An apparatus and method for printing or coating material and supporting the material during printing or coating thereon by either offset-gravure or direct roll equipment includes a cylindrical support member having flexible bristles radiating therefrom. The bristles are of a suitable diameter, length and spacing to form a generally cylindrical brush that is oriented in spaced relation to a contact printing or coating roller and adapted to yield or bend when coming in contact with contoured or uneven portions of the material and thereby fully support the lower surface of the material as the upper surface of the material is being printed upon or coated.

Why it's free to use
- Filed May 17, 1993 and granted December 28, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 17, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
