Publication number: 20230321858Abstract: A system (50) for controlling performance of a slitter-winder (25) and/or a fiber web production line (100) has an advisor unit (34, 36, 37) with a processor and a memory including computer program code, configured to cause the advisor unit (34, 36,37) to generate and transmit signals as first control data to the slitter-winder (25) and/or as second control data to the fiber web production line (100) based on information data received from the slitter-winder (25) and the fiber web production line (100) to control performance of the slitter-winder (25) and/or the fiber web production line (100). Performance of a slitter-winder (25) and/or a fiber web production line is controlled by receiving information data from the slitter-winder and the fiber web production line (100), processing the received information data according to a predetermined configuration, based on the processed data; generating signals according to the predetermined configuration to control the performance.Type: ApplicationFiled: April 7, 2023Publication date: October 12, 2023Applicant: Valmet Technologies OyInventors: Jaakko Haapanen, Marko Jorkama, Jari Kääriäinen, Marko Kääriäinen, Kenneth Åkerlund

Publication number: 20220396444Abstract: A method for joining ends of fiber webs with a device comprising a tool element with a gripping device and a traversing punching device. A run of the fiber web from the emptying parent roll is moved to a joining position at the tool element. The trailing end of the parent roll fiber web is cut upstream from the joining position and the fiber web is attached to the tool element by a gripping device of the tool element. An end of a new roll fiber web is guided to contact with and to an overlapping position with the trailing end of the parent roll fiber. The traversing punching device is moved across the width direction of the fiber webs and makes at least one joint cut and joins the fiber webs. The new fiber web is cut downstream from the joint, and then tension control is turned on.Type: ApplicationFiled: June 11, 2022Publication date: December 15, 2022Inventors: Jaakko HAAPANEN, Henry VIRTA, Kenneth ÅKERLUND

Patent number: 11332335Abstract: A reeling shaft transfer rail system has two parallel substantially horizontal or slightly sloped rails for supporting the ends (25) of a reeling shaft (20). Hoses are arranged on each of the transfer rails (15) and filled or drained to move and hold the reeling shaft (20). In a method of transferring reeling shafts on transfer rails, the reeling shafts (20) are transferred on two parallel, substantially horizontal or slightly downstream of a main transfer direction inclined transfer rails (15) for supporting each of the supporting ends (25) of a reeling shaft (20). The reeling shafts (20) are transferred or positioned in the reeling shaft transfer rail system (10) by pressurizing hoses (17) arranged on each of the transfer rails. The hoses are arranged so fluid added to or withdrawn from the hoses pushes or holds the reeling shaft (20) on the transfer rails (15).Type: GrantFiled: February 17, 2020Date of Patent: May 17, 2022Assignee: Valmet Technologies OyInventor: Jaakko Haapanen

Publication number: 20210155436Abstract: To minimize the cost of a fiber web due to the web, particularly a board web, being manufactured overly thick to compensate for loss of caliper in the reel-up, the web is made thicker just for the inner layers of what will become a parent roll. The caliper of the web is measured as or after it is unwound. A caliper curve of the parent roll as a function of the diameter of the parent roll is calculated as a function of the diameter of the parent roll and/or the customer roll. The fiber web is adjusted by changing running parameters of the production line: web speed i.e. production speed, headbox-flow, head-box consistency, coating weight of the coating paste or calender nip load.Type: ApplicationFiled: January 20, 2021Publication date: May 27, 2021Applicant: Valmet Technologies, Inc.Inventor: Jaakko Haapanen

Publication number: 20200407185Abstract: In a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction. Two cuts (C1, C2) are formed by the nozzles starting from the web edges moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts nozzle movement is stopped and after the return of the nozzles, cutting is restarted from the center toward the edges so the web W is cut by two cuts (C3, C4) forming a substantially V-shaped beginning end (V2) and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. Cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the web width.Type: ApplicationFiled: September 14, 2020Publication date: December 31, 2020Applicant: Valmet Technologies OyInventors: Jaakko Haapanen, Kimmo Penttilä, Vesa Riihelä, Kai Forssen

Patent number: 10800628Abstract: In a turn-up method for a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction in relation to the web travelling direction (S). Two cuts (C1, C2) are formed by two water jet nozzles starting from the edges of the web (W) and moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts the movement of the water jet nozzles is stopped and after the return movement of the water jet nozzles, cutting is started again from the center toward the edges so that the web W is cut by two cuts (C3, C4) and a substantially V-shaped beginning end (V2) to the web W is formed and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts.Type: GrantFiled: February 5, 2019Date of Patent: October 13, 2020Assignee: VALMET TECHNOLOGIES OYInventors: Jaakko Haapanen, Kimmo Penttilä, Vesa Riihelä, Kai Forssen

Patent number: 9169095Abstract: A method and apparatus for winding fiber webs, particularly paper and board webs, in which partial web rolls (R1, R2) are wound in a winding device having at least two winding stations (21, 22), where partial webs (W1, W2) are guided to rolls (R1, R2) via a nip between a winding roll(s) (12, 41, 42) and the partial web rolls (R1, R2). The partial webs (W1, W2) are guided on the surface of the winding roll(s) (12, 41, 42) before entering the nips creating a wrap angle (A1, A2) on the winding drum(s) (12, 41, 42). The wrap angles (A1, A2) of the partial webs onto the surface of the winding roll (12, 41, 42) is at least 120° and the wrap angle ratio, i.e. the relation of the larger wrap angle to the smaller wrap angle, is at least 1 and at most 1.25.Type: GrantFiled: April 15, 2013Date of Patent: October 27, 2015Assignee: Valmet Technologies, Inc.Inventors: Jaakko Haapanen, Henry Virta, Heikki Föhr
