ABSTRACT:
Machine for manufacturing mesh bags from a continuous roll of tubular mesh, and for filling and closing said mesh bags, which comprise an expansion device which is perimetric to the tubular mesh, the core expander of which is equipped with a vertical aperture which, as if it were a slot, traverses said core expander and connects the two frontal faces thereof and extends from its base to an intermediate point, for which the core expander adopts an inverted “U” shape, the machine also being fitted with preventive welding means, adapted for partially welding the two frontal faces of the tubular mesh and, as the case may be, the adjoining laminates of thermally weldable material through the aperture of the core expander; a traction device which drags a section of the tubular mesh provided with a bottom; conveyor means; and second and third filling and closing stations, respectively, both being arranged linearly.
