Patent number: 10052855Abstract: A laminating device for composite material includes a laser device, a hot roller assembly which has a first hot roller and a second hot roller, a cool roller assembly which has a first cool roller and a second cool roller, an axial roller-driving unit and a spring force-adjusting unit. The laser device provides a laser beam onto laminating surfaces of two separate composite materials prior to the hot roller assembly. The axial roller-driving unit drives the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to undergo relative movement in a first direction. The spring force-adjusting unit provides spring forcing to the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to ensure further the lamination of the two composite materials.Type: GrantFiled: December 28, 2015Date of Patent: August 21, 2018Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Teng-Yen Wang, Lung-Wu Chang, Chang-Chou Li, Yang-Cheng Lin

Patent number: 6402892Abstract: In a method at the end of the drying section of a paper machine, drying cylinders (1, 2) are arranged in two substantially horizontal cylinder rows, wherein the first drying cylinders (1) are placed substantially higher than the second drying cylinders (2). In the method, the web (W) to be dried is conveyed alternately between the cylinder rows of the drying cylinders (1, 2). Further in the method, the transfer of the web (W) between the drying cylinders (1, 2) is supported by a wire run arrangement, and the web is guided after the last drying cylinder (1, 2) of the drying section (A) by a transfer arrangement in between the rolls of a pair of rolls in the calender section (B) of the paper machine.Type: GrantFiled: May 22, 2000Date of Patent: June 11, 2002Assignee: Valmet CorporationInventors: Jukka Kilpiä, Robert Baril

Patent number: 6247398Abstract: A calender for manufacturing a material web. A frame is supported at the top and bottom. At least five rolls are mounted on the frame such that axes of the rolls lie in a substantially common plane extending substantially parallel to the frame. The common plane extends at an acute angle relative to a horizontal plane.Type: GrantFiled: July 15, 1999Date of Patent: June 19, 2001Assignee: Voith Sulzer Papiertechnik Patent GmbHInventors: Franz Kayser, Joachim Hinz, Mathias Helmus, Gerhard Stock

Patent number: 6073549Abstract: A process and an apparatus for the manufacture of SC-A paper having a high gloss and high smoothness, wherein the paper arriving from the paper machine is supplied on-line to a supercalender (multinip soft calender), and wherein the paper travels through a plurality of nips for achieving the desired gloss and smoothness properties. The paper web arriving from the paper machine and supplied on-line to a supercalender (multinip soft calender) is moistened with steam immediately prior to the first nip of the supercalender and is guided through the first nip before the increased moisture of the surface resulting from the application of steam has dropped below a predetermined value in the range of 12% to 25%.Type: GrantFiled: August 27, 1998Date of Patent: June 13, 2000Assignee: V.I.B. Apparatebau GmbHInventors: Stefan Winheim, Rudolf Mann

Patent number: 5836241Abstract: A heat transfer system in which a continuous web of material (13, 14) is carried past a hot plate surface (12) with one face of the web in contact therewith, and a series of fluid-filled vessels (15) above the web to apply a load on the upper surface thereof to maintain uniform contact between the web and the hot plate surface irrespective of any undulation thereof. A transport section to convey the web past the hot plate surface comprises upper and lower traction belts (16, 17) disposed entirely beyond the end of the hot plate surface (12) with a fixed plate (18) beneath the lower belt (17) and a series of fluid-filled vessels (19) above the upper belt (16) which serve to maintain adequate drive contact between the belts (16, 17) and the web (13, 14).Type: GrantFiled: March 5, 1996Date of Patent: November 17, 1998Assignee: SCM Container Machinery LimitedInventor: Peter Horton

Patent number: 5799572Abstract: A method of and apparatus (10) for compacting harvested crop or fiber (30) such as wool or hay; the method comprising applying a mechanical compacting force to the crop or fiber at the same time as or immediately after subjecting the crop or fiber to an elevated temperature above a base reference temperature and/or an elevated moisture content condition above a base reference moisture content condition whereby the crop or fiber (30) is compressed to a compressed state of predetermined density using less compacting force than would otherwise be the case. The method and apparatus can also be applied to control moisture content and certain other storage characteristics through utilization of compaction apparatus (10) on its own or in conjunction with a pre-processor (35) or post-processor (36) or both.Type: GrantFiled: August 11, 1997Date of Patent: September 1, 1998Assignee: Riyate Pty LimitedInventors: Kim Antony Campbell, Paul Thomas McCardell
