P55 exploits the strength of punch cutting through an exclusive bridge structure with independent and synchronized mobile carriages. This original solution eliminates length limitations of the cutting area and allows a continuous and productive work cycle: no cuts to remove waste material, piece removal by fall and with the possibility to cut sheets with unlimited length or in rolls. P55 is therefore an "automatic" punching machine that eliminates dead time and does not require constant presence of the operator to remove pieces and waste or for frequent loading of the material.
