Abstract

1366586 Piano hammers NIPPON GAKKI SEIZO KK 4 Aug 1972 [4 Aug 1971] 36467/72 Heading G5J The felt portion of a piano hammer is impregnated with a vinyl monomer which is subsequently polymerized by heat, light or radiation. The monomer may be a liquid or may be in solution, and may be mixed with other ingredients such as a polymerization initiator and a polymerization inhibitor. Specific monomers are listed. A plate 2 fitted with a felt strip 1 is sliced along lines 3 to produce a plurality of hammers. The invention is stated to produce more uniform impregnation than prior art methods, and better resistance to moisture.
