Therefore, the manual rebar feeder of the manual method is low in productivity, difficult to align the left and right ends, and has a problem that only a simple shape can be made because the material is supplied at a predetermined interval of the conveyor.

Therefore, the present invention has been made to solve the above problems, by configuring two types of welding wire mesh of various types used in actual construction sites, that is, two sets of longitudinal and transverse muscle supply device having different lengths and thicknesses, It is an object of the present invention to provide a straight type rebar auto feeder for the production of welded wire mesh that can be produced alternately or intermittently supplying a welded wire mesh of various shapes.

In addition, another object of the present invention is to provide a straight deformed rebar automatic feeding device for the production of welded wire mesh that can maintain the accurate reinforcement spacing and improve productivity.

In addition, the present invention ensures the quality stability and reliability of the building by the production of high-quality welded wire mesh through automatic production system, straight deformed rebar for the manufacture of welded wire mesh (Bar Mesh) that can achieve cost reduction through shortening the air and productivity Another purpose is to provide an automatic feeder.
