METHOD or MAKING COLLARS AND LIKE' ARTICLES.

' Application filed June 17, 192 2. Serial No. 569,016.

Be it known that LCHAnLns A. HoR'roN,

. a citizen of the United States,-residing at Providence, in the county of Providence and State of Rhode Island, have, invented certain new and useful Improvements in Methods of Making Collars and like Articles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the manufacture of articles of cloth that are of non-rectangular outline, and particularly to the fabrica tion of collars or like articles that are curved in the plane of the cloth when flattened out.

It has been heretofore proposed to make folded collars of one piece of fabric curved in the weaving operation and having a curvilinear, weakened fold line. In the patent to Morgan, No. 1,254,340, dated January 22, 1918, there is disclosed a foldedcollar made of one piece of multiply interwoven fabric, which has been woven in a continuous curve by feeding the' 'warp threads, or groups of them, progressively fast-er proceedingfrom the concave to the convex edge, said collar having a fold line or zone that is weaker than the remainder of the fabric. From cloth so woven onepiece folding collars may be made of sufiicient stiffness to retain their form without the necessity of starching. These collars fit the neck properly because of the-curva the neck band portion and outer panel-be ing overlapped and stitched together at one edge. One example of a two piece folding collar thus constructed is disclosed in patent to Van Heusen 1,309,379, dated July 8,

Webbing, the warp threads of which curve in the plane thereof (when the webbing is flattened out) can be readily woven on narrow ware or webbing looms as described in said patent to Morgan No. 1,254,340. An ordinary webbing loom may be adapted to produce webbing with a curvilinear warp by equipping it with a set of conical take-up rolls and a conical or inclined guide on the edge of the breast beam 'for each .piece of webbing being woven, and with an additional number of warp beams in order to cause the warp threads that are woven into the webbing adjacentthe \convexed outer edge to feed fasterthan those that are woven into the webbing adjacent the concaved edge. In a webbing loom operating, say, twenty to thirty shuttles, the expense of installation of the additional warp beams, conical takeup rolls and special guidesgreatly increases the loom cost. as compared with the original cost of looms fitted to weave straight warp webbing. Furthermore, the stretching to which a large proportion of the warp threads must be subjected in order to be properly'woven into a curved fabric results in more frequent breakageof the threads and more frequent stoppage of the 100111 in order to tie in the broken warp ends than is the case when weaving straight fabric' with-equal feed of warp threads. Therefore the cost of producing fabric curved in the weaving process, it will be apparent, is much higher than the cost of producing straight ,fabric ofthe same dimensions, weave, weight and quality of yarn.

' In accordance with thisinvention I am able 'to produce strips of cloth, or cloth blanks on either webbing or broadcloth looms, by weaving them with straight warp andfilling so as to produce different areas with redetermined different shrinkage capacitles, and thereafter moisten said strips or-blanks uniformly thereby causing them to assume the desired shape by he differential shrinking of the difi'e'rentareas:

In the manufacture of collars, for example,

I may weave strips of cloth with straight warp and filling, having zones adapted to shrink longitudinally different percentages, cut the'panels of folding collars therefrom,

and thereafter impart the desired curvature to thepanels and fold line; and efi'ect the required off-setting of the outer panel by the usual washing, bleaching or dyeing op I 'is necessary additional to the usual finishing operations b which woven fabrics, bleached or dyed in t e piece, are subjected. But increased savings result from the facts (1) that the articles may be made from unbleached fabrics and the soiling received by them during manufacture may be removed in the one bleaching or other liquid treatment; (2) that less bleaching or other treating material is consumed because the cuttings and waste are discarded before liquid treating; that the article and its during manufacture because they are of straight woven cloth. 'llhese economies are additional to those secured by reason of the fact that the fabric used is woven straight The principal objects of the invention, therefore, are to make articles such as collars from straight edged webbing orstrips of cloth and thereafter impart to the articles a predetermined different form by differential shrinkage; and to make collars or the like from fabrics .inwhich the threads of the two systems or series of threads are "straight, and thereafter impart a curve to the collar in the direction of the threads of one system by unequal shrinking of different longitudinal areas thereof.

The invention consists of the method described hereinafter, exemplified ,in the drawings and defined in the appended claims.

In the accompanying drawing, which serves to illustrate diagrammatically the manufacture of one piece and two piece folding collars;

Fig. 1 represents a piece of unbleached webbing adapted for use in making onepiece folded collars;

Fig. 2 is a diagrammatic cross section of a f agment along the line 22 of Fig. 1;

ig. 3 re resents a collar cut from the straight unb eached fabric of Fig. 1.

Fig. 4 shows the collar of Fig. 3 after having been subjected to a washing or bleaching operation; and

Fig. 5 is a view Fig. 4, folded.

The diagrammatic cross sections of the drawings are merely exemplary of fabric structures that may be made use of in carrying out this invention. Difierent relative shrinkage capacity,that is, susceptibility of contracting, when moistened, different perof the collar shown in rare.

parts can be more easily manipulated i the warp is shown as of difierent structure in, diflerent parts of the same piece of fabric, whereby toprovide lmown and definitely controllable differences in relative capacity to shrink in the direction of the warp in different longitudinal areas, zones, or panels. The relative shrinkage capacities of the warp yarns may be varied progressively from one edge or division line to the other of one piece of fabric or they may be varied progressively in groups of warp threads, zones, or hands of a fabric orwebbing from which it is desired to manufacture one piece collars. The relative amount of shrinkage is susceptible of accurate control by careful construction of the Warp and the radius of curvature may be predetermined with accuracy. 1

It is not practicable to illustrate all of the expedients by which different relative shrinkage capacities may be-Vimparted to different longitudinal; areas or difi'erent strips of fabric. Susceptibility of contracting d1fferent percentages may be imparted to adj acent zones, by using fiber of different kinds forgthe warp threads of thedifferent zones or strips, or by variations in the warp structure, or by both. Warp structure may be varied in many ways in order to yield the desired results; the warp threads of one zone may be of a different count (size). than those ofanother; they may be composed of multiferent number of turns to the inch; or one zone may be provided with straight, uninterlaced Warp threads that are absent from another, or more numerous in one zone than in another or other differences of structure may be introduced along different areas to produce the desired effect. Similar variations in the filling threads may be utilized to produce cloth susceptible of assuming a precalculated non-rectangular outline; and combinations of both warp and filling, variedasdescribed, may be adopted for the purpose of producing cloth'articles of predetermined form, as will be apprehended by persons skilled in the textile arts. It is to be understood, therefore, that the invention is not dependent upon any particular means whereby one area, zone, or panel in a collar or like article is adapted to shrink a greater or less percentage than another.

ric, 5 the filling of the back ply, 6 the warpthreads in the face ply of the panel 12 and fold zone 18, 6 the warp threads of the back ply, 7 straight stuffing warp threads,

and 8 binder threads interweaving the face I, ply and back ply and clamping between them the straight stuffing warp threads 7.

In the panel 11, 16 indicates the warp threadsof the face ply and 16 the warp threads of the back ply. -.The panel 11 is devoid of stuffing warp, asshown. In order to compensate forthe absence of stufling warp, in case it is desired that the panel 11 be of the same weight to the square inch as panel 12, the warp threads 16, 16 may be made heavier or of lower count than the warp threads 6, 6 of the panel 12. For example: The panel 12 and the fold zone 13 may be woven of 60/2 yarn throughout while the panel 11 may have the warp threads in face and back ply of 10/2 yarn.

It will be perceived that, after moistening equally the panels 11 and 12 and fold zone 13, panel 11 will shrink a greater relative amount than panel 12 because of the absence of the stuffing warp from said panel 11. A collar may be out outof the webbing or other strip of fabric illustrated in Fig. 1, in its unbleached condition, the collar be suitably bound orotherwise finished and have the button holes formed therein. This collar, in an unbleached condition, will have straight panels 11 and 12 and a straight fold zone 13. After the collar has been completed of unbleached material, as illuster the collar assumes the form indicated in Fig. 4, with the panels 11*, 12? and foldzone 13" curved as indicated in said Fig. 4. This curvature has been imparted by reason of the greater shrinkage capacity of the neckband portion as compared with the outer panel or fold portion. As the shrinkage capacity of both panels has been carefully predetermined correct allowances can be made for amount of shrinkage in the manufacture of different sizes.

Although I have illustrated one way in which a one piece collar maybe made and have shown the outer panel portion of uniform structure throughout and the neckband portion of a different uniform structure but of greater relative shrinkin capacity than the outer panel, yet it will be understood that either or both of the panels or strips may be of variable warp structure from one edge to the other in order to impart a progressive shrinking capacity to suetraction.

cloth finishing and familiar with the properties of textile fibers that the principles of this invention may be applied in many other ways than those illustrated and specifically described.

As has been pointed out, the fabric is straight woven. In all weaving operations, the yarns are customarily and necessarily, under the present state of the weaving art, set in the looms under considerable tension, and this tension necessarily tends to stretch the yarns. IVhen the tension is removed, there is necessarily a counter-action of con- When the fabric is of substantially the same construction throughout, the shrinkage or contraction in the fabric after it has been taken from the loom is substantially the same throughout the fabric which therefore remains substantially. straight as it was woven. When, however, the fabric is made in accordance with the present inbeen takenfrom the loom is such as to impart a slightly curvilinear effect to the fabric. This curvilinear effect is not very pronounced in a short section of fabric but is readily discernible'in a long piece and is an advantage rather than a disadvantage inasmuch as the direction of subsequent curvature of the fabric is readily perceived.

The principle of this invention is obviously applicable to making articles of single ply fabric as well asof multiply interwoven fabric although, in the case of single ply. fabrics, stuffing threads cannot be used in the manner illustrated with reference to multiply fabrics. But it will be apparent that different relative shrinking capacities threads, threads of different twists or different counts or dilferent kinds of fiber or by combinations suitable for the purpose. By

this method,'one piece collars with curved fold zones and correspondingly curved warp yarns may be made from broad webs or from narrow webbing. Broad clothfor one piece collars may be woven on a fly shuttle j 100m, in a plurality of connected bands, orrelativel exempli e'd herein; the lines of demarkation between the bands or strips may be indinarrow strips, of the;char acter cated by any suitable expedient such as by inserting a colored warp thread between them or omitting one or several Warp threads. The broad fabric may then be cut into strips along the demarkation line and the strips thus severed made up into collars.

A collar or like article having adjacent elongated zones extending side by side longitudinally of one system of threads, said system of threads in one zone including straight stufing threads, corresponding threads being absent in another zone, the latter of which is shrunken a greater percentage than another.
