<p>A procedure for the rapid punching from a metallic band of a blank which is intended, particularly but not exclusively, for the manufacture of a detail of a furniture hinge, comprising the steps of: feeding a continuous metallic band (10) inside a punching group (17) comprising a matrix (21, 23) and a punch (26, 27), mobile in relation to each other to at least partially interpenetrate, punching, without swarf, of at least two blanks (11, 12) to be realised by said metallic band (10). The procedure is characterised in that said punching steps of said at least two blanks are carried out in a single station through a rapid succession of different punching steps on many horizontal planes along fixed and mobile outlines of matrices, supported by elastic elements which gradually give way. <IMAGE> <IMAGE></p> |
