Automatic high speed welding machine for the production of bags with handles (shopping bags) with 3/4 lanes from a large reel that can be divided into various lanes with the aid of cutting/sealing blades, blown and die-cut with scrap removal by means of a suction system to be wound onto plastic or cardboard cores on fully automatic continuous cycle including the insertion of the cores taken from a large capacity hopper which allows an autonomy of up to 40 changes without operator intervention. Automatic unloading of finished reels onto a collection table or conveyor belt.
The machine can also be equipped with a unit with single folding triangles and reversing bars for the production of star seal bags as well as with a bottom sealing bar to be used for the production of handle-less bags, both flat and gusseted.
