Abstract

A method (700) for assessing quality of a longitudinal sealing (402, 502) in a roll fed packaging machine. The roll fed packaging machine comprises a packaging material receiver arranged to receive a web (104) of packaging material (202), wherein the packaging material (202) comprises an outer protective layer (204), an inner protective layer (206) and an intermediate strengthening layer (208), and wherein the web (104) has a first (302) and second (304) longitudinal side section, a strip receiver arranged to receive a protective strip (106), wherein the protective strip (106) has a first (306) and a second (308) longitudinal side section, a strip applicator (122) arranged to form a longitudinal strip sealing (502) by applying the protective strip (106) on the web (104) by heating the web (104) and the protective strip (106) and pressing the web (104) and protective strip (106) together and a strip application camera (108) arranged to capture strip application image data from a strip application area (310). The method comprises receiving (710) strip application image data of the strip application area (310), extracting (712) features from the strip application image data, wherein the features are related to effects of the heating provided by the strip applicator (122), determining (714) a strip application status by evaluating the features, wherein the strip application status relates to the quality of the longitudinal strip sealing (502), and transmitting (716) the strip application status, thereby providing a quality assessment of the longitudinal strip sealing (502).
