Abstract
Abstract Strands of textile filaments are impregnated and coated with a liquid material by passing each strand through an immersion bath and in contact with a resiliently compressible and absorptive material which wipes off excess impregnant and coating from the strand. The path and tension of the strand is adjustable to vary the depth at which the strand is embedded into the absorptive material. The absorptive material is in the form of an endless surface constantly rotating to continuously present an unsaturated portion to the strand.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
63 words
THE METHOD OF COMBINING A COATING MATERIAL WITH FILAMENTS OF A STRAND COMPRISING: MOVING SAID STRAND THROUGH A PATH AT A PREDETERMINED TENSION; APPLYING COATING MATERIAL TO SAID STRAND; AND PASSING SAID STRAND INTO CONTACTING RELATIONSHIP WITH A MEMBER OF RESILIENTLY COMPRESSIBLE AND ABSORPTIVE MATERIAL SO THAT THE MEMBER IS COMPRESSED BY THE TENSIONED STRAND SUCH THAT THE STRAND PASSES BELOW THE UNCOMPRESSED
Claim 2
Independent Claim
63 words
THE METHOD OF COMBINING A COATING MATERIAL WITH FILAMENTS OF A STRAND COMPRISING: MOVING SAID STRAND THROUGH A PATH AT A PREDETERMINED TENSION; APPLYING COATING MATERIAL TO SAID STRAND; AND PASSING SAID STRAND INTO CONTACTING RELATIONSHIP WITH A MEMBER OF RESILIENTLY COMPRESSIBLE AND ABSORPTIVE MATERIAL SO THAT THE MEMBER IS COMPRESSED BY THE TENSIONED STRAND SUCH THAT THE STRAND PASSES BELOW THE UNCOMPRESSED
Claim 3
Independent Claim
99 words
The method of combining a coating material with filaments of a strand comprising: moving said strand through a path at a predetermined tension; applying coating material to said strand; advancing said coated strand with sufficient tension along a path into contact with a member having an endless surface of resiliently compressible and absorptive material such that said tensioned strand effects compression of said surface in the region of contact so that said surface partially surrounds said strand to remove excess coating material from said strand; and rotating said strand about its longitudinal axis while said strand contacts said member.
Claim 4
Independent Claim
99 words
The method of combining a coating material with filaments of a strand comprising: moving said strand through a path at a predetermined tension; applying coating material to said strand; advancing said coated strand with sufficient tension along a path into contact with a member having an endless surface of resiliently compressible and absorptive material such that said tensioned strand effects compression of said surface in the region of contact so that said surface partially surrounds said strand to remove excess coating material from said strand; and rotating said strand about its longitudinal axis while said strand contacts said member.
Claim 5
Independent Claim
138 words
The method of combining a coating material with filaments of a strand comprising: moving saId strand through a path at a predetermined tension; applying coating material to said strand; advancing said coated strand with sufficient tension along a path into contact with a member having an endless surface of resiliently compressible and absorptive material such that said tensioned strand effects compression of said surface in the region of contact so that said surface partially surrounds said strand to remove excess coating material from said strand; extracting from said member the excess coating material removed from said strand and absorbed by said member to maintain the absorptive property of the material; and applying liquid to said member to prevent said coating material removed from said strand and absorbed by said member from drying before being extracted from said member.
Claim 6
Independent Claim
138 words
The method of combining a coating material with filaments of a strand comprising: moving saId strand through a path at a predetermined tension; applying coating material to said strand; advancing said coated strand with sufficient tension along a path into contact with a member having an endless surface of resiliently compressible and absorptive material such that said tensioned strand effects compression of said surface in the region of contact so that said surface partially surrounds said strand to remove excess coating material from said strand; extracting from said member the excess coating material removed from said strand and absorbed by said member to maintain the absorptive property of the material; and applying liquid to said member to prevent said coating material removed from said strand and absorbed by said member from drying before being extracted from said member.
Claim 7
Independent Claim
189 words
The method of combining a coating material with filaments of a strand comprising: moving said strand through a path at a predetermined tension; applying coating material to said strand; passing said tensioned strand into contacting relationship with a first member having an endless surface and being of a resiliently compressible and absorptive material to cause the contacted part of said first member to be compressed by said tensioned strand and to partially surround said strand whereby part of said coating material of said strand is removed from said strand and absorbed by said first member; and passing said tensioned strand into contacting relationship with a second member having an endless surface and being of a resiliently compressible and absorptive material to cause the contacted part of said second member to be compressed by said tensioned strand and to partially surround said strand whereby part of said coating material of said strand is removed from said strand and absorbed by said second member, said contacted part of said first member is compressed more and partially surrounds said strand to a greater extent than said contracted part of said second member.
Claim 8
Independent Claim
189 words
The method of combining a coating material with filaments of a strand comprising: moving said strand through a path at a predetermined tension; applying coating material to said strand; passing said tensioned strand into contacting relationship with a first member having an endless surface and being of a resiliently compressible and absorptive material to cause the contacted part of said first member to be compressed by said tensioned strand and to partially surround said strand whereby part of said coating material of said strand is removed from said strand and absorbed by said first member; and passing said tensioned strand into contacting relationship with a second member having an endless surface and being of a resiliently compressible and absorptive material to cause the contacted part of said second member to be compressed by said tensioned strand and to partially surround said strand whereby part of said coating material of said strand is removed from said strand and absorbed by said second member, said contacted part of said first member is compressed more and partially surrounds said strand to a greater extent than said contracted part of said second member.
