. .is capable of being packaged or wound on theretlcular kind of'material, for the purpose of illustration I have shown my invention asapplicable to the manufacture of strands of filaments formed of glass or equivalentinorganic materials.
In the manufacture of strands or filaments 'ofthe above general type, a plurality of streams of the selected material flow from a bushing having a given number of small orifices andthe streams thus formed are attenuated into filamentsbysuitable means and the filaments gathered tov gether into a single strand; The strand resulting from the above is usually wound into; a package on a revoluble; supporting member, which maybe also the attenuatingmeans, by traversing the strand along the member. closed, for instance, in the Fisher Patent No.

volu-ble member. It follows, therefore, thatin order to double the production at any one station it was necessary to duplicate all of the apparatus at this stationincluding the traversing equipment. This procedure is not only expensive but requires considerablev floor space and necessitates providing additional operators,
The present invention contemplates materially increasing the production at'any one station with out'duplicating the equipment by arranging the streams issuing from a single large bushing or a from a plurality of separate bushings into a plu-' rality of strands and by simultaneously winding the strands. on a single revoluble supporting member. r t
' 7 Another object of this invention is to individur ally wind the strands. on the-supporting member This process" is disin spaced relationship so that the windings of the individual strands are, in effect, independent of [one another and may be removedindividually from the revoluble supporting member. a

snarl the windings and interfere with further unwinding of-thestrand, and, because of the very small diameter of the individual filaments, are
These "ringers tangle and extremely diflicult to trace and remove, makingv it necessary oftentimes tofdisc'a'rd a'large portion of the package as a loss. r a
It'is an object of the present invention to provide a package of strands from which ringers areautomatically removed in the unwinding op v i accompanying drawings, wherein: i I Figure 1 is a diagrammatic side elevational view of a strand or filament producing apparatus con= vstructed in accordance with my invention;
eration. This is attainedby-winding a plurality of strands into a single package in such a manner that each of the strands in unwinding removes v any ringers left by the otherfstran'd'or strands. Thlsnovei winding also facilitates starting of unme at which the strand issuin'gfromthe bushing Its "Flgure1;' Figure 3 isa diagrammatic plan viewof the vide atraversin'g element having projections successively engageable with the strands to advance having the leading edges of the projections inclined ina direction. tov maintain the strands in. spacedrelation during the traversing movement.
with respect to the revoluble member to effect return travel of the strands -in an-out of phase relationshipduring the interval provided between engagement orthe strands by adjacent projections-on' the;traversingelement.
The foregoing, as well as other objects, will made more apparent as this description proceeds,
especially when consideredin connectionwith the .Figure' 2 is a front view for the. apparatus of apparatus shownin Figures 1 and 2 with the ex- I ception of the-bushing or feeder; and y a Figure 4 is -a diagrammatic plan view of a portionof'the'traversing equipment and of a. package woundin accordance with the present invention.
- 1A5 previouslystated, the-present invention, is
illustrated in: connection with the manufacture ofv continuous strands of of inorganic materials, such as glass or other materials having characteristics similar to glass; and is principally concerned with winding an improved package of the strands andincreasing the production of strands with the minimum amount of'equipment.
With the above in view referencewill Know be made to Figures 1 and 2 of the drawings wherein the reference character [0 indicates a bushing having laterally-spaced rows of orifices I I through 10.. which molten glassis caused lto'fiow continuously in the form of streams l2. Thestreams, l2
are attenuated to form filaments and the filaments are gathered into individual. strands l3 and I4 by suitable collecting guides and I6 respectively. In the present instance, the guides may include sizing pads which function to apply a; suitable lubricant to the surfaces of the glass farthest removed pad 15 to traverse along the package at a higher rate than the strand from the otherand nearer pad ll so that during return traverse the strands are out of phase. a By the invention two. continuous strands are ent invention renders it possible to at least double y the production without increasing the number of filaments and thereb protect the surfaces oithe,
filaments and bind each group of filaments into an integral strand.
The strands i3 and wound on a revoluble member I! in the form of a spool supported in any suitable manner for rotation about an axis I 8.- As a result of windin the two strands on the spool in accordance with the present invention, a package I9 is formed having two individual windings of strands which are capable of being removed as separate strands or, if desired, as one strand from the spool. In
M are simultaneously the furtherprocessing of the strands the two ends a right angle.
. pins 23 are preferably inclined from the periphe,
from one packagemay be twisted singly to form two yarns or twisted together to form a yarnof' 20 of the spool to theend 2i by a traversing disk" 22 supported for rotation about an axis perpendicular to the'axis of rotation of the spool and A having a plurality of circumferentially spaced projections in the form of pins 23 extending from the'periphery'thereof. The traversing disk is so located with respect to the spool i! that the pins 23 respectively engageboth strands and move the same from the end 20 of the spool to the opposite end 2! of the latter. It will, of course, be understood that the strands are released from their respective pins at points adjacent the end 2! of the spool I7 and are returned to the end ZObefore the next adjacent pin engage the strands. This return movement is efi'ected by positioning the guides or pads i5 and to outside the space bounded by planes normal to the axis of rotation of the spool and passing through the ends 2i], 2! of the spool or the ends of the package to be wound'on the spool. The arrangement is such that when the strands approach the end 2! of the spool they are under tension an will return toward the end 20 as soon as they are released due to their tendency to meet the spool axis at a It will be noted from the drawings that the ery of the disk 22 in a direction opposite the direction of rotation of the disk; This disposition of 'the pins 23 is preferred because it tends to maintain the strand in spaced relationship during traversing movement of the strands bythe pins, due to the angular relation between the pins and the surface of the package on the spool and machines or stations and without proportionately increasing the numberroi operators required.
.Figure 4 illustrates diagrammaticallythe type of package wound in accordance with the pres ent invention, and the relation thereto of a portion of. the traversing apparatus. The size' and spacing of the strands is exaggerated to more clearly illustrate the arrangementthereof on the packages The cycie'of winding depicted in this view begins at the point a. and under actionof the traversing disk the two strands l3 and- N are vspiraled about the package to the point I), with the strands in spaced relation due to the inclination of the strand-engaging projections'on I the' disk. The strands gradually approach each otheras they are traversed. along the. package due to the change in angular relation between the pins 23 and the package as the pins move along the package so that the strands are wound onthe package in out-oi-phase relationship. Depending upon the degree of inclination of the pins, the *strands may-come into actual contact at the end 2! of the package or may be slightly spaced or may cross each other. At the point D, the strands are releasedfrom the projections on the disk and return along the package under the influence of the oifset relation of the guides l5 and I8. 'Due to the greater distance that one of the guides, namely the guide I5, is spaced outwardly from the plane passing through the end' of'the package, the strand -l3 traverses along the package at a higher rate. This causes the space between the strands to increase as the strands approach the starting position on the a package, so that inefiect the strands on return traverse are also in out-of-phase relationship. From the fact that the strands come into contact or even cross each other at the end '2! of the package it can be seen that if substantially radially extending pins are employed in place of the pins 23 on the disk, the strands during the whole of the traversing movement under action of the pins will be in contacting relationand may even cross back and forth over each other'and will, in eifect, be wound on as a single strand. Although this arrangement of the strands is not as desirable as where traversing is effected byvv under action of the pins, or other traversing the relation of the package and pads illustrated in Figure 3.
The fact that the pads l5 and ii are offset from one another in the direction of the axis I8 of the mechanism that may be employed, are in spaced.
contacting, or crossing relation, theherein disclosed relation of the guides 15 and. I6 causes thestrands to wind on separately on return traverse in out-of phasereclaims.
