APPLICATION OF SURFACE PATTERN DESIGNS TO WOOD-CEMENT SHEETS

摘要

A process is created for incorporating surface structures into wood-cement boards which are pressed during cement hardening in a batch press and then are kept in clamping apparatus in the pressed state for a substantial length of time. In the invention the wood-cement boards freed from their plates and after their storage in the clamping apparatus are fed to a calendering system of which the calendering rolls are provided with a surface structure, the wood-cement boards moving between the calender rolls and being provided by these with surface structures on one or on both sides.
