Apparatus and methods for producing coatings, such as wax or hot melt adhesive, onto the tops and necks of wine bottles or similar objects. A slot nozzle die has elongated air slots along a vertically oriented slot extrusion opening. A hot melt or wax gun is disposed above the bottle neck to apply a bead of adhesive to the bottle top. In the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow and is continued beyond that point in time, when the hot melt flow ceases. The air carries a film of coating material horizontally to the bottle neck. Means are provided for spinning the bottle about its vertical axis. The delays between the operations of the air flow and the coating flow are on the order of micro seconds. The merged coatings are heated to smooth the coating finish to produce a traditional neck seal.
Apparatus operable for producing a coating onto the top and the neck of a bottle having an elongated axis extending from a bottle bottom through the neck and the top thereof, said apparatus comprising:
Apparatus operable for applying a coating to an elongated object rotating about a vertical axis, said apparatus comprising:
Apparatus operable for applying a coating to the surface of an elongated object rotating about a vertical axis, said apparatus comprising:
Apparatus operable for applying a coating to an elongated object rotating about an axis, said object having an end and a cylindrical surface adjacent said end, said apparatus comprising:
