Patent number: 7541560Abstract: A drying apparatus includes a thermal roll for contacting and heating aluminum web in a continuous sheet form. The thermal roll includes a roll surface, having a static friction coefficient ? defined by contact with the web. The static friction coefficient ? satisfies a condition of: t+V?G wherein G = ? · ? A ? 1 = ? · t · sin ? ( ? / 2 ) where t is tension applied to the web; G is roll retaining force with which the roll surface frictionally retains the web; V is thermal expansion force generated by thermal expansion of the web retained on the roll surface; ?A1 is pressing force caused by the tension to the web and applied to the roll surface by the web; ? is a wrap angle at which the web contacts the roll surface. Thus, distortion of the web can be prevented even with a great difference in the temperature from the thermal roll.Type: GrantFiled: December 23, 2003Date of Patent: June 2, 2009Assignee: Fujifilm CorporationInventors: Kenji Hayashi, Toru Onogawa

Patent number: 7169259Abstract: A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed.Type: GrantFiled: October 10, 2003Date of Patent: January 30, 2007Assignee: Metso Paper Karlstad ABInventor: Anders Tommy Lindén
