Abstract
Abstract Apparatus is provided for depositing repeatable patterns of dye-carrying foam onto a moving web. An elongated manifold (26) containing foam under pressure extends transversely to the direction of movement ofthe web. The manifold is provided with a plurality of foam discharge ports which are selectively opened and closedto establish the desired pattern. Variations in the pattern also are produced by reciprocating the manifold transversely to the web's direction of movement while the ports are being opened and closed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
Apparatus for depositing repeatable patterns of dye-carrying foam onto a moving web, comprising: an elongated manifold for holding the foam under pressure, said manifold extending transversely to the direction of movement of said web and having a plurality of foam discharge ports spaced along its length; a plurality of valves within said manifold each associated with a respective port; and means for selectively actuating said valves to open and close said ports to discharge the foam onto the web in a repeatable pattern.
Claim 2
Dependent Claim
83 words
Apparatus for depositing repeatable patterns of dye-carrying foam onto a moving web, comprising: an elongated manifold for holding the foam under pressure, said manifold extending transversely to the direction of movement of said web and having a plurality of foam discharge ports spaced along its length; a plurality of valves within said manifold each associated with a respective port; and means for selectively actuating said valves to open and close said ports to discharge the foam onto the web in a repeatable pattern.
Claim 3
Dependent Claim
28 words
Apparatus as set forth in Claim 1, further comprising: means for reciprocating said manifold transversely to the direction of web movement while selectively opening and closing the ports.
Claim 4
Dependent Claim
62 words
Apparatus as set forth in Claim 1, wherein said valve-actuating means comprises: a plurality of pneumatic cylinders each joined to a respective valve; a source of pressurized air; and a plurality of solenoids each associated with a respective pneumatic cylinder and selectively ac- tuable to direct pressurized air to its associated cylinder to open the valve to which said cylinder is joined.
Claim 5
Dependent Claim
28 words
Apparatus as set forth in Claim 3, further comprising: means for reciprocating said manifold transversely to the direction- of web movement while selectively opening and closing the ports.
Claim 6
Dependent Claim
28 words
Apparatus as set forth in Claim 1, further comprising: an inclined doctor blade positioned adjacent said discharge ports for directing the foam from said ports to the web.
Claim 7
Dependent Claim
25 words
Apparatus as set forth in Claim 5, further comprising: means for adjusting the horizontal and vertical positions of said blade, as well as its inclination.
Claim 8
Dependent Claim
28 words
Apparatus as set forth in Claim 6, further comprising: means for reciprocating said manifold transversely to the direction of web movement while selectively opening and closing the ports.
Claim 9
Dependent Claim
28 words
Apparatus as set forth in Claim 3, further comprising: an inclined doctor blade positioned adjacent said discharge ports for directing the foam from said ports to the web.
