ABSTRACT:
Bags having a spout opening defined by a spout edge surface affixed within the bags are sealed with a spout closure membrane first by pressing the closure membrane against the spout edge surface with a cooled plate. A heating unit which includes a heating element, which has a surface which corresponds in size and shape with the spout edge surface, then is moved adjacent the cooled plate to heat a portion of the cooled plate for sealing the closure membrane to the spout edge surface. After heating the closure membrane for sealing the spout edge surface to the closure membrane, the heating element is moved away from the plate whereby the heated portion of the plate then cools and cools the seal. After the seal is cooled, the plate then is moved away from the sealed spout and bag. The invention also includes displacement systems associated with the plate and heating unit to move them towards and away from the bag and spout and to enable applying pressure to the closure membrane and spout edge surface by means of the plate. The heating unit also includes an insulating body which surrounds the heating element.
