[0067] [Structure of Traversing Device of First Embodiment]

[0068] Such as Figure 6 and Figure 7 As shown, the traverse device 10A of the first embodiment includes the first guide portion 11 and the second guide portion 12 , the support portion 19 , and the drive portion 15 . The traversing device 10A makes the dragon belt 45a (refer to image 3 ) and the dragon belt 55a (refer to Figure 4 ) reciprocatingly moves along the width direction A of the dragon belts 45a, 55a. That is, the traverse device 10A is provided for the first drafting unit 40 and the second drafting unit 50 adjacent in the width direction A, and the traverse device 10A moves the dragon belts 45a, 55a adjacent in the width direction A along the Move back and forth along the width direction A. Hereinafter, the middle bottom roller 43a and the dragon belt 45a are respectively referred to as the first draft roller 43a and the first dragon belt 45a, and the middle bottom roller 53a and the dragon belt 5...

Abstract

A traversing device includes a guide device configured to guide a guard belt and a driver configured to reciprocate the guide device along a width direction of the guard belt. The driver moves only one guide device or only two guide devices back and forth as the guide device.

Description

technical field [0001] The present disclosure relates to a traversing device, a drafting device and a spinning machine. Background technique [0002] In a spinning machine including a plurality of spinning units, each spinning unit has a drafting unit. Each drafting section includes a pair of dragon belts for drafting the fiber bundle. The dragon belt is easy to wear due to the contact of the fiber bundle, and it is a part that needs to be replaced. In a spinning machine, in order to prolong the replacement cycle of the tangential belt, a traverse device that changes the contact position of the fiber bundle with the tangential belt is sometimes used. The traversing device has, for example, a plurality of guides that guide the belt at each drafting unit; and a drive unit that reciprocates the guides along the width direction of the belt (for example, refer to JP 2011 -032618 Bulletin). [0003] In the spinning machine as described above, the belts of the drafting sections...
