Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method for producing low medium or high density , fibre panels through hot compression of a fibre panel composed of glued fibres. According to said fibre production method vapour overpressure is used , to soften chips which are then shredded to form fibres. Said fibres are transported, with the vapour pressure, trough a blow duct in order to enter a , tubular drier, and are transferred after drying to a dispersion machine or the like. To reduce the binder consumption the final section of said tubular , drier is built as a glue-wetting area wherein the transport speed of the fibre mixture is reduced due to an enlargement of the flow section of said tubular …
