member have adjacent surfaces designed to curl the bottom edge of a sidewall blank around a lip of the bottom blank and back into the recessed area at the bottom of the container.
