    Abstract: A device to actively reduce undesirable vibrations in a rotating roll includes at least one sensor arrangement to detect/measure the undesirable vibrations and at least one power unit device which, dependent upon the detecting/measuring result, influences the roll to reduce the undesirable vibration. The sensor arrangement includes at least one sensor which, relative to the rotational axis of the roll, is located radially inside the substantially circular cylindrical outer surface of the roll and/or at least one sensor which is located remotely from the substantially circular cylindrical outer surface of the roll.

    Abstract: An application unit for applying a liquid or pasty medium onto a surface moving past the application unit. This has particular application to direct or indirect application of such a medium to a paper or board web. A support beam and a front wall supported generally further from and a rear wall supported generally closer to the moving surface. The walls are spaced apart for defining a pasty medium supply gap between them and are oriented so that the supply gap generally directs the medium toward the surface. The front and rear walls can selectively receive releasable attachment of members for forming a liquid medium an application chamber, the chamber having a downstream end with a blade, an upstream end with a damming strip over which the excessive medium in the application chamber can overflow. Alternatively, a second set of attachable members may be attached to the walls for forming a free jet nozzle dosing gap that communicates with the supply gap for directing the medium to the surface. Therefore, the basic structural group remains unchanged and selectively it may be modified to either an application chamber or a free jet nozzle dosing gap. In an alternate embodiment, the elements defining the dosing gap themselves can receive the attachable elements for defining the application chamber. This enables rearranging the application unit either to define an application chamber or a free jet nozzle with replacement of fewer parts, and generally the parts that are toward the surface.

    Abstract: A device for predosing coating composition on a traveling web of paper. A guide member extends obliquely toward the web. Downstream in the path of the web past the guide member, a doctor element is supported spaced from the tip of the guide member for defining a pressure space between the a guide member and the doctor element. Coating composition is fed through a feed channel between the guide member, on the one hand, and the doctor element and the supports for the doctor element up to the pressure space, on the other hand. An exit slot from the pressure space between the guide member and the web is defined at the tip of the guide member. The guide member has a guide surface down from the tip of the guide member, on the side of the guide member away from the doctor element which faces generally toward the web. The guide surface defines a return channel for coating composition that has moved out of the pressure space and through the slot. The guide surface is gradually inclined so that the return channel gradually enlarges away from the tip of the guide member and the return channel serves as a pressure reduction space for the excess coating composition. The doctor element may be in the form of a doctor bar or a coating blade with an angle of application against the web of at most 20.degree..
