The cutter of the set is fixed to the receiving groove formed on the upper side of the feed roller fixing bracket, the cutter 1 so that the blade is directed to the bottom, and fixed to the receiving groove formed on the lower side of the fixing bracket so that the blade is directed upward. It consists of a cutter 2 to be installed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

5 is a schematic view of the present invention, Figure 6 is a partial cross-sectional view seen from the front view of the present invention, in the stretch yarn manufacturing machine consisting of an extruder, a stretching machine and a winder with two Ti-die,

A pair of tea dies 101 and 102 coupled to the outlet of the heat transfer means having independent screws 103 and 104 and positioned so that the width of the extrudate is up and down, and

An extruder (100, 100 ') consisting of a cooling unit (110) for simultaneously cooling the molten extrudate extruded from each Ti die (101, 102); and

Feed roller 1 (201) for simultaneously conveying the cooling extrudate transferred from the cooling unit 110,

A set of feed rollers 2 (204-1, 204-2) for separating the cooling melts from the respective dies (101, 102) in the feed rollers (201),

A set of cutters 210 and 220 installed up and down on the feed roller 1 201 and the fixing bracket 202 to cut the cooling melt to be transferred to each feed roller 2 (204-1, 204-2),

A primary stretching unit 230 for simultaneously stretching the cooling melts transferred from each of the transfer rollers 2 204-1 and 204-2 from the upper and lower surfaces thereof, and

It comprises a drawing machine 200 having a drawing rollers 241, 242, 243 to determine the elongation rate of the up and down drawing yarn through the primary drawing unit 230, adjust the draw ratio and then transfer to the second drawing unit (250).

The upper and lower stretched yarns passing through the secondary stretching unit 250 are wound in separate states in the winder 300 including bobbins 310 and 320.

The cutters 210 and 220 of the set are fixed to the cutter groove 202-2 formed on the upper side of the feed roller fixing bracket 202 so that the blade 210-1 faces downward, and It consists of a cutter 2 (202-3) is fixed to the cutter groove (202-3) formed on the lower side of the fixing bracket 202 is installed so that the blade 220-1 is directed upward.

An example of the cutters 210 and 220 is a plurality of fixed blocks arranged at regular intervals as shown in FIG. 6 to fix the blades 210-1 and 220-1 with screws 210-4 and 220-4. (210-2) (220-2), and fixing screws (210-3) (220-3) for fixing the cutter (210, 220) to the fixing bracket (202).

The primary drawing unit 230 includes a drawing housing 230-1 and heaters 230-2 and 230-3 installed on upper and lower inner walls of the drawing housing 230-1, respectively.

According to the present invention configured as described above, each of the extruders 100 and 100 'is driven so that the molten plastic due to the driving of the corresponding screws 103 and 104 is discharged through the respective dies 101 and 102, which are cooled in the cooling unit 110 and the rollers. After passing through (R21-R26) (R11-R16), the feed rollers 201 are combined. However, it is separated again by the feed rollers 204-1 and 204-2. In this case, the present invention is divided into unit fiber yarns while passing through the blades 210-1 and 220-1 of the cutters 210 and 220, respectively, when the feed rollers 201 are separated by the feed rollers 204-1 and 204-2. Lose. In this case, the molten sheet cooled during the transfer from the tea dies 101 and 102 to the feed rollers 204-1 and 204-2 should be conveyed so that the upper and lower widths are the same. This is to allow the stretching at 230 and 250 to be performed simultaneously.

Subsequently, the unstretched fibrous yarn passing through the transfer rollers 204-1 and 204-2 is provided with a heater 230-2 installed on the upper and lower inner walls of the stretched housing 230-1 of the primary stretched portion 230 ( Due to the heating by 230-3 (90-110 degrees Celsius) and the acceleration in the stretching rollers 241, 242, 243, the set draw ratio is obtained. In this case, since the present invention installs heaters 230-2 and 230-3 on the inner wall of the upper and lower walls of the existing drawing housing, the drawing can be performed at the same time up and down to allow the drawing to be doubled in the same space. And the stretching roller (241, 242, 243) to extend the upper and lower unstretched yarn together to provide an effect that is possible without the additional installation of the stretching roller while stretching the stretched yarn twice at a time.

Then, the drawer that passed the drawing roller 243 again separates and transports the upper and lower surfaces of the drawing part 250-1 of the drawing part 250 so as to perform the same function as the drawing part, but the heater 250-. 3) other than the additional equipment is not necessary, of course, the heater (250-2) (250-3) of the secondary stretching unit 250 to perform the function of setting the stretching to the surface 50-70 degrees Celsius.

Lastly, the upper and lower stretched yarns passing through the secondary stretching unit 250 are separated and wound on the corresponding bobbins 310 and 320 of the winder 300.

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, in the present invention, the width of the molten plastic is vertically discharged from the T-die receiving the output of each screw to simultaneously cool the same cooling unit, thereby reducing the cooling unit installation area.

Each of the cooled sheet-like cooling plastics is cut with a cutter on the top and bottom while passing through the feed roller, so that double cutting is possible at the same time.

The cut cutting yarn can be heated in the primary drawing unit with heaters installed up and down, and then passed through the same rollers at the same time, allowing the drawing to be carried out while maintaining the same drawing ratio, and utilizing the existing drawing line. Allow to draw twice without stretching.

In addition, since the present invention uses two T-die at the same time, the output amount is doubled, and it is possible to shorten the length of the T-die in order to increase the output quantity in the past. Provides the effect of preventing safety accidents.

In addition, two screws are used so that different colors can be worked simultaneously. Therefore, it provides the effect of outputting the warp and weft at the same time if necessary.

In addition, the present invention by using only one screw for the test for the experiment to set the normal use of the remaining T-die, thereby solving the problem of a lot of initial loss of the existing setting using a long T-die contributes to cost reduction.
