ABSTRACT:
A method and apparatus for forming a decorative seal on envelopes and the like is disclosed. The envelopes to be embossed are intermittently transported along a conveyor past various processing stations. At a first station, a quantity of heated molten seal material is deposited at a desired location on an envelope. The envelope is next transported to a first cooling station where a stream of cooled air is directed against the deposited molten material for partial cooling. At a subsequent stamping position, a cooled embossed die is applied to the seal material to form an embossed decorative pattern therein. The envelope is then transported to a refrigerated chamber which accelerates solidification of the stamped seal material to form an embossment. The timing of the intermittent movement of the conveyor is controlled in accordance with the quantity, temperature, and type of seal material used to form the embossment.
