摘要： A sealing strip of a suction roll (4) for a material web machine includes a longitudinal strip element (3) and a longitudinal holder (2) shaped as a U profile open in the direction of a facing surface (41). An element first layer (31) is an easily adjusting material and a second layer (34) is a stiffer material in the loading direction than the first layer. The strip element may be loaded so it or its edge does not substantially bend in the direction of movement of the facing surface. To optionally reduce the effect of abrasion: an inner mantel surface is treated by grain blasting, thermal injection coating, chemical or electro-chemical precipitation coating and/or polymer-based coating; and/or a lubricant or additive is fed between surfaces abrading against each other; and/or at least part of suction holes in a wall of the mantel are broached (71).

摘要： Method and arrangement for measuring the position of the end shields of a paper, pulp, or board reel relative to the grab (1, 2) transporting it, when an end shield is attached to the grab (1, 2). During measurement, a detector (7) is moved along such a curve of a circle that can be assumed to intersect the curve of the circle described by the edge of the object. The angular position of the detector (7) is measured using the curve of the circle over which it travels and the intersection points (x1, z1; x2, z2) of the curve traveled by the detector (7) and the edge of the object are detected. The location of the center point (x0, z0) of the object is calculated on the basis of a) the radius of the circle traveled by the detector and the location (xm, zm) of the center point of the circle, b) the location (xt, zt) of the tool point, c) the assumed radius of the object, and d) the locations (x1, z1; x2 z2) of the detected intersection points. Finally, the position of the center point (x0, z0) of the object in the set of co-ordinates of the grab is calculated.

摘要： The lateral position of a web or fabric edge 11 in a paper machine is determined using an ultrasonic sensor. The ultrasonic sensor has a detector head 42, with an air channel system which opens to the vicinity of the head for forming an air knife which prevents accumulation of dirt on the head. The protective cover 35 has an air guide 43 extending further than the detector head 42, with air flowing thereabove from inside the protective cover 35 through an opening 36. The end component is on top of the protective cover allowing air to flow from the opening between the air guide and the end component to a detent, which turns the direction of the air flow. This provides efficient cleaning without disturbing, however, the operation of the ultrasonic sensor.
