Patent number: 7316184Abstract: A dryer is used for drying a web of material. The dryer includes a passage duct for the material web. Drying takes place within this passage duct which includes at least one straight section. The dryer is disposed on a printing group which includes vertical web guidance. The passage duct straight section is essentially horizontal and receives the web of material delivered to it by the printing group. The passage duct is comprised of at least two sections through which the web of material travels in opposite directions.Type: GrantFiled: July 9, 2003Date of Patent: January 8, 2008Assignee: Koenig & Bauer AktiengesellschaftInventors: Georg Schneider, Wolfgang Otto Reder, Karl Erich Albert Schaschek

Patent number: 6425271Abstract: The invention discloses an apparatus for treating fabrics which comprises a first chamber for forming a reserve of infeed fabric, a second chamber for forming a reserve of outfeed fabric, first means for slowly infeeding the fabric into the first chamber, second means for slowly removing the fabric from the second chamber, a duct allowing for the passage therethrough of the fabric between the first chamber and the second chamber, fabric transport means capable of forward and backward operation which generates a forward and backward movement of the fabric between both chambers, and control means, operation of which causes inversion of the forward and backward movement, and collision members adapted to be impacted by the fabric, which move between a collision position and a free passage position in synchronism with the forward and backward movement of the fabric.Type: GrantFiled: May 11, 2000Date of Patent: July 30, 2002Assignee: Jaume Anglada Viñas S.A.Inventor: Jaime Anglada Viñas

Patent number: 6108942Abstract: A drying apparatus for sliced veneer sheets having a conveying system comprising two superposed conveyor belts lying one above the other which are guided over a drying path around guide members. The drying path includes both rectilinear and curvilinear sections and includes a three roller configuration for making a one hundred eighty degree turn in the drying path. The drying path is designed to provide for pressing of the veneer and to allow for the effects of shrinking of the veneer during the drying process.Type: GrantFiled: July 20, 1998Date of Patent: August 29, 2000Assignee: Fezer S.A.

Patent number: 6073369Abstract: A carriage mechanism for horizontally carrying a rectangular shaped substrate and a gas injection mechanism for jetting a gas toward both upper and lower surfaces of the carried rectangular shaped substrate are provided and an air from a gas injection port is jetted on the substrate toward a center portion from both ends of the substrate, wherein by means of the high pressured air jetted from the gas injection port of the gas injection mechanism, droplets are collected from both end surfaces of the substrate and collected at the center portion of the substrate where the air concentrates, and the collected droplets are blown away from the end surfaces of the substrate with the help of surface tension of the substrate also.Type: GrantFiled: March 27, 1998Date of Patent: June 13, 2000Assignee: NEC CorporationInventor: Satou Yasuyuki

Patent number: 5378377Abstract: Excess liquid is removed from a fast-moving thread, in that the latter is deflected, so that the liquid is hurled off, the hurled off liquid is removed from the thread, in that the thread is passed through a closed chamber, where a vacuum is produced in order to facilitate liquid evaporation and in that the thread is led through a narrow gap, so that the layer directly surrounding the thread and travelling therewith is peeled off. The combination of these drying effects constitutes one process stage. Advantageously, this process stage is performed several times in direct succession, so that in the case of a thread-protecting, small deflection angle a good thread drying can be achieved. The process is performed by an apparatus comprising several chambers (K.1-3) connected in series in the thread movement direction, the thread being deflected at the inlet and/or outlet with respect to each chamber by a deflection element (U.1-4) and passes through a narrow gap (S.1-). The chamber walls (20.Type: GrantFiled: July 23, 1993Date of Patent: January 3, 1995Assignee: Rieter Machine Works, Ltd.Inventor: Felix Graf
