Abstract
An apparatus to make a metal mesh having longitudinal rods and transverse rods which have a diameter and reciprocal pitch defined on each occasion according to requirements, is provided, having a first operating group and a second operating group disposed in sequence and functionally coordinated, to obtain a reticular semi-worked product that is completed to make the desired metal mesh.
Claims8
An apparatus to make a metal mesh (11), said apparatus comprising:
- a first feed group (17) configured to feed in first directions (D1) at least two first longitudinal rods (13) lying on a first feed plane (P1);
- a second feed group (18) configured to feed in a second direction (D2), transverse to the first directions (D1), a transverse rod (14) lying on a second feed plane (P2) parallel to said first feed plane (P1);
- a first welding unit (19) configured to weld the transverse rod (14) to said first longitudinal rods (13) to obtain a reticular semi-worked product (12);
- a third feed group (36) configured to feed a second longitudinal rod (15) lying on a third feed plane (P3) parallel to said second feed plane (P2) and parallel to said first longitudinal rods (13) of said reticular semi-worked product (12);
- a second welding unit (37) configured to weld the second longitudinal rod to said transverse rods (14);
- and
- a reception and movement unit (35) configured to receive said reticular semi-worked product (12) from said first welding unit (19) and to move it, along a movement axis (M), toward said second welding unit (37), said reception and movement unit (35) defining a support plane for said reticular semi-worked product (12) which is located parallel to said first feed plane (P1) and said second feed plane (P2),
- wherein between said first welding unit (19) and said reception and movement unit (35) a rotation and positioning member (43) is interposed, configured to rotate said reticular semi-worked product (12).

A method to make a metal mesh (11) which comprises:
- feeding in first directions (D1), via a first feed group (17), at least two first longitudinal rods (13) lying on a first feed plane (P1);
- feeding in a second direction (D2) transverse to the first directions (D1), via a second feed group (18), a transverse rod (14) lying on a second feed plane (P2), parallel to said first feed plane (P1);
- welding, via a first welding unit (19), said transverse rod (14) to said first longitudinal rods (13) to obtain a reticular semi-worked product (12);
- feeding, via a third feed group (36), a second longitudinal rod (15) into an intermediate position between said first longitudinal rods (13) and on a third feed plane (P3), parallel to the second feed plane (P2) and parallel to said first longitudinal rods (13) of the reticular semi-worked product (12);
- rotating said reticular semi-worked product (12), via a rotation and positioning member (43) interposed between the first welding unit (19) and a reception and movement unit (35);
- receiving, via the reception and movement unit (35), said reticular semi-worked product (12) and moving said reticular semi-worked product (12) along a movement axis (M) toward a second welding unit (37), said reception and movement unit (35) defining a support plane for said reticular semi-worked product (12) which is located parallel to said first feed plane (P1) and said second feed plane (P2);
- and
- welding, via the second welding unit (37), the second longitudinal rods (15) to said transverse rods (14).
