摘要

In a method and unit for feeding, in a product wrapping machine, a continuous band of wrapping material, the surface of which is pre-impregnated with an aromatising substance, the band (9) is unwound from a reel (14) of wrapping material and is fed, along a given path (P), to a cutting station (10) where the band (9) is cut into lengths, each defining a sheet (6) of wrapping material for a relative product (2); along the path (P) there is a device (23) for cleaning the band (9), designed to remove the aromatising substance from a given portion (22a) of the band (9). <IMAGE>
