Abstract:
A coating device for two-sided coating of paper and/or paperboard, comprising a first coating device (1) arranged to coat a first side of a paper web (3) and a second coating device (2) arranged to coat a second side of said paper web (3), which first coating device (1) comprises a first metering element (4) in the form of a rotating rod and which second coating device (2) comprises a second metering element (5) in the form of a coating blade, said second metering element (5) is provided with a soft contact surface (52) against the paper web (3), which contact surface (52) is arranged to have a surface hardness in the range of 50 Shore A - 95 Shore A.
Abstract:
A method of defining a pattern of coating fluid on a surface includes introducing coating fluid into a nip defined between a surface of a first roll and a surface of second roll. The roll surfaces are urged together at the nip under a nip pressure and move in opposite directions toward the coating fluid in the nip. The amount of coating fluid metered onto the second roll surface after the nip is a function the topography of the first roll surface and the nip pressure. The first roll surface is conformable and the first and second roll surfaces are urged together. Selected portions of the second roll surface are engaged with a doctor blade to remove coating fluid therefrom, wherein a pattern of coating fluid remains on the second roll surface which is defined by at least one stripe of coating fluid. The pattern of coating fluid is transferred from the second roll surface to a moving web by a reverse kiss coating.
Abstract:
