Abstract

Dispositif pour découper des bandes de feuille métallique incurvées par oxycoupage. Les moyens de reproduction de profil de découpage consistent en une came montée sur un portique se déplaçant horizontalement et entraînée en rotation avec un rapport de transmission pré-établi par rapport à la vitesse de déplacement du portique; un dispositif avec taquet, associé à cette came, suit le profil de la came et en transmet les variations au chalumeau mobile sur le portique perpendiculairement au sens de déplacement de celui-ci. Applicable notamment aux profilés soudés.Device for cutting strips of curved metal foil by flame cutting. The cutting profile reproducing means consists of a cam mounted on a gantry moving horizontally and driven in rotation with a transmission ratio pre-established with respect to the speed of movement of the gantry; a device with a cleat, associated with this cam, follows the profile of the cam and transmits its variations to the mobile torch on the gantry perpendicular to the direction of movement of the latter. Applicable in particular to welded sections.
