Abstract

La fabrication d'un marteau d'impression pour une imprimante rapide s'effectue essentiellement à partir d'une bande de flasques 30 qui consiste en une bande de métal mince qui est poinçonnée de façon à former un ensemble de plaquettes de flasque 31 reliées par des panes 32. L'assemblage du marteau s'effectue avec les flasques solidaires de la bande, et les marteaux terminés ne sont détachés de la bande qu'au stade final de la fabrication.
