Papermaking method

Abstract

A papermaker includes a mesh having a plurality of protrusions used to screen water and fiber that has not been broken down from a pulp is also used to web the pulp into a pulp web, such that a plurality of holes is formed to extend through the pulp web. After squeezing and drying steps, a paper with a plurality of voids is formed. The voids are formed without subsequent cutting process, such that the amount of pulp used for making the paper is reduced, and the cost and labor are reduced. Alternatively, when a pulp is webbed by a conventional mesh into a pulp web, a mold having a plurality of protrusions may be used to press the pulp web, so as to form the voids in the pulp web. Thereby, voids are formed simultaneously with the paper.

1 . A papermaking process, comprising: 
 providing a pulp;    using a mesh for screening the pulp and webbing the pulp into a pulp web; and    forming a plurality of voids in the pulp web.    
   
   
       2 . The process of  claim 5 , wherein the step of forming the voids includes using a mesh having a plurality of protrusions formed thereon to screening and webbing the pulp.  
   
   
       3 . The process of  claim 5 , wherein the step of forming the voids includes using a mesh having a plurality of holes through which portions of the pulp are filtered.  
   
   
       4 . The process of  claim 5 , wherein the step of forming the voids includes using a mold that includes a plurality of protrusions to press on the pulp web.  
   
   
       5 . The process of  claim 5 , further comprising squeezing water from the pulp web and drying the pulp web after the step of forming the voids.  
   
   
       6 . The process of  claim 5 , wherein the step of providing the pulp comprises the steps of: 
 obtaining a wood log;    debarking the wood log;    chipping the debarked wood log;    digesting the debarked wood log;    rinsing the digested wood log;    bleaching the rinsed wood log;    cleaning the bleached wood log; and    beating the bleached wood log into the pulp.    
   
   
       7 . The process of  claim 10 , further comprising a step of rinsing the wood log before the beating step.  
   
   
       8 . The process of  claim 10 , further comprising a step of mixing the pulp with additives.  
   
   
       9 . A papermaker, comprising: 
 a mesh for webbing a pulp into a pulp web having a plurality of voids therein.    
   
   
       10 . The papermaker further of  claim 1 , wherein the mesh comprises a plurality of protrusions formed thereon.  
   
   
       11 . The papermaker of  claim 1 , wherein the mesh comprises a plurality of holes extending therethrough.  
   
   
       12 . A papermaker, comprising: 
 a mesh for webbing a pulp into a pulp web; and    a mold for pressing the pulp web to form a plurality of voids in the pulp web.
