Embodiment Construction

[0035] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In addition, the same reference numerals are attached to the same or corresponding parts in each figure, and overlapping descriptions are omitted.

[0036] Such as figure 1 As shown, the spinning machine 1 includes a plurality of spinning units 2 , piecing cart 3 , blower box 4 , and power box 5 . A plurality of spinning units 2 are arranged in a row, and each spinning unit 2 produces a yarn Y and winds it into a package P. The piecing cart 3 performs a piecing operation in the spinning unit 2 in which the yarn Y is cut. The blower box 4 accommodates an air supply source and the like for generating a suction flow, a whirling flow, and the like in each part of the spinning unit 2 . The power box 5 accommodates a power machine and the like for supplying power to each part of the spinning unit 2 .

Abstract

The invention provides a fiber bundle guider (80) guiding slivers (S) to rear rollers (61) in a drafting device. The fiber bundle guider (80) is provided with a cylindrical body (81) guiding slivers and a first positioning part (82) arranged at a specified position in the guiding direction of the silvers (S) of the body (81) and positioned along the guiding direction on a bearing part (90) supporting the body part (81) in the drafting device.

Description

technical field [0001] The invention relates to a fiber bundle guide, a drafting device and a spinning machine. Background technique [0002] Conventionally, it is known that a drafting device is provided with a plurality of roller pairs that draft a fiber bundle (including a sliver), a fiber bundle guide that guides the fiber bundle to a plurality of roller pairs, and a support portion that supports the fiber bundle guide. (Refer to, for example, Japanese Patent Application Publication No. 6-20474). [0003] In the above-mentioned drafting device, if the positional relationship between the most upstream roller pair and the fiber bundle guide in the fiber bundle guiding direction deviates, there will be consequent yarn produced by the drafted fiber bundle. There are concerns about the deterioration of the physical properties of the wire. Contents of the invention [0004] Therefore, an object of the present invention is to provide a fiber bundle guide capable of properly...
