Here, the skirt strap 20 formed by twisting a black film in the step of forming the skirt strap may be integrally formed by fusion to the skirt strap component part configured on the upper end of the skirt strap film 10 .

In another method, the skirt strap 20 may be integrally formed on the upper end of the skirt film 10 by rolling up the upper skirt string component 15 and pressing and molding it.

Here, since the purpose of the skirt string 20 is to not easily come off when picked up with a clip, it will be said that only the purpose of the skirt string 20 needs to be satisfied.

A detailed example of the present invention will be described as follows.

First, a plurality of raw material feeders are configured to simultaneously supply raw materials having different colors by configuring at least two or more raw material feeders, and a plurality of raw material supply steps are performed.

Although this multi-material supply step has already been widely practiced, the methods and structures that have been implemented so far are similar, but the devices for realizing the target according to the intended use may vary.

Next, a melting step of separately melting the plurality of raw materials supplied in the plurality of raw materials supplying step by forming an independent melting chamber is performed.

In this way, each raw material melted in the melting step is subjected to an extrusion step of simultaneously extruding a plurality of molten raw materials through an extrusion hole configured to selectively open and close with a plurality of opening and closing bolts.

A cutting step of performing a molding step in which the molten raw material extruded in the extrusion step is integrally fused to form a single cylindrical film having a plurality of colors, and cutting the film molded into a cylindrical film; A film for skirting is obtained through a winding step of separating the cut film and winding it on a roll, respectively.

The above-described process up to now can be said to be a universal implementation step that is already widely used in the agricultural film manufacturing method.

In order to obtain the skirt film 10, which is the object of the present invention, the present invention goes beyond the above-mentioned general implementation step and forms a part of the cylindrical film molded into the skirt film 10 in the forming step to form the skirt string component 15. A forming step of forming a skirt string component in black; The skirt string component 15 molded in black of the cylindrical skirt film 10 molded in the forming step of the skirt string component part is folded to form one corner, and the skirt string component part 15 is divided into two parts, so that the upper skirt string of the skirt film 10 is divided. a dividing step of obtaining two skirt films 10 so that the constituent part 15 forms a black color; The skirt strap 20 made of the same material, black film, is integrally molded on the black upper part of the skirt strap 10 obtained by dividing it into two, and the configuration further includes a skirt strap forming step. Implement a method of manufacturing a skirt film for a house that protects.

What is important here is to make the skirt strap component 15 formed on the upper end of the skirt film 10 molded in black that blocks ultraviolet rays, and to configure the skirt strap 20 with a black film, which is the same material.

The reason for this is that various methods can be selected in bonding the skirt film 10 to the plastic house, but in general, the upper end of the skirt film 10 is pinched and fixed. Without it, the skirt film 10 is easily separated when it flutters in the wind or when the skirt film 10 is pulled during operation, so it is necessary to put the skirt string 20 to make a coupling end.

In order to solve the above problem, when the skirt strap 20 is coupled to the upper end of the skirt film 10, the skirt strap 20 is easily decomposed by ultraviolet rays and causes a problem, so that the skirt strap 20 is protected from ultraviolet rays. That was the biggest task.

Therefore, until now, by using a nylon string comprising the skirt string 20 separately, the operation was difficult and caused an increase in cost.

In the present invention, a skirt string forming step of forming a skirt string 20 by twisting a black film obtained by separately molding in a film forming machine in the skirt string forming step; a skirt strap supply step of supplying the skirt strap 20 obtained in the skirt strap forming step; The separate skirt string 20 obtained in the skirt string forming step is supplied in the skirt string supply step, and the skirt string 20 is divided into two and formed in black on the upper end of the skirt film 10. ) is wrapped around the skirt string 20 so that the skirt string component 15 is fused, and the black skirt string 20 made by twisting the black film is formed on the top of the skirt film 10 while going through the skirt string embedding step. It constitutes a skirt film for a house that protects the string so as to be integrally wrapped in the part 15 .

That is, in a film molded from different raw materials to produce different colors on a single film, a black skirt string component 15 is formed at the top of the transparent skirt film 10 and a film made of the same material is twisted. (20) is to be wrapped so as to obtain a house skirt film that protects the integrally bonded string.

The present invention as described above can be usefully used in installing an agricultural house, and it will be said that the industrial use value is great.
