ABSTRACT:
The improved wrap-around carton forming and loading machine of the present invention is capable of forming cartons around the articles supported by a mandrel such that upon removal of the mandrel, the carton will engage and support the article, the improved mandrel resiliently deflects selected side walls of the carton outwardly when formed thereabout to the required sleeve configuration so that upon withdrawal of the mandrel the side walls will revert to their predetermined configuration and engage the article. In addition, the mandrel has a free end about which the end flaps of the carton may be folded to a closed position corresponding to the ultimate erect configuration of the carton.
