Abstract: A plurality of studs mount a doctor blade holder to a doctor back in a fiber web machine for slidable extraction of the doctor blade holder in the cross machine direction. Each stud (15) has a body (16) with a cylindrical center segment with a protruding nonround flange (17) formed as a single piece with the center segment. Opposed flats of the nonround flange of the body (16) may be engaged by the opposed parallel jaws of a conventional wrench allowing ready attachment of the studs to the doctor blade holder and subsequent installing within the channel of a rail which is mounted to the doctor back. A slide bar may be fixed to the doctor blade holder to extend out of the rail for engagement and extraction of the doctor blade holder.

Abstract: A conditioning doctor blade (11) for a fiber web machine contains a number of reinforcement fiber layers (24, 26) laminated on top of one another into an epoxy matrix (20), and silicon carbide particles (21), so that the reinforcement fiber layers (24, 26) have formed a fiber core (22) and surface fiber layers (23) on both sides of the fiber core (22). There is less epoxy matrix (20) in the fiber core (22) than in the surface fiber layers (23).

Abstract: Solid fuel in the form of particles is supplied to a pyrolyzer, and pyrolysis conditions are maintained in the pyrolyzer for separating condensable gaseous substances from the fuel. Heat required by the pyrolysis conditions is supplied at least partly with solid fluidized bed material which passes through the pyrolyzer simultaneously as it is fluidized by fluidizing gas in the pyrolyzer. Condensable gaseous substances separated from the fuel are conveyed from the pyrolyzer to a condenser, in which they are separated as so-called pyrolysis oil in liquid form, and solid fluidized bed material taken from the pyrolyzer and containing combustible pyrolysis residue originating from the fuel is circulated through a gasifier, in which product gas, which is burnt in a boiler or a kiln, is formed from the pyrolysis residue.

Abstract: A blade segment of a disc refiner for refining fibrous material has an inner circumference and an outer circumference as well as a first side edge and a second side edge which connect the inner circumference and the outer circumference. The side edges are curved, with one convex and the other concave. The segment has a refining surface with blade bars and grooves which define a pumping direction. The side edges of the blade segment curve in the vicinity of the inner circumference in the pumping direction, and in the vicinity of the outer circumference in a non-pumping direction.

Abstract: A coating device and method for coating a fiber web for applying coating color onto a fiber web has a nozzle unit with at least one nozzle part (10), a feeding chamber (11) and at least one equalizing chamber (13; 13′), a feed hole (12) between the feeding chamber (11) and the first equalizing chamber (13), and a nozzle slot (14′) from which the coating color is discharged through the nozzle slot (14′) outlet opening (15). A mixing chamber (20) between the outlet area of the feed hole (12) and the equalizing chamber (13) functions as a means for distributing uniformly the inhomogeneous coating color flow entering the equalizing chamber (13) from the feed hole (12). The coating from the feed hole is directed to a wall (22) of mixing chambers (20) which distribute uniformly the coating entering the equalizing chamber (13).

Abstract: A trailing end (14′) of a web in a web roll (14, 14.1) is secured to a surface of the web roll in a slitter-winder (10) by attachment articles (30) which extend over a trailing end of the web on the roll surface. Each attachment article has an adhesive surface positioned on a path of movement of the web roll, facing toward the roll, and, while the roll is moved, it is attached on the surface of the web roll. An arrangement (11) for securing a trailing end of a web to the roll in a slitter-winder (10) has a roll handling system (24) to move the rolls (14) via a path, and an adhesive article distribution system (28) positioned to attachment the article, in which the two systems co-operate so that, as the rolls are moved, the attachment article is attached on the surface of the web roll.

Abstract: A blade element (11) for a refiner (10) for refining fibrous material has a blade element body (12) and blade bars (13, 13a, 13b) and blade grooves (14, 14a, 14b) therebetween. Bottoms of the blade grooves (14, 14a, 14b) have, in the longitudinal direction (LD) of the blade grooves, a variable depth profile comprising alternating high points (14a′, 14b′) and low points (14a″, 14b″) so that there is a phase shift (X2) between the high points (14a′, 14b′) and the low points (14a″, 14b″) of the variable depth profiles of the bottoms of the adjacent blade grooves (14a, 14b). Also, a refiner (10) for refining fibrous material and a method for manufacturing the blade element (11) for the refiner (1).
