Abstract

Abstract A packaging machine for securing a wrapper-type blank about a group of articles is provided with a continuously movable tucking stud mounted on an endless conveyor element whose working reach is disposed alongside the path of movement of a group of articles and an associated blank, said stud being engageable with a pair of article retaining and blank reinforcing flaps so as to fold such flaps inwardly of the blank to positions of enveloping relationship relative to an article. Guides are arranged so as to complete the folding of the blank in such manner as to force the flaps into secure article gripping relationship relative to the article and thereafter the ends of the blank are folded underneath the group of articles and secured together.
