ABSTRACT:
In the application of a solvent to a plastic label carried on the surface of a vacuum drum, the solvent for the plastic 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 labeled and to itself to form a complete sleeve label. The gravure roll is supplied from a fountain that is held against the roll under a spring force. The fountain is in the form of a plastic block which has a face that has several undercut channels in one of which the solvent is supplied and with the others acting 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 a vertical mounting plate by a quick release toggle clamp. The support plate and the spring biased fountain are released by the toggle clamp so the fountain can be removed without requiring any tools for easy inspecting and clearing of any labels that may become adhered to the gravure roll with a minimum of time involved. If it is necessary to change the fountain, only a pair of supply and return hoses to the fountain need to be changed and the new fountain easily and quickly replaced. The toggle clamp and the mounting system serve as the quick disconnect fountain mounting arrangement.
