    • The invention relates to a method for permanently obturating holes, especially in metal sheets or plastic parts of automobile bodies. The inventive method is characterized by using a punched article which is at least partially provided on one side with an adhesive material and includes an especially textile support whose surface is greater than the surface of the hole to be obturated and which is especially provided with a non-expanded expandable body in the center of the adhesive side. The punched article is fixed on the hole together with the support in such a manner that the hole is completely covered by the punched article and the expandable body comes to rest inside the hole. The punched article and the expandable body are heated to such an extent that the expandable body expands, heat is supplied until the expanded expandable body completely fills and/or covers the hole, and the expanded expandable body cools off and cures.
    • 本发明涉及一种用于永久堵塞孔的方法,特别是在汽车车身的金属板或塑料部件中。 本发明的方法的特征在于使用冲压制品,所述冲压制品至少部分地设置在粘合剂材料的一侧上,并且包括特别是织物支撑件,其表面大于要被密封的孔的表面,并且特别是设置有非 膨胀的可膨胀体在粘合剂侧的中心。 冲孔制品与支撑件一起固定在孔上,使得孔被冲压制品完全覆盖,并且可膨胀体在孔内停留。 冲压制品和可膨胀体被加热到可膨胀体膨胀的程度,供应热量直到膨胀的可膨胀体完全填充和/或覆盖孔,并且膨胀的可膨胀体冷却和固化。
