Abstract
An apparatus and method for curing an electron-beam coating on a flexible substrate. A continuously looping master web is mated with the flexible substrate to cover the electron-beam coating when passing through an electron-beam curing unit. Curing of the electron-beam coating takes place in normal atmospheric conditions, thereby eliminating the need for nitrogen gas or the like in a curing chamber.
Claims8
An apparatus for curing an electron-beam coating on a flexible substrate, comprising:
- an electron-beam curing unit comprising an impression cylinder, an infeed nip roller, and one or more electron-beam sources;
- a flexible substrate line unit for preparing and advancing a flexible substrate coated in whole or in part with an electron-beam coating;
- and
- a master web unit for advancing a continuous loop master web into contact with the electron-beam coated flexible substrate when passing on the impression cylinder for curing;
- wherein said master web comprises one or more impressing images and corresponding registration marks.
