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.
Claims17
A method of curing a flexible substrate, comprising the steps of:
- applying an electron-beam curable coating on a flexible substrate;
- nipping a master web to the coated flexible substrate at a nip location point;
- stretching the master web in contact with the flexible substrate;
- using an electron beam to cure the electron-beam curable coating while the master web is in contact with the flexible substrate;
- and
- separating the master web from the flexible substrate.
3 more elements
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
