Abstract
The invention provides a coating method and machine for applying pressure sensitive adhesive to one side of a web and release material in the form of a silicone coating to the other side of the web. The web is printed in rows of labels and is cut into the rows before being wound up after the coating process. The machine can also be used for transfer coating the adhesive onto the web by passing a release web through the adhesive applicator. Also, the machine can be used for making laminated webs. The machine has novel constructions of adhesive and silicone aplicators and curing devices.
