A spray gluing unit in a machine for wrapping products advancing along a pass line comprises a gluer equipped with a nozzle having an outlet from which adhesive is directed onto a wrapping material enveloping the products, and a cleaning station equipped with a first movable member carrying a scraper blade and a wetting pad to which silicone oil is supplied; the scraper blade and the wetting pad are designed to interact with a flat surface of the gluer and with an end face of the outlet, occupying substantially the same plane, so as to remove any residual adhesive from the gluer and keep the outlet moistened.
