Ladder mesh welding machine
TNL  

TNL is a ladder mesh welding machine for the production of curved or straight electro-welded ladders from coil and flat, straight or curved spacers, mainly used in precast tunnel segments reinforcing.
Its advanced technology guarantees perfect straight and curved ladders for precast 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 electro-welded element.

In combination with the mesh welding machine, TNL is the right solution for manufacturing tunnel segments.
