Problems solved by technology

Therefore, the initial spinning process is generally carried out at the output speed of normal spinning, and its disadvantage is that the initial spinning process is repeated many times.
[0006] The aforementioned problems cannot be overcome by existing spinning technologies such as those disclosed in DE 199 26 492 A1 and DE 40 36 119 C2

Embodiment Construction

[0025] The spinning position 1 shown in FIG. 1 has a housing 2 in which an air nozzle body 3 is held. The fiber sliver 6 fed by the input rollers 4 , 5 enters the feed opening 7 of the casing 2 and passes through the fiber sliver delivery channel 8 and the control element 9 to the inlet 10 of the hollow ingot. The air nozzles 12 inject air into the region of the inlet 10 of the spindle 11 , thus forming an air flow circulating around the fiber sliver 6 and the spindle head 13 , which exerts a twisting effect on the fiber sliver 6 . The free fiber ends 14 of the fiber strip 6 are wound onto the fiber strip 6 and the spindle head 13 . The injection action of the air injected by the air nozzle 12 and the fiber sliver 6 entering the feed opening 7 at a high speed create an air gap 15 in the fiber sliver conveying channel 8 or between the fiber sliver channel wall and the fiber sliver 6. Airflow 30. The air flow 30 goes to the spindle 13 according to the longitudinal movement of ...

Abstract

The invention provides a spinning apparatus for producing a yarn spun by means of a circulating air flow comprising a housing with an inlet opening for receiving sliver, at least one sliver guidance element mounted on back of the inlet opening and and a hollow spindle through which a formed yarn is withdrawn. The spindle has a conical spindle head, and openings in the area of spindle inlet for injecting circulating air flow into the housing. The circulating air flow comprises a linear airflow component in yarn traveling direction, and a twisting airflow component in helical orientation about the yarn for wrapping free fiber ends of sliver helically around the spindle head to be subsequently wrapped around the yarn at an acute angle with respect to the yarn traveling direction as the yarn is drawn off through the spindle, which is characterized in having a control device (23, 60, 68) and an adjustment device (17, 54, 66) adjusts the linear flow component as a function of yarn withdrawal speed, and controls a helical wrapping angle of fiber ends (14, 48) around the spindle (13, 49) and the acute angle of wrapping the fibers around the yarn.The control device (17, 54, 66) controls the spinning start process and setting(s) for normal spinning operations.

Description

technical field [0001] The invention relates to a spinning device for producing a spun yarn by means of a circular air flow. Background technique [0002] DE 199 26 492 A1 discloses a device for producing a spun yarn by means of a circulating air flow. The sliver to be spun is introduced into a spinneret pack and passes through a tow collector. The collector has mutually spaced fiber control elements which allow free passage of a core fiber bundle. At the entrance to the next spindle, the fiber sliver is in an air flow that surrounds the fiber sliver. The free fiber end of the sliver is looped by the circulating air flow at the spindle inlet to the tapered spindle head. When the fiber sliver is drawn into the hollow spindle, these fiber ends form a helical shape around the fiber sliver, forming so-called wrapped fibers, so that the fiber sliver produces a yarn and is output from the hollow spindle. [0003] DE 40 36 119 C2 also describes a device for producing spun yarn ...
