Embodiment Construction

[0033] figure 1 A cutting device 1 , a liquid delivery device 2 and a fiber suspending device 3 are shown. The fibers cut into short fibers in the cutting device 1 are flushed with liquid into the liquid delivery device 2 and sent to the fiber suspension device 3 . According to the prior art, the liquid delivery device 2 is configured as a tank which is not completely filled with liquid. The fiber strands are formed in the fiber suspension device 3 and in a subsequent stage the fiber strands are cleaned and reprocessed (not shown).

[0034] According to a preferred embodiment of the device according to the invention, as shown in FIG. 2 , the liquid delivery device 2 has a siphon-shaped part 4 which is configured with two branches 5 , 6 . Between the two branches of substantially equal length there is provided a substantially horizontally extending intermediate portion 7 whose length is equal to a multiple of the length of the downwardly extending branch 5 .

Abstract

The invention relates to a device for producing cellulose staple fibers, comprising a cutting device (1) for cutting cellulose filaments into staple fibers, and a liquid delivery device (2) for conveying the staple fibers. The device according to the invention is characterized in that the liquid delivery device (2) has a part in the form of a siphon (4).

Description

technical field [0001] The present invention relates to a method and an apparatus for producing cellulose staple fibers. Background technique [0002] In the conventional manufacturing method of cellulose staple fibers, freshly spun cellulose filaments are chopped into staple fibers in a cutter. Short fibers are transported onwards from the cutter outlet and processed. For example, short fibers are suspended into fiber strands in the fiber suspending device. Subsequently, the fiber strands are subjected to further processing steps such as washing and finishing operations. [0003] The device known from the prior art comprises a cutting device for cutting the filaments into staple fibers and a liquid delivery device for conveying the staple fibers. [0004] According to the prior art, the liquid conveying device is usually configured as a groove whose origin is arranged eg below the shut-off device. A bundle of filaments to be cut enters the cutting device and is cut ther...
