SEAMLESS PI powcAsE AND FABRIC 2 Sheets-Sheet 2 Filed Oct. 3, 1961 United States Patent 3,155,121 SEAR LESS PEJLOWCASE AND FABREQ Norman L. Seltzer, Princeton, NJ and Charles R. Higgins, Charlotte, Natl, assignors to The Kendall Com-- pany, Boston, Mass, a cerporatinn of Massachusetts Filed Oct. 3, 1961, Ser. No. 142,666 11 Claims. (Cl. 139-389) The present invention relates to woven textile fabrics and more particularly to a woven textile fabric which may be formed into tubular blanks closed at one end and open at the other end merely by a severing operation, the blanks when everted being particularly adaptable as a pillowcase.

Conventionally, pillowcases have been formed by many dilferent methods. One of these methods comprises the steps of severing a single layer textile fabric into blanks of a length slightly greater than the desired length of the finished pillowcase and a width substantially equal to twice the desired width of the finished pillowcase. These blanks are usually severed in stacks with a large number of blanks being formed simultaneously. One of these severed blanks is removed from the stack and a sewing machine operator folds the blank widthwise and stitches the folded fabric layers together adjacent the side edge opposite the fold line and adjacent one end. The stitched blank is then hemmed at the open end, opposite the stitched end, and everted to provide a finished pillowcase. A second method is similar to the one described above, but the blanks are severed with a length and width substantially equal to the desired length and width of a finished pillowcase and a pair of the blanks are stitched together adjacent both sides edges and adjacent one end. In this method, the stitched blanks are hemmed and then everted as in the first method described above.

A third conventional method of forming a pillowcase comprises the steps of weaving the fabric of which the pillowcase is to be formed in tubular form with a width equal to the desired width of the finished pillowcase. The tubular fabric is severed into blanks of a length slightly greater than the desired length of a finished pillowcase and the layers of the tubular blank are stitched together adjacent one end. The blank is then hemmed and everted as in the methods described above to present the same as a finished pillowcase ready for use.

To satisfactorily perform these operations, the stitching and hemming operators are necessarily required to exercise considerable care and skill in handling the blank or blanks to assure proper formation of the pillowcase with straight uniform stitching and an even hem. It is apparent that such operations are tedious and result in both mental and physical fatigue of the operator. Also, the requirement that the stitching be in a straight line and that the hem be folded over evenly necessitates using highly trained, skilled operators. It is self evident that these many tedious operations in forming conventional pillowcases account for a considerable portion of the cost thereof.

It is an object of the present invention to provide an interwoven tubular pillowcase which provides substantially the same outward appearance as a conventionally stitched and hemmed pillowcase, but wherein the manner of interweaving the pillowcase obviates the necessity of the tedious steps of stitching and hemming.

A further object of the present invention is to provide a woven pillowcase of the character last described having a relatively narrow transversely extending band adjacent the open end thereof, the band providing an appearance simulating a hem.

Another object of the present invention is to provide a woven textile fabric of indefinite length comprising a plurality of interconnected tubular blanks which merely need to be separated from each other by a severing operation and then everted to present the same as pillowcases ready for use having substantially the same outward appearance as conventionally stitched and hemmed pillowcases.

A more specific object of the present invention is to provide a woven textile fabric of indefinite length comprising a plurality of juxtapositioned interconnected elongate panels, alternate panels being considerably wider than intervening panels, each of said panels comprising a pair of independent fabric layers, the layers of said alternate panels being interwoven only at one end and along the longitudinal edges, the layers of said intervening panels being interwoven at both ends and along the longitudinal edges, said intervening panels being adapted to be longitudinally severed in a medial portion to separate the alternate panels from each other into pillowcase blanks, said blanks when everted providing seamless pillowcases ready for use having substantially the same outward appearance as conventionally stitched and hemmed pillowcases.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which- FIGURE 1 is an isometric view of a length of fabric embodying the features of the present invention;

FIGURE 2 is an enlarged plan view of a tubular blank severed from the fabric shown in FIGURE 1;

FIGURE 3 is an enlarged isometric view of the blank shown in FIGURE 2 with portions broken away;

FIGURE 4 is an isometric view of a pillowcase ready for use formed by everting the blank shown in FIG- URE 2; 1

FIGURE 5 is an enlarged detail with a portion broken away of the fabric within the blocked area 5 in FIGURE 2; and

FIGURE 6 is an enlarged fragmentary section taken substantially along line 66 in FIGURE 3 and corresponding to the detail shown in FIGURE 5.

Referring now to the drawings, and particularly to FIGURE 1, a woven fabric 10 is illustrated in the condition in which the same is removed from the loom. As shown, the fabric 10 comprises a plurality of elongate interconnected panels 11 and 12 serially arranged in alternation in a warpwise direction. As shown, the panels 11 and 12 extend lengthwise in a fillingwise direction and are of uniform length.

Each of the alternate panels 11 defines the body portion of a pillowcase blank 29 (FIGURE 2), and are formed of suflicient length and width to receive the desired size of pillow therein. The intervening panels 12 define pinking bar portions on opposite sides of the alternate panels 11 and are adapted to be longitudinally severed, preferably by pinking, as indicated at 13 in FIGURE 2, in a medial portion to separate alternate panels 11 from each other. Panels 12 are therefore formed of only sufficient Width to allow the same to be longitudinally pinked and to provide the desired antiravel characteristics.

Panels 11 and 12 each comprise a pair of

independent fabric layers

14, 15, and 15, 17 respectively. These fabric layers are interwoven together and to each other along the adjacent longitudinal edges of panels 11, 12 to connect the panels together along spaced lines 21. Lines 21 are preferably formed by a conventional pinch pick mechanism wherein the filling yarns, in a range of from four (4) to ten (10), with six (6) being preferred, are interwoven With all of the warp yarns which go to make up the

layers

14, 15, and 16, 17.

The interweaving of layers 14, 15 together along lines 21 serves to form alternate panel 11 into tubular form and the interweaving thereof at one end forms a closed end which obviates the necessity of a stitching operation. The layers 14, 15 at the other end remain separated to form an open end defining tne opening of the pillowcase.

Layers

16, 17 of intervening pinking bar panels 12 are interwoven at both ends to form closed ends to provide a reinforcement for all the cornersvof the illowcase and to increase the anti-ravel characteristics.

In the preferred embodiment shown, both ends of panels 11, 12 are bounded by opposite selvages 22, 23 of fabric ll). It is contemplated, however, that two sets of panels ll, 12 may be woven simultaneously if the width of the loom being used will accommodate the same. In the fabric shown, selvage 23 preferably is formed of plied or pairs of warp yarns W, (FIGURE which are interwoven with filling yarns F in a plain weave design. Opposite selvage 22 is formed in a similar manner. The open end of a panel 11 is formed by inserting two successive picks of filling yarns in layer 14 and then two successive picks in layer 15, with the shuttle initiating and terminating adjacent selvage 22 for each pair of picks. Thus, the filling yarn is changed from one layer to the other on the side of the fabric bounded by selvage 22 which forms the closed end of the panel 11.

A relatively narrow band portion 24 extends transversely or warpwise of the fabric layers adjacent the open end of the pillowcase in substantially the same relative position as a hem on a conventionally stitched and hemmed pillowcase. Band portion 24 has different characteristics from the remaining portion of the fabric layers to provide a visual appearance which simulates a conventionally formed hem. It is contemplated within the scope of the present invention that the aforementioned different characteristics may take any one or a combination of many different forms. For example, these different characteristics may be differences in the manner of interlacing of the yarns, in yarn density including a larger yarn size or a greater number of yarns per inch, or any other means which renders band 2-4 distinctive from the remaining portion of the fabric layers.

Preferably, band 24 comprises a first band portion 25 immediately adjacent the open end of the pillowcase, and a second hand portion 26 disposed in juxtaposed relation thereto remote from the open end of the pillowcase. Second hand portion 26 comprises a narrow strip of fabric delineated from first band portion 25 and the remaining portion of the fabric layers by spaced, parallel shadow lines 3%, 31, respectively.

Shadow lines

30, 31 preferably comprise thin places in the fabric layers and result from the omission of the warp yarns W in this area as by leaving three dents in the loom reed corresponding to this area of the fabric vacant.

A pair of spaced,

parallel lines

32, 33 are provided in second band portion 26 between and parallel to shadow lines 3%, 31.

Lines

32, 33 are preferably formed by providing a plurality of warp yarns W, preferably five (5), bunched together and interwoven with the filling yarns F as one yarn to provide an appearance simulating spaced lines of stitching which combine with the shadow lines 349, 31, and the remaining portion of second band portion 26 to simulate a seam corresponding to the seam of a conventionally hemmed pillowcase. It is contemplated, however, that

lines

32, 33 may be formed by any means which will cause the same to be visually distinctive. For example, these lines may be formed of a single warp yarn of considerable larger size than the remaining warp yarns.

A small area 27, (FIGURE 5), of the fabric layers on the side of shadow line 321 remote from the open end of the pillowcase is formed with a greater number of warp yarns per inch than the adjacent fabric portions to strengthen the fabric in the area of the shadow line. It is noted that area 27 also serves to make shadow line 31 more distinctive.

The band 24 is preferably formed with a greater number of warp yarns per inch than the remaining portion of the fabric to provide a greater yarn density which provides an appearance simulating the folded-over por tions of a conventionally hemmed pillowcase. In this regard, the yarn count for both warp and filling yarns throughout each of the layers may be within a range of 22 to 38, with 26 being preferred for the warp yarns and 2'i /2 being preferred for the filling yarns. The filling yarns throughout each of the fabric layers may be within a range from to 85 picks per inch with 64 picks per inch being preferred. The warp yarns in the band portion of each of the layers may be within a range from 75 to 135 ends per inch with 96 ends per inch being preferred, and, in the remaining portion of each of the layers, the warp yarns may be within a range from to 90 ends per inch with 72 ends per inch being preferred.

Blank 2t), when separated from the other blanks em- 7 bodied in fabric lit by the longitudinal pinking of panels 12, needs only to be everted to present the same as a finished pillowcase it (FIGURE 4), ready for use. It is noted that, in pillowcase 40, pinked panels 12 are disposed inside the pillowcase as is clearly shown in FIGURE 4. Also, in pillowcase 4t), lines 21 provide an appearance closely simulating the side stitching of a conventionally formed pillowcase and, as aforementioned, band portion 24 simulates a hem of such a conventional pillowcase.

It is therefore apparent that a novel seamless pillowcase is provided which is formed by interweaving warp and filling yarns to provide serially arranged tubular pillowcase blanks, which blanks need only to be separated by a severing operation and then everted to provide a finished seamless pillowcase ready for use having substantially the same outward appearance as a conventionally stitched and hemmed pillowcase.
