The drum is provided internally with means for fluidizing the injected fibers simultaneously, enabling higher production capacity and an increased distribution quality of the fibers. This former head has high capacity and an increased width, preferably over four meters, which avoids natural oscillations in the needle rollers as they are substituted by slotted air nozzles. The nozzles extend along a whole length of the drum and have adjustable nozzle lips to regulate the amount of air and direction of the air-flow blown through the perforations of the drum.

    Abstract: A former head allows processing of long fibers while achieving a carding action and a fibre distribution fulfilling high quality standards. The former head contains at least one needle roller. A mixture of air and fibers are injected above the horizontal plane of a center axis of the needle roller and directly onto a periphery of the needle roller. There may be a number of adjustable needle rollers. With a former head, where fibers and air are injected in a controlled and new way, it is possible to process longer fibers and maintain a high distribution quality. By using a number of adjustable needle rollers, the fibre material can go through a carding process during the distribution. This carding process is optimized by the needles injecting onto the periphery of the stationary needle roller as well as the subsequent contact with the adjustable needle rollers.

  • Patent number: 6709254
    Abstract: A support for a web forming machine which allows for vertical adjustment of a web forming belt with respect to at least one die head positioned above the web forming belt, and allows for tilting of the web forming belt. The support allows linear motion along a y-axis defined by a length of a guide shaft while preventing linear motion along a x-axis and a z-axis, e.g. the two axes perpendicular to the y-axis. Further, the support allows rotational or axial motion about the x-axis perpendicular to the y-axis but prevents rotational or axial motion about the y-axis and the z-axis.

  • Patent number: 6709613
    Abstract: A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.

  • Patent number: 6652789
    Abstract: The method and apparatus for forming composite wood products particularly composite veneer like products which may be intermediate products and laminated to form the final composite product. Strands are fed from a source of supply at a metered rate, entrained in an air stream and carried along a confined path between an entrainment zone and the source of supply. Strands are condensed onto a surface to form a veneer lay-up of at least one layer of strands on the forming surface and this veneer lay-up is carried from the path and deposited onto a collecting surface and later consolidated into a composite product. Entraining air and strands not forming veneer are separated in the supply station, the strands fall onto the supply of strands and energy is added to the separated entraining air and it is returned to the entraining zone.
