Embodiment Construction

[0018] Next, the drafting device of the spinning machine of the present invention will be described in detail according to specific embodiments shown in the accompanying drawings. First, a spinning machine that can suitably use the present invention will be described. Such as Figure 5 and Figure 6 As shown, the spinning machine is a structure in which a plurality of spinning components U are arranged, and the sliver L is transported to the drafting device D by means of a cylindrical yarn guide (horn head) T, and the spun yarn Y is formed by the air spinning device Sp , the spun yarn Y is wound up on the winding section W by passing through components such as the nip roll Rn and the yarn clearer Z. Reference symbol P is a piecing device for piecing, which can travel below the inside of the spinning device along the longitudinal direction of the spinning device.

[0019] Figure 5 and Figure 6 This is a description of the steps of processing the sliver L into the spun ya...

Abstract

The provided drafting device (D) for textile machinery comprises: arranging a yarn limit and guide unit (1) on upper of drafting roller (Rb), and applying the unit (1) to up-and-down compress the yarn(L) into flat.

Description

technical field [0001] The present invention relates to a drafting device of a spinning machine, and more particularly to a drafting device of a spinning machine for the purpose of supplying a sliver in a flat shape to the drafting device and stabilizing the drafting of the drafting device. Background technique [0002] In conventional spinning machines, the sliver L supplied to the drafting device D is, for example, Figure 1B1 As shown, after being formed into a beam having a substantially circular cross-section by the horn head T, it is supplied to the most upstream rear rollers Rb2 and Rb3 in the drafting device D. In this way, when the sliver L is formed into a bundle with a substantially circular cross-section and then supplied between the back rollers Rb2 and Rb3, any unevenness such as twist or thickness of the sliver is directly supplied to the back rollers, which causes draft. One cause of stretch instability. [0003] [Patent Document 1] Japanese Patent No. 31836...
