1. A machine for producing uniaxial reinforcing steel bar meshes, the machine comprising:
a steel strip conveyor (1) for conveying a plurality of support strips (2), the plurality of support strips (2) being parallel to one another and spaced apart from one another; and
a reinforcing bar conveyor (3), wherein the reinforcing bar conveyor (3) is configured to convey individual reinforcing bars (4) in a crossing manner onto the plurality of support strips (2), forming a crossing point (5) at each position where each of the individual reinforcing bars (4) crosses each one of the plurality support strips (2); and
a plurality of connecting units (6) operatively arranged at each crossing point (5), wherein each of the plurality of connecting units (6) has a binding wire conveyer (7) configured to feed a binding wire (8) through a rotating unit (9), wherein the rotating unit (9) is configured to be movable relative to each of the plurality of support strips (2) and each of the individual reinforcing bars (4), wherein the rotating unit is arranged on a side of a plane defined by each of the plurality of support strips (2) and each of the individual reinforcing bars (4), wherein each of the plurality of connecting units (6) further has a binding wire guide unit (10), wherein the binding wire guide unit (10) is arranged on an opposite side of the plane, and wherein the binding wire guide unit (10) is configured to frictionally feed out and hold the binding wire (8) fed thereinto by the binding wire conveyer (7) in a direction reverse to an infeed direction, wherein the rotating unit (9) is configured to twist two binding wire strands (11) located on the side of the plane together and cut the two binding wire strands (11) to length, wherein the rotating unit (9) and the binding wire guide unit (10) are configured to move towards each other in a closing manner to form a wire loop connecting each of the plurality of support strips (2) and each of the individual reinforcing bars (4) in such a manner that each of the plurality of support strips (2) and each of the individual reinforcing bars (4) are pressed against each other.
