Abstract (en)
[origin: EP1889702A2] Process for complete or layer-wise production of a mat from chips pressed by pressure and heat during the production of timber product plates comprises dispersing and sieving the chips using a roller bed and removing over-sized chips from the process, and exposing the remaining chips to a directed air flow followed by wind screening and a second sieving. The wind screening is performed using the air flow and a fine sieve. Over-sized chips undergo second sieving and any remaining over-sized chips are removed. The chips from the wind screening and the second sieving are used to make a mat or layers of a mat on a molded sheet. An independent claim is also included for a machine for complete or layer-wise production of a mat from chips pressed by pressure and heat during the production of timber product plates. Preferred Features: The second sieving is performed using a perforated sheet or wire net.
