'Och 3, 1933. J' MARCUS CLOTH CONSTRUCTION Filed Jan. 14, 1953 /8 cfMfA/rf NVE'NTO? JACOB MARCUS 6W @MW Y csh/ENTE@ 8 ATTORNEY Patented Oct. 3, 1933 UNITED STATES PATENTv oFFlcE This invention relates to a fabric or cloth having overlapping portions secured together in a stitchless manner and also relates to the method of making the same.

One object ofthe invention is to provide a cloth having overlapping portions joined in a permanent manner without the necessity of employing a line of stitching for that purpose.

Heretofore it has been almost universal practice to fasten together overlapping portions of cloth bya sewing operation in which the thread punctures both portions to form interlocked loops. There are many instances, however, where the sewing together of the overlapping portions may be undesirable, as, for example, where the sewed cloth is subsequently required to be -stretched to the point where the stitching might be torn or broken; or where the sewed cloth when in use is so folded that cloth lying against the ridge formed by the stitching will be worn to the detriment of the cloth; or the type of cloth used may be such that it is liable to be torn due to the punctures therein due to the stitching.

In accordance with this invention the overlapping portions of cloth are held together by an adhesive such asa suitable liquid cement. In the preferred embodiment one or more threads are placed between the overlapping portions yand then the threads and the overlapped portions are cemented together, the special thread assisting in binding the cloth portions together after the adhesive has dried or hardened. This binding thread, however, should lie between the overlapped portions without puncturing either portion as is done when stitches are made.

It will also be frequently desirable to have the binding thread lie in a crooked or wavy path between the overlapped portions. This will increase the binding action and will also give more resiliency to the cloth so that when the cloth is stretched lengthwise of the cemented path the thread will merely tend to conform to a straighter path without breaking the bond between the joined portions.

A convenient method of manufacturing such an article is to immerse the thread in a liquid adhesive material, place the saturated thread between the portions of cloth to be overlapped and joined and then pressing the overlapped portions together to cause the adhesive to spread away from the thread between the overlapped portions.

The extent to which the adhesive will spread from the thread may be readily predetermined by the amount of adhesive originally applied to the thread and the amount of pressure employed in squeezing the adhesive out of the thread. The amount of pressure, for example, may be accurately regulated when the pressing operation is performed by calendering the'cloth.

This invention will be particularly described as embodied in a waistband lining for trousers which use is typical of-various embodiments in which the use of this invention would be advantageous. Such a waistband lining ordinarily employs a vstrip of stiiening material sewed to the lining strip proper and the two sewed strips subsequently sewed to the top of the trousers. In accordance with thisinvention the overlapping edge portions of the stiffening material and the lining are secured.without stitching by placing a thread vsaturated with liquid adhesive between the overlapping edge portions and then pressing the said portions together and drying the adhesive, as by calendering for example. The composite article so formed is then ready to be sewed to the top of the trousers to form the desired lining to the waistband.

This invention will be better understood by reference to the following detailed description taken in connection with the accompanying drawing in which,

Fig. 1 represents a sectional view of this invention as applied to a waistband lining for trousers;

Fig. 2 is a plan view partly in section of the waistband lining for trousers embodying this invention;

Fig. 3 is a plan view of the waistband lining prior to attachment to the trousers;

Fig. 4 is a sectional view of another form of lining embodyingthis invention; and

Fig. 5 is a sectional view of a third form of lining made from a single strip of cloth.

Referring more particularly to Figs. 1 to 3, the waistband lining of this invention comprises two strips of cloth cut on the bias, a stiffener member 6 and a lining member 7, the lining member being appreciably wider than the stiiener member. These strips may be of any suitable material, for example, the strip 6 may be of light weight canvas while the strip 'l may be any lining cloth such as mercerized cotton o r rayon. At the point 14, one edge portion of the lining element 7 is folded over the lower edge of the strip 6. Instead of securing the folded-over portion 16 to the strip 6 by a line of stitching it is cemented thereto by applying a suitable liquid cement between the parts and allowing the cement to dry or harden. Within this cemented area lies as independent thread 8 which lies in a flat spiral or wavy path extending along the entire cemented area in a direction roughly parallel to thefolded-over edge of strip 'L 'I'he preferred way of securing this adhesion between portion 16 and strip 6 is to immerse the thread 8 ln a suitable liquid cement until the thread absorbs the proper amount of cement after which it is promptly placed' between portion 16 and strip 6 and then pressure applied to force portion 16, strip 6 and thread 8 into close contact until the cement has dried. The application of pressure will, of course, cause the liquid cement to be partially forced out of the thread and spread over a narrow band of the cloth on either side of 'thread 8 `and thus increase the area of adhesion between the parts. -The principal attachment, however, between portion 16 and strip 6 is due to the thread 8 which is cemenied on one side to portion 16 and on its other side to strip 6, the thread 6 being partially buried in the opposing cloth faces due to the pressure employed in bringing the cloth faces together while drying the cement, as by calendering, for

example. l

As previously stated, the thread 8 is preferably placed in a flat spiral or wavy path between the fabrics to be joined instead of merely being placed in a straight path parallel to the edge of one of the cloth portions. It is frequently customary to stretch waistband linings in attaching them to the top of trousers. The lining of Fig. 2, for example, is given more resiliency due to the wavy path of thread 8 so that when the cloth is stretched lengthwise of the cemented path, the thread 8 will merely tend to conform to a straighter path without breaking the bond between thejoined cloth portions and without causing the thread 8 to be broken by the stretching force. This is particularly true when rubber cement is used around thread 8 and between the cloth portions, because such a cement even after drying is elastic and flexible, so that ,the joined portions containing thread 8 may be readily stretched and the cenient will stretch along with the cloth and the consequent straightening of thread 8 without damage to the band and the joined portions after such stretching will tendto return to its original form. That is the cemented cloth portions may be safely subjected to a pulling or stretching which would ruin cloth portions joined by the usual stitching.

It is to be noted that thread 8 does not form a lineof stitching which punctures both strip 6 and folded-over portion 16 but lies entirely between said strip and said portion along its entire path. Thread 8 may be of any desired size and material. For example, it may be of cotton, silk, or linen. For waistband linings it may have various sizes although cotton thread size has been found appropriate. This invention, however, is not limited to the use of a thread 8 of any particular size or shape nor is the invention limited to the use of a single thread between cloth portions to be joined since a plurality of spaced threads such as thread 8 may be used simultaneously.

The other edge portions of strips 6 and '7 preferably have edges which substantially coincide. If desired, these other edge portions may also be secured together by a cementing process accomplished by an independent thread 9 in the same manner as described above for the foldedover portion 16. Thus, as shown in Fig. 3 the thread 9 lies in a nat spiral path btwn me Lacasse edge por/tions of the two conveyed by thread 9 to ticularly adapted to be applied between the cloth portions by a thread previously immersed in the cement and by the use of such a thread a thinner coating of cement between the cloth portions can-be obtained than if the cement were a'pplied to the cloth by a brush for example. The

v'cement used should preferably be not brittle or applied in suillcient amount to appreciably thicken or stiien the fabric. Care must also be taken that the cement is not in sufficient amount to penetrate through the cloth portions and appear on their reversesides. Rubber cement does not harden but is elastic when it is dry. If a thick glue is employed there is dangojrthat any needle passing through the cemented portion' may get heated and cause frequent breakage of the sewing thread.

After the cement in and around threads 8 and 9 .has dried or hardened the completed waistband 330 lining shown lin Fig. 3 is-ready to be attached to the top of the trousers cloth as shown in Fig. 1. This may be accomplished by placing the outside face of lining 'i against the outside of the trousers cloth 11 and joining the two by a line of 115' stitching 10 where the stitching thread passes through the trousers cloth 11, the stiffener 6 and line 7, the lining strip and the trousers cloth being then folded back to present a seam as shown in Fig. 1. The lower portion 16 of'12o the lining may also be suitably fastened to the trousers. It is, of course, to be understood that the waistband lining of this invention may be attached to the trousers in any of a variety of ways by hand or machine of which Fig. 1 is merely one example.

In Fig. 1, elements 12 and 13 have nothing to do with the present invention sinceI element 13 is merely aV belt loop through which a belt 12 may be passed. y

Alternative forms of the waistband lining'for trousers are shown in Figs. 4 and 5. In Fig. 4 the lining strip 18 has edge portions folded over both edges of the stiiener strip 17. These edge portions are preferably cemented to the stiff-,135

ener strip 17 by the use of threads 19 and 20 in the same manner as previously described in connection with threads 8 and 9 of Fig. 3. The composite strip shown in Fig. 4 may be attached to the trousers in the manner shown in Fig. 1.

In the waistband lining of Fig. 5 no stiffener cloth is employed, the lining strip 2l having both its edge portions folded over on itself and cemented thereto by the use of threads 22, 23 in manner as described above for threads 8 and 9. The formed strip of Fig. 5 may be attachedto the top of the trousers in the same manner as in Fig. l.

It is to be understood 9; Vwide application in the garment industry or the same that this invention is inmensas other instances where formed fabrics are used and that the invention is not limited to a waistband lining for trousers. The invention is also capable of many varied embodiments as deilned in the appended claims. For example, the invention may be used in the manufacture of bellows for patch pockets or for sleeve interlinings.
