Embodiment Construction

[0040] Use the following Figure 1 to Figure 15 Examples of the present invention will be described, but the present invention is not limited to the examples described below unless the gist of the present invention is deviated from.

[0041] First, the overall configuration of the spinning device will be described using FIG. 12 . In Fig. 12, V is the sliver supplied to the drafting device D through the yarn guide G. The second roller d3 and the front roller d4 form. In the drafting device D, the sliver V to be drafted is supplied to the spinning unit U described later, and after the yarn Y is formed by the spinning unit U, the yarn Y passes through the yarn composed of the nip roller h1 and the delivery roller h2. The yarn feeding device H, the loose tube T configured as a suction tube, the yarn clearer Z, etc., are wound on the winder w3 supported on the cradle w2 driven by the friction roller w1 of the winding section W. In addition, as described above, the spinning mecha...

Abstract

A spinning apparatus for producing yarn with soft contact feeling without influence on its strength is composed of a nozzle unit for generating cyclone airflow and non-rotary hollow guide axle with through yarn hole with non-circular cross-section in front end. Said cyclone airflow acts on the front end of said hollow guide axle.

Description

technical field [0001] The present invention relates to a spinning device for twisting the fibers constituting the yarn sent out from a drafting device by a spinning member composed of a nozzle portion generating a swirling air flow and a non-rotating hollow guide shaft member to produce yarn (Department of Textiles). Background technique [0002] A known spinning device is composed of a nozzle member generating a swirling airflow and a non-rotating guide shaft member having a yarn insertion hole. The swirling airflow generated by the nozzle member is applied to the front end of the hollow guide shaft member to perform spinning. . In such a spinning device, reversed fibers are generated at the front end of the hollow guide shaft member, and the reversed fibers are rotated at the front end of the hollow guide shaft member by the swirling airflow caused by the nozzle member. That is, the front end portion of the hollow guide shaft member becomes a contact area of ​​the inver...
