Abstract: A loading arrangement in a paper machine doctor includes a blade carrier, a blade holder, and loading devices to turn the blade holder in relation to the blade carrier and thus to press the doctor blade against the surface to be doctored. The loading devices include at least one operating device including longitudinally arranged loading components and a pressure medium connection extending to each of the loading components to make the profile of the doctor blade conform to the surface to be doctored.

Abstract: A dryer section in a paper machine which comprises a number of dryer groups, each having drying cylinders, reversing cylinders arranged between adjacent pairs of drying cylinders and a wire which presses the web against heated cylinder faces of the drying cylinders whereas the web remains at the side of the outside curve on the reversing cylinders. The dryer groups are arranged in two or more stories. Some of the dryer groups in the dryer section are placed in the basement spaces underneath the machine hall level, and some of them are placed on the machine hall level.

Abstract: The invention concerns an adjustable-crown roll having a stationary roll axle which is supported on the machine frame by means of articulated bearings, and a roll mantle which is arranged to revolve on the axle. Hydrostatic loading members or an equivalent pressure fluid chamber or series of chambers are arranged in the space between the axle and the roll mantle. By means of the loading members or equivalent, the profile of a nip formed with a counter-roll of the roll is regulated. A support bushing arranged concentrically with the roll mantle is attached to one end of the roll mantle and revolves along with the roll mantle. A bearing is installed on the support bushing. The bearing receives axial forces from the roll mantle and transfers the same to the machine frame through the non-revolving bearing bock or housing of the bearing. The bearing is arranged, in the axial direction, outside the roll, whereby the roll is suitable for use as a hot roll.
