Automatic winding machine of wire of added material comprising: - a support structure suitable to rest on a support surface; - a loading station, contained in said support structure and configured to receive flanged reels one after and consecutively to the other, coming from a loader which is operatively and physically arranged upstream said automatic winding machine and which receives a plurality of said flanged reels in a predetermined storage order; - a tools group fixed inside said support structure and including at least: • a main gripping and translation gripper cooperating with first actuator means configured to actuate said main gripper to at least pick up one by one said flanged reels from said loading station and apply them to a winding body coupled to said support structure; • an insertion gripper cooperating with second actuation means configured to operate said insertion gripper in vertical and horizontal direction and configured to manipulate an initial end of said wire of added material unwound from a coil and direct it towards said flanged reels supported by said winding body at which said wire of added material, due to the rotation of said body winding, is wound stratified around a central drum of each of said flanged reels forming a plurality of coils of said wire of added material; • a cutting gripper operatively arranged downstream said insertion gripper, configured to obtain a final end of said wire of added material of each of said coils and cooperating with third actuation means configured to operate said cutting gripper in vertical (Y') and horizontal direction, wherein said second actuation means and said third actuation means are distinct from each other, characterized in that at least one of said second actuation means and said third actuation means comprises at least one electric linear actuator (12, 13, 14) electrically connected to a central processing and control unit managing its actuation in such a way as to vary, by means of an automatic, progressive and continuous adjustment, the distance among said second actuation means, said third actuation means and said winding body when the format of said flanged reels to be subjected to rewinding of said wire of added material varies. - a support structure suitable to rest on a support surface;
