SU~MARY OF THE INVENTION
-In accordance with the method of the invention, a water-soluble substance is used as a wind stabilizing element
2~ in packages for oceanographic use. The water-soluble stabilizers dissolve when the package is immersed in water such that there . J f? C
is no need for physical ~emovement)of the stabilizers as there is in accordance with prior art packages. Wind packages stabilized in the manner of the invention would remain stabilized durins deployment from ships, for example.
The water-soluble stabilization segments are manu-factured in accordance with any type of molding that is adaptable to form polyvinyl alcohol, which is a water-soluble compound. The water-soluble stabilization segments could be injection molded, vacuum formed or cast. The actual method of forming the stabilization segments is not a significant aspect of the invention. Those having ordinary skill in the art to which the invention pertains would readily recognize the most expeditious manner of forming the water-soluble stabilization segments. Such water-soluble stabilization segments can be utilized in forming and packaging flexible material in a manner similar to that which is disclosed in U. S. Patent 3,803,796. However, it should be ap~arent that the scope of this invention is not limited to the specific method of packaging as disclosed in the aforementioned U. S.
Patent. The segments may be utilize,d with or without the use of cones, or with or without the use of shrink-wrap covering as disclosed in the aforementioned U. S. Patent.
The,significant feature of the invention is the use of water-soluble stabilizing segments in a package of flexible material of the universal type with a radial opening into the central axial opening of the winding through which the inner end of the material is drawn as the material is paid-out.

With reference to Figures 1 to 3, there is shown a shaft spindle 2 having a split end which can be enlarged as a threaded member, this being of well known type. Accord-ing to the invention/ a tube 4 lS slipped into spindle 2 and secured thereon. On tube 4 end members 6 are secured by set screws 8. These end members have suraces 10 outwardly curved in shape. Between these end members are segments 12 and 14, segments 12 being preferably formed of aluminum and segments 14 are pre-~ormed, water-soluble members. Each aluminum segment 7 has an annular extent of about 45 and each plastic segment extends approximately 75> Segments 12 and 14 have a main cylinder portion 16, downwardly or inwardly curved end portions 18 and flat ends 20 extending radially (see Figure 3). They are held in place by the fact that end members 10 slightly ~ ~'7.~.~3~ ~
o~7erlap .he cur~red portions 18 as shown at 22 in Figure
3.
The mandrel so formed is utilized in a winding machine having .~eans to move a guide for the flexible material back and forth along the mandrel slightly out of phase with the rotation of the spindle, while the varying relationship at one or more points in each layer forms a radial opening into the axial opening. This may for example be done as shown in Taylor U. S. Patent No.
2,767,938, whicn forms a so-called plus-minus.winding, and Patent No. 3,666,200.
~hen the package has reached the outer limit, that is the outer edges of end members 10, winding is stopped, tube 24 is inserted in the radial opening and inner end 26 of the material is drawn out from this tube.
Tube 4 is now released from spindle 2, and the assembled pzckage is moved to another spindle (Figure 4).
Be ore it is placed on the second spindle, one of the end members 10 is removed and lS replaced by annular member 28, preferably of plastic material, and having a central opening therein of slightly less diameter than the outer diameter Oc the flat ends 20 of the segments, and a backing member 30 which has pxotruding ~lange 32 fitting closely within the opening in .annular member 28 and an outwardly extending ring 2~ portion 3~, which can be secured in place by set screw 36.
Flange 32 p~o~ides proper centering for plastic annular member 28, and backing member 34 keeps the annular plastic member u?rish.. ~,s is shown in Figure 4, these parts are '7~
pushed on until flange 32 abuts against one of end faces 20 of segments 12,14, thus flattening the outwardly curved end wall of the package and placing it in a radial plane.
Tube 4 is now reversed on the spindle, the other end member 10 is removed and is replaced similarly by annular member 28 and backing member 30.
.
Now the resulting package is wrapped with a layer 38 of corrugated paper or the like, which is enclosed within a tubular member 40 of heat shrinkable plastic.
Heat is then ap?lied and the ends of the shrinkwrap 40 are brought around the outer edges of discs 2a. At the same time, a hole is maintained through wrappings 38 and 40 through which the inner end of~the material is brought out.
The package is now removed from tube 4 by loosening set screws 36 and backing members 30 are removed. Pre-formed water~soluble segments 14 are then secured by metal clips 42 which engage over end discs 28 of~ the package (Figure 5), belng bent down at the outer ends 44 to rest against the outer edges of disc 28 and which at their end inner ends are bent down at 46 to enter into openings in the ends OL segmer.ts 14. ~5etal segmrnts 12 are removed, which can be done throuoh the open end by pressing the ad~acent water-soluble segments outwardly.
Now there are inserted lnto the ends of the package a pair o cones 48 of the type shown generally in U. S. Paten' ~ ~'7~
No. 3,689,005. The upper ends of these cones, as shown in Figure 5, engage the inner walls of sesments 14 and thus push them against the inner su face of the wound mandrel.
The package is now ready for shipment. During shipment, the stability of the winding is maintained by the fact that the segments 14 are placed outwardly against its inner surface. When the package is to be used, there is no need to remove segments 14 as they will dissolve when immersed in water where the package is to be paid-out.
The shrink-wrap 40 may be removed from the packages prior to immersion in water to enhance the entry of water into the winding to dissolve the water-soluble stabilization segments.
Those skilled in the art will recognize that various modifications of the wound package may be made primarily in dependence upon the characteristics of the material being wound. For example, it may not be necessary to shrink-wrap the package, nor may it be necessary to pro~ide cones 48 which are normally used to prevent bir~-nesting as the material is unwound. It is also readily apparent to one of ordinary skill in the winding art that the water-soluble stabilization segments are useful with winding packages wound by methods other than that which is specifically disclosed herein.

Tube 4 is now released from spindle 2, and the assembled pzckage is moved to another spindle (Figure 4).
Be ore it is placed on the second spindle, one of the end members 10 is removed and lS replaced by annular member 28, preferably of plastic material, and having a central opening therein of slightly less diameter than the outer diameter Oc the flat ends 20 of the segments, and a backing member 30 which has pxotruding ~lange 32 fitting closely within the opening in .annular member 28 and an outwardly extending ring 2~ portion 3~, which can be secured in place by set screw 36.
Flange 32 p~o~ides proper centering for plastic annular member 28, and backing member 34 keeps the annular plastic member u?rish.. ~,s is shown in Figure 4, these parts are '7~
pushed on until flange 32 abuts against one of end faces 20 of segments 12,14, thus flattening the outwardly curved end wall of the package and placing it in a radial plane.
Tube 4 is now reversed on the spindle, the other end member 10 is removed and is replaced similarly by annular member 28 and backing member 30.
.
Now the resulting package is wrapped with a layer 38 of corrugated paper or the like, which is enclosed within a tubular member 40 of heat shrinkable plastic.
Heat is then ap?lied and the ends of the shrinkwrap 40 are brought around the outer edges of discs 2a. At the same time, a hole is maintained through wrappings 38 and 40 through which the inner end of~the material is brought out.
The package is now removed from tube 4 by loosening set screws 36 and backing members 30 are removed. Pre-formed water~soluble segments 14 are then secured by metal clips 42 which engage over end discs 28 of~ the package (Figure 5), belng bent down at the outer ends 44 to rest against the outer edges of disc 28 and which at their end inner ends are bent down at 46 to enter into openings in the ends OL segmer.ts 14. ~5etal segmrnts 12 are removed, which can be done throuoh the open end by pressing the ad~acent water-soluble segments outwardly.
Now there are inserted lnto the ends of the package a pair o cones 48 of the type shown generally in U. S. Paten' ~ ~'7~
No. 3,689,005. The upper ends of these cones, as shown in Figure 5, engage the inner walls of sesments 14 and thus push them against the inner su face of the wound mandrel.
The package is now ready for shipment. During shipment, the stability of the winding is maintained by the fact that the segments 14 are placed outwardly against its inner surface. When the package is to be used, there is no need to remove segments 14 as they will dissolve when immersed in water where the package is to be paid-out.
The shrink-wrap 40 may be removed from the packages prior to immersion in water to enhance the entry of water into the winding to dissolve the water-soluble stabilization segments.
Those skilled in the art will recognize that various modifications of the wound package may be made primarily in dependence upon the characteristics of the material being wound. For example, it may not be necessary to shrink-wrap the package, nor may it be necessary to pro~ide cones 48 which are normally used to prevent bir~-nesting as the material is unwound. It is also readily apparent to one of ordinary skill in the winding art that the water-soluble stabilization segments are useful with winding packages wound by methods other than that which is specifically disclosed herein.
