Abstract
Abstract Continuous, random dyeing apparatus for carpet or the like comprising a plurality of elongate drums mounted for rotation on parallel, spaced axes, each drum having a plurality of cavities extending partially thereinto from the outer surface thereof, wiper means engaging the outer surface on one side of each drum, along a line parallel to the axis thereof, means for rotating the drums in a direction such that the one sides thereof move downwardy, and means for conducting a dyeing liquid to the intersections between each drum and its associated wiper means. The liquid fills the cavities in the drums, on the one sides thereof, as the drums rotate and the liquid in the cavities passes below the wiper means and is dispensed below the drum onto a carpet moving therebelow.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
172 words
Apparatus for dispensing a liquid dye in a continuous and random pattern onto a moving web of carpet or the like comprising: an elongate first drum mounted for rotation on its axis and having a plurality of cavities extending partially thereinto from the outer surface thereof, some of said cavities having different depths, sizes, or shapes that others of said cavities; wiper means engaging said outer surface longitudinally along one side of said first drum; means for rotating said first drum in a direction such that said one side thereof moves downwardly; means for conducting said liquid dye to the intersection between said first drum and said wiper means whereby said liquid dye fills said cavities in said first drum, on said one side thereof, as said first drum rotates, said liquid dye in said cavities passing below said wiper means and being dispensed below said first drum; and means for conducting a continuous web of carpet or the like beneath said first drum for receipt of said liquid dye dispensed thereby.
Claim 2
Dependent Claim
172 words
Apparatus for dispensing a liquid dye in a continuous and random pattern onto a moving web of carpet or the like comprising: an elongate first drum mounted for rotation on its axis and having a plurality of cavities extending partially thereinto from the outer surface thereof, some of said cavities having different depths, sizes, or shapes that others of said cavities; wiper means engaging said outer surface longitudinally along one side of said first drum; means for rotating said first drum in a direction such that said one side thereof moves downwardly; means for conducting said liquid dye to the intersection between said first drum and said wiper means whereby said liquid dye fills said cavities in said first drum, on said one side thereof, as said first drum rotates, said liquid dye in said cavities passing below said wiper means and being dispensed below said first drum; and means for conducting a continuous web of carpet or the like beneath said first drum for receipt of said liquid dye dispensed thereby.
Claim 3
Dependent Claim
23 words
Apparatus according to claim 1, wherein said outer surface of said first drum is made from a relatively hard material and is smooth.
Claim 4
Dependent Claim
33 words
Apparatus according to claim 2, wherein said wiper means comprises: a wiper blade made from a resilient material, one side edge of said wiper blade engaging said outer surface of said first drum.
Claim 5
Dependent Claim
44 words
Apparatus according to claim 3, further comprising: means forming a trough along said one side of said first drum, said liquid dye conducting means conducting said liquid into said trough, said wiper blade forming at least a portion of the bottom of said trough.

Dependent Claim
33 words
Apparatus according to claim 1, wherein said wiper means comprises: a wiper blade made from a resilient material, one side edge of said wiper blade engaging said outer surface of said first drum.
Claim 7
Dependent Claim
44 words
Apparatus according to claim 5, further comprising: means forming a trough along said one side of said first drum, said liquid dye conducting means conducting said liquid into said trough, said wiper blade forming at least a portion of the bottom of said trough.
Claim 8
Dependent Claim
55 words
Apparatus according to claim 1, further comprising: a plurality of said first drums mounted in parallel, spaced relation; a plurality of said wiper means, one for each of said first drums; means for rotating each of said first drums; and means for conducting a liquid dye to one side of each of said first drums.
Claim 9
Dependent Claim
18 words
Apparatus according to claim 7, wherein all of said first drums are rotated by a single drive means.
Claim 10
Dependent Claim
32 words
Apparatus according to claim 7, wherein said conducting means conducts said continuous web of carpet or the like beneath all of said first drums for receipt of said liquid dye dispensed thereby.
Claim 11
Dependent Claim
105 words
Apparatus according to claim 9, further comprising: a pair of elongate second drums mounted for rotation on parallel, horizontally spaced-apart axes, said conducting means conducting said continuous web of carpet or the like between said pair of second drums, said pair of second drums squeezing said web therebetween; and means for conducting a liquid dye onto the intersection between the face side of said web of carpet or the like and the one of said pair of second drums which engages said face side, said one of said pair of second drums having a plurality of cavities extending partially thereinto from the outer surface thereof.
Claim 12
Dependent Claim
31 words
Apparatus according to claim 10, wherein some of said cavities in said one of said pair of second drums have different depths, sizes or shapes than others of said cavities therein.
Claim 13
Dependent Claim
23 words
Apparatus according claim 10, wherein said cavities in said one of said pair of second drums are arranged in a generally irregular pattern.
Claim 14
Dependent Claim
