Abstract

Abstract A method of stringing a broken treadline in a high-speed apparatus processing multiple running threadlines that includes the steps of splicing the broken threadline onto a running threadline while maintaining tension in the broken threadline. The broken threadline is then carried by the running threadline through the machine''s processing system to the windup station where the two are separated and strung up on new bobbins carried by the windup.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 125 words
A method for restringing an unstrung threadline in a highspeed apparatus processing multiple running threadlines moving under tension said method comprising: a. retrieving the unstrung threadline while moving it through a yarn handling device; b. diverting a running threadline through a yarn passage of the jet splicer portion of a splicer-cutter apparatus; c. diverting the retrieved moving unstrung threadline through said yarn passage while maintaining tension in said unstrung threadline; d. interlacing the moving unstrung threadline with the running threadline by directing air under pressUre into said yarn passage in a plane perpendicular to the running threadlines to form a splice while practically simultaneously cutting the unstrung threadline upon its exit from the jet splicer whereby the unstrung threadline is carried by the running threadline.
Claim 2
Independent Claim 125 words
A method for restringing an unstrung threadline in a highspeed apparatus processing multiple running threadlines moving under tension said method comprising: a. retrieving the unstrung threadline while moving it through a yarn handling device; b. diverting a running threadline through a yarn passage of the jet splicer portion of a splicer-cutter apparatus; c. diverting the retrieved moving unstrung threadline through said yarn passage while maintaining tension in said unstrung threadline; d. interlacing the moving unstrung threadline with the running threadline by directing air under pressUre into said yarn passage in a plane perpendicular to the running threadlines to form a splice while practically simultaneously cutting the unstrung threadline upon its exit from the jet splicer whereby the unstrung threadline is carried by the running threadline.
Claim 3
Dependent Claim 19 words
The method of claim 1, wherein the apparatus is processing the threadlines through a helically wrapped multiple threadline system.
Claim 4
Dependent Claim 18 words
The method of claim 1, wherein the apparatus is processing the threadlines through a S-wrapped multiple threadline system.
Claim 5
Dependent Claim 29 words
The method of claim 1, wherein said unstrung threadline is cut upon its exit from the jet splicer forming a splice tail between 1/4 and 2 inches in length.
Claim 6
Dependent Claim 16 words
The method of claim 1, said high-speed being in excess of 3, 000 yards per minute.
Claim 7
Dependent Claim 12 words
The method of claim 1, said unstrung threadline being a broken threadline.
Claim 8
Independent Claim 159 words
A method for restringing an unstrung threadline in a high-speed apparatus processing multiple running threadlines moving in excess of 3,000 yards per minute under tension from a source to a windup, said method comprising: a. retrieving the unstrung threadline by moving it through a yarn handling device; b. diverting a running threadline through a yarn passage of the jet splicer portion of a splicer-cutter apparatus; c. diverting the retrieved moving unstrung threadline through said yarn passage while maintaining tension in said unstrung threadline; d. interlacing the moving unstrung threadline with the running threadline by directing air under pressure into said yarn passage in a plane perpendicular to the running threadlines to form a splice while practically simultaneously cutting the unstrung threadline upon its exit from the jet splicer whereby the unstrung threadline is carried by the running threadline to the windup; and e. separating the spliced threadlines at the windup, for stringing on new bobbins carried by the windup.
Claim 9
Independent Claim 159 words
A method for restringing an unstrung threadline in a high-speed apparatus processing multiple running threadlines moving in excess of 3,000 yards per minute under tension from a source to a windup, said method comprising: a. retrieving the unstrung threadline by moving it through a yarn handling device; b. diverting a running threadline through a yarn passage of the jet splicer portion of a splicer-cutter apparatus; c. diverting the retrieved moving unstrung threadline through said yarn passage while maintaining tension in said unstrung threadline; d. interlacing the moving unstrung threadline with the running threadline by directing air under pressure into said yarn passage in a plane perpendicular to the running threadlines to form a splice while practically simultaneously cutting the unstrung threadline upon its exit from the jet splicer whereby the unstrung threadline is carried by the running threadline to the windup; and e. separating the spliced threadlines at the windup, for stringing on new bobbins carried by the windup.
Claim 10
Dependent Claim 19 words
The method of claim 7, wherein the apparatus is processing the threadlines through a helically wrapped multiple threadline system.
Claim 11
Dependent Claim 18 words
The method of claim 7, wherein the apparatus is processing the threadlines through a S-wrapped multiple threadline system.
Claim 12
Dependent Claim 29 words
The method of claim 7, wherein said unstrung threadline is cut upon its exit from the jet splicer forming a splice tail between 1/4 and 2 inches in length.
Claim 13
Dependent Claim 16 words
The method of claim 7, said high-speed being in excess of 3, 000 yards per minute.
Claim 14
Dependent Claim 12 words
The method of claim 7, said unstrung threadline being a broken threadline.
