    摘要： A machine and method of forming fiberglass mats. Chopped glass fibers are mixed with water in a slurry and a movable screen is passed, generally upwardly, through a slurry. As the screen is moved, its surface is uniformly coated with the glass fibers in a uniformly increasing depth, dependent upon the length of travel of the screen through the slurry. Longitudinally oriented and randomly oriented continuous strands are projected onto the fibers captured on the screen at different locations in order to provide the resultant mat with tear strength in all directions. The screen passes over a vacuum for removal of most of the water from the workpiece; subsequently, a binder is added to the workpiece and the continuous mat is passed through an oven for curing of the binder. The mat is then wound upon a spool for later transport to a location in which the mat can be processed into a final product.

    摘要翻译： 一种形成玻璃纤维垫的机器和方法。 切碎的玻璃纤维与浆料中的水混合，并且可移动的筛网通常通过浆料通过。 当筛网移动时，其表面以均匀增加的深度均匀地涂覆玻璃纤维，这取决于筛网通过浆料的行进长度。 将纵向取向和随机取向的连续股线投影到在不同位置捕获在筛网上的纤维上，以便在所有方向上提供所得到的垫片的撕裂强度。 屏幕通过真空以从工件中除去大部分水; 随后，将粘合剂加入到工件中，并使连续的垫通过烘箱以固化粘合剂。 垫子然后卷绕在卷轴上，以便以后运输到可以将垫子加工成最终产品的位置。
