Abstract
Abstract A bobbin winding machine in which a plurality of individual strands are withdrawn from separate single end supply spools and guided to a location where they are simultaneously wrapped about the outer periphery of a metering wheel. The strands leave the metering wheel in the form of a band of contiguous strands of equal length which are then caused to pass through a positioning device that is effective in maintaining equal length of the individual strands from the band. The positioning device provides a line of pivot which is common to each of the strands during swinging movement of the band by a traversing apparatus spaced from the positioning device which includes elements mounted thereon for guiding and presenting the band to a rotatably driven bobbin for the purpose of building a band package thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
In a strand winding apparatus wherein a plurality of ends of strand material are drawn from individual supply spools, assembled into a flat band comprised of strand ends of equal length and wound through a traversing mechanism onto a collecting bobbin, the improvement comprising: (a) first means to receive said assembled flat band and rotate said band 90° from its original assembled position, and (b) second means associated with the traversing mechanism and traveling therewith to receive the rotated band and to rotate it to substantially the same relative angular position which it had upon initial assembly, whereby the flat band can be wound onto the collecting bobbin.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The strand winding apparatus according to claim 1 wherein said first means defines a first pair of juxtaposed rollers the axes of which extend perpendicular to the bands original assembled position.
Claim 4
Dependent Claim
42 words
The strand winding apparatus according to claim 2 wherein said pair of juxtaposed rollers provides a line of pivot for the band that is common to each of the ends thereof during reciprocable movement of said second means by the traversing mechanism.
Claim 5
Dependent Claim
38 words
The strand winding apparatus according to claim 2 wherein said second means includes a second pair of juxtaposed rollers the axes of which extend in the same direction as the axes of the rollers of said first means.
Claim 6
Dependent Claim
66 words
The strand winding apparatus according to claim 4 wherein said second means includes: (i) a flanged roller for receiving the band from said second pair of juxtaposed rollers and returning the same to its original assembled position; and (ii) a pivotably mounted beak member with means defining an internal channel for receiving the band from said flanged roller and guiding the band to the collecting bobbin.
Claim 7
Dependent Claim
53 words
The strand winding apparatus according to claim 4 wherein said second means includes a guide roller for engaging the band intermediate said first and second pairs of juxtaposed rollers with gear means for effecting simultaneous movement thereof in a plane parallel with and one-half the distance of said second pair of juxtaposed rollers.
Claim 8
Independent Claim
177 words
A method of winding a plurality of ends of strand material drawn from independent single-end supply spools, as a contiguous band of separate ends onto a rotatably driven bobbin while maintaining equal length of each end forming the band, said method including the steps of: (a) withdrawing each end simultaneously from their respective supply spools; (b) maintaining a pre-selected amount of tension on each of said ends during their withdrawal; (c) guiding the ends through a predetermined path of travel; (d) wrapping each of said ends simultaneously about the periphery of a metering wheel to form a band of contiguous ends of equal length; (e) rotating the band to travel in a plane normal to that at which it left the metering wheel; (f) moving the band to and fro along the length of the bobbin while traveling in the rotated path of travel; (g) rotating the band to its initial path of travel; and (h) feeding the band while moving to and fro to a rotatably driven bobbin for the building of a band package thereon.
