DEVICE FOR BOARD MANUFACTURE

摘要

A device for compressing and processing a material mat at the manufacture of board of lignocellulosic material, comprising rotary compression rolls. At least one of the compression rolls (2) is formed with a perforated shell surface (6) and an axial duct system (7) located inside of the shell surface. A slide shoe (8) abuts sealingly the end wall of the roll (2) for injection of the processing medium to the mat via the duct system (7) in a restricted sector (9) of the roll (2) where the mat is compressed.
