TNL  

The automatic plant “TNL” is designed to manufacture electrowelded ladders, curved or straight, starting from wire in coils. 
Its advanced technology guarantees perfect finished products with the lowest tolerances. The machine comes with a shear movable on 3-axes and a programmed feeding system, which allows to have different cross wire pitches within a single electrowelded element and can be equipped with optional units such as cross wire bending and trimming.
