Patent number: 11801612Abstract: A measuring device is releasably received within a winding core of a customer roll wound on a slitter-winder (10). The measuring device (20) is releasably fastened within the winding core by fastening element(s) (21) securing the device to the winding core (10) for rotation during winding of the fiber web around the winding core to form the customer roll. Eccentricity of the customer roll as it is wound is determined from movement, speed and/or acceleration data received from at least two sensors of the measuring device and data is stored for use in unwinding the fiber web from the customer roll and serving as control information. Tension variations in unwinding can thus be anticipated and premeditative steps taken to ensure smooth running of the fiber web in unwinding in further processing.Type: GrantFiled: October 19, 2021Date of Patent: October 31, 2023Assignee: Valmet Technologies OyInventor: Marko Jorkama

Patent number: 5909855Abstract: A method for winding a paper web in which the paper web is wound by a winder or equivalent winding apparatus onto a roll and the running speed of the winder is controlled based on the frequency of rotation of the roll so that when the frequency of rotation of the roll approaches a range of oscillation, i.e., a range of frequency of rotation of the roll in which intensive oscillation occurs, the running speed is lowered quickly so that the frequency of rotation of the roll is reduced to a level lower than the lower frequency of the range of oscillation. Thereafter, the running speed of the winder is increased so that the frequency of rotation of the roll remains substantially constant until, e.g., the running speed of the winder prior to the reduction thereof as the frequency of rotation of the roll approached the range of oscillation is reached.Type: GrantFiled: October 29, 1997Date of Patent: June 8, 1999Assignee: Valmet CorporationInventors: Marko Jorkama, Jarmo Makela
