ABSTRACT:
Perimeter seals are applied to cartons to seal them in courses which encircle a carton wall at which the transverse edges of infolded carton closure flaps are disposed. Such perimeter seals create a seal of the carton interior to prevent access thereto by dust in the atmosphere, moisture, etc. Apparatus for applying the seals includes devices to apply tape around the carton wall and wipe that applied tape onto perimeter areas of the encircled wall as well as marginal areas of the four walls adjacent and orthogonal thereto.
