An apparatus for coating free-flowing media onto a moving paper web includes two rotatably mounted rolls having parallel axes and being driven in opposite directions. The two rolls define a roll gap for the passage of a paper web therethrough. Cooperating with each roll is an application unit for applying a free-flowing medium onto a lateral surface of the roll. A spreading device is disposed downstream of the roll gap at a side of the paper web and substantially contacts the paper web across a width thereof.

Why it's free to use
- Filed January 28, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 28, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 28, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
