Sheet manufacturing apparatus, recording sheet, and sheet manufacturing method

Abstract

A sheet manufacturing apparatus includes a web forming section that accumulates a feedstock containing fibers in a gas to form a second web, an arranging section that arranges a magnetic body on the second web while the second web is transported, and a processing section that processes the second web on which the magnetic body is arranged into a sheet.

What is claimed is: 
     
         1 . A sheet manufacturing apparatus comprising:
 a web forming section that accumulates a feedstock containing fibers in a gas to form a web;   an arranging section that arranges at least one magnetic body on the web while the web is transported; and   a processing section that processes the web on which the at least one magnetic body is arranged into a sheet.   
     
     
         2 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the arranging section arranges the at least one magnetic body at a fixed position with respect to a transport path of the web.   
     
     
         3 . The sheet manufacturing apparatus according to  claim 2 , wherein
 the at least one magnetic body has a longitudinal shape,
 the at least one magnetic body includes a plurality of magnetic bodies, and 
 the arranging section arranges the plurality of magnetic bodies such that directions of the magnetic bodies are three or more different directions. 
   
     
     
         4 . The sheet manufacturing apparatus according to  claim 3 , wherein
 the arranging section arranges the plurality of magnetic bodies including three magnetic bodies arranged such that directions of the three magnetic bodies are different from each other by 60°±5°.   
     
     
         5 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the arranging section arranges, as the at least one magnetic body, a magnetic wire rod of a predetermined length containing a magnetic body.   
     
     
         6 . The sheet manufacturing apparatus according to  claim 5 , wherein
 the arranging section includes a guide configured to pivot in a direction in which an angle of the guide changes relative to a transport direction of the web, and the arranging section arranges the magnetic wire rod along the guide.   
     
     
         7 . The sheet manufacturing apparatus according to  claim 1 , further comprising
 a cutting section that cuts the sheet processed by the processing section to have a predetermined length, wherein   the cutting section cuts the sheet at a position at which a contained proportion of the at least one magnetic body is less than 1.0 parts by weight with respect to 100 parts by weight of the sheet after the cutting.   
     
     
         8 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the feedstock containing fibers contains a resin which is melted by heating to bond the fibers, and   the processing section heats the web on which the at least one magnetic body is arranged to process the web into the sheet.   
     
     
         9 . The sheet manufacturing apparatus according to  claim 1 , further comprising
 a coating process section that adheres a coating material to the at least one magnetic body arranged on the web or the sheet.   
     
     
         10 . A recording sheet comprising:
 a sheet formed of a feedstock containing fibers; and   magnetic wire rods containing magnetic bodies arranged on the sheet, wherein   less than 1.0 parts by weight of the magnetic wire rods are contained with respect to 100 parts by weight of the sheet, and   the plurality of magnetic wire rods is arranged such that the magnetic wire rods face three or more directions different from each other.   
     
     
         11 . The recording sheet according to  claim 10 , wherein
 the plurality of magnetic wire rods is arranged such that directions of the magnetic wire rods are different from each other by 60°±5°.   
     
     
         12 . A sheet manufacturing method comprising:
 a web forming step of accumulating a feedstock containing fibers in a gas to form a web;   an arranging step of transporting the web and arranging a magnetic body on the web that is transported; and   a processing step of processing the web on which the magnetic body is arranged into a sheet.   
     
     
         13 . The sheet manufacturing method according to  claim 12 , further comprising
 a cutting step of cutting the sheet processed in the processing step to have a predetermined length, wherein   the cutting step cuts the sheet at a position at which a contained proportion of the magnetic body is less than 1.0 parts by weight with respect to 100 parts by weight of the sheet after the cutting.
