    • In an opening unit for open-end spinning machines, which comprises a housing and a roller lined with sawtooth wire and rotatably arranged in the housing for separating the fibers along their path from the inlet to the outlet of the opening unit, a dirt separation duct is provided in the housing and is maintained under a reduced pressure. In the wall of the housing adjacent at least one side of the dirt separation duct a parallelizing element is inserted which comprises a plurality of saw tooth wire sections arranged in a side-by-side relationship and serving to balance the adverse effect of the dirt separation duct on the parallel flow of fibers on their path through the opening unit.
    • 在用于开放式纺纱机的开口单元中,其包括壳体和衬有锯齿线的辊,并且可旋转地布置在壳体中,用于沿着其从开口单元的入口到出口的路径分离纤维,污物分离管道 设置在壳体中并保持在减压下。 在相邻于污物分离管道的至少一侧的壳体的壁中插入有平行化元件,其包括以并排关系布置的多个锯齿线段,用于平衡污物分离的不利影响 在纤维的平行流动通过开口单元的路径上的管道。
