Abstract: The present invention relates to an arrangement (1) for measuring the temperature of a web. The arrangement (1) comprises a plurality of sensors (3) for contactless measuring of the temperature, an elongated housing (5) intended for extending essentially along a transverse direction (T) which is transverse to the direction of movement of a web. The sensors (3) are arranged in a chamber (6) within the housing (5) and spread along the front side (7a) of the housing (5). Each sensor (3) is connected to a data bus (9) for providing information of the measured temperature to other systems and/or apparatuses. The sensors (3) are attached to a support structure (19) having at least one rotatable shaft (23) in the interior of the housing (7), and wherein the shaft (23) is arranged to rotate the support structure (19) such that the sensors (3) are displaced to a calibration and/or protection position away from the openings (11) for calibration and/or protection of the sensors (3). The invention also relates to a method for measuring the temperature of a web, a computer program, a computer readable medium and a control unit.

Abstract: A method for producing a web of fibrous material includes the steps of:



(a) low-water processing of cellulose-containing fibers into individual fibers and/or fiber bundles;
(b) forming of the individual fibers and/or the fiber bundles in an air stream into a planar laid fibrous structure using a dry forming method;
(c) moistening the individual fibers and/or the fiber bundles by way of a fluid;
(d) solidifying the planar laid fibrous structure by applying pressure in a press nip; and
(e) heating the individual fibers and/or the fiber bundles upstream from the step of solidifying (d) so as to increase a temperature of the individual fibers and/or the fiber bundles in the step of solidifying (d).
