Process and apparatus for irradiating materials provided with coating substances

摘要

A process and an apparatus (10) for irradiating materials provided with coating substances are proposed, the coating substances curing under the influence of ionising rays (15), the apparatus being provided with a source of rays (12), a ray distribution system (13) and a ray exit window (14), past which the coated material is taken for the purpose of its irradiation. At least between the material (11) in web form and the ray exit window (14), a first gaseous medium (16) can be sent past for the formation of a first boundary layer. <IMAGE>
