Abstract
Abstract A mophead has generally U-shaped loops extending to both sides of the center band and the loops are extensively twisted along their lengths. In the method of making the mophead, an assembly of loops formed from twisted yarn is suspended from adjacent the centerline thereof and is agitated until extensive twisting of the loops along the length thereof is produced.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
161 words
In a method of making a mophead having elongated loops, the steps comprising: a. forming absorbent twisted yarn into an array of a multiplicity of elongated U-shaped loops extending in both directions from the centerline of said arRay with the arcuate closed end portions thereof providing the end portions of said array, said array being of substantial width and said loops being of substantially equal length from said centerline and being closely spaced together in said array: b. applying securing means to said array adjacent said centerline to secure all of said loops in said array together to form a secure assembly thereof; c. suspending said assembly adjacent said securing means with said loops depending freely therefrom; and d. subjecting said suspended assembly to agitation for a period of time sufficient to produce to agitation twisting of said loops about their longitudinal axes, said loops having a multiplicity of twists spaced along at least the major portion of the length thereof.
Claim 2
Dependent Claim
161 words
In a method of making a mophead having elongated loops, the steps comprising: a. forming absorbent twisted yarn into an array of a multiplicity of elongated U-shaped loops extending in both directions from the centerline of said arRay with the arcuate closed end portions thereof providing the end portions of said array, said array being of substantial width and said loops being of substantially equal length from said centerline and being closely spaced together in said array: b. applying securing means to said array adjacent said centerline to secure all of said loops in said array together to form a secure assembly thereof; c. suspending said assembly adjacent said securing means with said loops depending freely therefrom; and d. subjecting said suspended assembly to agitation for a period of time sufficient to produce to agitation twisting of said loops about their longitudinal axes, said loops having a multiplicity of twists spaced along at least the major portion of the length thereof.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein said depending loops are arranged with their longitudinal axes substantially parallel when said loops are freely depending.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein at least some of said generally U-shaped loops at least partially overlie some other loops.
Claim 5
Dependent Claim
43 words
The method of claim 1 wherein said forming step includes the forming of an elongated yarn element into one of said generally U-shaped loops on each side of said centerline with the free ends thereof being disposed adjacent said centerline of said array.
Claim 6
Dependent Claim
34 words
The method of claim 1 wherein said forming steps include the winding of an elongated yarn element back and forth into a multiplicity of loops on each side of said centerline of said array.
Claim 7
Dependent Claim
17 words
The method of claim 5 wherein all of said loops are from a single of twisted yarn.
Claim 8
Dependent Claim
60 words
The method of claim 1 further includes after said agitating step, the step of fanning out said loops from said securing means into a generally planar form on each side of said centerline having a lateral region intermediate said closed end and said centerline and affixing flexible interconnecting means to said loops in said lateral region to secure them together.
Claim 9
Dependent Claim
26 words
The method of claim 1 further including a final step of securing at least one more additional assembly in superposed relationship to provide a laminated assembly.
Claim 10
Dependent Claim
29 words
The method of claim 8 further including suspending adjacent said securing means and subjecting each of said additional assemblies to said agitation step before securing in said superposed relation.
Claim 11
Dependent Claim
11 words
The method of claim 1 in which said yarn is rayon.
Claim 12
Dependent Claim
27 words
The method of claim 10 further includes an additional step after said agitating step comprising heating said twisted loops to anneal said loops in the twisted position.
Claim 13
Dependent Claim
22 words
The method of claim 1 wherein the agitating of said assembly comprises movement of said array in a generally horizontal arcuate path.
