Claims
I claim:
1. The method of making an ornamental expansible strip which
comprises as a first step coiling stretched yarn about, in the same
direction and on opposite sides of a highly stretched elastic core,
relaxing the stretch on the core, thereby obtaining a core relaxed,
but under a retained low stretch and a yarn cover therefor the
strands of which are contracted and locked to the core, then
subjecting the core and cover, under a slight tension applied
thereto, to rotation in the same direction as the coiling of the
yarn strands to apply a twist to the combined core and cover,
thereby resulting in a combined core and cover, when relaxed,
possessing a retained low stretch and a stable twist with the yarn
cover tightly contracted on and locked to the elastic core.
2. The method of claim 1, wherein the yarn of the yarn cover is a
textured yarn.
3. The method of claim 2, wherein the textured yarn of the cover
comprises a plurality of yarn strands in each of the coiled
opposite sides of the elastic core.
4. The method of claim 1, wherein tautened tinsel strips are coiled
about in the same direction as the coiling of the yarn strands and
on opposite sides of the elastic core in the first step of the
method conjointly with the coiling of the stretched yarns about the
elastic core.
5. An ornamental expansible strip comprising a low-stretched
elastic core and an ornamental yarn cover embracing the same, the
yarn cover comprising yarn strands stretched and coiled about in
the same direction and on opposite sides of the elastic core, each
of the coiled strands being coiled about the stretched core, the
core and yarn cover combinedly possessing a stable twist, the yarn
cover being tightly wound, contracted on and locked to the
stretched and twisted elastic core.

Description
This invention relates to an ornamental expansible strip for use as
a yarn stretch gift package tie and as a decorative hair tie, and
to the method of making the same.
Decorative expansible strips are extensively used in the packaging
of gift boxes and are adapted for use for other purposes such as in
ladies coiffures as a decorator hair tie. They are made to comprise
an elastic, such as a rubber core provided with an ornamental yarn
cover, fabricated to possess when in relaxed or contracted form a
substantial extensibility, with the yarn cover tightly wound and
locked to the elastic core, the core being also preferably twisted
in its fabricated form, the resulting yarn cover being intended to
possess the characteristics of a uniform and fullness of
distribution on the core.
In the making of elastic strips according to prior methods, it was
found necessary after winding yarn about an elastic core to follow
this up by superimposing on the wound yarn a second layer of yarn
or a binding strip in order to prevent the kinking up of the yarn,
these steps being further so practiced as to introduce into the
resulting product a desired twist. The practicing of these separate
steps of the method was relatively difficult and complicated and
the resulting product did not possess the optimum uniformity of
distribution of the strands longitudinally of the core that was
desired.
The principal objects of my invention are the making of an
ornamental expansible strip possessing improved structural
characteristics such as the obtaining of a product in which the
yarn is distributed uniformly with the desired fullness and
straightness along the length of the elastic core, the product
having also a desired expansibility and contractibility, and
produced by a process, the practice of which may be carried out
with simplicity and effectively.
In fabricating the product of my invention, the yarn strands, in
the first step of the method are stretched and are coiled about a
highly stretched elastic core. Coiling the yarn and stretching the
same in coiling the same about in the same direction and on
opposite sides of the elastic core produces an intermixing of the
small texturized yarn employed which results in imparting the
desired substantial yarn fluffiness to the resulting product, in
also preventing curling and kinking of the yarns, as well as
facilitating the interlocking of the yarns one to another and to
the core. When the product of this first step is relaxed or
contracted, the core is under a retained low stretch, thereby
imparting to the product an inherent retained contractability, and
the yarn coils of the cover are distributed uniformly with a
desired fullness and straightness along the length of the core.
In the first step of the method, and to impart to the product an
added ornamental feature, tautened metallic, such as tinsel strips
are wound and also preferably coiled about in the same direction as
the coiling of the yarn strands and on opposite sides of the core
together with the coiling of the stretched yarn. In the resulting
product, the tinsel strips are projected out by the relaxed
stretched yarn coils and are rendered desirably surface
visible.
In a second step of the method, the yarn and tinsel covered elastic
core, under a slight tension applied thereto, is rotated to impart
a permanent (stable) twist to the product. This further aids in
securing an interlock of the full yarn strands and metal tinsel
strips to the elastic core and also results in straightening out
and longitudinally aligning the strand coils on the elastic
core.
To the accomplishment of the foregoing objects and such other
objects as may hereinafter appear, my invention relates to the
ornamental expansible strip product as sought to be defined in the
appended claims, taken together with the following description and
the accompanying drawings, in which:
FIG. 1 is a view of the first step in the method of fabricating the
ornamental expansible strip product of the invention, with suitable
legends applied explanatory of the practice of this step of the
method;
FIG. 2 is a view of the product obtained from the first step of the
method, with legends applied thereto explanatory of the structural
characteristics of the product thus obtained;
FIG. 3 is a view depicting the second step of the method of
fabricating the product, with legends applied thereto explanatory
of the practice of this second step of the method; and
FIG. 4 is a view of the final fabricated product as obtained in the
second step of the method shown in FIG. 3, with legends applied
depicting structural and use characteristics of the end or final
product thus obtained from the said second step of the method.
Referring now more in detail to the drawings, I shall first make
reference to FIGS. 1 to 3 thereof, which depict and explain the
steps of the method of fabricating the ornamental expansible strip
product.
In the first step of the method shown in FIG. 1, yarn strands 10
and 12 are stretched and are coiled about in the same direction and
on opposite sides of a highly stretched elastic core 14. The yarn
is a texturized yarn which may be of any fabric material and is
preferably nylon. The yarns 10 and 12 are coiled tightly about the
rubber core 14, which latter is under tension being stretched
approximately five times its normal length. Conjointly with the
coiling of the yarns 10 and 12, there is also coiled tightly about
the elastic core 15 and in the same direction as the coiling of the
elastic core tautened metallic strips (such as tinsel strips) 16
and 18, preferably made of Mylar. While the yarns 10 and 12 are
indicated as single strands of yarn, I employ a plurality of
strands of yarn for each side of the coiled assembly. In practice,
I prefer to use eight carriers of yarn and tinsel strips in two
sets of four, six carriers having the texturized yarn and two
carriers having the tinsel strips.
The legendary matter to FIG. 1 of the drawings is explanatory of
this described practice of the first step of the method. The
elastic core 14 is under tension as indicated by the arrows a, a,
the texturized yarn 10 and 12 is under stretch, as indicated by the
arrows b, b, the tinsel strips 16 and 18 being tautened, is
indicated by the arrows c, c, the direction of the attachment of
the cover combination to the elastic core is indicated by the arrow
d.
FIG. 2 shows the relaxed product of the first step of the method of
FIG. 1, this product being wound on reels or spools for the
practice of the second step of the method. The product shown in
FIG. 2 depicts the yarn strands 10 and 12 relaxed, bunched and
locked to the elastic core 14 and the tinsel strands 16 and 18 in
their relaxed condition, this combination forming the cover of the
core. The yarn strands and the tinsel strands at this stage of the
method are bunched and locked to the core in the manner illustrated
in the figure. The core 14, although relaxed, is under a low
stretch, the same having a retained low stretch about twice the
normal length of the rubber core. As a result of the interrelated
tensions of the now relaxed yarn strands and the low stretch of the
elastic core, the core remaining under low tension by the radial
pressure of the braided yarn biting into the same, the yarn strands
are caused to be bunched together into closely interlocking coils
20 and 22 evenly distributed along the length of the low stretch
core. The tinsel strands 16 and 18 are projected out by the relaxed
stretched yarn coils 20, 22 and these are thereby rendered more
visible along the surface of the resulting product, thereby
enhancing the ornamental character of the product.
In the second step of the method, depicted in FIG. 3, the core and
cover product of FIG. 2, now generally designated in combination as
24, wound on a reel or spool 26, and mounted on a support 28, is
put at its open end under a slight tension as indicated by the
arrow e; and the core and cover product is rotated in the same
direction as the coiling of the yarn strands (as indicated in FIG.
4) by rotating the support 26 by means of a motor 30; and from the
reel or spool 26, the core and cover product 24, is fed through a
tube 32, and through and by a set of rollers 34. The result of this
operation is to impart a slight twist to the rubber core and its
cover as indicated by the character 36. This twist remains as a
permanent or stable twist in the resulting product. The twist in
the product aids in securing the desired interlock of the yarn
strands and the metal tinsel strips to the elastic core and also
results in straightening out and longitudinally aligning the strand
coils 20 and 22 on the elastic core.
FIG. 4 shows the end fabricated product as resulting from the
second step of the method (FIG. 3). As shown in this end product,
the elastic core 14 is characterized by a retained twist, the core
also retaining its low stretch in the manner above described. The
now relaxed yarn 10 and 12, with the interspersed tinsel strips 16
and 18, tightly wound, contracted on and locked to a stretched and
twisted elastic core, yields a fabricated product, which in
addition to the structural and use characteristics described, is
characterized by yarn coils which are distributed uniformly with
the desired fullness and straightness along the length of the
elastic core, as sought to be illustrated in FIG. 4 of the
drawings.
The method of making the product of the invention is considerably
simplified with relation to prior art methods in that by coiling
yarn strands in a stretched condition and coiling the same about
the stretched elastic core in a single method step results in
obtaining a yarn cover the strands of which are securely locked to
the core when contracted after the practice of this first step and
the coils of the yarn are effectively and uniformly distributed
along the length of the product. With the simultaneous and conjoint
coiling of the tinsel strips onto the assembly in this step of the
method, the product is highly ornamented by the loops of the tinsel
strip extending to the exterior of the formed product. The second
step of the method may be practiced with facility and this latter
step is used merely to introduce a permanent twist to the product
with the result of aiding in securing the interlock of the yarn
strands and the metal strips to the elastic core and in adding in
straightening out and longitudinally aligning the strand coils to
the elastic strip. There results from this method the structural
characteristics of the product as described.
It will be apparent that changes may be made in the materials
employed and the practices of the steps of the method described,
without departing from the spirit of the invention in the following
claims.
