Английский разговорный словарь (основной) - burster

ˈbə:stə noun (Science and Technology) A machine for separating or bursting continuous stationery (such as computer listing paper) into individual sheets. Etymology: Formed by adding the agent suffix -er to burst; originally, a burster was a charge of gunpowder for bursting a shell. History and Usage: The word has existed in the technical jargon of office machinery since the fifties, but has only become widely known since the advent of computers and listing paper to nearly all offices, with the attendant nuisance of separating printout into pages. Users who work through a heavy load of fan-fold may find that a 'burster'...is a useful accessory. Susan Curran Word Processing for Beginners (1984), p. 45
