Abstract
Abstract A method and apparatus for randomly applying a foam composition containing a coloring agent dispersed therein onto a textile fabric is disclosed. The coloring agent is mixed into the foam in a non-homogeneous manner and randomly applied onto a fabric in a system having random application means for delivering the foam-coloring agent composition to a depositing means which is rotated and moved transverse to the direction of travel of the fabric being treated. The foam-coloring agent composition is caused to flow axially and in one embodiment over the edges of a baffle means in a random manner onto the textile fabric being treated so as to impart a random application of the coloring agent thereon.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
188 words
An apparatus for applying a foamed composition onto a substantially horizontal textile fabric to impart a generally random coloring effect to the fabric which comprises: means for supplying a foam composition including a coloring agent therein; conduit means through which said foam composition and coloring agent are routed, said conduit means having the exit portion thereof disposed in a generally downwardly directed vertical direction; directing means disposed above and spaced from the substantially horizontal fabric being treated, said directing means being provided in association with the exit portion of said conduit means for causing the flow of the foam-color containing composition to be directed at least partially in a substantially horizontal direction prior to being fed downwardly from said directing means onto the fabric being treated; means for moving said conduit and directing means transverse to the direction of travel of said fabric being treated; and means for moving said directing means relative with respect to at least a portion of said conduit means independently of the foam supply means so as to cause the foam-color containing composition to impart a generally random coloring effect to the fabric.
Claim 2
Independent Claim
188 words
An apparatus for applying a foamed composition onto a substantially horizontal textile fabric to impart a generally random coloring effect to the fabric which comprises: means for supplying a foam composition including a coloring agent therein; conduit means through which said foam composition and coloring agent are routed, said conduit means having the exit portion thereof disposed in a generally downwardly directed vertical direction; directing means disposed above and spaced from the substantially horizontal fabric being treated, said directing means being provided in association with the exit portion of said conduit means for causing the flow of the foam-color containing composition to be directed at least partially in a substantially horizontal direction prior to being fed downwardly from said directing means onto the fabric being treated; means for moving said conduit and directing means transverse to the direction of travel of said fabric being treated; and means for moving said directing means relative with respect to at least a portion of said conduit means independently of the foam supply means so as to cause the foam-color containing composition to impart a generally random coloring effect to the fabric.
Claim 3
Dependent Claim
64 words
An apparatus in accordance with claim 1 wherein said directing means comprises a nozzle connected to the exit portion of said conduit means, said nozzle having the lower end thereof closed and including a plurality of spaced apertures disposed along the side thereof so as to cause the flow of the foam-color containing composition to be directed axially therethrough onto the fabric being treated.
Claim 4
Dependent Claim
18 words
An apparatus in accordance with claim 2 wherein said apertures are in the form of spaced slitted members.
Claim 5
Dependent Claim
115 words
An apparatus in accordance with claim 1 which further includes a conduit opening disposed at the exit portion of said conduit means and wherein said directing means comprises a baffle means spaced from said conduit opening and interposed between said opening and the fabric being treated so as to distribute the foam and coloring agent exiting through said opening, said baffle means comprising a plate member of a predetermined configuration disposed with one surface thereof spaced from said conduit opening and being of a size such that the foam composition and coloring agent exiting from said conduit opening flows over the edges of said baffle means onto the surface of the textile fabric being treated.
Claim 6
Dependent Claim
35 words
An apparatus in accordance with claim 4 wherein said baffle means is in the form of a substantially flat plate member having the planar surface thereof generally horizontally disposed and spaced from said conduit opening.
Claim 7
Dependent Claim
35 words
An apparatus in accordance with claim 5 wherein said means for moving said directing means comprises drive means coupled to said baffle means adapted to impart a rotary or oscillating motion to said baffle means.
Claim 8
Dependent Claim
38 words
An apparatus in accordance with claim 6 which further includes coupling means for mounting said baffle means to said conduit means and adjustment means to facilitate adjustment of the spacing of said baffle means from said conduit opening.
Claim 9
Dependent Claim
80 words
An apparatus in accordance with claim 6 which further includes a rotary member disposed adjacent the exit portion of said conduit opening to facilitate relative rotary motion between said conduit opening disposed at the exit portion and the remainder of said conduit and wherein said baffle moving means comprises drive means, and coupling means connecting said drive means and said conduit opening so as to impart a rotary or oscillating movement to said conduit opening and baffle means attached thereto.
Claim 10
Dependent Claim
30 words
An apparatus in accordance with claim 1 wherein said supplying means comprises foam supply means; coloring agent supply means; and means for mixing said coloring agent and said foam composition.
