翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Postage stamp separation ： ウィキペディア英語版 Postage stamp separation For postage stamps, separation is the means by which individual stamps are made easily detachable from each other. Methods of separation include: # perforation: cutting rows and columns of small holes # rouletting: small horizontal and vertical cuts # diecutting: cut paper to shape using a metal die—used for self-adhesive stamps. == Early years == In the early years, from 1840 until 1850, all stamps were issued imperforate, and had to be cut from the sheet with scissors or knife. This was time-consuming and error-prone (as mangled stamps of the era attest). Once reliable separation equipment became available, nations switched rapidly. Imperforate stamps have been issued occasionally since then, either because separation equipment was temporarily unavailable (in newborn nations for instance), to makers of automatic stamp vending equipment (the United States did this in the 1900s and 1910s), as novelties for stamp collectors (particularly when stamps are issued in souvenir sheets), or as errors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Postage stamp separation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
