Abstract
An apparatus and method for applying glue is provided in which glue and water are selectively provided to a spray nozzle wherein the water supplied to the nozzle is used to remove any residual glue present after a gluing application. In one preferred embodiment, an outer conduit surrounds an inner conduit defining a first channel therebetween. The inner conduit supplies glue and the first channel supplies water. The outer conduit and the inner conduit are slidably engaged with each other. At least one spray nozzle is in communication with an outer conduit orifice. Slide conduit orifice valving provides selective communication of the outer conduit orifice with an inner conduit orifice and the first channel for selectively supplying glue, water, or neither to the spray nozzle.
Claims15
An apparatus for applying glue, said apparatus comprising:
- an outer conduit having at least one outer conduit orifice;
- an inner conduit surrounded by said outer conduit and defining a first channel therebetween whereby glue is supplied to said inner conduit and water is supplied to said first channel, said outer conduit and said inner conduit being slideably engaged with each other, and said inner conduit having at least one inner conduit orifice;
- at least one spray nozzle in communication with said at least one outer conduit orifice;
- and
- a slide conduit orifice valving providing selective communication of said outer conduit orifice with said inner conduit orifice or with said first channel.
An apparatus for applying glue, said apparatus comprising:
- an outer conduit surrounding an inner conduit which said inner conduit is supplied with glue, said outer conduit having at least one outer conduit orifice and said inner conduit having at least one inner conduit orifice;
- an intermediate conduit disposed between said inner conduit and said outer conduit, said intermediate conduit defining a first water channel between said intermediate conduit and said inner conduit and a second water channel between said outer conduit and said intermediate conduit, being secured relative to said inner conduit for movement therewith, having a water orifice in communication with said first channel and said second channel, and a glue orifice in communication with said inner conduit orifice, whereby relative movement of said inner and intermediate conduit relative to said outer conduit is used to selectively align said outer conduit orifice with said glue orifice, with said water orifice or with neither said glue or water orifice;
- a glue circulation system for circulating glue through the inner conduit;
- a water circulation system for supplying water to said first channel and said second channel;
- and
- at least one spray nozzle in communication with a respective said at least one outer conduit orifice.
