1. A vacuum system for securing substrates, comprising:
a suction line,
a conveyor belt configured to receive and transport at least one substrate, wherein the conveyor belt comprises a plurality of perforations,
a plurality of valves corresponding to the plurality of perforations fixed to the conveyor belt such that each valve opens and closes a corresponding perforation of the conveyor belt thereby allowing and impeding, respectively, the passage of a fluid flow through the perforation,
wherein the vacuum system is configured to produce fluid suction through the plurality of perforations towards an interior of the suction line, generating a securing force of the at least one substrate to the conveyor belt,
wherein in an area of the conveyor belt where the suction is applied, the valve comprises a mechanism configured to allow closing of the valve when there is no substrate over the corresponding perforation, and
wherein the vacuum system further comprises a valve opening device along at least one area of the suction line, wherein the opening device is configured to force an open position of the valves.
