Abstract
An apparatus and method for the continuous manufacture of printed, laminated stock is provided. The apparatus is designed to use plain, uncoated webs and at separate stations along a continuous path apply a release coating, apply an adhesive, join the webs together and imprint the combined webs to yield a final, laminated and imprinted stock. By die cutting and stripping the stock at further stations, discrete elements such as labels may be produced and carried by one of the webs. The apparatus preferably includes stations for curing and remoisturizing the release coated web, whereby a known moisture content is provided for the release coating prior to the application of adhesive and joining the webs into laminated stock. The process includes providing respective webs, applying a release coating to one web, joining the two webs together, imprinting at least one of the webs and routing the combined webs to a delivery station whereby the entire process is continuous and uninterrupted.
