Abstract (en)
[origin: WO2013186346A1] Metal wire supply machine especially connected to devices for inserting, defining and welding metal wires into plastic material enclosed between twinned metal nettings, particularly for introducing, defining and welding crosspieces in automatic "sewing" machines for producing sandwich prefabricated panels made of metal nettings and expanded plastic material. Said devices (2) comprise at least one pair of branches (6, 7) arranged adjacent to the trajectory of moving at least one metal wire (3), one of which branches is fixed (6) and the other constituting a lever of first type (7) actuated pneumatically (10). The branches (6, 7) carry at one end, corresponding to the resistance for the lever (7), at least one gear (11, 12), one of which is driven (11). Both gears (11, 12) are coaxially integral to symmetric wheels (13, 14) circumferentially carrying at least one groove (15), adapted to engage said at least one metal wire (3), drawing it from a storage reel and moving it according to a rectilinear trajectory.
