METHOD FOR ASSEMBLING TONE HOLE CLOSING MEANS OF WOOD-WIND MUSICAL INSTRUMENTS AND A CONSTRUCTION OF THE MEANS ASSEMBLED THEREBY

摘要

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.
