摘要： A fiber or chip board is made by first forming a mixture of a binder and particles having a relatively low moisture content that is substantially less than a relatively high moisture content that a finished board should have. This mixture is deposited as a mat on a movable substrate so that the mat is substantially at ambient temperature and has the relatively low moisture content. Then the mat is preheated with steam to raise its temperature and to increase its moisture content to the predetermined relatively high moisture content. The thus preheated mat, whose moisture content has been corrected, is then simultaneously heated and compressed to form it into a board.

摘要： Multi-ply paper board or sheet is produced by forming plies individually at ply-forming stations by dry-forming techniques, and then transferring the formed plies to a main forming surface to produce the multi-ply product. The plies are consolidated by hot moist pressing before being transferred.

摘要： A method and apparatus for making a multi-ply paper sheet wherein a first web is formed by wet-laying fibres and a second web is formed by dry-laying fibres, the two webs being combined to form a multi-ply sheet and wherein the dry-laid web is produced by depositing dry fibres on a supporting band and consolidating the web by hot moist pressing before transferring to the first wet-laid web.
