    摘要: Press racking, or lateral movement of the movable portions of a press, occurs in certain particleboard processes during heating and pressing of the panels. It is attributed to shingling of wood particles during the formation of a mat. To eliminate or reduce the movement of the press, the mat is subjected to rolling engagement by a relatively small diameter roll located between the forming apparatus and the press. The roll subjects the mat to a downward rolling pressure. The peripheral roll surface is in contact with the newly formed upper surface of the mat and has a linear speed and direction of movement identical to the speed and direction of movement of the mat support. A resulting wave action within the mat is caused by shear and displacement forces applied to the wood particles, such that the shingled nature of the mat is modified to reduce or eliminate resulting lateral movement of the press components.

    摘要: A layer-forming apparatus for making particle-board mats comprises a spreading head adapted to deposit particulate matter upon a mat-forming surface. The distributing head comprises an array of mutually parallel interdigitated disk rollers with the interfitting disks defining progressively increasing interstitial spaces as the particles move from one side of the roller array to the other side thereof.

    摘要: Resin treated lignocellulosic fibers are conveyed by a stream of air downwardly to a separator containing one or more doffing rolls, which rotate adjacent a perforated scroll assembly. At the side opposite the doffers the assembly is connected to a vacuum supply which draws dust and foreign particles out of the fibers as they fall downwardly through the separator and into a hopper located in the rear of a feeder assembly housing. From here the fibers are fed by endless belts or aprons to an expansion chamber formed in the rear of a condenser housing containing one above the other a pair of endless condensers or screens. The fibers cascade downwardly in the expansion chamber to a generally wedge-shaped air bridge formed at the inlet end of the space formed between the confronting runs of the condensers. This space is connected to a pair of suction fans so that the fibers are slightly compacted as they are sucked by the fans through the throat of the air bridge and deposited on the confronting runs of the screen condensers. These two runs travel continuously toward the discharge end of the housing to produce an endless mat of fibers at the output. The upper belt is also mounted for vertical adjustment to vary the thickness of the mat.

    摘要翻译: 树脂处理的木质纤维素纤维通过空气流向下输送到含有一个或多个落纱辊的分离器,该落下辊绕着多孔涡旋组件旋转。 在与道夫相反的一侧,组件连接到真空源,该真空源将灰尘和外来颗粒从纤维中向下排出并通过分离器并进入位于给料器组件壳体后部的料斗中。 从这里,纤维由环形皮带或围裙进料到形成在冷凝器壳体的后部的膨胀室,该冷凝器壳体包含一对上下的一对环形冷凝器或筛网。 纤维在膨胀室中向下瀑布成形成在形成在冷凝器的相对运行之间的空间的入口端处的大致楔形的空气桥。 该空间连接到一对吸风扇,使得纤维在被风扇吸入空气桥的喉部时被稍微压实并且沉积在屏幕冷凝器的相对运行上。 这两个运行连续地朝着壳体的排放端移动,以在输出端产生无穷的纤维垫。 上带还安装用于垂直调节以改变垫的厚度。

    摘要: Apparatus for spreading or scattering fiber or chip fleeces made up of a mixture of cuttings of extremely fine or superfine, fine, and coarser glue-covered chips for the subsequent press forming into fiberboards and the like. A mixture of chips is supplied to a fleece or particle carrier by gravity feed between sets of air emitting classifying registers. The upper portion of the classifying registers include oppositely facing air outlet openings which face the stream of chips and effect an initial classification by spreading some of the fine and superfine particles outwardly of the central stream. The lower part of the registers include openings facing oppositely to one another and away from the center line of the stream of particles and spaced from one another to permit passage therebetween of a central portion of the mixture without further modification. Baffle plates are also provided in preferred embodiments to assist in preventing further classification of the central stream in the lower regions of the registers. The baffle plates are vertically adjustable so as to accommodate varying conditions for desired varying thickness boards to be formed by the layers of particles passed through the distributing chamber containing the air classifying registers.

    摘要: A resin-fiber glass mixture is sprayed-up and partially cured to a flexible, non-tacky sheet molding compound for second stage curing to a solid, infusible resin in a heated mold. The mixture is sprayed-up into a relatively flat sheet of one layer or two or more separable layers or with a variable thickness, if desired, to conform to the profile of the part to be molded. The resin comprises a polyanhydride, such as the copolymer of maleic anhydride and an alpha-olefin, an olefinically unsaturated monooxirane compound such as glyeidyl methacrylate, and an olefin such as styrene.
