    摘要： From about 50 to about 90% by weight of fibers, in particular wood fibers, and/or pellets made from cellulose or from wood, are mixed with from about 10 to about 50% by weight of a hot-curing resin, each of the percentages by weight being based on the total weight of the mixture. Instead of a single resin it is also possible to use a mixture made from two or more hot-curing resins. The mixture made from fibers and/or pellets and resin is kneaded and homogenized and then passed on to an extruder which has various heating zones in which the mixture is heated. Care has to be taken here that the maximum temperature, arising at the extruder exit, does not exceed about 120° C., since above this temperature the resin(s) begin(s) to cure. The mixture, not entirely cured, is extruded as a homogeneous composition and introduced into a calender line in which pressure is exerted on the composition to an extent which gives a preform mat, the shape of which is stabilized, and which is then removed for further processing or storage.

    摘要翻译： 约50至约90重量％的纤维，特别是木纤维和/或由纤维素或木材制成的颗粒与约10至约50重量％的热固化树脂混合，每个 重量百分比是基于混合物的总重量。 代替单一树脂，也可以使用由两种或更多种热固化树脂制成的混合物。 将由纤维和/或丸粒和树脂制成的混合物捏合并均化，然后通入具有加热混合物的各种加热区域的挤出机。 必须注意，挤出机出口处产生的最高温度不超过约120℃，因为在该温度之上，树脂开始固化。 将未完全固化的混合物作为均匀组合物挤出并引入压延管线中，其中压力施加在组合物上至达预制垫的程度，该预制垫的形状是稳定的，然后将其再除去 加工或储存。

    摘要： A cast part, for example, for use as an internal coating of a vehicle. The cast part has a bearing layer, which is compressed and made of natural fibers bound together by a binding agent. A decorative layer is disposed on an upper surface of the bearing layer and on a lower surface of the bearing layer, a sealing layer, on which functional elements are molded in the form of fixing clips and reinforcing ribs is disposed. The case part is made according to a process consisting in compressing a natural fiber matting containing a binding agent into the bearing layer having either a plane surface or a contour and, in a second forming step, shaping the decorative material located in a upper half of a forming tool as well as a thermoplastic material applied to a lower half of the forming tool for forming the sealing layer and the functional element formed therefrom. The cast part is highly resistant with undiminished aesthetic and tactile features of the decorative material, is not moisture-sensitive and does not smell.

    摘要： A method for molding parts in a thermoplastic molding system comprised of a thermoplastic material delivery station, and two or more clam shell molds mounted on a rotating frame, each clam shell mold comprised of a mounted die half and a hinged die half connected by a hinge directly or indirectly to the mounted die half, said die halves in a closed position forming a mold cavity, the method comprising the steps of (a) rotating the rotating frame to move the die halves in an open position past a thermoplastic material deliver station; (b) delivering thermoplastic material to at least one die half of a clam shell mold at the thermoplastic material delivery station; (c) closing the die halves as the claim shell mold rotates past the thermoplastic material delivery station by rotating the hinged die half on its hinge onto to the mounted die half to form a mold cavity; (d) cooling the clam shell mold as it continues to rotate on the rotating frame; and (e) opening the clam shell mold by rotating the hinged die half on its hinge and removing a part formed in the mold cavity.

    摘要： A sealing system and sealing composition are provided for inflatable articles containing air under pressure. The sealing composition includes particles or particulates of shapes having sharp corners thereon which tend to dig into the article around the opening and wedge themselves therein. The sealing composition also includes fibers, at least some of which are fibrillated. The fibers tend to wrap around the particles and further plug the leak opening. The particles and the fibers are in a liquid carrier which also tends to form a bond of the particles and fibers in the leak opening. The particles in the composition are of particular ranges of sizes for different articles, the larger particles being used in larger articles, such as large tires for construction machines, for example.
