Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
117 words
A false twisting device for thread, comprising: a rotatable elongate false twister member, a plurality of rollers rotatably mounted along respective axes paralleled to each other and to said member, said rollers bearing against said member at at least three axially spaced-apart locations therealong, a first said roller mounted along one of said axes being axially intermediate two said rollers mounted along another of said axes, said rollers bearing against said member in respective different radial directions whereby said member is axially and radially supported between said rollers, said first roller being radially displaceable relative to said two rollers, a magnet means integrally displaceable with said first roller and being positioned radially adjacent to said twister member.
Claim 2
Dependent Claim
117 words
A false twisting device for thread, comprising: a rotatable elongate false twister member, a plurality of rollers rotatably mounted along respective axes paralleled to each other and to said member, said rollers bearing against said member at at least three axially spaced-apart locations therealong, a first said roller mounted along one of said axes being axially intermediate two said rollers mounted along another of said axes, said rollers bearing against said member in respective different radial directions whereby said member is axially and radially supported between said rollers, said first roller being radially displaceable relative to said two rollers, a magnet means integrally displaceable with said first roller and being positioned radially adjacent to said twister member.
Claim 3
Dependent Claim
66 words
The device of claim 1, including two pairs of coplanar rollers, each pair being in a respective plane axially spaced apart from the other plane along the length of said member, the rollers in each pair being coaxial with respective rollers in the other pair, said member extending axially between said pairs of coplanar rollers, said first roller being axially intermediate said pairs of coplanar rollers.
Claim 4
Dependent Claim
28 words
The device of claim 1, said magnet means comprising a pair of flat magnets axially spaced apart along the length of said member on one radial side thereof.
Claim 5
Dependent Claim
41 words
The device of claim 3, said first roller having an operative position relative to said two rollers whereby said first roller urges said member against said two rollers and whereby magnets are radially separated from said member by an air gap.
Claim 6
Dependent Claim
45 words
The device of claim 3, said magnet means including a head of magnetically conductive material bridging the axial distance between said flat magnets along a radial side of said member opposite to said one radial side, said head being integrally displaceable with said flat magnets.
Claim 7
Dependent Claim
111 words
The device of claim 1, said first roller and said magnet means being mounted on a pivot arm, a resilient means urging said arm to a swung-in position which corresponds to said first roller bearing upon said twister member and urging same against said two rollers, said arm being pivotable against said urging to a swung-out position which corresponds to said first roller being radially displaced away from the aforementioned swung-in position whereby said twister member is free to displace radially away from said two rollers, said magnet means being adapted to hold saiD twister member in a fixed position relative to said first roller in the aforementioned swung-out position thereof.
Claim 8
Dependent Claim
26 words
The device of claim 1, at least one of said rollers being driven and thereby being adapted to drivingly rotate said member through surface-to-surface contact therewith.
Claim 9
Dependent Claim
43 words
The device of claim 3, including a pair of collars of magnetic material mounted on said member at an axial distance apart from each other in correspondence with the axial positions of said magnets, said collars being of larger diameter than said member.
Claim 10
Dependent Claim
11 words
The device of claim 8, said member being of nonmagnetic material.
