Apparatus for forming a sealable carton for liquids accepts from a supply station a T-shaped blank of coated sheet material that is impervious to the fluid that the carton to be formed from the blank is to contain. The blank is pre-scored to delineate the side walls and ends of the carton and is further pre-scored to delineate tabs by means of which the sealing of the carton is to be effected. The apparatus for forming the carton includes a plurality of carton blank carriers mounted on a conveyor. As the conveyor carries the blank past a first operational station the side seam sealing tab is flexed forwardly and away from the mounting plate preparatory to the formation of a side seam. Following the positioning of the mandrel the blank is wrapped around the mandrel, two of the three exposed side panels of the blank being brought into surface contact with two of the faces of the mandrel and a third being brought into a position of angular confrontation with a face of the mandrel in which position its free edge spacedly confronts the side seam sealing tab that has been flexed. The carton blank carrier next brings the blank into registry with a source of heated air directed between the…
