<p>The invention relates to a machine for the continuous production of mesh bags. The inventive machine comprises: a device (100) for supplying tubular mesh (1, 101) made from a heat-sealable material; two devices for supplying (2, 110, 120) sheets of heat-sealable material (21, 111, 121); an expansion device (4) for the tubular mesh (1, 101) having an expansion core (41) which is disposed vertically to float inside the tubular mesh (1, 101), the latter being formed by two parallel faces, one at the front and one at the rear, and two parallel lateral faces; two longitudinal welding devices (5, 140) for joining the sheet to the respective faces of the tubular mesh (1, 101); an adapter device (6) for adapting the perimeter of the expanded tubular mesh (1, 101); a folding device (7); a traction device (8); and a device for forming bags (9).</p> |
