Abstract:
A method and a device for the application of starch on a moving fiber web, especially on a packaging paper web such as a testliner or a corrugated medium web, include first applying starch to a first roll and/or a second roll and passing the fiber web through a treatment nip formed by the first roll and the second roll. At least one of the first or the second roll, preferably both rolls, have a hardness of 15 P&J (Pusey & Jones) or lower, preferably 5 P&J or lower and most preferably 1 P&J or lower. The starch is applied to the first roll and/or the second roll by a slot die and/or a slide die and then transferred to the fiber web in the treatment nip.
