ABSTRACT:
A case blank feed device used in case packaging assemblies is disclosed. The device employs a pair of parallel and spaced apart bars rotatably mounted at the bottom of a case blank container having a stack of case blanks. As the bottom blank is pulled from the bottom of the container, the roller bars decrease the friction associated with the weight of the stack. In addition, the blank feed device concentrates the vacuum force along the blank edges located parallel and proximate to the roller bars so that deflection of the blank is minimized.
