Abstract: The invention relates to a method of making a paper or paper board, in which method cut pulp is prepared by cut-ting basic cellulosic fiber pulp at the consistency of at least 25 % so that the average fiber length of the basic pulp is decreased by more than 25 % and the SR number of the cut pulp is at most 20 % higher than that of the basic pulp, and the cut pulp is used as a raw material in the preparation of a stock.

Abstract: Den föreliggande uppfinningen avser ett förfarande för framställning av cellulosakarbamat, vilket förfarande innefattar följande steg: tillhandahållande av en aldrig torkad massa, tillsats av urea och blandning av nämnda massa med nämnda urea, mekanisk behandling av nämnda blandning, torkning av blandningen, samt uppvärmning av den förhållandevis torra blandningen för att på så sätt tillhandahålla ett cellulosakarbamat. Den föreliggande uppfinningen avser även ett cellulosakarbamat som kan erhållas genom nämnda förfarande, användning av nämnda cellulosakarbamat samt en spinnlösning innefattande nämnda cellulosakarbamat.

Abstract: The present invention relates to a method for manufacturing cellulose carbamate which method comprises the following steps: providing a never-dried pulp, adding urea and mixing said pulp with said urea, mechanically treating said mixture, drying the mixture, and heating the relatively dry mixture thus providing a cellulose carbamate. The present invention also relates to a cellulose carbamate obtainable by said method, use of said cellulose carbamate and a dope comprising said cellulose carbamate.

Abstract: An in-line web material processing machine (1) for producing a coated material is disclosed. The processing machine comprises a process vacuum chamber (31) housing an unwinder reel holder for holding a first supply roll (51) of web material (2) to be processed and a vacuum coating unit (52) for deposing a coating on the web material. A loading vacuum chamber (32) housing a second supply roll of web material to be processed is provided, with an inlet closure (321) arranged between the process vacuum chamber (31) and the loading vacuum chamber (32). The inlet closure (321) is arranged to be moved between a closed state, in which the vacuum chambers are separated from each other, and an open state, in which access is provided between the vacuum chambers. An automatic reel change system (4) is operable to move the second supply roll of web material from the loading vacuum chamber (32) to the process vacuum chamber (31) under vacuum when the inlet closure (321) is in the open state and to change a supply roll (51) on the unwinder reel holder from the first supply roll to the second supply roll under vacuum.

Abstract: Förfarande för att framställa en renad ligninprodukt genom en enzymatisk behandling, varvid förfarandet innefattar stegen: att tillhandahålla en blandning innefattande lignin och att ställa in och/eller bibehålla ett pH-värde som är ett optimalt pH-värde för den enzymatiska behandlingen, att tillsätta minst ett enzym till nämnda blandning, varvid det minst ett enzymet är inriktat på att hydrolysera kolhydrater som föreligger i nämnda blandning, att ställa in och/eller bibehålla blandningen till/vid en optimal arbetstemperatur under en optimal reaktionstidsperiod för den enzymatiska behandlingen, samt att avsluta den enzymatiska behandlingen.
