摘要： A process for forming a mineral wool, resin-bound acoustical insulating fiberboard product is described, which includes steps for mixing mineral wool fibers and powdered thermosetting binder, the introduction of the mixture into an air stream, and the directing of the entrained mixture into a mat-forming zone formed by converging upper and lower forming wires, the exhausting of air through the wires to build up layers of fiber and binder thereon and the consolidation and heating of the layers to form a fiberboard product, the amounts of air exhausted through the forming wires being adjusted so that a resin-enriched layer of predominantly fine fibers is initially deposited on the upper forming wire. A preferred embodiment is disclosed wherein an open mesh glass fabric is positioned between the lower forming wire and the layer of fibers and resins being formed thereover, said fabric acting as a carrier for the board-forming mat.

摘要： Process is disclosed which is suitable for high speed production of uniform, lightweight webs by air-laydown of textile fibers. A toothed disperser roll doffs the fibers into an air stream of high uniform velocity and low turbulence to form a thin fiber layer from which the fibers are deposited in web form on a moving screen. A curved disperser plate, shrouds a portion of the disperser roll up to the point of fiber doffing. By using a disperser plate with a rough surface, preferably one having lateral grooves, web uniformity is remarkably improved.

摘要： In dry forming a layer of fibers, the fibers are conveyed by carrier air to a distributor housing having a perforated bottom wall through which the fibers pass downwards on to a foraminous forming surface connected on its underside to a suction box. The invention ensures that the fibers pass from the distributor to the forming surface under the influence of suction and gravity alone so as to provide a layer of more uniform depth than hitherto obtained by dry forming.

摘要： To form a composite random fiber web containing long and short length fibers, the two types of fibers are fed simultaneously into the same lickerin but with the shorter fibers fed into the lickerin above the longer length fibers, that is, at a point spaced angularly in the direction of rotation of the lickerin in advance of the point at which the longer fibers are fed into the lickerin. The intermingled fibers are doffed from the lickerin by centrifugal force due to the high speed rotation of the lickerin and by an air stream traveling past the lickerin, and are conveyed by the air stream to a moving foraminate condenser on which they are laid down in random fashion. In one embodiment of the invention, two lickerins are provided and two sheets of short length wood pulp fibers are fed into each lickerin angularly in advance of but simultaneously with feed of a mat of longer length textile fibers into each lickerin. A divided air stream sweeps past the two lickerins to doff the fibers therefrom.

摘要： A method of aerodynamic formation of a fibrous layer and an apparatus for performing same are adapted for joint operation with a carding machine wherein fibres are doffed off the main drum of the carding machine in at least two points at different speeds and in different directions by means of doffer rollers rotated at different angular speeds in opposing directions. The fibres doffed in these two points are conveyed in separate air streams produced by rotary air blowers mounted internally of the respective condensers from the points of doffing toward these condensers. On the latter, the fibres from layers, and the orientation of the fibres in one layer are different from that in the other layer. The two layers thus formed are combined into a single common layer on a delivery conveyor which carries them away for subsequent treatment.

摘要： The invention relates to the production of homogeneous and structurally resistant sheets or mats of thermoplastic fibers, such as glass fibers, issuing from a rotary centrifuge above a traveling conveyor. The molten filaments, discharged in radial directions is substantially horizontal planes, are transformed into fibrous form by a downwardly directed annular attenuating gaseous blast, and the resulting annular curtain of fibers is guided through a shaping assembly comprising a tuyere having a circular inlet and an elongated rectangular outlet with substantially elliptical intermediate sections of increasing flatness therebetween in the direction of travel of the curtain of fibers. The flattened curtain of fibers then passes through a shaping member formed essentially of a pair of large trapezoidally-shaped plane surfaces of predetermined spacings therebetween to obtain critical cross-sectional areas at its inlet and outlet as well as at intermediate portions thereof, with convergent portions between said surfaces, as well as provisions for the introduction of air into the interior thereof, which aid in the conveyance of the fibers to the outlet of said shaping member in proximity to the conveyor, whereon they are deposited smoothly across substantially the entire width thereof without the formation of lumps or nodules.

摘要： A fibrous web of non-uniform, cross-sectional thickness is formed in a continuous manner by air laying fibrous material at a first station and then air laying additional fibrous material at a second station downstream from the first to overlap at least partially the fibrous material deposited at the first station. To provide and maintain a precise configuration for the thicker portion of the web, a pressure differential is maintained across the web being formed to cause the air to flow through the thicker portion of the web as well as the thinner portions of the web at the substantially same rate as it approaches the web.
