第１シール部５の摺動面は、摺動抵抗低減の見地から、
通常、植毛又はウレタン塗装等の滑性処理が施されてい
る。The illustrated weather strip W includes an assembly base 1 that is attached to a sash 23 that slides forward and backward in the housing of a sunroof S, and a window plate gripping part that is located on the inner peripheral side of the assembly base 1 and holds a window plate 25. 3, a lip-shaped or hollow-shaped (hollow-shaped in the illustrated example) first seal part 5 that is located on the outer peripheral side of the assembly base 1 and that contacts or slides on the peripheral wall of the sunroof frontage frame 27; A lip-shaped second seal part 7 is located directly below the front part and is formed only on the front part to complement the action of the first seal part 50. In addition,
From the standpoint of reducing sliding resistance, the sliding surface of the first seal portion 5 is
Usually, a slippery treatment such as flocking or urethane coating is applied.
そして、ウェザストリップＷは、サツシ２３と窓板２５
とともに一体化されて窓体を構成するものである。The weather strip W includes the sash 23 and the window plate 25.
It is integrated with the window body to form the window body.

咬み込むおそれがあるからである。This window body receives negative pressure when the vehicle is running at high speed, and the front side F of the window body lifts up as shown in FIG. 10. At this time, a slight gap is generated between the first seal part 5 and the peripheral wall of the opening frame 27, but the second seal part 7 is the one that complements the seal in this case. If the window is provided around the entire circumference, the sliding resistance when sliding the window will be large, and if the window also has a mechanism to tilt up (usually the rear end is tilted up), it will not tilt down. This is because there is a risk that the second seal portion 7 may get caught on the back side B.
なお、９はルーフ側から侵入して縫た雨滴をサンルーフ
開口枠２７に形成された雨樋２７ａにガイドして落下さ
せるためのガイドリップである（第１０図参照）。Reference numeral 9 designates a guide lip for guiding raindrops that enter from the roof side and fall into a rain gutter 27a formed in the sunroof opening frame 27 (see FIG. 10).

(see figure) were extruded separately and then cut, and the two were connected directly by mold connection or adhesive to form a ring shape (see figure 7).

以下、本発明のウェザストリップの製造方法を口側に基
づいて説明をする。なお、前述で説明した部分について
は、同−図符号を付してその説明の全部または一部を省
略する。An assembly base that is attached to a sash that slides forward and backward in the sunroof housing, a window plate grip that is located on the inner circumference of the assembly base and holds the window plate, and a window plate grip that is located on the outer circumference of the assembly base. a lip-shaped or hollow first seal portion that contacts or slides on the sunroof opening frame peripheral wall;
In a method for manufacturing a weatherstrip, the second seal part is located directly below the first seal part and is formed only in the fluorocarbon part to complement the action of the first seal part. The extruded product is extruded with a cross-sectional shape of -, and a cutting notch is inserted into at least the unnecessary range of the lip base in the second seal part during or immediately after extrusion, and the extruded product is cut into a predetermined length and cut into a ring shape. <Embodiment> The method for manufacturing a weather strip of the present invention will be described below based on the mouth side. It should be noted that the parts explained above will be given the same reference numerals and the explanation thereof will be omitted in whole or in part.
第１図は本実施例のウェザストリップの製造方法におい
て、リング状に接続する前の中間省略斜視図である。FIG. 1 is a perspective view with the middle omitted before being connected in a ring shape in the method for manufacturing the weather strip of this embodiment.
ウェザストリップ本体の押出断面形状は、基本的には、
組付け基部１．窓板把持部３．第１シール部５及び第２
シール部７とを具備し、従来と同様である。The extruded cross-sectional shape of the weatherstrip body is basically:
Assembly base 1. Window plate grip part 3. The first seal part 5 and the second seal part 5
It is equipped with a seal portion 7 and is similar to the conventional one.
そして、ウェザストリップ本体の押出時、第２シール部
７の元部に全長にわたり、切除用ノツチＮを形成する。Then, when extruding the weatherstrip main body, a cutting notch N is formed at the base of the second seal part 7 over the entire length.
この切除用ノツチＮの大きさは、シール部７のリップ厚
さａ＝１〜２．０ｍｍであるとき、開口幅ｂ＝ ０２〜
０．７＋ｎｍ 、深さＣ＝０．５〜１゜０ｍｍとする。The size of this cutting notch N is such that when the lip thickness a of the seal portion 7 is 1 to 2.0 mm, the opening width b is 02 to 2.0 mm.
0.7+nm, depth C=0.5~1°0mm.
ノツチの形成は、通常、押出ダイで押出時形成するが、
押出ダイの直前にノツチ形成刃を間欠的に前進、後退可
能に配設しておき、押出直後に少なくとも、不要範囲（
フロント形成部位Ｆを除く範囲）の第２シール部７のリ
ップ元部に切除用ノツチＮを形成するようにしてもよい
。Notches are usually formed during extrusion using an extrusion die, but
Immediately after extrusion, a notch forming blade is arranged so as to be able to move forward and backward intermittently in front of the extrusion die.
A resection notch N may be formed at the lip base of the second seal portion 7 (excluding the front forming portion F).
また、ノツチの形成部位は、口側では、リップ元部の下
側であるが、元部上側であってもよい。Further, the notch is formed on the lower side of the lip base on the mouth side, but may be on the upper side of the lip base.
このようにして、切除用ノツチＮが第２シール部７のリ
ップ元部に全長にわたり又は部分的に形成さねた押出物
は、所定長に裁断後、口側の如くフロント形成部位との
境界位置で斜めに切れ込み１を人ねて、不要部位を切除
する。この切除作業は、切除用ノツチＮの存在により、
手むしって簡単にできる。In this way, the extrusion in which the excision notch N is formed over the entire length or partially at the lip base of the second seal part 7 is cut into a predetermined length, and then the extrusion is cut to a predetermined length, and then the cutout notch N is formed at the lip base part of the second seal part 7 over the entire length or at the boundary with the front forming part, such as the mouth side. Make a diagonal cut 1 at the desired position and cut out the unnecessary part. This resection work is possible due to the presence of the resection notch N.
You can easily do it by hand.
その後、型接続又は接着剤で直接的に接続してリング状
として、ウェザストリップＷとする（第３図参照）。Thereafter, the weatherstrip W is formed into a ring shape by mold connection or direct connection with an adhesive (see FIG. 3).
すると、フロント側Ｆでは第４図に示すように第２シー
ル部７を具備する断面形状となり、バック側Ｂも含めて
フロント側Ｆを除いた部分は、第５図に示すように第２
シール部を具備しない断面形状となる。As a result, the front side F has a cross-sectional shape including the second seal portion 7 as shown in FIG.
The cross-sectional shape does not include a seal portion.
そして、このようにして製造したウェザストリップを実
車に装着した場合、第２シール部７はフロント側Ｆにの
み形成されており、窓体スライド時摺動抵抗が大きくな
ったり、また、チルトダウン時、第２シール部７のバッ
ク側における咬み込みを配慮する必要がない。When the weather strip manufactured in this way is installed on an actual vehicle, the second seal part 7 is formed only on the front side F, and the sliding resistance increases when the window slides, and when the window is tilted down. , there is no need to take into account the biting of the second seal portion 7 on the back side.

徴とする構成により、下記のような効果を奏する。<Effects of the Invention> The method for manufacturing a weather strip of the present invention comprises: an assembly base attached to a sash that slides forward and backward within the housing of a sunroof, and a window located on the inner peripheral side of the assembly base and holding a window plate. a plate gripping portion, a lip-shaped or hollow first seal portion located on the outer peripheral side of the assembly base and abutting on or sliding on the sunroof frontage frame peripheral wall, and a first seal portion located directly below the first seal portion; In a method for manufacturing a weatherstrip having a lip-shaped second seal part formed only on the front part to complement the action of the seal part, the second seal part is extruded in a cross-sectional shape of -. At the same time, cut the extrudate into a predetermined length into a predetermined length by inserting a cutting notch into at least the unnecessary range of the lip base part in the second seal part during or immediately after extrusion, and cut the extrudate into a predetermined length, and cut the extrudate into a predetermined length before or after connecting it into a ring shape. The structure characterized in that the seal portion is manufactured by cutting out an unnecessary area has the following effects.
本発明の製造方法は、従来の如く、異なった断面形状に
押出す必要がなく、接続箇所も三箇所でなく一箇所で済
み、しかも、上記切除作業は、不要範囲の両端部に切れ
込みを切れて、手むしりで簡便にできる。The manufacturing method of the present invention does not require extrusion into different cross-sectional shapes as in the past, and requires only one connection point instead of three, and the above-mentioned cutting operation involves cutting notches at both ends of the unnecessary area. It can be easily done by hand.
従って、ウェザストリップの製造工数の大幅な削減につ
ながる。Therefore, the number of man-hours required for manufacturing weather strips can be significantly reduced.
