The films may be applied to paper products as part of the papermaking process, or as post treatments on a coating machine.
The invention concerns a method and a device in a paper machine, coating machine, intermediate winder, unwind stand of a slitter-winder, or in any other device for treatment of a web.
At the Trois-Rivières mill, the No. 1 (coated paper) and No. 6 (supercalendered paper) paper machines, and the No. 8 coating machine will be shut down indefinitely, effective 11 June 2010.

In particular, the base paper is coated by a combination of coating by a roll coater (60) and coating by a blade coater (65A).
The present invention relates to a return trough (16) particulary suited for collecting excess coat or size back to the return circulation of a transfer roll coater or a doctor blade coater.
The present invention relates to an applicator apparatus (10) for a film-transfer coater.
Galvanizer and powder coater located in the immediate neighborhood.
A coater (24) cooperates with the peripheral surface (22) for applying coating material to the web (W) when the web(W) is guided by the surface (22) and disposed between the surface (22) and the coater (24).
The invention relates to a curtain application system which is used to apply at least two application media.
The aim of the invention is to provide a curtain application system wherein the collected application media can be used for another coating application.
The paper coater provides different wax application rates and can be reconfigured relatively quickly between different application rates.
In the manufacture of photographic materials, for example photographic films, the production process in interrupted when the coating apparatus is cleaned.
A method and an arrangement for preventing a film transfer coater comprising two rolls (1, 2) from vibrating.
The modified lignin samples were applied with a bar coater forming an even coating on the paperboard substrate.
A coating of 2-12 g/m2 is applied to each side of the coating base paper using a film press, the coating consisting of pigments with a grain size distribution for 40-60 wt% < 2 νm.
This configuration allows for adjusting the profile of the curtain film (T) for each DF coater head section (2, 3, 4).
Heads for coaters, such as blade coaters and sizers can easily be fabricated and costs can be reduced.
At least a part of the frame element (2) is fitted between the material web (W) and the curtain coater (4).
Moreover, the film may be driven to provide adjustable vibration for cleaning the coater, or conditioning or controlling the coating flow.
The coater housing (16) has an upstream lip (22) which is disposed upstream relative to the chamber (18) and adjacent to the web (W).
The so-called “coater” applies powder from the storage container to the construction cylinder.
A coater head (22) has a housing (23) which defines a coating pond (28) supplied with coating under pressure.
The invention relates to a doctor or coater blade (1) of steel, having a nickel coating comprising abrasion resistant particles, said coating being constituted by an electrolytic nickel layer comprising abrasion resistant particles.
