A forging technique. A mold and metal plate are rotated, and a spatula is used to rub the metal plate and bring it into close contact with the mold. The rotating machine is very similar to a metalworking lathe, and is often a modified version of a regular lathe, known as a spinning lathe. Products are limited to rotating objects. This technique began to be used for producing washbasins around 1907, and since 1933 it has been possible to produce deep containers. The molds are made of metal or wood, and the spatulas are made of brass or steel. [Katori Tadahiko] Source: Heibonsha World Encyclopedia, 2nd Edition Information |
鍛金の技法。型と金属板とを回転させ,へら(篦)を使用して,金属板をしごきながら型に密着させて成形する技法。回転する機械は金工旋盤によく似ており,多く普通旋盤を改良して使用するが,これをスピニングレースという。製品は回転体に限られる。この技法は1907年ころより洗面器の生産に用いられ始め,33年以後深い容器の生産が可能となった。型には金型と木型があり,へらには黄銅,鋼が使用される。【香取 忠彦】
