Abstract
Abstract A skeining machine has a looping member arranged to move in an elongated endless track having recurvate ends with a pair of looping needles arranged within said path to have a filament looped thereon during revolution of the looping member about the path with one of the needles being a spinner needle mounted on a rotatable shaft at an acute angle extending away from the other needle, and the spinner needle being disposed adjacent one of the recurvate ends of the looping member path and having the root of the connection between the spinner needle and the rotatable shaft on which it is mounted being disposed between the path of movement of the looping member and the center of recurvature of the looping member path.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
122 words
In a skeining machine having a looping member arranged to move in an elongated endless track having recurvate ends, and a pair of looping needles arranged within said path to have a filament looped thereon during revolution of the looping member about the path, one of said needles being a spinner needle mounted on a rotatable shaft at an acute angle extending away from the outer needle, and the spinner needle being disposed adjacent one of said recurvate ends of the looping member path, the invention characterized by the root of the connection between the spinner needle and the rotatable shaft being disposed between the path of movement of the looping member and the center of recurvature of the looping member path.
Claim 2
Dependent Claim
122 words
In a skeining machine having a looping member arranged to move in an elongated endless track having recurvate ends, and a pair of looping needles arranged within said path to have a filament looped thereon during revolution of the looping member about the path, one of said needles being a spinner needle mounted on a rotatable shaft at an acute angle extending away from the outer needle, and the spinner needle being disposed adjacent one of said recurvate ends of the looping member path, the invention characterized by the root of the connection between the spinner needle and the rotatable shaft being disposed between the path of movement of the looping member and the center of recurvature of the looping member path.
Claim 3
Dependent Claim
36 words
The invention defined in claim 1 wherein the root of the connection between the spinner needle and the rotatable shaft is disposed closer to the center of recurvature than to the path of looping member movement.
Claim 4
Dependent Claim
45 words
The invention defined in claim 1 wherein a filament source eyelet is provided adjacent the other recurvate end and is disposed in alignment with the looping element path and displaced from the centerline extending between the centers of recurvature of the looping member path ends.
Claim 5
Dependent Claim
38 words
The invention defined in claim 3 wherein the filament source eyelet is displaced to the opposite side of the centerline extending between the centers of recurvature ends of the looping member path from the other of said needles.
Claim 6
Dependent Claim
36 words
The invention defined in claim 3 wherein the root of the spinner needle and its rotatable shaft is displaced to the opposite side of the centerline extending between the recurvate ends of the looping member path.
Claim 7
Dependent Claim
36 words
The invention defined in claim 5 wherein the displacements of the root of the spinner needle and the filament source eyelet from the centerline extending between the recurvate ends of the looping member path are equal.
Claim 8
Dependent Claim
49 words
The invention defined by claim 3 wherein the filament source eyelet is in alignment with the path of travel of the looping element and located at a position before the looping element crosses the centerline extending through the centers of recurvature of the ends of the looping member path.
Claim 9
Dependent Claim
22 words
The invention defined by claim 1 wherein the radius of curvature of the opposite ends of the looping member path is dissimilar.
Claim 10
Dependent Claim
43 words
The invention defined by claim 8 wherein the radius of curvature of the recurvate end of the path of the looping member adjacent the spinner needle is less than the radius of the opposite recurvate end of the path of the looping member.
Claim 11
Dependent Claim
54 words
The invention defined in claim 1 wherein the looping member is mounted on an endless flexible drive element extending around an elongated track having recurvate ends, and drive means for the endless drive element disposed intermediate the recurvate ends of the track and engaging both of said oppositely moving spans to drive said element.
