Description
BACKGROUND

Articles of clothing commonly incorporate elastic bands. Additionally, many of these items with elastic also utilize a drawstring for pulling the clothing tightly around the body.

During manufacture, the incorporation of elastic and drawstring into an article of clothing currently includes several steps. Juxtaposition of the elastic and the material of the clothing occurs in the first step. The second step requires feeding a nonelastic drawstring through a channel created by affixing layers of the material together. This drawstring allows the wearer to tighten the clothing. Occasionally, the drawstring's end attach to the elastic or to the material of thus channel as a third step. As a result, the manufacturer, following this process to implant both elastic and a drawstring in an article of clothing, incurs appreciable production and labor costs.

Several problems normally arise with employing both elastic and a drawstring in this manner. Especially when situated within a channel created by creased layers of the material, the drawstring tends to lose its desired position. As the article of clothing receives wear, the elastic has a tendency to roll, entangling the drawstring. This enfolding of the elastic and displacement of the drawstring becomes cumbersome and uncomfortable for the wearer.

Further, pulling one end of the drawstring can cause the other end to enter the channel in the material and become lost. Carried to extremes, the cord completely separates from the article of clothing and possibly becomes lost. Thus, both the product and its method of manufacture have room for improvement.

SUMMARY

The use of an elastic band with an embedded pull cord eliminates several steps in the manufacture of an article of clothing employing a drawstring. The resulting simplified production realizes a reduction of manufacturing time and labor costs.

As usual, the elastic band includes an elongated web of material stretchable in its longitudinal direction. A substantially nonelastic pull cord extends along and intermeshes with the elastic web. The cord has an orientation along the web's longitudinal direction.

The pull cord should possess a length greater than the elastic band in its unstretched position. This excess provides a loop which the wearer may utilize as a pull cord to tighten the article of clothing. The ends of the cord may firmly attach to the band or the article of clothing incorporating the cord. The loop then forms at an intermediate position on the pull cord. The loop itself then has no ends which can become lost in the clothing itself.

The construction of the elastic band with its embedded pull cord generally requires the forming of an elongated web of elastic material. This materials shows its elastic properties in its longitudinal direction. The process then involves intermeshing a substantially nonelastic pull cord with a portion of the web of the elastic material. The pull cord extends in the longitudinal direction of the web. The cord must have a greater length than the portion of the web in which it finds itself embedded.

The elastic band with the embedded pull cord generally forms part of an article of clothing. The band adheres to the clothing around the perimeter defining an opening for the clothing such as its waist. The extra cord, drawn into a loop, acts as a drawstring for the piece of clothing.

The making of the clothing involves placing an elastic band in proximity to the opening's perimeter. The process continues with the affixing of the web to the cloth. This generally proceeds through the normal sewing. It could, alternatively, simply result from enclosing the band within a fold of the clock. Lastly, the process requires the intermeshing of the substantially nonelastic pull cord into a portion of the web. This step, however, may precede the affixation of the elastic web or band to the cloth.

Typically, the pull cord can form part of a woven, knitted, or braided elastic band. The cord may represent an integral thread of the band or an extra thread intermeshed with the band.

DETAILED DESCRIPTION

The pair of shorts 9 in FIG. 1 includes the elastic band to hold it around the wearer's waist. The shorts 9 also have the drawstring 12 to assure a tight fit.

As usual, the band lies adjacent to the perimeter 13 of the pant's waist opening 14. The layer 15 of folded material of the shorts 9 forms a channel 16 for the elastic band 10 with its string 12.

The elastic band 10, shown in FIG. 2, includes the woven elastic web 11. The pull cord 12 lies embedded within the band 10. The extra length of the cord 12 forms the loop 17. The wearer, by .[.pullling.]. .Iadd.pulling .Iaddend.on the loop 17, after .[.is.]. .Iadd.it .Iaddend.is cut in the middle, and subsequently tying a knot, may secure the pants 9 to herself.

As seen in FIGS. 3 and 4, the woven elastic band 10 results from the .[.intermeshing.]. .Iadd.interlacing .Iaddend.of the warp 18 with the woof 19. With the band 10 displaying its stretching qualities in its longitudinal direction, the warp threads 18 must also have an elastic composition. The woof 19 may also display elastic qualities, which would allow the stretching of the band 10 in its transverse direction. Most woven elastic, however, need only stretch in the former manner.

The pull cord 12 itself may have any typical construction. The figures suggest that the cord 12 has a structure resulting from the braided threads 21. However, almost any type of pull cord that finds use will suffice for the band 10. Generally, the cord 12 does not display elastic properties. Accordingly when the wearer tightens the loop 17 and forms a knot, the article will securely adhere to her. This would apply not only for the waist of pants, but also for the cuffs of either pants legs or sleeves as well as possibly the bottom of a jacket or shirt.

In .[.forcing.]. .Iadd.forming .Iaddend.the woven band 10, the machine places the elastic under tension as it effectuates the weaving process. As shown in FIGS. 3 and 4, however, the cord 12 represents one of the warp threads in the band 10. Furthermore, the machine includes the cord 12 with the elastic warp threads 18 under tension, or stretch. Releasing the tension on the band 10 after its manufacture permits it to contract. In other words, it loses part of its length. The .[.core.]. .Iadd.cord .Iaddend.12, not having an elastic nature, does not similarly contract. Rather, it compacts into little bunches along the band 10. This gives the cord 12 a greater length than the remainder of the elastic band 10 in its unstretched condition. Grabbing the cord 12 at some particular point and pulling it allows this extra length to form the loop 17 shown in FIGS. 1 and 2.

In forming the shorts 9 of FIG. 1, the manufacturer will grab the cord 12 at the opening 23 in the covering fold of material 15. Pulling the cord 12 through the opening 23 places the loop 17 at the particular location where the wearer can facilely make use of it. The task of pulling the extra cord 12 to form the loop 17 at the opening 23 represents a much easier and quicker task than threading a separate draw cord around the entire waist of the shorts 9.

Even with the loop 17, an excess amount of the pull cord 12 remains and forms .[.pleats.]. .Iadd.bunches .Iaddend.within the elastic band 10. Nonetheless, the loop 17 will have sufficient length to make it readily accessible to the wearer.

As stated above, the elastic band seen in FIGS. 1 to 4 results from a weaving process. The band 25 in FIG. 5 utilizes the threads 26 .[.intertwined.]. .Iadd.interloped .Iaddend.through the knitting process. The elastic band 25 includes the elongated stretchable fibers 27 which .[.provides.]. .Iadd.provide .Iaddend.it with its elastic qualities. The drawstring 28 also intermeshes with the knitted threads 26 to form part of the band 25.

Similarly, FIG. 6 shows the elastic band 31 formed from the threads 32 braided about the longitudinal elastic fibers 33. The pull cord 34 intermeshes with the fibers 33.

The elastic bands 25 and 31 in FIGS. 5 and 6, respectively, do not form under tension. Accordingly, simply releasing the tension does not result in the required excess of the pull cord 28. Rather, the machine that forms the bands 25 and 31 must insert greater amounts of the cords .[.27.]. .Iadd.28 .Iaddend.and 34 than the lengths of the respective bands would normally require. This produces the excess length resulting in the .[.pleated.]. .Iadd.bunched .Iaddend.cords 28 and 34. This additional length thus forms the loops which permit their use as drawstrings.

Furthermore, FIGS. 5 and 6 simply show the cords 28 and 34 as additional elements inserted into and intermeshed with the knitted and braided threads 26 and 32. For an appropriate style of knitting or braiding, the pull cords 28 and 34 could constitute one of the knitted or braided threads themselves.
