Spinning preparation machine

The invention relates to a spinning preparation machine (1) for blending fibres, comprising a removal device (25) for removing air from the spinning preparation machine (1) and a filling device for filling the spinning preparation machine (1) with fibres, the spinning preparation machine (1) being designed as a slide mixer having at least two slides (2-5). The filling device has a fibrous material inlet (6) and a transport air outlet (8) with a transport air outlet line (9), and a distribution line (11) which leads from the fibrous material inlet (6) to the transport air outlet (8) via the at least two slideways (2-5). The distribution duct (11) is separated from the transport air outlet (8) by a perforated element (12) which is designed to have a convex shape when viewed in the direction of the transport air outlet (8). 本发明涉及一种用于混合纤维的纺纱制备机（1），该纺纱制备机包括用于从纺纱制备机（1）中移出空气的移出装置（25）以及用于用纤维填充纺纱制备机（1）的填充装置，其中，纺纱制备机（1）被设计为具有至少两个滑道（2-5）的滑道混合器。填充装置具有纤维材料入口（6）和运输空气出口（8）以及分配管道（11），该运输空气出口具有运输空气出口管道（9），该分配管道经由所述至少两个滑道（2-5）
