Abstract
An apparatus for dispensing liquids which harden in the presence of ambient atmospheric conditions includes a housing for receiving one or more liquids and rotating rollers having roller surfaces which define an orifice through which the liquid is dispensed. A doctoring surface continuously cleans the roller surfaces to eliminate clogging of the orifice or the deposition of hardened material on the housing.
Claims20
An apparatus for dispensing liquids comprising:
- a housing;
- a pair of rollers rotatably mounted on said housing, said rollers having opposed roller surfaces each said surfaces having a first surface portion and a second surface portion, said second surface portion having a smaller diameter than said first surface portion, said second surface portions being spaced apart from each other to define a nozzle having a preselected cross-section;
- liquid supply means for providing a liquid flow through said nozzle;
- and
- drive means for rotating said rollers with said roller surfaces moving in a direction opposite said liquid flow.
An apparatus for dispensing a resinous liquid which hardens when in contact with ambient atmospheric conditions, said apparatus comprising:
- a pump for supplying continuously an input liquid;
- a housing for receiving said input liquid;
- roller means mounted rotatably on said housing and including opposed roller surfaces, each roller surface including a first surface portion and a second surface portion, said second surface portion having a diameter smaller than said first surface portion, said second surface portions defining an output nozzle for generating an output liquid flow from said input liquid;
- and
- drive means for rotating said roller means with said roller surfaces moving in a direction opposite said liquid flow.
An apparatus for dispensing a resinous liquid which hardens in contact with ambient atmospheric conditions, said apparatus comprising;
- a housing with a tank;
- a first and a second roller mounted in said housing and having opposed roller surfaces, each roller surface including a first surface portion and a second surface portion, said second surface portion having a diameter smaller than said first surface portion, said second surface portions defining an orifice for a liquid flow from said tank;
- and
- drive means for rotating said rollers.
