Title: Belt for wet paper transportation
Inventor: INOUE KENJI
IPC: D21F3/04
Filed: 2003-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a belt for wet paper transportation which has both function of wet paper attachment and transportation and function of smoothly releasing the wet paper when the wet paper is transferred to the following process and elongates its service life.  <P>SOLUTION: The belt 10 for wet paper transportation comprises a base body 30, a wet paper side layer 11 and a machine side layer 12. The wet paper side layer 11 is composed of a polymer elastic part 50. A porous structure 20(20') is exposed to or projects from the surface of the wet paper side layer 11. In the porous structure 20(20') exposed to or projecting from the surface of the wet paper side layer 11, a part embedded in the polymer elastic part 50 exhibits high anchor effect by the holes of the polymer elastic structure 20(20'). Since the porous structure 20(20') itself is worn similarly like a resin therearound, the distribution state of the exposed or projecting porous structure hardly changes by abrasion in use.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
