摘要:
An apparatus and method provide for the alternate manufacture of permanent adhesive or repositional linerless labels utilizing the same equipment. Indicia is applied such as by using a flexographic unit in which the print cylinders are immediately thrown-off the web when the unit is turned off. Coating stations apply a repositional adhesive and release coat in the construction of repositional adhesive labels, for example, using a flexo unit in which the print cylinder stays in contact with the web after the unit is turned off to wipe excess adhesive from the print cylinder. In the construction of permanent adhesive labels a coating station for applying a release coat and a release coat curing station, as well as a hot melt permanent adhesive application station, are also provided. The permanent adhesive is applied with a slotted die head having a heat uniformity of +/- five degrees F. across its length, and applies an even adhesive coat thickness of about 0.0005-0.001 inches to +/- about 0.0001 inches.
