Embodiment Construction
[0032] The invention is explained in more detail below on the basis of a single schematic diagram, which shows a schematic side view of a draw frame, which is more precisely an example of a spinning frame or spinning preparation machine. According to the example a plurality of substantially untwisted adjacent fiber slivers FB are shown in the draw frame (the fiber sliver here is only produced in the front), it is also possible that only one fiber sliver FB is fed to the draw frame, which is made of It is obtained directly from a card or comber in the front. A bell mouth 12 for compacting the fiber sliver is arranged at the inlet of the draw frame. Alternatively, another compaction device may be applied. In addition, the fiber sliver passes through the component scanning devices 2, 3 of the input sensor 1, at this time a plurality of individual fiber slivers FB have become a compressed fiber sliver FB', and enter the drafting device 4 of the core part of the draw frame.
