Abstract: An air-tight sealing of a pad closing a tone hole of a wind instrument is much facilitated by interposing a foamable thermosetting plastic resin preimpregnated sheet between the bottom wall of a cup and the pad, and heating the preimpregnated sheet thus interposed, so that the sheet is foamed and cured while the pad is maintained in a closed condition over the tone hole of the wind instrument, whereby the pad can be assembled in the cup so as to close the tone hole with sufficient airtightness without requiring any repeated adjustments of the relative positions between the pad and the cup.
Abstract translation: 通过在杯的底壁和垫之间插入可发泡的热固性塑料树脂预浸渍片材，并且将由此插入的预浸渍的片材加热，可以很方便地将密封管乐器的色调孔的垫的气密密封件 片材被发泡和固化，同时将垫片保持在管乐器的音孔上的闭合状态，由此可以将垫组装在杯中，以便以足够的气密封闭色调孔，而不需要对相对的 垫和杯之间的位置。
