    • A forming box for use in dry forming of a mat of fibrous material, and a forming method. The forming box comprises a housing with an open bottom providing direct access for fibers onto an underlying forming wire and a vacuum box underneath said forming wire; an inlet for supplying fiber material into the inside of the housing; and a number of fiber separating rollers in one or more rows in the housing between the fiber inlet and the housing bottom. An endless belt screen is provided inside the housing having an upper run between two rows of spike rollers and a lower run closer to the open bottom of the forming box. Fiber clumps captured on the lower run of the belt screen are conveyed above fiber separating rollers and are released from the upper run of the belt screen into contact with the fiber separating rollers.
    • 用于干法成形纤维材料垫的成型箱,以及成形方法。 成型箱包括具有开口底部的壳体,其提供纤维直接进入下面的成形网和位于所述成形网下面的真空箱; 用于将纤维材料供应到壳体内部的入口; 以及在纤维入口和壳体底部之间的壳体中的一行或多行中的多个光纤分离辊。 在壳体内部设置环形带状屏幕,其具有在两排尖钉辊之间的上游距离,更靠近成形箱的开口底部的下部行程。 在带屏幕的下游捕获的纤维团在纤维分离辊上方传送,并从带状屏幕的上部流动释放与纤维分离辊接触。
