Method of Machining Fibre Board

Abstract

What is disclosed is a method of machining a fibreboard, wherein the fibreboard, which may have a non-uniform content of moisture, is cut into at least two fibreboard sections. The fibreboard sections are then provided with complementary matching orientation determining joining means along their lateral edges. A first type of orientation determining joining means is provided on a relatively dry lateral edge of a first fibreboard section, while a second type of orientation determining joining means is provided on a relatively moist lateral edge of a second fibreboard section.

1 : A method comprising:
 splitting a fibreboard into at least two fibreboard sections;   forming a complementary joining means along the relatively dry lateral edge of a first fibreboard section; and   forming a complementary joining means along the relatively moist lateral edge of a second fibreboard section.   
   
   
       2 : The method of  claim 1 , wherein at least one fibreboard section is laterally rotated 180 degrees prior to the forming step. 
   
   
       3 : The method of  claim 1 , wherein at least one fibreboard section is axially rotated 180 degrees prior to the forming step. 
   
   
       4 : The method of  claim 1 , wherein the orientation determining joining means is a tongue. 
   
   
       5 : The method of  claim 1 , wherein the orientation determining joining means is a groove.
