Abstract
A method and apparatus for folding a flat container blank about parallel score lines to bring a glue flap on the blank into juxtaposed relationship with respect to a side panel of the blank. Gripping mechanisms are associated with an intermittently operated conveyor means for pulling a blank past a glue applying station, into the folding station, and into a compressing station where the manufacturers' joint is set. Release means is provided for opening the gripping mechanisms downstream of the compressing station, and a following set of gripper mechanisms push the freed blank from the machine. Further conveyor means may be associated with the apparatus for feeding a liner to the blank to produce a laminated folded and glued blank.
