ABSTRACT:
An assembly for applying coating material to top edges of containers is provided with a porous applicator which may be saturated with the molten coating material. The applicator assembly is especially adapted to contact the top curl of paperboard containers so that an amount of the molten coating material which saturates the porous applicator may be transferred to the top curl and thereby increase the top curl's circumferential rigidity upon solidification. The applicator assembly is preferably positioned laterally parallel of a linear treatment path along which the containers are conveyed in an inverted manner. Each container is rotated during conveyance along the linear treatment path such that the entire circumference of the top curl is brought into contact with the elongate porous applicator saturated with molten coating material. The container may also be rotated in contact with the applicator a successive number of turns so that a corresponding successive number of coating layers may be applied to the top curl. The coating material will thus be transferred to the top curl due to the contact that occurs between the top curl and the applicator.
