ABSTRACT:
Apparatus and method for forming a sealed end portion of a carton wherein at least one surface of the carton is formed from a material that functions as an adhesive when heated to a predetermined temperature and wherein each open end portion is sealed by folding minor flaps to close at least a portion of the open end portion, moving the carton by a relatively fixed elongated reinforcing strip of material, heating the material in at least a portion of a first major flap to the predetermined temperature, folding the first major flap so that at least a portion of the elongated reinforcing strip of material is located between fold lines of the folded minor flaps and the folded first major flap, folding a second major flap to a superposed relationship with the first major flap and applying pressure to the first and second major flaps against the elongated reinforcing strip of material while continuing the movement of the carton until the first and second major flaps are sealed together.
