Abstract

<PICT:0999696/C3/1> A rigid mouldable fibrous panel is produced by the steps of depositing upon a moving foraminous conveyer 14 an airborne mixture 10 of fibres and resinous binder material to form a mat having a density of from 1 to 3 lbs./cu. ft., preferably removing the uneven surface layers of the fibrous web by means of a scalping roll 13, compressing the remaining mat to a density of 4 to 10 lbs./cu. ft., by rollers 17, 18 subjecting the mat to a hot environment, e.g. by means of steam chambers 22, 28 thereby adjusting the moisture content to between 8 and 15% and bringing the temperature to within the range of 90 DEG to 200 DEG F., separating the heated mat from the conveyer 14 and compressing the mat to a structure of uniform thickness and density of at least 30 lbs./cu. ft. by means of rolls 32, 34 which apply a nip pressure of from 100 to 500 pounds per lineal inch; the panel is then dried and cooled by a heater 48 and suction chambers 44, 52. The fibres used are preferably wood-fibres though other organic or inorganic fibres may be combined therewith. The resinous binder may be thermoplastic, thermosetting or a combination thereof in proportions of 1-15 parts thermosetting resin and 5-25 parts of thermoplastic resin expressed as parts per cent by weight of the weight of the dry panel. Typical binder compositions include phenol formaldehyde, wood rosin, polyvinyl acetate, paraffin wax and neoprene.
