Abstract

The method of manufacturing the pile weather strip for filling the clearances formed at the door or window, is composed of coating thin wall material (11) on the plate-type center material; winding a plurality of piles (12) on the outer side of the wall material; positioning the supporting plates (13),(13') elongated on both the sides of the pile (12) and fusion-welding by HF heating; cutting the strip with the cutting means (14)(14') on the upper/lower sides of the pile (12) and wall material (11).

The present invention relates to a method for producing pile weather strips for blocking gaps formed between doors or windows.

Generally, a gap is formed between a sliding door or a sliding door or window, and the gap is required to prevent rainwater or wind from penetrating from the outside.

Conventionally, the manufacture of pile weather strips provided to block such gaps includes a plurality of piles made of mohair or polypropylene on a woven fabric 1 made of cotton, nylon, or the like as shown in FIG. (2) (2 '), and between the piles (2) and (2'), the wall member (3) is erected and installed to improve the sealing force, and then the back surface of the woven fabric (1) is coated with polyethylene. The support plate 4 is formed.

However, in the prior art as described above, since the woven fabric 1, the pile 2, 2 ', the wall member 3, and the support plate 4 are each made of different materials, the adhesive strength becomes weak, and thus the sealing property This is not only due to the degradation of the water or wind from the outside is not fully functional, but the manufacturing process is complicated, there is a problem that the productivity is lowered and the manufacturing cost is increased.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to improve the strength and durability, the structure is simple, the process is simple and the manufacturing method of the pile weather strip that can reduce the manufacturing cost To provide.

The manufacturing method of the pile weather strip which concerns on this invention made | formed in order to implement | achieve such an objective is a process which coat | covers a thin wall member on the outer side of the plate-shaped center material, and the process of winding a plurality of piles on the outer side of the wall member. And positioning the support plates extending in the longitudinal direction on both sides of the pile and thermally fusion by high frequency heating, and cutting the cutting means on the upper and lower sides of the pile and the wall member, thereby simplifying the manufacturing process and improving productivity. It is characterized by being further improved.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 2 to 4.

FIG. 2 is a view showing a process for manufacturing a pile weather strip according to the present invention. First, the wall member 11 is coated on the outer side of the thin core member 10 as shown in FIG.

At this time, the central material 10 is preferably formed of a steel material, the wall member 11 is a known organic or inorganic thermoplastic or thermosetting material such as vinyl, nylon, polypropylene, polyethylene or other known materials Can be composed of relatively thin and elastic thin plates.

Then, as shown in the drawing (b), a large number of piles 12 are wound on the outer side of the wall member 11.

At this time, the pile 12 may be formed of a synthetic resin such as polypropylene, nylon, and the like, may also be formed of natural fibers such as mohair, wool, or synthetic fibers thereof, the pile 12 is coated with silicon or Ultraviolet rays are irradiated to prevent the absorption of moisture.

Subsequently, supporting plates 13 and 13 'extending in the longitudinal direction with a predetermined width are attached to both sides of the pile 12 wound on the outer side of the center member 10, as shown in the drawing (c). do.

At this time, the support plates 13 and 13 'are fused to each other by heating the wall member 11, the pile 12 and the support plates 13 and 13' at a time by high frequency heating.

Then, when fusion is performed by high frequency heating, as shown in the drawing (d), the center portion of the wall member 11 and the pile 12 is cut by the cutting means 14 and 14 'located at the upper and lower sides. The pile weather strip which is cut | disconnected and has the same left-right formation is completed as shown in FIG.

At this time, the wall member 11, the pile 12 and the support plate 13, 13 'is preferably formed of the same material in order to improve the adhesion.

The core material 10 is again applied to the first process and repeatedly applied to the process as described above.

The pile weather strip manufactured according to the present invention can attach the support plates 13 and 13 'directly to a door or a window, and as shown in FIG. 4, the groove 15a is provided in the plate member 15. And the plate member 15 into which the support plates 13 and 13 'are inserted into the groove 15a may be provided in a door or the like.

As described above, according to the present invention, since the wall member, the pile, and the support plate are thermally fused at a time by high frequency heating, the manufacturing process is simple, and two pile weather strips can be obtained at one time according to the operation of the cutting means. At the same time, the manufacturing cost is remarkably reduced, and in particular, the adhesiveness is improved by the wall member, the pile, and the support plate formed of the same material, thereby increasing the strength and durability.
