Abstract
In an arrangement for producing expanded material (8), in particular from foil-type webs (2) of metal, with a cutting device (3) for producing coherent strips of webs (5) of foil, and with an expanding device (6, 7) for expanding the web (5), the cutting device (3) comprises laser beam, water jet or electron beam (4)-emitting devices which are arranged substantially adjacent each other, transversely to the moving direction of the web (2), and which are controlled by a controlling device.
Claims4
An arrangement for producing expanded material, in particular from foil webs of metal, comprising:
- a cutting device for producing coherent strips of webs of foil;
- and an expanding device for expanding the web, wherein the cutting device comprises:
- a plurality of laser beam, water jet or electron-beam emitting devices which are arranged substantially adjacent each other transversely to the moving direction of the web;
- and a controlling device for individually controlling:
- the activation of the laser beam, water jet or electron beam emitting devices and the energy emitted by the laser beam, water jet or electron beam emitting devices.
A method of producing expanded material, in particular for foil-type webs of metal, the method comprising:
- cutting coherent strips of webs of foil by means of a cutting device, wherein the cutting is effected by means of a plurality of laser beams, water jets or electron beams whose sources are substantially adjacently arranged transversely to a moving direction of a web, wherein the activation of the laser beams, water jets or electron-beams, and the energy of the laser beams, water jets or electron-beams are individually controlled by a controlling device, in order to process varying materials of arbitrary dimensions in various variants;
- and subsequently subjection the cut webs of foil to a mono or double-axial expansion by means of an expanding device.
