Description
【発明の詳細な説明】 本発明はバット入りレート材を成珍する方法に関する。[Detailed description of the invention] The present invention relates to a method for producing batted plate material.
例えば、自動車のフロアマットあるいは座席シートのカ
バー等に用いるシート材１は第１図に示すように一対の
表皮２ａ、２ｂ間にクッション性あるいは意匠的効果を
あげるだめのパッド材３を封入している。For example, as shown in FIG. 1, a sheet material 1 used for car floor mats or seat covers has a padding material 3 enclosed between a pair of skins 2a and 2b to provide cushioning properties or a design effect. There is.
このシート材１を成形するには従来から第２図に示すよ
うに両表皮２ａ、、２ｂを縫合して袋状部分を形成し、
この袋状部分内に予め成形したパッド材３を挿入し今度
縫合して、このパッド材３を１寸止している。Conventionally, to form this sheet material 1, as shown in FIG. 2, both skins 2a, 2b are sewn together to form a bag-like part.
A preformed padding material 3 is inserted into this bag-shaped portion and then sewn to hold the padding material 3 in place by one inch.
したがって、バット入りシート材を連続して成形するこ
とは困難となり、バット挿入後に再縫合するだめ、バッ
トの端末部分の仕上りが良好でない。Therefore, it is difficult to continuously mold the sheet material containing the batt, and the finish of the end portion of the batt is not good unless the batt is re-stitched after the batt is inserted.
しかもバット材３を挿入する場合、このバット材３はあ
る程度の剛性を有するものでなければならず、このよう
なバット材３を仲人したシート材１は弾性に乏しいとい
う欠点もある。Moreover, when inserting the bat material 3, the bat material 3 must have a certain degree of rigidity, and the sheet material 1 made of such a bat material 3 has a drawback of lacking elasticity.
本発明は上述した欠点を除去するためになされたもので

きる。In the method of the present invention configured as described above, while the inner skin is preheated, vacuum molding is performed along the inner peripheral surface of the recesses of a mold having recesses each having a predetermined shape, and any of the inner skin produced by this vacuum molding is One of the bulges is filled with a prepolymer mixed with a foaming agent, and the bulges of the inner skin are sealed by heat-melting them together, and the prepolymer is foamed in this sealed space. Because of this, the shape of the bulging part is finished centrally by vacuum molding and pre-heat melting processing, and foamed batts are present in the corners, resulting in a beautiful sheet material at the end. Since the prepolymer, bat width, skin, etc. can be selected arbitrarily, the sheet skin material S1 shown in FIG. 5(a) can be used.
Therefore, the vehicle mat S2i shown in FIG. 5(b) can be used in a wide range of applications. Furthermore, if the above-mentioned method is adopted using a so-called endless production method in which a mold is attached to a chain, a sheet of IAk can be produced in just 1Wj.
