Abstract
Abstract A generally twistless yarnlike product is kept coherent by means of circumjacent polymer rings applied at intervals, high bulk being achieved by a loop effect as the filaments or fibres are differently contracted between the rings. To make such a product and similar products bound with rings, a bunch of fibres or filaments is temporarily brought in twisted and revolving state, and strips of a polymer in fluid state are spun around by means of the revolution of the bunch.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A yarnlike product formed of a plurality of filamentitious structures arranged in a substantially untwisted elongated coherent bundle, said bundle having at each of a plurality of spaced points along the length thereof a distinct applied band of solid polymer extending as a continuous ring around the periphery of a small localized compact section of the bundle and holding said structures in said coherent bundled relation, the intervening sections of said bundle between adjacent pairs of rings being substantially greater in length than said localized sections and having the filamentitious structures therein in loose unrestrained condition of substantially greater bulk than said compact sections.
Claim 2
Dependent Claim
104 words
A yarnlike product formed of a plurality of filamentitious structures arranged in a substantially untwisted elongated coherent bundle, said bundle having at each of a plurality of spaced points along the length thereof a distinct applied band of solid polymer extending as a continuous ring around the periphery of a small localized compact section of the bundle and holding said structures in said coherent bundled relation, the intervening sections of said bundle between adjacent pairs of rings being substantially greater in length than said localized sections and having the filamentitious structures therein in loose unrestrained condition of substantially greater bulk than said compact sections.
Claim 3
Dependent Claim
40 words
The product of claim 1 wherein some of the filamentitious structures in said intervening sections of said bundles are of a shorter length than the remainder of said structures whereby the latter assume a bulky condition between said polymer bands.
Claim 4
Dependent Claim
12 words
The product of claim 1 wherein said filamentitious structures are staple fibers.
Claim 5
Dependent Claim
30 words
A product according to claim 2 wherein said structures of shorter length are in the central region of the bundle and the remainder in the outer portion of the bundle.
Claim 6
Dependent Claim
23 words
A product according to claim 2 wherein the distribution of the shorter and the longer filamentitious structures is at random through the bundle.
Claim 7
Dependent Claim
22 words
A product according to claim 2 wherein the shorter filamentitious structures consist of an elastomer, and the longer ones are generally non-elastomeric.
Claim 8
Dependent Claim
27 words
A product according to claim 2 wherein the shorter filamentitious structures are crimped bicomponent fibres or filaments, and the longer filamentitious structures are mono-component fibres or filaments.
Claim 9
Dependent Claim
33 words
The product of claim 1 wherein said structures are crimped and some of said structures have a different degree of crimp from others thereof whereby the lesser crimped structures assume a bulky condition.
