The body encircling portions of the blanks are composed of courses made with at least two stretch yarns, each of such courses being composed of conventional'knit stitches and a selected number of run-guard stitches that form in the inner side of the blank a vertical panel. The two panels are medially slit downwardly to a point-short of the lower ends thereof. The slit edges formed from each panel are connected either to one side of a crotch or panel portion or to the slit edges of the other panel, and in such manner that the unslit bottom portions of such panels are intermediate the ends of the crotch or panel portion, or the seam connecting such slit edges together. The vertical panel in each blank is at its top integral with a transverse band made of run-guard stitches and encircling the upper edge of the blank.
9 Claims, 5 Drawing Figures MANUFACTURE OF LADY'S PANTY HOSE THE INVENTION This invention relates to ladies Seamless sheer and heavy stockings of the type known as panty hose and which cover the legs and the lower trunk portion of the body of the wearer.
The present day panty hose type garment is usually formed by initially knitting on a seamless knitting machine a pair of separate stockings havingat their upper ends a circular extension which is used to make the hip covering portion or panty of the complete garment. In forming-the garment, the upper panty portions of the two stockings are slit longitudinally along their inner sides and the slit edges of the two stockings are connected together in part by' a crotch piece which may extend from the top rear edge of the garment and around the crotch to a point slightly above the latter at the front of the garment. At the front of the garment, the slit edges of the two stocking above such point are sewn together directly by a line of stitches which extends from such point to the top front edge of the garment.
The customary panty hose garment is usually made with a conventional stitch which is known to have a tendency to run. Further, the panty portion of the garment fits the lower trunk portion of the wearer very the garment runs which originate from the seam connecting the crotch piece to the conventional knit leg and body portions and especially which originate at the bottom of the crotch. In an effort to protect the panty hose from this tendency to run, it has become customary in the art to knit a circular row, usually about 1 inch wide, completely around each leg portion, using a runguard stitch, such as the known micro or Kant-run stitches. While these run. guards are effective to prevent runs in the legs of the panty hose, they have the disadvantage that they are clearly noticeable when the panty hose is worn, and are unsightly.
It is the primary purpose of the instant invention to provide a'panty hose construction which will prevent the formation of runs at the crotch piece.
A further object of the invention is to provide a panty hose construction which will protect the crotch area from running and which is not noticeable, or detractive of theappearance of the garment when the garment is worn.
Other objects of the invention as well as the advantages thereof will appear from the following description which should be read in connection with the accompanying drawings, in which FIG. 1 is a front elevational view of a panty hose provided with no run sections in accordance with the invention;
, FIG. 2 is a rear perspective view of the' garment shown in FIG. 1;
FIG. 3 is an inner side elevational view of a knitted stocking as it is produced by the knitting machine;
FIG. 4 is a view similar to FIG. 3 showing such stocking after it had been slit vertically in the upper end portion thereof; and I FIG. 5 is an elevation showing in enlarged detail the manner in which the split no-run sections are secured to the crotch section of the garment.
The garment shown in FIGS. 1 and 2 is composed of two stockings 10 and 11 each of which includesa leg portion 12 and an upper hip engaging portion 13. The hip engaging portions 13 of the two stockings are connected by a crotch piece 14 which is formed in the manner of a panel to provide added width to the hip portion 13 and which at the rear of the garment may, as shown, extend up to an elastic waist band member 15. At the front of the garment the panel portion 14 terminates at a point 16 located slightly above the crotch of the wearer. The two sides of the crotch piece or panel portion 14 are connected to the two opposed side edge portions of the stockings by two lines of stitches 17 and 18 which join at the point 16. From the point 16, the hip engaging portions 13 are connected at the front of the garment by a line of stitches 19 which extends up to the band member 15. In accordance with the invention, the connected side edge portions 20 and 21 of the hip engaging portions 13 are made with a run resistant stitch.
The two stockings 10 and 11 are circular knit stockings made separately on a conventional seamless knitting machine. The stockings are characterized by the fact that they are each completely knitted with a single yarn in forming the leg portions, hip engaging portions and the run-resistant portions thereof. As is customary in circularly knitting operations the stockings are made using two or a multiple of two cones provided with left and riht twisted stretch yarns which are alternately thrown to form the resulting product which is tubular in form as shown in FIGS. 3 and 4 of the drawings. The tubular product may be constructed to provide a foot part, as shown, or may be terminated in an ankle portion. Each tubular product, however, has a part 25 for the calf and thigh of the wearer, and a part 26 which is of such dimensions that when the two stockings are joined as shown in FIGS. 1 and 2 they may encircle the hips of the wearer. Each tubular product also has a run resistant section 27 extending longitudinally downwardly on the inner side thereof from a run resistant section 28 encircling the upper edge of the product. The section 27 extends down into the upper portion of the part 25, the upper extremity of such part 25 being indicated by the dotted line 29-29.
In knitting the tubular product, it is knitted as is customary from the top downwards to the desired end of such product which may be to provide a foot portion, as shown, in the usual manner. In the carrying out of such knitting operation one right and left twisted stretch yarn is used to construct the entire product, as has been previously indicated. The product is made using a conventional knitstitch except in the run resistant sections 27 and 28 which may be from k inch to 1 inch wide. Section 27 may be from 8 inches to 18 inches-long depending on the size of the garment. Initially, a number of courses of a known run-guard stitch is knitted to form the run resistant section 28 at the top of the garment. Then throughout the length of the run resistant section 27, the courses are knit in the following manner.
As previously stated, there is used in making the tubular product a standard type of seamless knitting machine provided with the usual pattern mechanism to knit a conventional mesh garment. In order to make the run resistant section, the machine is modified to substitute a group, say about 36, special needles in the'needle cylinder for a number of the needles which would ordinarily be employed to produce a conventional conventional knit stitch throughout the lengths of the courses. These special needles are constructed to knit a runguard stitch such as a'micro, or Kant-run stitch. During the knitting of each course, the thread is cleared of all needles except the special needles by means of a special cam arrangement which is associated with the main cam drum usually provided in such knitting machines and which is operable to activate one set of needles and to take the other set of needles out of operation. Thus, as the knitting machine normally operates in producing successive courses, the cams will activate those needles which produce the flat knit until the course reaches the no-run area 27, when the cams will operate to take such needles out of operation and activate the special needles for producing a run-guard stitch across the no-run area 27. When the special needles have knitted the no-run portion of the course, the cams again operate to place the conventional knit needles in operation and the special needles are deactivated. This is continued in the formation of each course until the desired length of no-run panel 27 is knitted,
when the drun and its associated cam arrangement will operate to terminate the construction of the panel 27 by the special needles and to enable the garment to be completed in regular fashion with each course being completely produced in conventional knit.
It will be observed that in construction the garment in the manner aforesaid, each course knitted throughout the length of the panel 27 will be composed of a length'of conventional knit and a length of run resist knit, and such two knits will be produced by the same single thread. Thus, in the two areas of conventional knit and run resist knit, the same thread will appear, thereby minimizing the differences in appearance between the two areas. It will also be understood that the width of the no-run panel 27 is regulated by the number of special needles which are used in making the same. Preferably, it is advisable to have the panel as narrow as possible without sacrifice of the reinforcement it affords. Thus, if the panel is narrow, it practically becomes invisible after'the crotch piece is sewed in place. Since this area of the garment is mainly between the legs of a wearer, it cannot be seen when in use.
When the tubular product is removed from theknitting machine it will be in the form shown in FIG. 3 of the drawings. Two tubular products such as shown in FIG. 3 are then slit vertically medially of the no-run panel 27 to a point short of its bottom end, i.e., approximately to'the line 29-29. Thus, if the product shown in FIGS. 3 and 4 is to be fashioned into the stocking shown in FIGS. 1 and 2, such slit will produce the two edge portions'20, 20 in FIGS. 1 and 2 and an unsevered bottom portion 30. In a similar manner, the slit in the other tubular product for making the stocking 11 will' when accomplished in accordance with this invention.
As the run-guard is in the nature of a vertical band, it tends to function as a guide for the operator performing the slitting operation. Because of this it becomes relatively easy for an operator to make a straight medial slit that will provide two separated edge portions 20, 20 of substantially equal width. This will in turn make it possible to produce straight seams l7, l8 and 19 when the parts of the garment are assembled.
In the assembly of the two tubular products which are finished in the customary fashion to provide the stockings 10 and 11, with the panel portion 14, the side edges of the latter are secured by the stitches of the seams 17 and 18 to the slit no-run edge portions 20, 21 so that the latters unsevered associated bottom portions 30, 31, respectively, are located intermediate the ends of the panel portion as shown in FIG. 5 of the drawings. Since, the length of the part of the no-run panel 27 that is slit is equal to the height of the hip portions 26, such bottom portions 30, 31 will be located at the bottom of the crotch in the assembled condition of the garment. In the construction illustrated the seams l7 and 18 will extend to and include one of the slit end portions of the no-run sections 28in the two stockings which will also thereby be connected to the side edges of the panel portion or piece 14. As previously explained, the two seams 17 and 18 join the seam 19 at the pointed end of the panel piece which is indicated by the point .16. Seam 19 extends up the front of the garment joining one slit side of the no-run edge portions 20, 21 and at the top of the garment theopposed other slit ends'of the no-run sections 28 in the two stockings. While in the embodiment illustrated, the rear portion of thepiece 14 extends up to the no-run section 28, it will be understood that in the use of other customary forms of crotch pieces the rear. portions thereof may terminate ina pointed end short of the no-' run section 28 in the manner of the front portion thereof. In such construction, the rear ends of the two seams 17 and 18 will merge into a single seam that extends from the rear termination of the crotch-piece to the no-run section 28 in the manner in which the front of the garment is assembled. It is also within the contemplation of the invention not to include a crotch or panel piece as is done in many present day panty hose constructions, and connect the slit edges of the no-run panel 27 directly together. It will be further understood that whichever construction is employed the micro or non-run knit in such connected slit edges of the panel 27 will prevent the creation of any runs from the seamed connections into the flat knit forming the panty portion and legs of the gannent. After the stockings and crotch piece are assembled a suitable stretchable waistband 1,5 is secured to the garment to finis the same.
