Abstract

An apparatus for the cold plasma treatment at atmospheric pressure of a continuous web material (W) comprises at least one plasma treatment station (1) consisting of a discharge roller (2) and an adjacent electrode (3) between which the continuous web material (W) is passed, a closed chamber (7) suitable to contain said at least one plasma treatment station (1) and provided with a sealing system (8) suitable to allow the feeding of the continuous web material (W), as well as at least one injection pipe (9) suitable to introduce a treatment gas close to the electrode (3). In this way, it is possible to achieve the productivity of the continuous treatment and the flexibility of the treatment with different types of gas while dramatically reducing the operational time and cost, since there are neither problems of expensive seals and of having to re-create vacuum after changing the treatment gas, as in a vacuum apparatus, nor problems of high treatment gas consumption and of restriction to inexpensive and non-polluting treatment gases as in an open chamber apparatus.
