JPS5825774B2 - How to start up yarn false twisting equipment - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION There is a yarn false twisting device that shortens the cooling zone by bringing running yarn into contact with water between a heater and a false twisting device for efficient cooling.

When starting up such a device, if the yarn comes into contact with water before twisting, the water will remain attached to the yarn and the water will be scattered around the running part of the yarn, and the rotation of the twisting time series will cause the water to come into contact with water. It scatters around, which is extremely undesirable in terms of machine management.

The present invention solves the above-mentioned drawbacks by bringing the yarn into contact with water after twisting.

In FIG. 1, the yarn Y pulled out from the yarn feeding pobbin 1 passes through the first feed roller 2, the first heater 3, the cooling device 4, the false twisting device 5, the second feed roller 6, the second heater 7, and the third feed roller 8 before winding. In the figure, the false twisting device 5 is located at the nip point of the yarn (S; two bells 5a and Sb running in opposite directions) to nip the yarn and false twist it. Although a belt-type false-twisting device is used, it goes without saying that the gist of the present invention is not limited to the above type of false-twisting device.

In FIGS. 2 and 3, the cooling device 4 is surrounded by a box 10 closed on three sides and a cover plate 11 that closes the opening of the box 10, and the thread enters the box 10 through the hole 12 on the bottom of the box, It comes out from the box through the slit 13 on the top surface.

Inside the box 10, the upper part is the water supply pipe 14 and the lower part is the drain pipe 15
A U-shaped water pipe 16 connected to the water pipe 16 is provided.
In the center part is a guide surface 1 with a U-shaped cross section with half cut off.
6a is formed, water flows from top to bottom along the guide surface 16a, thread Y runs from bottom to top, and water is attached to thread Y.

17 is a thread guide fixed to the box 10 by a branch piece 18.

When using yarn, the yarn is guided from the hole 12 to the yarn guide 17 as shown in FIG. 2 Ya, and the yarn is separated from the guide surface 16a, the belts 5a and 5b are separated, and the yarn is passed through the belt intersection.

In this state, the feed rollers 2, 6, 8 and the winding device 9 are started to start the yarn running, and then the belt 5as5b is nipped to start twisting.After this, the yarn is removed from the guide 17 as shown in FIG. The thread is brought into contact with the guide surface 16a as shown in Yb, and water is attached to the thread, and the lid plate 11 is closed.

The above diaphragm is shown in FIG.

In this way, by attaching water to the running yarn after twisting, the attached water is scattered in the form of mist as the yarn rotates, and Box 1
The yarn coming out from strand 3 contains almost no water, so the disadvantage of being scattered around the machine is eliminated.

The sprayed water is collected in the box 10 and flows out to the discharge pipe 15 through the hole 18 on the bottom of the box.

Claims (1)

[Claims] 1. In a yarn false-twisting processing device that is equipped with a cooling device using water between a heater and a false-twisting device that nip yarn between two endless belts that intersect with each other, when starting the false-twisting operation, the yarn is placed in the cooling device. 1. A method for starting a yarn false-twisting apparatus, characterized in that yarn running and twisting are carried out in a state where the yarn is kept away from water, and that the yarn is brought into contact with water after the twisting.
