Publication number: 20080172903Abstract: According to the drying method and apparatus of the present invention, at first, the coated film on one end side of the support is more quickly dried than that on the other end side, because drying air is supplied from one end side of the support. Subsequently, the coated film on the other end side of the support is more quickly dried than that on one end side, because drying air is supplied from the other end side of the support. Accordingly, the method and the apparatus can diminish a difference between drying rates in on one end side and in the other end side of the long support, in the whole drying zone. Thus, the method and the apparatus can uniformly dry the support and inhibit the production of a dry spot.Type: ApplicationFiled: January 16, 2008Publication date: July 24, 2008Applicant: FUJIFILM CORPORATIONInventors: Kazuhiro SHIMODA, Kyohei YOSHIMURA, Nobuo HAMAMOTO

Patent number: 6775925Abstract: Apparatus and a method for the evaporative cooling of a web within a dryer in a compact manner. Excess fluid overspray is controlled, thereby avoiding problems with fluid depositing on internal surfaces of the dryer, which can cause mineral build-up and can result in web breaks or quality defects if fluid drips onto the web. More specifically, a water delivery system is used which directs a water mist to the web by appropriate design and placement of the spray nozzles. The quantity of water delivered to the web is regulated, and is preferably based upon web temperature. Excess mist is controlled by directing hot air to effectively vaporize the excess mist before it is able to contact the internal surfaces of the dryer enclosure and its internal components.Type: GrantFiled: April 14, 2003Date of Patent: August 17, 2004Assignee: Megtec Systems Inc.Inventors: Steven J.

Patent number: 6699365Abstract: This invention relates to a three-stream atomizing nozzle for use with a rewet shower. The nozzle has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream. The third stream is also a straight stream that wraps around the first straight stream and the second swirl. The nozzle also has a mixing chamber in which the three air streams are mixed together for the atomizing purpose. The nozzle can from the combination of the three air streams produce fine water droplets that are suitable for a paper rewet shower and more importantly creates a tailorable water mass profile. The mass profile can be tailored into a shape that is close to a square shape which is ideal for rewet showers as a square profile creates minimal coupling between adjacent zones.Type: GrantFiled: October 22, 2001Date of Patent: March 2, 2004Assignee: ABB Inc.Inventor: Shizhong Duan
