Embodiment Construction

[0032] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the description of the drawings, the same reference numerals are attached to the same or equivalent elements, and overlapping descriptions are omitted.

[0033] Such as figure 1 As shown, the spinning machine 1 includes a plurality of spinning units 2 , a piecing cart 3 , a doffing cart (not shown), a first end frame 4 , and a second end frame 5 . A plurality of spinning units 2 are arranged in a row. Each spinning unit 2 generates a yarn Y and winds it into a package P. The yarn joining cart 3 performs the yarn joining operation in the spinning unit 2 when the yarn Y is cut by the spinning unit 2 or the yarn Y is disconnected for some reason. The doffing trolley doesff the package P and supplies a new bobbin B to the spinning unit 2 when the package P is fully wound in a certain spinning unit 2 .

Abstract

The invention provides a tensioner, a drafting device and a spinning machine. Tensioner (40) has: roller (54a~54d), supporting dragon belt (18a); Support body (52), the bearing (56a~56d, 56a~56d, 58a~58d); and the main body (50), which extends along the rotation axis direction of the bottom roller (16a), and can be disassembled in such a way that the bearings (56a~56d, 58a~58d) are arranged along the drafting direction of the fiber bundle The supporting body (52) is firmly fixed.

Description

technical field [0001] The invention relates to a tensioner, a drafting device and a spinning machine. Background technique [0002] There are known spinning machines including a draft device for drafting a fiber bundle and a spinning device for manufacturing a spun yarn by twisting the drafted fiber bundle. In the drafting device, a plurality of roller pairs are arranged in the drafting direction of the fiber bundle. Between the bottom roller and the tensioner (Tensor Bar: tension bar) of a roller pair, a dragon belt for holding (clamping) and drafting the fiber bundle is erected. [0003] DE102005000990A describes a drafting device including a tensioner (Belt Bridge: belt bridge) in which five rotatable rollers are arranged. [0004] According to the tensioner of DE102005000990A, the friction between the tensioner and the dragon belt can be reduced when the dragon belt rotates. [0005] In such a drafting device, the gripping position (nipping position) of the fiber bun...
