The present invention provides a doctor device for metering and/or equalizing a liquid-to-pasty medium applied to a running surface, wherein in the case of direct application the surface is a running paper web, paperboard web or other fibrous web and in the case of indirect application a transfer element which transfers the application medium to the fibrous web. The doctor device has a holder arranged on a support beam for accommodating a doctor element used for the metering and/or equalizing. The holder has a first fixed support face bar and a second moving support face bar, wherein to open and close the holder the second support face bar is displaceable respectively away from the first support face bar or toward it such that in the closed state of the holder the doctor element is fixed from the outside and in the open state of the holder it is released.

Doctor device

An applicator device and method where on the one hand adherence of particles in the dispensing area of the applicator nozzle, and on the other hand a thermal deflection of applicator device components can be prevented, or at least minimized. At least one thermal control channel through which a fluid flows is integrated into at least one of the two nozzle lips of the applicator device. Water or air can be used as temperature controlling fluids.

Application device

A support bar unit for supporting at least one functional device in a machine for the production and/or the processing of a fiber material web includes a first partial support beam and a second partial support beam. The first partial support beam supports the functional device, while the first partial support beam is supported on the second partial support beam. Further, the first partial support beam surrounds the second partial support beam, at least sectionally.

Support beam unit method of adjustment for a support beam unit

A device for the application of a liquid or viscous medium onto a running opposing surface includes a doctor blade that is mounted on a support beam, whereby the relative positions of the support beam and the opposing surface are adjustable by use of a regulating device. A flexible pressure tubing that is adjustable against the doctor blade is also provided on the support beam. In the process of controlling/regulating the device, the operating condition of the coating applicator is recorded, control values are established on the basis of the recorded results, and the regulating device and/or fluid pressure in the flexible pressure tubing is influenced on the basis of the established control values. Control/adjustments are made in such a manner that the angle of attack between the doctor blade and the opposing surface is maintained at a predetermined value. The tension condition of the flexible pressure tubing is recorded as an operating condition value and information regarding the deformation characteristics of the flexible pressure tubing, as well as the bending characteristics of the doctor blade, are considered when establishing the control values.
