The present invention concerns a process for producing a paper or board product, which process comprises providing a furnish comprising fibers; subjecting a first portion (1) of the furnish to polymer treatment, in which polymers are added to the furnish in at least two steps; blending said polymer treated first portion with an untreated second portion (2) of the furnish; and dewatering the furnish on a wire to form a fiber web. By treating only a portion of the furnish, the strength of the resulting paper or board product is significantly improved whereas the bulk remains substantially unaffected. The invention also concerns a paper or board product produced according to the process.

The present invention concerns a device and method for measuring the surface quality of an object. The device includes a portable object inspection entity (12) including a chamber (18) having a top surface (20), a bottom surface (22), and at least one side wall (24) joining the bottom surface with the top surface, a light detecting unit (34) directed towards an object inspection opening (26) provided in the bottom surface (22) of the chamber, thereby defining a line of sight (36) of the light detecting unit stretching through the chamber and being perpendicular to the object inspection opening, and a set of light sources (32) placed regularly around the line of sight within the chamber, where the light sources are directed towards the line of sight, in parallel with the object inspection opening.
摘要:
Cutting device (1) for lengthwise cutting of a moving, flexible web (2) containing an initial knife pulley (4), a second knife pulley (6) and a cylinder (11) with a moving piston (13), said second knife pulley being adjustable relative to the first knife pulley subject to the compressive force from the piston to bring the edge of the second knife pulley (10) to work with the edge of the first knife pulley (9). According to the invention, the cutting device has a slide (14) that is situated between the second knife pulley and the cylinder, said slide being adjustable in the axial direction of the second knife pulley and connected to the piston to follow its movement, and in which slide the second knife pulley has been rotatively stored.
