Abstract
Abstract A method of producing a fabric containing organic yarns and glass yarns so woven that the composite reinforcement is extensible, due to the inherent stretchability of the organic yarns and due to the particular configuration in placement and orientation of the glass component, until the glass component is in line with the direction of tensile force, whereupon the glass yarns assume the load; the organic yarns having, in the meantime, become stretched to some point short of the elastic limit or to its ultimate elastic limit.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
178 words
The method of making a reinforcement member for rubber and rubber-like goods, said method comprising: forming strands of gathered-together filaments of glass, combining a plurality of said strands to form a first yarn, forming a woven fabric including, in one direction, a plurality of said first yarns and, in parallel relationship, second yarns of a material having an extensibility greater than said glass, said fabric defining a pattern in which both first and second yarns sinuously engage with the other components of the fabric and in which the yarns of glass filaments are longer and exhibit a sinuosity which is greater than the sinuosity of said second yarns, which are accordingly shorter per unit length of fabric than said first yarns, whereby a tensile load imposed on said fabric in the said direction will be borne first by said second yarns, causing a simultaneous elongation of said second yarns and a straightening out of the originally more sinuous glass yarns until said glass yarns assume a part of said tensile load, and collecting the resulting woven sheet good.
Claim 2
Independent Claim
178 words
The method of making a reinforcement member for rubber and rubber-like goods, said method comprising: forming strands of gathered-together filaments of glass, combining a plurality of said strands to form a first yarn, forming a woven fabric including, in one direction, a plurality of said first yarns and, in parallel relationship, second yarns of a material having an extensibility greater than said glass, said fabric defining a pattern in which both first and second yarns sinuously engage with the other components of the fabric and in which the yarns of glass filaments are longer and exhibit a sinuosity which is greater than the sinuosity of said second yarns, which are accordingly shorter per unit length of fabric than said first yarns, whereby a tensile load imposed on said fabric in the said direction will be borne first by said second yarns, causing a simultaneous elongation of said second yarns and a straightening out of the originally more sinuous glass yarns until said glass yarns assume a part of said tensile load, and collecting the resulting woven sheet good.
Claim 3
Dependent Claim
22 words
The method as claimed in claim 1, which includes the step of calendering elastomeric stock material on said resulting woven sheet good.
Claim 4
Dependent Claim
32 words
The method as claimed in claim 1, one of said combined plurality of strands or said first yarns is impregnated with a vulcanizable elastomeric impregnant prior to forming into a woven fabric.
Claim 5
Dependent Claim
24 words
The method as claimed in claim 1, wherein said resulting woven sheet good is passed through an impregnant bath of a vulcanizable elastomeric impregnant.
Claim 6
Dependent Claim
28 words
The method as claimed in claim 1, wherein said second yarns are formed of an extensible material selected from the group consisting of organic, synthetic and natural materials.
Claim 7
Dependent Claim
17 words
The method as claimed in claim 1, wherein the second yarns include different yarns of different elongation.
Claim 8
Dependent Claim
30 words
The method as claimed in claim 1, wherein said filaments of glass are continuous and said yarns having an extensibility greater than glass are formed of staple strands of glass.
Claim 9
Dependent Claim
24 words
The method as claimed in claim 7, wherein said resulting woven sheet good is passed through an impregnant bath of a vulcanizable elastomeric impregnant.
Claim 10
Dependent Claim
29 words
The method as claimed in claim 7, wherein said yarns of continuous and staple glass are impregnated with a vulcanizable elastomeric impregnant prior to forming into a woven fabric.
Claim 11
Independent Claim
201 words
The method of making a reinforcement member for rubber and rubber-like goods, said method comprising: forming strands of gathered-together filaments of glass, treating said strands of glass filaments with an anchoring agent, weaving a fabric which includes in either the warp or fill direction said treated strands and, in parallel relationship therewith, yarns of a material having an extensibility greater than said glass, said weaving resulting in a woven fabric having a pattern in which the aforementioned strands and yarns sinuously engage with the other components of The fabric and in which the strands of glass filaments exhibit a sinuosity which is greater than the sinuosity of the yarns formed of other material, said strands of glass having a greater length per unit length of fabric than the yarns of more extensible material by reason of said sinuosity, whereby a tensile load imposed on said fabric axially with respect to said strands and yarns will be borne first by said more extensible yarns, causing a simultaneous elongation of said more extensible yarns and a straightening out of the originally more sinuous glass strands until said glass strands assume a part of said tensile load, and collecting the resulting woven sheet good.
Claim 12
Independent Claim
201 words
The method of making a reinforcement member for rubber and rubber-like goods, said method comprising: forming strands of gathered-together filaments of glass, treating said strands of glass filaments with an anchoring agent, weaving a fabric which includes in either the warp or fill direction said treated strands and, in parallel relationship therewith, yarns of a material having an extensibility greater than said glass, said weaving resulting in a woven fabric having a pattern in which the aforementioned strands and yarns sinuously engage with the other components of The fabric and in which the strands of glass filaments exhibit a sinuosity which is greater than the sinuosity of the yarns formed of other material, said strands of glass having a greater length per unit length of fabric than the yarns of more extensible material by reason of said sinuosity, whereby a tensile load imposed on said fabric axially with respect to said strands and yarns will be borne first by said more extensible yarns, causing a simultaneous elongation of said more extensible yarns and a straightening out of the originally more sinuous glass strands until said glass strands assume a part of said tensile load, and collecting the resulting woven sheet good.
Claim 13
Dependent Claim
24 words
The method as claimed in claim 10, wherein said formed woven fabric is passed through an impregnant bath inclusive of a vulcanizable elastomeric impregnant.
Claim 14
Dependent Claim
35 words
The method as claimed in claim 10, wherein said anchoring agent is selected from the group consisting of amino silanes, Werner type compounds complexed to contain an amino, carboxyl or other active hydrogen-containing organic group.
Claim 15
Dependent Claim
27 words
The method as claimed in claim 10, wherein said strands of glass filaments are impregnated with a vulcanizable elastomeric impregnant prior to forming into a woven fabric.
Claim 16
Dependent Claim
17 words
The method as claimed in claim 10, wherein the second yarns include different yarns of different elongation.
Claim 17
Dependent Claim
28 words
The method as claimed in claim 14, wherein said second yarns are formed of an extensible material selected from the group consisting of organic, synthetic and natural materials.
