Abstract
Abstract An apparatus for coating web and object surfaces wherein a formulation including a coating component dispersed in a solvent vehicle is deposited onto the web or object surface which is then subjected to improved solvent release means for facilitating vaporization of the solvent constituent in the formulation and/or polymerization and crosslinking within the coating component while on the web or object surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
The apparatus of claim 1 wherein said casing includes a solvent recovery hood located adjacent said second and third treatment stages, said solvent recovery hood including an inlet through which evaporated solvent is received in a solvent vapor condensing chamber, said chamber being defined by inner and outer walls through which a coolant is circulated, a condensed solvent outlet in said hood communicating said solvent vapor condensing chamber with said supply of coating formulation, and vacuum means communicating with said solvent vapor condensing chamber, whereby said hood is adapted to operate at a pressure below that at which said coating formulation is applied to said article for facilitating solvent recovery in said apparatus.
Claim 2
Dependent Claim
32 words
The apparatus of claim 1 wherein said application means comprises a nozzle and said coating formulation supply includes a pressurized gas source for pressurized spraying of said coating formulation onto said article.
Claim 3
Dependent Claim
279 words
Apparatus for coating an article with a formulation which includes a polymerizable component and a solvent vehicle, said apparatus comprising a casing having an article-receiving inlet and an article-discharging outlet means for transmitting an article to be coated from said inlet through a plurality of treatment stages in said casing to said outlet, a first treatment stage in said apparatus located along the path of said article-transmitting means and downstream of said inlet, said first treatment stage including application means operatively connected to a supply of a coating formulation which includes a polymerizable component dispersed in a solvent vehicle, said application means being positioned in said casing and along the path of said article-transmitting means for depositing said formulation onto said article, a second treatment stage in said apparatus located along the path of said article-transmitting means and downstream of said first treatment stage, said second treatment stage including an electrode and dielectrically covered member adapted to provide a corona discharge therebetween, said electrode and dielectrically covered member being positioned in said apparatus with respect to said article-transmitting means to subject said article with corona discharge after said coating formulation has been deposited on said article to promote polymerization of said polymerizable component in said formulation in situ on said article, and a third treatment stage in said apparatus located along the path of said article-transmitting means and downstream of said second treatment stage, said third treatment stage including a heater means positioned to direct thermal energy onto said article after said article has been subjected to corona discharge in said second treatment stage for promoting release of solvent from the coating formulation which was deposited on said article.
Claim 4
Dependent Claim
130 words
The apparatus of claim 4 wherein auxiliary solvent release means is provided for facilitating release of the solvent component in said formulation after said formulation has been deposited on said article, said auxiliary solvent release means being positioned in said casing along the path of said article-transmitting means between said second and third treatment stages, said auxiliary solvent release means including a transducer means operatively associated with an ultrasonic generator means, said transducer means beiNg positioned to direct ultrasonic waves on said article after said article has been subjected to corona discharge, whereby said auxiliary solvent release means and said heater means cooperate to provide improved solvent release from said article after said formulation has been deposited thereon and after polymerization and crosslinking of said polymerizable component has taken place.
Claim 5
Dependent Claim
32 words
The apparatus of claim 4 wherein said application means comprises a nozzle and said coating formulation supply includes a pressurized gas source for pressurized spraying of said coating formulation onto said article.
