    • An apparatus for and method of recycling the edge portion (202) of a chopped strand mat (200) are disclosed. The method includes the steps of trimming an edge portion of the chopped strand mat, transporting the edge portion to a shredder assembly (110), and shredding the edge portion into individual strands or filaments (204). The separated strands are introduced with new chopped strands into the chopped strand mat forming process. The apparatus for recycling the edge portion of the mat includes a shredder assembly for separating the edge portion into individual strands. The shredder assembly includes two pairs of rollers that engage the trimmed edge portion. The first (120, 122) and second (130, 132) pairs of rollers are driven at first and second rotational speeds, respectively. Preferably, the second speed is greater than the first speed. The mat is pinched (124, 134) between each pair of rollers and is thereby placed under tension due to the different rotational speeds. The tension applied to the mat breaks the resin bond between the strands in the mat, separating the mat into individual strands on the downstream side of the second pair of rollers. The individual strands are then transported to a forming hood (20) of the chopped strand mat forming apparatus and introduced into the chopped strand mat manufacturing process (10).

    • 公开了一种用于回收短切纤维垫(200)的边缘部分(202)的设备和方法。 该方法包括以下步骤:修剪短切纤维网的边缘部分,将边缘部分输送到切碎机组件(110),以及将边缘部分切碎​​成单独的股线或长丝(204)。 将分离的股线用新的切碎的线引入切碎的股线成型工艺中。 用于回收垫的边缘部分的设备包括用于将边缘部分分离成单独的股线的切碎机组件。 切碎机组件包括接合修剪边缘部分的两对辊。 分别以第一和第二转速驱动第一(120,122)和第二(130,132)对辊。 优选地,第二速度大于第一速度。 垫子在每对辊之间被挤压(124,134),由此由于不同的转速而被置于张力下。 施加到垫上的张力破坏垫子中的股线之间的树脂粘合,将垫子分成第二对辊子下游侧的单个股线。 然后将各股线输送到切断的股线成形装置的成形罩(20),并将其引入到短切丝束制造工艺(10)中。
