Edge coating in continuous deposition line

摘要

A continuous roll-to-roll deposition coating apparatus and a method to continuous coat an edge of a strip substrate are disclosed. The continuous roll-to-roll deposition coating apparatus has one or more deposition zones and one or more targets arranged in a position and orientation relative to an edge region of the strip substrate to obtain the desired coating. Position and orientation can include relative angles, displacement distance and translation position of the targets relative to the edge region. A method to continuously coat an edge region of a strip substrate in a continuous roll-to-roll deposition coating apparatus is also disclosed.
