ABSTRACT:
Wrapping material (2) supplied to a packaging machine is caused to advance along a predetermined feed path (3) through a first checking station (27a) where an emitter device (29) charges at least one predetermined portion (30, 34) of the wrapping material (2) electrostatically, and a second checking station (27b) where a sensor (31) detects the presence of the electrostatic charges applied previously to the predetermined portion (30, 34) of the material (2). The sensor (31) is positioned along the feed path (3) downstream of and at a predetermined distance from the emitter device (29).
