ABSTRACT:
An apparatus for producing a carton whereby the carton is initially obtained in the folded condition for storage and handling and whereby the carton can then be unfolded for use. The apparatus is designed for handling different types of blanks which, generally speaking, include a plurality of panels comprising side, top and bottom panels of the carton. The bottom panels are provided with flaps, and a first folding structure is provided for folding the bottom panels over onto adjacent side panels. Simultaneously, second folding means serve to fold flaps over onto the associated bottom panels, and adhesive applying means serve to locate adhesive on the blanks in selected positions. A third folding means folds the outside ends of the blank over onto the inside portions of the blank at which time folded flaps become adhesively secured. Additional adhesive or other handling means secure the outside ends of the assembly together whereby a flat condition of the carton is obtained. The carton can then be unfolded when ready for use and will automatically assume a position for loading.
