Method of inspection of a wrapping material (2, 3) in a wrapping machine of the tobacco industry, wherein the wrapping material (2, 3) comprises a wrapping component on which at least one additional material is applied; the method of inspection comprising: - an initial configuration step, comprising a step of: - implementing a hyperspectral analysis of the wrapping component and/or of the additional material during at least two subsequent moments of time for obtaining a set of reference spectra corresponding to changes over time of characteristics of the wrapping component and/ or of the additional material; - storing in succession the plurality of reference spectra of the wrapping component and/or of the additional material at set intervals of time during a step of drying of the additional material - a working operational step, comprising the steps of: - advancing the wrapping material (2, 3) along a predetermined advancing path; - implementing a hyperspectral analysis of the wrapping material (2, 3) during said advancing for obtaining a hyperspectral image of the wrapping material (2, 3); - processing the acquired hyperspectral image by means of the reference spectra for identifying the changes of characteristics of the wrapping component and/or of the additional material; - reconstructing a hyperspectral map indicating the identified changes of characteristics of the wrapping component and/or of the additional material; - analysing the reconstructed hyperspectral map in order to assign a quality index to the wrapping material. - an initial configuration step, comprising a step of: - implementing a hyperspectral analysis of the wrapping component and/or of the additional material during at least two subsequent moments of time for obtaining a set of reference spectra corresponding to changes over time of characteristics of the wrapping component and/ or of the additional material; - storing in succession the plurality of reference spectra of the wrapping component and/or of the additional material at set intervals of time during a step of drying of the additional material - implementing a hyperspectral analysis of the wrapping component and/or of the additional material during at least two subsequent moments of time for obtaining a set of reference spectra corresponding to changes over time of characteristics of the wrapping component and/ or of the additional material; - storing in succession the plurality of reference spectra of the wrapping component and/or of the additional material at set intervals of time during a step of drying of the additional material - a working operational step, comprising the steps of: - advancing the wrapping material (2, 3) along a predetermined advancing path; - implementing a hyperspectral analysis of the wrapping material (2, 3) during said advancing for obtaining a hyperspectral image of the wrapping material (2, 3); - processing the acquired hyperspectral image by means of the reference spectra for identifying the changes of characteristics of the wrapping component and/or of the additional material; - reconstructing a hyperspectral map indicating the identified changes of characteristics of the wrapping component and/or of the additional material; - analysing the reconstructed hyperspectral map in order to assign a quality index to the wrapping material. - advancing the wrapping material (2, 3) along a predetermined advancing path; - implementing a hyperspectral analysis of the wrapping material (2, 3) during said advancing for obtaining a hyperspectral image of the wrapping material (2, 3); - processing the acquired hyperspectral image by means of the reference spectra for identifying the changes of characteristics of the wrapping component and/or of the additional material; - reconstructing a hyperspectral map indicating the identified changes of characteristics of the wrapping component and/or of the additional material; - analysing the reconstructed hyperspectral map in order to assign a quality index to the wrapping material.
