Problems solved by technology

[0014] In this regard, if the width dimension of the brake disc 28 (especially the braking surface 38) is enlarged (that is, the area of ​​the braking surface 38 is widened), the plane of the braking surface 38 on the yarn 14 running side Degree (smoothness) becomes prone to deviation

Embodiment 1

[0048] refer to Figure 2 to Figure 5 , braking device 40 with Figure 18 The shown existing brake device 22 is the same, including: a brake main body 26 installed on the combination rod 24; The brake plate 28 on the front side of 26.

[0049] The stopper plate 28 has a hole 29 in the center. The hole 29 has an elliptical shape in the illustrated example, but may be formed in an appropriate shape.

[0050] The lower end of the stopper plate 28 is pivotally connected to the lower end of the stopper body 26 , and the plate cam 44 is integrally formed at the lower end. The leaf spring 46 is attached to the rod 34 so as to be able to move up and down simultaneously with the rod 34 .

[0051] When the lever 34 descends, the plate cam 44 comes into contact with the plate spring 46 , and the plate spring 46 presses the stopper plate 28 toward one side. Thus, if image 3 The brake pads 28 are shown closed.

[0052] When the lever 34 rises, the plate cam 44 is released from the ...

Abstract

For the yarn that is prone to falling off, the falling off can be released, so that the braking force can be reliably applied to the yarn. The braking surface of at least one of the brake main body and the brake pad of the brake device includes the top surface of the plurality of protrusions formed on at least one of the brake main body and the brake pad. The convex portion extends in a direction transverse to the running direction of the yarn, and at least one is formed on one of the upstream side and the downstream side of the above-mentioned running direction from the center of the brake main body or the brake plate, and a plurality of them are formed on the other side. .

Description

technical field [0001] The invention relates to a brake device for applying a brake to a yarn drawn from a creel. Background technique [0002] Such as Figure 16 As shown, there is a textile machinery creel 10 (Patent Document 1). This creel 10 includes a plurality of bobbins 12 . The yarn 14 wound on these bobbins 12 is pulled out by the warper 16 , and wound around a warp beam (beam) 20 in a sheet form after passing through a guide roller 18 of the warper 16 . [0003] Patent Document 1 Japanese Patent Publication No. Sho 63-28932 [0004] Such a creel 10, such as Figure 17 As shown, a braking device 22 for applying a braking force to the yarn 14 pulled out from the bobbin 12 to adjust the tension of the yarn 14 is arranged on each yarn 14 . The braking device 22 is mounted on a combination rod 24 disposed on the creel 10 . [0005] As one of such braking devices 22, such as Figure 18 shown. This conventional braking device 22 includes: a brake main body 26 insta...
