ABSTRACT:
A magazine pressure control is provided with pressure control wheels that are designed to regulate pressure on carton blanks being fed to a folder/gluer in a carton forming operation. These wheels are disposed around the periphery of the carton blank to urge the edges of the cartons forward and to straighten misaligned cartons. A separately controlled motor operates each half of the magazine pressure control. Each motor is controlled by a pressure sensor assembly and regulates the progression of the carton blanks through the magazine pressure control to equalize the pressure around the periphery of the carton blanks as they are presented to the pick face of the folder/gluer.
