US Patent 11975877 Case former with case-squaring assembly

Various embodiments of the present disclosure provide a case former configured to receive a case in a blank configuration, open the case into a tubular configuration, fold the lower minor flaps to manipulate the case into a partially closed-bottom configuration, square the case while in the partially closed-bottom configuration, and fold and tape the lower major flaps shut to manipulate the case into a closed-bottom configuration. The squaring step ensures that the case has a rectangular cross-section after taping rather than a rhomboid cross-section.
