    摘要： A process using a mold having at least two complementary parts provided with internal surfaces defining a molding cavity, including placing a cover element on the internal surface of each mold part, extending the periphery of the cover elements beyond that of the internal surfaces, pouring a foaming composition undergoing reaction onto the cover element of one of the mold parts, waiting until the foam further expands and overflows slightly from the part of the mold into which it was poured, applying the other mold part to the first one so as to close the molding cavity, pressing the overflow foam into the extended cover elements, waiting until the foam fully cures, removing the padding from the mold and trimming the cover elements along the line joining them.

    摘要翻译： 一种使用具有至少两个互补部分的模具的方法，所述模具具有限定模制腔的内表面，包括将盖元件放置在每个模具部件的内表面上，使覆盖元件的周边延伸超过内表面的外表面， 发泡组合物在其中一个模具部件的覆盖元件上进行反应，等待直到泡沫进一步膨胀并从其注入的模具的部分中稍微溢出，将另一个模具部件施加到第一模具部分，以便关闭 将溢流泡沫压入延伸的覆盖元件中，等待直到泡沫完全固化，从模具中移除填料并沿着连接它们的线修剪盖元件。
