Spinning machine

Abstract

A spinning machine in which a spinning member is disposed, the spinning member having a nozzle block 11 in which air injection holes are drilled, a hollow guide shaft 17, a fiber introduction hole 101 opened at a tip side of the hollow guide shaft 17, and a fiber guide member 106 that guides fibers to the tip of the hollow guide shaft 17, wherein, first, a separating projecting portion 105 is formed in a fiber contact surface of the fiber introduction hole 101 to define a plurality of passages 103S, 103Z having different fiber introduction directions with respect to said fiber guide member 106 (Fig 2).

Description

technical field [0001] The invention relates to a spinning machine which utilizes swirling airflow to produce spun yarn. Background technique [0002] First, see Figure 7 The overall structure of a conventional spinning machine is described. [0003] Reference numeral F denotes a fiber bundle which is an aggregate of short fibers such as sliver contained in the can 1 . Reference numeral D denotes a 4-wire type drawing device consisting of a rear roller 2, a third roller 3, a second roller 4 around which a spindle driving belt 4a is wound, and a front roller 5, which is shown as an example . Reference numeral S denotes a spinning element, which will be described later, and reference numeral 6 denotes a yarn supply member, which is composed of a nip roller 6a and a delivery roller 6b. Reference sign P designates a take-up bobbin formed around a bobbin 7 supported in a bobbin holder (not shown in the figure). The rotationally driven friction roller 8 abuts against the surf...
