DISPOSITIVO UMIDIFICATORE A CAMBIORAPIDO PER APPARECCHI APPLICATORI DI ETICHETTE A MANICOTTO IN MATERIALE TERMOPLASTICO SU BOTTIGLIE E SIMILI

In the application of a solvent to a plastics label carried on the surface of a vacuum drum, the solvent for the plastics label is transferred from a gravure roll to the label at finite areas on the label so that the label can adhere to the bottle to be labelled and to itself to form a complete sleeve label. The gravure rollis supplied from a fountain that is held against the roll under a spring force. The fountain is in the form of a plastics block which has a face that has several undercut chinnels, in one of which the solvent is supplied. The others act as doctor channels to carry away any excess solvent from the roll surface. The fountain block is held by a vertical support plate that, in turn, is held to the surface of v vertical mounting plate by a quick release toggle clamp.
