摘要： A layer-forming apparatus, particularly for the preparation of particle-board mats adapted to be compressed with heating in a platen or other press to form a coherent structure generally known as particle board, comprises a dispensing unit for metering the particulate matter onto a conveyor to form the layer and, between the dispensing unit and the conveyor, a classifying device for separating fine particles from coarser particles. The conveyor feeds a head which spreads the particles from the layer on a receiving surface. The receiving surface carries the mat and the head is designed to deposit the coarser particles of the layer from the conveyor either before or after the fine particles so that the fine particles form a facing zone on the bottom and/or top of the mat.

摘要： A board is formed by accumulating a mass of sugarcane rind fibers in a collection zone ahead of a horizontally reciprocable first-stage plunger that has a sweep face. The first-stage plunger is shifted horizontally toward a fiber compression zone to horizontally compact the sugarcane rind fibers and orient the fibers in vertical planes disposed substantially parallel to the sweep face. A second-stage plunger is shifted vertically downwardly from above the compression zone to push the horizontally compacted sugarcane rind fibers downwardly into a generally vertical passage means while vertically compressing the fibers. Consequently, the fibers are oriented in substantially horizontal planes to define a board segment comprised of sugarcane rind fibers having their axes disposed substantially parallel to the longitudinal axis of the board segment. The steps of accumulating, horizontally shifting, and vertically shifting are repeated to establish a column of abutting board segments in the extrusion passage. The board segments are heated at a heating station to melt natural resinous binder substances of the sugarcane rind fibers. Subsequently, the board segments are cooled at a setting station located below said heating station to reharden the natural resinous binder substances and bind together the board segments into a unitary board structure.
摘要翻译：通过在具有扫掠面的水平往复运动的第一级柱塞之前的收集区中积聚甘蔗皮纤维的大量而形成板。第一级柱塞水平地朝向纤维压缩区移动，以水平压缩甘蔗皮纤维，并将纤维定向在基本上平行于扫掠面设置的垂直平面中。第二级柱塞从压缩区上方垂直向下移动，以将水平压实的甘蔗皮纤维向下推入大致垂直的通道装置中同时垂直压缩纤维。因此，纤维在基本水平的平面中定向，以限定由甘蔗皮纤维组成的板段，其中它们的轴基本上平行于板段的纵向轴线设置。重复堆积，水平移动和垂直移动的步骤，以在挤出通道中建立一对邻接的板段。板段在加热站加热，以熔化甘蔗皮纤维的天然树脂粘合剂物质。随后，板段在位于加热站下方的设置台处冷却，以再生天然树脂粘合剂物质并将板段结合在一体的板结构中。

摘要： A mat formed of a mixture of board particles and a bonding agent is conveyed to oppositely rotating rollers which compress said mat to a desired thickness as the mat passes therethrough. A conveyor associated with the rollers is provided for carrying the compressed mat between a pair of platens mounted in a fixed relationship with respect to the continuously moving mat. As it passes between the platens, the mat is supported by a fluid bearing and is exposed to heat to cure the bonding agent. The platens are internally divided into separate subcompartments. The pressure in these subcompartments is regulated such that the mat is subjected to controlled pressures as it moves past the platens.

摘要： Fire retardant reconstituted cellulosic products are produced having fire retardancy substantially equal to conventional fire retardant products by impregnation of a portion of bark with a fire retardant and mixing said impregnated bark portion with another portion of bark which is untreated with a fire retardant. Additionally, a portion of wood chips is impregnated with a fire retardant and mixed with another portion of wood chips untreated with a fire retardant. Subsequently, the combined portions of bark and wood chips are formed into a three layer composite particleboard, having a bark core and wood chip surface, by pressing and heating.

摘要： A process for making a particle board of substantial continuous thickness utilizing any of a wide assortment of comminuted lignocellulosic materials. The particle board is prepared by mixing dried lignocellulosic particles with one or more thermosetting or thermoplastic adhesive binders in predetermined proportions, and placing a measured amount of the resultant mixture in an elongate mold where it is bonded together under the influence of pressure and heat. The mold includes a movable pressure plate forming the top of an enclosure within which the material is compressed to a predetermined thickness by pressure applied to the exterior of the plate. The thickness of the compressed mixture is substantial, so as to enable the production of particle board pieces having sufficient continuous solid thickness that they may be used for such applications as dimension lumber or railroad ties, or may be sawed into multiple thinner pieces for other applications such as siding. After the mixture in the mold has been compressed to the predetermined thickness, fasteners are attached for retaining the pressure plate in its compressed position. Thereafter the mold is taken from the press and transferred to an oven where its contents, still under pressure from the retained pressure plate, are baked or cured for an extended period of time and then allowed to cool, after which the pressure plate is removed from the mold permitting the removal of the resultant bonded particle board product.
摘要翻译：使用粉碎的木质纤维素材料中的任一种制造具有基本连续厚度的刨花板的方法。通过将干燥的木质纤维素颗粒与一种或多种热固性或热塑性粘合剂粘合剂以预定比例混合并将测量量的所得混合物放置在细长模具中并在压力和热力的影响下将其结合在一起来制备颗粒板。模具包括形成外壳顶部的可移动压板，通过施加到板的外部的压力将材料压缩到预定厚度。压缩混合物的厚度是实质的，以便能够生产具有足够的连续固体厚度的颗粒板片，它们可以用于诸如尺寸木材或铁路连接件的应用，或者可以被锯成多个较薄的片以用于其它应用如壁板。在将模具中的混合物压缩到预定厚度之后，紧固件被固定以将压板保持在其压缩位置。此后，将模具从压机中取出并转移到烘箱中，其中仍然在压力下保持的压力板的内容物长时间地被烘烤或固化，然后冷却，然后将压板从该模具允许除去所得到的粘合刨花板产品。
