Abstract
Abstract A device for winding textile threads in which the clamping spindle, upon which a bobbin cylinder is mounted, extends with its ends beyond the bobbin and loosely engages with annular grooves in these ends the circumferences of two pairs of circular supporting discs, each pair of which is mounted on a horizontal shaft, whereby these two shafts are parallel and spaced from each other and are arranged in the same horizontal plane. A motordriven cylindrical roll is arranged above the bobbin cylinder and frictionally engages the same and later the bobbin formed by the thread which is conducted from above by a horizontally reciprocating thread guide-along a portion of the circumference of the cylindrical roll-and then onto said bobbin cylinder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
In a filament winding device, a frame, first and second rollers rotatably supported by said frame in side by side parallel relationship, a radially projecting circular end flange at each end of each of said first and second rollers, a third roller of cylindrical shape rotatably supported by said frame with the axis of rotation of said third roller parallel with the axes of rotation of said first and second rollers and in such a position that a plane containing the axis of said third roller intersects a plane containing the axes of said first and second rollers substantially midway between said first and second rollers, a bobbin for receiving the filament, centrally disposed axle means projecting from each end of said bobbin and each provided with a circumferential groove of a width substantially equal to the thickness of one of said circular end flanges on said first and second rollers whereby said bobbin may be supported on said first and second rollers with said flanges in engagement with said grooves, interengaging guide means on said frame and said third roller constraining said third roller to slidable movement toward and from said plane containing the axes of said first and second rollers whereby said third roller is movable toward and from said bobbin supported on said flanges, drive means for rotating one of said first, second and third rollers and thereby rotating the other two rollers and said bobbin by frictional interengagement, and filament guide means mounted for reciprocatory movement longitudinally of said bobbin.
Claim 2
Dependent Claim
254 words
In a filament winding device, a frame, first and second rollers rotatably supported by said frame in side by side parallel relationship, a radially projecting circular end flange at each end of each of said first and second rollers, a third roller of cylindrical shape rotatably supported by said frame with the axis of rotation of said third roller parallel with the axes of rotation of said first and second rollers and in such a position that a plane containing the axis of said third roller intersects a plane containing the axes of said first and second rollers substantially midway between said first and second rollers, a bobbin for receiving the filament, centrally disposed axle means projecting from each end of said bobbin and each provided with a circumferential groove of a width substantially equal to the thickness of one of said circular end flanges on said first and second rollers whereby said bobbin may be supported on said first and second rollers with said flanges in engagement with said grooves, interengaging guide means on said frame and said third roller constraining said third roller to slidable movement toward and from said plane containing the axes of said first and second rollers whereby said third roller is movable toward and from said bobbin supported on said flanges, drive means for rotating one of said first, second and third rollers and thereby rotating the other two rollers and said bobbin by frictional interengagement, and filament guide means mounted for reciprocatory movement longitudinally of said bobbin.
Claim 3
Dependent Claim
35 words
A device according to claim 1, in which said first, second and third rollers are horizontally disposed and said interengaging guide means for the third roller are adapted for vertical movement of said third roller.
Claim 4
Dependent Claim
21 words
A device according to claim 1, in which said first, second and third rollers are rotatably supported at one end only.
Claim 5
Dependent Claim
32 words
A device according to claim 1, in which said third roller and the end flanges of said first and second rollers have diameters which are substantially greater than that of said bobbin.
Claim 6
Dependent Claim
27 words
A device according to claim 1, in which said projecting axle means form parts of a bobbin pin on which a cylindrical bobbin sleeve is removably mounted.
Claim 7
Dependent Claim
31 words
A device according to claim 5, in which said third roller is longer than said cylindrical bobbin sleeve and extends beyond the ends of said bobbin sleeve at both ends thereof.
Claim 8
Dependent Claim
18 words
A device according to claim 1, in which said drive means is operatively connected with said third roller.
