この考案は、合成樹脂モールに関し、特にその端部にお
いて端末加工を施した合成樹脂モールに関する。[Detailed Description of the Invention] This invention relates to a synthetic resin molding, and more particularly to a synthetic resin molding whose ends are subjected to terminal processing.
自動車又は家具、鞄等の外側面又は縁部等には、従来よ
り緩衝性ならびに装飾性を兼ねて合成樹脂製の帯状のモ
ール体が貼着されている。BACKGROUND OF THE INVENTION Conventionally, synthetic resin band-shaped molding bodies have been attached to the outer surfaces or edges of automobiles, furniture, bags, etc. for both cushioning and decorative purposes.
このモール体は、通常塩化ビニル樹脂、ＡＢＳ樹脂、熱
可塑性ゴム等を押出加工して連続的な帯状物を成形し、
用途に応じ所望の長さに切断して使用される。This molded body is usually made by extruding vinyl chloride resin, ABS resin, thermoplastic rubber, etc. to form a continuous strip.
It is used by cutting it to the desired length depending on the purpose.
そして、その切断されたモール体の端部は、ときにはそ
の切断されたままの状態で使用されることもあるが、例
えば自動車の車体側面等に貼着される場合にあっては、
通常その美観上該端部において端末加工を施すことが行
なわれている。The cut end of the molding body is sometimes used in its cut state, but when it is attached to the side of a car body, for example,
Normally, for aesthetic reasons, terminal processing is performed on the ends.
この端末加工の方法としては、現在法のようなものが知
られている。As a method for this terminal processing, there are currently known methods.
すなわち、適宜長さに切断されたモール体の切断線に対
してＶ字状又はＷ字状の溝を形威し、該溝の両側部分を
中央部に移動し接合して端末を加工する方法がその−で
ある。That is, a V-shaped or W-shaped groove is formed on the cutting line of a molding body cut to an appropriate length, and both sides of the groove are moved to the center and joined to form the end. is that -.
この場合、前記カット面の接合は、熱溶着又は予熱後接
着剤によって接着するのが一般的であり、接合をより強
固かつ美麗に仕上げるために該端末の形状に相応する型
を使用して圧力を加えることも行なわれている。In this case, the cut surfaces are generally bonded by heat welding or adhesive after preheating, and in order to make the bond stronger and more beautiful, a mold corresponding to the shape of the end is used to apply pressure. It is also being added.
他の方法としては、モール体端部をなだらかな曲面に処
理するための熱プレス加工である。Another method is hot pressing to give the end of the molding body a gently curved surface.
上述の方法は一般に端末の熱加工と呼ばれている。The above method is generally referred to as terminal thermal processing.
このように端末加工を施されたモール体は、その裏面側
において接着剤又は両面粘着テープ等により被着物に貼
着される。The molded body which has been subjected to terminal processing in this manner is attached to an adherend on the back side thereof with an adhesive or double-sided adhesive tape.
この段階において、例えば自動車の車体等においては、
モール体が車体曲面に沿ってぴたりと貼着できるように
、通常該モール体を４０′Ｃ〜５０′ｃに加熱すること
が行なわれている。At this stage, for example, in the car body, etc.
The molding body is usually heated to 40'C to 50'C so that the molding body can be tightly adhered along the curved surface of the vehicle body.
しかしながら、このように端末加工を施したモール体を
加熱して被着物に貼着した場合には、極めて好ましくな
い事態を生ずることがある。However, when a molded body whose ends have been processed in this manner is heated and adhered to an object, an extremely undesirable situation may occur.
すなわち、一般にモール体は、その上部が盛り上った凸
形状を有し、その端末部はこれに応じて底部が広がった
テーパー状もしくはなだらかな山状に処理されているた
めに、これを加熱した場合、上部と底部の断面積の相違
に伴う肉厚の差から熱の蓄積量が異なり、従って放熱に
よる冷却時間も異なり、収縮差が生じる。In other words, a molded body generally has a convex shape with a raised upper part, and the end part is processed into a tapered shape or a gentle mountain shape with a correspondingly widened bottom. In this case, the amount of heat accumulated is different due to the difference in wall thickness due to the difference in cross-sectional area of the top and bottom parts, and therefore the cooling time due to heat radiation is also different, resulting in a difference in shrinkage.
一方、この種のモ−ル体は、前記したように押出成形に
よって得られたものがほとんどであって、押出成形時に
おけるモール体長尺方向の延伸歪みが内在しており、モ
ール体が加熱されるところの長手方向の延伸歪みを解消
しようとして収縮するのであるが、この場合においても
、モール体の上部と底部の肉厚の差による収縮差が発生
し、肉厚の大なる底部においてより収縮が大きくなる。On the other hand, most of this type of molded body is obtained by extrusion molding as described above, and there is inherent stretching strain in the longitudinal direction of the molded body during extrusion molding, and the molded body is heated. However, even in this case, a difference in shrinkage occurs due to the difference in wall thickness between the top and bottom of the molding body, and the thicker bottom part shrinks more. becomes larger.
このようにモール体端末部周辺においては、加熱された
モール体の放熱冷却につれて、肉厚の大なる底部におい
ては、肉厚の小なる上部よりも収縮率の大きくなり、上
部と底部の顕著な収縮差が表われ、その結果としてモー
ル体表面側の端末部と本体部との境界近傍に反りが生じ
、被着物との貼着面に間隙が生じ、モール体の貼着効果
を著しく減殺することとなるのである。In this way, around the end of the molding body, as the heated molding body dissipates and cools, the shrinkage rate becomes larger at the thicker bottom part than at the thinner upper part, and the shrinkage rate becomes more pronounced at the top and bottom parts. A difference in shrinkage appears, and as a result, warpage occurs near the boundary between the terminal part on the surface side of the molding body and the main body part, and a gap is created at the adhesion surface to the adherend, which significantly reduces the adhesion effect of the molding body. That's what happens.
このような現象は、モール体の粘着時のみに限らず、粘
着後例えば自動車のように直接日光に曝されることによ
るモール体の温度上昇等によっても惹起されることがあ
る。Such a phenomenon may be caused not only when the molding body adheres, but also due to an increase in temperature of the molding body after adhesion due to direct exposure to sunlight, such as in an automobile.
この考案は、このような欠点を解消するために底部が上
部より断面積の大きい形状に形成されてなる端末部を有
するモール体において加熱又は加温された場合における
収縮差の最も大きいモール体表面側の端末部と本体部の
境界近傍に、モール体長尺方向と略直角方向の凹溝を形
成することにより、モール体に生ずる収縮差を吸収せし
め、もって貼着後の反りを防止し、粘着効果を保持する
ことを企図するものである。In order to eliminate such drawbacks, this invention is based on a molding body surface that has the largest shrinkage difference when heated or warmed in a molding body having an end portion in which the bottom part is formed in a shape with a larger cross-sectional area than the upper part. By forming a concave groove in a direction substantially perpendicular to the longitudinal direction of the molding body near the boundary between the side terminal part and the main body part, the difference in shrinkage that occurs in the molding body is absorbed, thereby preventing warping after pasting, and improving adhesiveness. It is intended to maintain its effectiveness.
以下添付の図面に従って、この考案の詳細を説明する。The details of this invention will be explained below with reference to the attached drawings.

FIG. 2A is a bottom view showing the back side of the toy, in which a groove 20 is formed in the vicinity of the boundary between the terminal part lea and the main body part 10b in a direction substantially perpendicular to the longitudinal direction of the molding body.
この凹溝２０は、第２図口に示すように、モール体表面
を損なわない程度にモール体のほぼ全幅に亘って形成さ
れる。As shown in the opening of FIG. 2, this groove 20 is formed over almost the entire width of the molding body to such an extent that the surface of the molding body is not damaged.

モールの場合、凹溝の幅は約１〜２飄、深さは約２〜４
ｍ程度である。The size of the groove 20 can be appropriately selected depending on the shape of the molding body used. For example, in the case of a side molding for an automobile, the width of the groove is about 1 to 2 mm, and the depth is about 1 to 2 mm. Approximately 2-4
It is about m.

As shown in the figure, even when it is heated or heated and attached to a curved surface such as the side surface of an automobile body, there is a difference in wall thickness due to the difference in cross-sectional area between the top and bottom of the molding body 10. The shrinkage difference due to the groove 20 provided near the boundary between the terminal part 10a and the main body part 10b on the molding body surface 10y
This prevents it from becoming absorbed and warping.
第５図は従来のモール体を示すものであるが、この場合

車体面４０との貼着面に間隙３０が発生する。FIG. 5 shows a conventional molding body. In this case, as mentioned above, warpage occurs on the back surface 10Y of the molding body 10 due to the difference in shrinkage rate between the upper and bottom parts of the molding body.
A gap 30 is generated between the adhesive surface and the vehicle body surface 40.

収されるため、従来のように裏面側に反りを生ずること
は全くない。As described above, according to this invention, even when a molding body with terminal processing is heated and attached to an adherend in a heated state, the difference in shrinkage is greatest between the terminal part on the surface side of the molding body and the main body. Since the concave groove is formed in the vicinity of the boundary in the direction substantially perpendicular to the longitudinal direction of the molding body, the difference in shrinkage is absorbed in the concave groove portion, so there is no warping on the back side as in the conventional case.
また、被着物への貼着後、例えば自動車のように直接日
光に曝されることによってモール体の温度が上昇した場
合においても同様に、反りを生ずる懸念はない。Further, even if the temperature of the molding body rises due to direct sunlight exposure, such as in a car, after being attached to an object, there is no fear of warping.
それゆえ、モール体の被着物に対する粘着効果は数段と
向上し、その耐久性も向上する。Therefore, the adhesion effect of the molded body to the adherend is improved by several orders of magnitude, and its durability is also improved.
