ている。 In this belt molding m, glass launch channel c, etc., in order to reduce the sliding resistance with the window glass, as shown in Figs. The surface is flocked. In addition, in belt molding for hard-top vehicles, as shown in Figures 10 to 13, in addition to the lip part r1 extruded at the same time as the molding body m, there is also a lip part attached by insert injection molding. Short fibers n are also flocked as necessary on the surface of r2 that comes into sliding contact with the window glass G.

好ましくない。 However, with this weather strip, the dust adhering to the window glass gets entangled with the short fibers and becomes caked with long-term use.
There is a risk that the window glass may be worn out due to repeated up and down movement of the window glass. Furthermore, if the short fibers n are not accurately flocked to the tapered tip of the lip r as shown in FIG. 14, as the window glass G slides as shown in FIG. I get caught up in it. Therefore, the short fibers n must be implanted to a position visible from the outside, but the edges of this implanted area tend to meander, which is not very desirable from an aesthetic point of view. Furthermore, in the process of flocking the short fibers n, a liquid adhesive is applied to a predetermined surface along the longitudinal direction of the weather strip using a roll coater or the like, and then the short fibers n are electrostatically flocked and then baked and dried. This requires a long process and also causes the short fibers to scatter, which is unfavorable in terms of the working environment.

The lip part 10b that becomes the contact part is the molding main body 10.
It is integrally molded into. On the surface of the lip portion 10b, a slippery film 11 made of fluorocarbon or an organic silicon compound and having a small coefficient of friction is formed. At least the sliding surface of this slippery coating 11 with the window glass is formed into a surface 11a exhibiting small undulations or irregularities as shown in FIG.

In addition to removing foreign matter by sandwiching the tape from the top and bottom with "Scotchibright" manufactured by 3M, Inc., USA, various treatments are performed to roughen the surface other than the area to which the protective tape 10c is attached. Next, a heat-activated liquid adhesive is applied to the part where the soft polyvinyl chloride will be extruded in the next step using a roll coater 21, and a heating device such as high frequency heating
After the baking treatment in step 2, the strip material 10a
is bent into a predetermined cross-sectional shape using a roll forming machine 23. After that, the adhesive that was partially peeled off during the roll forming process is repaired by the applicator 24, and then the adhesive is repaired by the heating machine 25.
After activating the adhesive, the adhesive is inserted into the mold of an extrusion molding machine 26, and soft polyvinyl chloride is extruded onto a desired portion including the lip portion 10b. Furthermore, after cooling the resin molded part in the cooling tank 27, the cutting machine 28
By cutting it to a predetermined length, you can obtain a molding material.

Further, a plurality of plasma outlet ports 32 are formed in the vacuum bell gear 30, and vacuum traction pumps 33 and 34 are connected to the other end. In the vacuum processing equipment, the vacuum pumps 33 and 34 are operated to
The mold body 10 is vacuumed to about 0 -1 TORR, and foreign matter adhering to the surface of the mold body 10 is removed. Next, while supplying a small amount of rare gas such as helium, neon, argon, etc. or inert nitrogen gas from one gas cylinder 35 , gasified fluorocarbon is supplied little by little from the other gas cylinder 36 . It is irradiated by turning it into plasma and guiding it to the air outlet 32 through the transmission pipe 38.

ーストリツプの製造方法。[Scope of Claims] 1. A weather strip main body formed from soft polyvinyl chloride containing a plasticizer and having a glass contact portion that contacts a vehicle window glass, at least on the surface of the glass contact portion, A method for manufacturing a weather strip, characterized in that a fluorocarbon or an organosilicon compound is irradiated with plasma under vacuum to form a slippery film with a small coefficient of friction. 2. After forming in advance a large number of unevenness or a plurality of protrusions on the surface of the glass contacting part, a fluorocarbon or an organic silicon compound is irradiated with plasma under vacuum to form a slippery film with a low coefficient of friction. However, a method for manufacturing a weather strip according to claim 1.
