1. A method for producing logs of continuous thin products in an optimized way, providing for tracking product parameters detected in log winding steps, said method comprising the steps of:
cutting a thin product into a plurality of strips;
winding said strips of a plurality of adjacent logs;
detecting, before or after cutting said thin product into said plurality of strips, parameters associated with said thin product;
storing information on said parameters in a database system, outside said logs, for at least one log of said plurality of adjacent logs;
assigning an ID code to said at least one log;
marking said at least one log with said ID code;
associating, in said database system, said information on said parameters to said ID code of said at least one log, so that information on said parameters of said corresponding log are associated, in said database, to a given ID code;
sharing, in subsequent processing steps of said at least one log, said information on said parameters stored in said database system, wherein said information on said parameters of at least one log, stored in said database system, is used in order to optimize at least one subsequent processing of said product wound into said at least one log, said use providing for recognizing said ID code of said at least one log being processed and said processing of said product of said log based on said information on said parameters of said log;
a first step of winding a master roll or primary log, and a subsequent second rewinding step of winding said master roll or primary log into said plurality of secondary logs, during said second rewinding step occurring said step of cutting into strips, said step of producing said master roll or primary log comprising:
continuously winding said thin product into logs on a winding machine in order to produce at least one primary log;
identifying a first series of said parameters associated with said thin product wound to produce said master roll or primary log;
storing, in said database system outside said master roll or primary log, information on said parameters;
assigning a primary ID code to said master roll or primary log;
marking said master roll or primary log with said primary code;
associating, in said database system, information on said parameters to said primary ID code of said master roll or primary log so that, in said database system, to a given primary ID code information are associated on said parameters of said corresponding master roll or primary log, wherein said rewinding provides for:
cutting a common support core into a plurality of secondary support cores on which said product is rewound, of transverse width equal to a transverse width of said secondary logs;
unwinding said thin product;
cutting said thin product in a product feeding direction, wherein a cut position being such as to cut said product into two or more strips of transverse width equal to said transverse width of corresponding secondary support cores arranged adjacent and aligned together;
rewinding said strips on said respective secondary support cores to produce secondary logs of said thin product;
reading said primary ID code of said master roll or primary log;
acquiring said information on said parameters of said thin product in said master log or primary log, to which said primary ID code, read by said database system, is associated;
assigning secondary ID codes to respective secondary logs;
marking said secondary logs by respective secondary ID codes;
changing said information on said first series of parameters of said master log or primary log into information on said second series of parameters of each secondary log;
associating, in said database system, said secondary ID codes to said respective information on said parameters on corresponding secondary logs, such that a second series of parameters is associated with each secondary log.
