Abstract
INVISIBLY REINFORCED HOSIERY TOE
ABSTRACT
A method of knitting hosiery on a circular knitting machine and the hosiery so produced. A seam-less tube is rotary knit, the tube having leg, ankle, and foot portions, and the foot portion having a nude toe portion. A gradually decreasing stitch size is provided from the leg portion to the ankle portion for fit purposes. The fabric density in the toe portion is increased relative to the ankle portion by gradually decreasing the stitch size in the foot portion while maintaining substantially the same yarn weight. The resulting product has no line of demarca-tion since the increased fabric density is accom-plished very gradually and the toe has a wear life clearly superior to that of the normal "nude" toe, approaching that of a reinforced toe.

Description
6'7 INVISIBLY REINFORCED HOSIERY TOE
BACKGROUN~ AND SUMMARY OF THE INVENTION
It has long been known in the hosiery and pantyhose art that "nude" toe garments--that is, ~ 5 garments without any harsh visual transitions in the ¦ toe--sell much better than reinforced toe hosiery and pantyhose; however, it has also been well known in the art that "nude" garments wear out in a very short period of time relative to the normal wear life of reinforced toe hosiery and pantyhose, there-fore resulting in a product that is compromised.
According to the present invention, however, it is finally possible to provide "nude" toe garments having acceptable wear life--clearly superior to that of conventional "nude" ~arments--thus, combining the saleability of "nude" garments with acceptable wear ~ life.
! According to the present invention, it has ¦ been possible to provide garments with the saleability of "nude" garments and acceptable wear life by first ~, recognizing that reinforced hosiery and pantyhose are considered to be undesirable by most purchasers who prefer "nude" garments, not because of the opacity in the toe portion of the garment, but because of the clearly visible transition line between the reinforced portion and the rest of the foot, which is considered unattracti~e with open shoes. The present invention thus is directed toward eliminating any line of demar-cation in the foot area while still providing suffi-cient fabric densit~ (which necessarily has increasedopacity) in the toe area~ which i5 most prone to failure. Increased fabric density without a ., ~
,~ -.
~ demarcation line has been achieved according to the ; present invention by gradually decreasing the stitch size in the foot portion of the garment while main-taining substantially the same yarn weight. Because the increase in fabric density is gradual, no clear line of demarcation is provided, yet the wear life of , the toe portion is greatly increased compared to ¦ conventional "nude" garments.
i In the past~ gradual changes of stitch density in hosiery and pantyhose as well as other garments have been ~nown for fit purposes--see U. S. Patent Nos. 2,853,867 and 1,254,722 in particular. It is common practice between the knee and ankle portions of hosiery, where there is a major change in the average diameter of the leg, to gradually provide ¦ tighter stitches; however, heretofore there has not ¦ been any gradual tightening o~ the stitches from the ankle portion to the toe. The invention, for the first time, provides a gradual increase in fabric ~ 20 density in the forward portion of the ~oot and toe ¦ for the purpose of increased wear life, as opposed to fit purposes, and for the first time provides a gradual decrease in stitch size in the toe portion compared to the ankle portion by the gradual decreas-ing o~ stitch size in the forward part of the foot while maintaining substantially the same yarn weight.
~ ccording to the present invention, it is preferable to start a gradual decrease in stitch size from about the midpoint of the foot all the way throu~h the toe portion of the hosiery, although it is 3 not critical exactly wherein the foot portion the gradual stitch size decrease is initiated, as long as the results of no line of demarcation and increased fa~ric density in thP toe portion are accomplished.
6'7 ~ a~o~ce with a broad as ~ t, ~ inven~on relates to:
.~ A method of knitting hosiery or the like on ~ circular knitting machine, comprising the ; ~teps of:
I rotary knitting a seamless tube which `- comprises leg, ankle, and foot portions, the foot portion ha~ing a nude toe portion, by providing a gradually decreasing stitch size from the leg portion ~ to the ankle portion, and "f 10 increasing the fabric density in the toe portion of the tube compared to the ankle portion by gradually decreasing the stitch size in the foot . portion while maintaining yarn weight substantially constant, so that no line of demarcation as a result of increased fabric density is apparent in the foot portion yet the fabric density in the toe portion is much greater than in the ankle portion.
: In accor~e with a fI~r broad a~*, the invention relates to:
~ Hosiery or the like having leg, ankle and : foot portions, the foot portion including a nude toe portion, wherein the stitch size in said ankle portion is smaller than in said leg portion, and wherein the stitch size from said ankle portion to said toe portion gradually decreases so that no line of demarcation of areas of differing fabric densities is noticeable, but wherein the fabric density in said toe portion is substantially greater than in said ankle portion.
-2a-~ 7 ~` -3-It is the primary object o~ the present invention to provide hosiery and the like having no line of demarcation in the foot portion thereof, yet having increased fabric density compared to conven-tional "nude" hosiery and the like. This and theother objects of the invention will become clear from the inspection o~ the detailed description of the invention and from the appended claims.
BRIEF ~ESCRIPTION OF T~E DRAWINGS
FIGURE 1 is a schematic showing of an exemplary hosiery leg portion according to the invention;
FIGURE 2 is a side elevational view of the ankle and foot portion of hosiery according to the invention on a conventional examining form; and FIG~RES 3a and 3b are schematic showings of the cam arrangement in a Lonati and Reading Mark IV
conventional circular knitting machine, respectively, which provide exemplary manners for achieving the decreased stitch size in the foot portion according to the present invention.
DETAILED DESCRIPTION OF THE DRAWINGS
In the speci~ication and claims, the term "hosiery or the like" means hosiery, pantyhose, and like garments, in which a toe portion having increased wear life ~ut no line of demarcation is desirable.
Hosiery or the like according to the present invention is illustrated schematically in FIGURES 1 and 2, the hosiery having a leg portion 10, an ankle portion 12, a foot portion 14, and the ~oot portion 14 ha~ing a nude toe portion 16. As an inspection o~
EIGURES 1 and 2 makes clear, there is no clear line of demarcation in the foot portion 1~, although the _4_ ~2~
toe portion 16 will have increased fabric density . (opacity) compared to the ankle portion 12. The s increased fabric density in the toe portion 16 is substantially greater than in the ankle portion 12 S because during circular knitting of the garment the stitch size from the ankle portion 12 to the toe portion 16 gradually decreases. Most preferably, as .-indicated in FIGU~E 2, the stitch size is held con-stant from the ankle portion 12 to approximately the 10 middle 18 of foot portion 14, and then decreas!~s continuously and gradually from 18 to the toe portion 16. In FIGURE 2, this change in stitch size has been indicated by the diagrammatic showing referenced at 20, 24, 26 and 28. The stitch siz~ represented in ~-- 15 FIGURE 2 have been greatly exaggerated in size for clarity, the important point being that the stitches 28 are smaller in size than the stitches 26, which .~ in turn are smaller in size than the stitches 24, the transition in stitch size being made gradually; and - . 20 the stitches 28 are su~stantially smaller in size--- resulting in a substantial increase in the fabric density--than stitches 20.
While it is preferred that the gradual decrease in stitch size be initiated at approximately ~ 25 the middle 18 of the foot portion 14, to the toe por-tion 16, this is not critical, and the gradual decrease in stitch size can be effected anywhere from the ankle portion on down as long as the desired results of no clear line of demarcation with increased wear life relative to conventional "nude" garments are achie~ed. While any stitch size that accomplishes these resu~ts also is acceptable, some preferred - stitch size ranges will be set forth: for instance, the range of stitch size from the ankle portion to _ ~ t~
the toe portion preferably might be from approximately 1800 stitches per square inch to 2900 stitches per s~uare inch in the fully stretched out condition.
When the gradual decrease in stitch size is initiated S at the middle 18 of the foot portion 14, the range in stitch size from the middle 18 to the toe portion 16 is approximately 1800 stitches per square inch to ¦ 2900 stitches per square inch in the totally stretched ¦ out condition. In general, the density (stitches per ! lo unit area) in the area 16 of hosiery or the like j according to the present invention is increased approximately 65 percent compared to conventional I "nude" toe hosiery.
¦ In addition to providing the advantage~us 15 results mentioned above, the hosiery or the like pro-duced according to the present invention has some further advantages. Since the fabric density in the ball portion o~ the foot also will normally be increased--both with respect to conventional "nude"
20 garments and conventional reinforced toe garments--¦ depending on where the gradual increase in density is ¦ started, the wear life of the hosiery or the like should be increased for those individuals having a propensity to wear out the ball portion of the hosiery 25 first. Additionally, the present invention is parti~
cularly applicable to support hosiery or the like since the practice of the invention, thro~gh snug circumferential fit around the forward foot and toe area, alleviates excessive compression of the toes 3~ backward toward the foot, which compression frequently ~ results in complaints of cramping in conventional t support hosiery.
The gradual decrease in stitch size from the ankle 12 or foot 14 to the toe 16 according to the :' -present invention can be accomplished by a wide variety of simple modifications to existing knitting machines. For instance, the Reading Mark III, Reading Mark IV, and Lonati conventional knitting machines may be readily recammed in the size control area so that the graduator mechanism retains control of the stitch length throughout the ankle area and such that further graduation in the foot and toe area is available later on. One simple way for accomplish-ing this is by recamming the stitch length controlmechanism in such a way that only the first part of the graduator cam is used for the conventional graduation procedure (knee to ankle), the graduator cam and its associated setting screw retaining control all the way to the toe.
FIG~RE 3b illustrates how the Reading Mark IV
machine may he altered to practice the present inven-tion. The graduator cam 29 has an extra camming piece 30 added thereto, and the stitch length control block 31 that cooperates with the camming pieces 29, 30 is rearranged so that a single position controls both the foot and toe sections of the article being produced. The indexing pawl 32, the indexing roller cam 33, and the control arm 34 for the indexing pawl 32 are maintained substantially unchanged; however, the control drum 35 is modified by the addition of another cam 36 thereto. At position A of the drum 35, then, indexing for the ankle starts, at position B indexing for the ankle is stopped, at position C
indexing ~rom foot to toe is started, and at position D indexing for th~ toe is stopped. The shape and len~th of ~he camming piece 30 will, of course, con-trol exactl~ the nature of the graduations in the foot-toe area.
_7~ 7 ; FIGU~E 3a illustrates how the Lonati machine may be altered to practice the present invention.
The working cam 40, indexing pawl 41, indexing pawl control arm 42, and the graduating cam 43 remain , 5 substantially unaltered. Positions on the stitch length control block 44 are reallocated so that a separate position is provided for each of the toe and the ravel. A number of graduator activating links--shown in phantom line at 45 in FIGURE 3a--are removed from the control chain 46, so as to interrupt graduation between groups of graduator activating links shown as 47 and 48. The number of nonactivating links at 45, as well as the number of graduator activating links at 47 and/or 48, can be varied , 15 according to the style or size being produced. The group of links 47 controls the indexing from the knee to the foot, and the group of links 48 controls the indexing from the foot to the toe.
Y While the invention in its broadest concept 20 is not limited to any particular machine modification since a wide variety of simple machine modifications are available to those of ordinary skill in the art to accomplish the invention end results, the machine modifications illustrated in FIGURES 3a and 3b should 25 be eminently suitable.
Thus, it will be seen that according to the present invention, nude toe hosiery or the like having increased wear life have been provided, as well as a method for knitting such hosiery, therefore 3~ fulfilling a long felt need in the art. While the invention has here shown and described what is present~y conceived to be the most practical and preferred embodiment thereof, it will be apparent to those of ordinary skill in the art that many ~ 8~ r~ 7 modifications may be made thereof within the scope of the invention, which scope is to be accorded the broadest interpretation of the appended claims so as to encompass all equivalent methods and products.
