Abstract
Abstract A drive belt for use on a yarn spinning frame or the like, and which is adapted to run substantially lint free. The belt comprises interwoven cotton and nylon yarns, with at least several of the yarns including an electrically conductive component in either continuous or staple filament form blended therewith to facilitate discharge of static electricity. Also, a cured resin substantially fills the interstices of the woven material to prevent lint or yarn fly from lodging therein.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
60 words
A strong, substantially non-stretching drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven cotton and nylon yarns, at least several of said yarns including an electrically conducive component blended therewith, and a cured resin substantially filling the interstices of the tape.
Claim 2
Dependent Claim
60 words
A strong, substantially non-stretching drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven cotton and nylon yarns, at least several of said yarns including an electrically conducive component blended therewith, and a cured resin substantially filling the interstices of the tape.
Claim 3
Dependent Claim
15 words
The drive belt as defined in claim 1 wherein said nylon yarns are heat stabilized.
Claim 4
Dependent Claim
61 words
The drive belt as defined in claim 1 wherein said several yarns including a conductive component are of a linear density substantially greater than the linear density of the remaining cotton and nylon yarns whereby portions of the conductive component extend above the surface of the tape to facilitate contact with a spindle whorl or the like for discharging static electricity.
Claim 5
Dependent Claim
19 words
The drive belt as defined in claim 1 wherein said electrically conductive component comprises staple filaments of stainless steel.
Claim 6
Dependent Claim
13 words
The drive belt as defined in claim 1 wherein said resin comprises polyurethane.
Claim 7
Dependent Claim
130 words
A strong, substantially non-stretching drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape comprising interwoven filling and warp yarns, said filling yarns comprising cotton, and said warp yarns comprising nylon yarns and cotton yarns, said cotton warp yarns including an electrically conductive component blended therein and having a linear density substantially greater than the linear density of said cotton filling yarns and nylon warp yarns whereby portions of said conductive component extend above the surface of the tape to facilitate discharge of static electricIty onto an adjacent surface, and a cured resin substantially filling the interstices of the tape to thereby prevent yarn fly from collecting on the tape by entering the interstices.
Claim 8
Dependent Claim
130 words
A strong, substantially non-stretching drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape comprising interwoven filling and warp yarns, said filling yarns comprising cotton, and said warp yarns comprising nylon yarns and cotton yarns, said cotton warp yarns including an electrically conductive component blended therein and having a linear density substantially greater than the linear density of said cotton filling yarns and nylon warp yarns whereby portions of said conductive component extend above the surface of the tape to facilitate discharge of static electricIty onto an adjacent surface, and a cured resin substantially filling the interstices of the tape to thereby prevent yarn fly from collecting on the tape by entering the interstices.
Claim 9
Dependent Claim
30 words
The drive belt as defined in claim 6 wherein said conductive component is stainless steel and comprises at least about 1 percent of the weight of said cotton warp yarns.
Claim 10
Dependent Claim
13 words
The drive belt as defined in claim 6 wherein said resin is polyurethane.
Claim 11
Dependent Claim
32 words
The drive belt as defined in claim 6 wherein said cotton filling yarns and said cotton warp yarns comprise long staple cotton filaments and said nylon warp yarns comprise spun nylon filaments.
Claim 12
Dependent Claim
95 words
The process for fabricating a strong substantially non-stretching drive belt adapted to run substantially lint free on yarn spinning and processing machinery, comprising the steps of impregnating a woven tape comprising cotton, nylon and electrically conductive components in a resin bath, tensioning the impregnated tape to approach its breaking point, calendaring the impregnated tape while maintain-ing the same under tension to cause the resin to thoroughly penetrate and fill the interstices of the tape, and heating the tape while maintaining the same under tension to heat stabilize the nylon filaments and to cure the resin.
Claim 13
Dependent Claim
95 words
The process for fabricating a strong substantially non-stretching drive belt adapted to run substantially lint free on yarn spinning and processing machinery, comprising the steps of impregnating a woven tape comprising cotton, nylon and electrically conductive components in a resin bath, tensioning the impregnated tape to approach its breaking point, calendaring the impregnated tape while maintain-ing the same under tension to cause the resin to thoroughly penetrate and fill the interstices of the tape, and heating the tape while maintaining the same under tension to heat stabilize the nylon filaments and to cure the resin.
Claim 14
Dependent Claim
21 words
The process as defined in claim 10 wherein the step of heating the tape includes subjecting the same to infrared radiation.
Claim 15
Dependent Claim
85 words
A drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven yarns, at least several of said yarns having a linear density substantially greater than the linear density of the remaining yarns and including an electrically conductive component blended therewith, whereby portions of the conductive component extend above the surface of the tape to facilitate contact with a spindle whorl or the like for discharging static electricity.
Claim 16
Dependent Claim
85 words
A drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven yarns, at least several of said yarns having a linear density substantially greater than the linear density of the remaining yarns and including an electrically conductive component blended therewith, whereby portions of the conductive component extend above the surface of the tape to facilitate contact with a spindle whorl or the like for discharging static electricity.
Claim 17
Dependent Claim
34 words
The drive belt as defined in claim 12 wherein said tape further comprises a cured resin substantially filling the interstices of the tape to thereby prevent lint or the like from becoming lodged therein.
Claim 18
Dependent Claim
94 words
A drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven cotton and polymeric yarns, at least several of said cotton yarns having a linear density substantially greater than the linear density of the remaining cotton and polymeric yarns and including staple filaments of stainless steel blended therewith, whereby portions of the stainless steel filaments extend above the surface of the tape to facilitate contact with a spindle whorl or the like for discharging static electricity.
Claim 19
Dependent Claim
94 words
A drive belt characterized as being adapted to run substantially lint free on the whorl of a yarn spinning frame or the like and comprising a tape including interwoven cotton and polymeric yarns, at least several of said cotton yarns having a linear density substantially greater than the linear density of the remaining cotton and polymeric yarns and including staple filaments of stainless steel blended therewith, whereby portions of the stainless steel filaments extend above the surface of the tape to facilitate contact with a spindle whorl or the like for discharging static electricity.
