ATTORNEYJ Patented Aug. 21, 1934 PROCESS OF WEB MATERIAL MANUFACTURING WOVEN AND THE PRODUCT RESULTING THEREFROM Ray W. Springer, Detroit, Mich. Application July 22, 1932, Serial No. 623,917

4 Claims.

My invention relates to an improved process of manufacturing woven fabric or otherwise fabricated web material and the resulting improved products.

One object is to provide an imploved process for producing woven fabric webs of varying widths rapidly, economically, and in such a manner that the webs are readily adaptable for any desired use.

.One object is to provide an improved process ass of the character described which includes the fabricating in a wide width of a plurality of individual webs of desired widths, providing lines of intended severance separating the several web widths, treating the material along the lines of intended severance to prevent unravelling of the individual webs following severance, severing the material along the intended lines of severance to form the web widths. My process also includes the employment of such webs as hereinafter set forth. One use to which my improved web may be put is to apply the web widths to a suitable welt body or other body structure as a covering therefor, all as a continuous process 01' manufacture which may be accomplished cheaply, economically, and expeditiously.

A further object is to provide an improved resulting product of this improved process which comprises a wide web of fabric having weakened lines for severance of the material into separate web widths, which fabric material has lines of adhesive substance extending along the weak ened line portions between the individual webs and securing the threads-of the fabric together along such weakened lines whereby, upon severance of the material into the determined pluralityof web widths, unravelling of the material will not result.

A further object is to provide web widths of varying sizes having adhesive coated edge portions securing the same against unravelling and adaptable upon application of the woven web as a covering to a welt body to secure the covertfi ing in place about the welt body.

My invention includes as a meritorious feature the provision of the woven web of material with the'weakened lines of severance and the provision of such material with adhesive substance extending along the weakened lines of severance and the provision of the individual web widths with edges secured against unravelling at the line of adhesive substance and the provision of an ultimate Iproduct which includes as its covering one of the individual web widths adhesively secured thereto by the adhesive substance which prevents unravelling at its edge.

Other objects and meritorious advantages of my invention will more fully appear from the following specification, appended claims and accompanying drawing, wherein:

Fig. 7 is a prospective of a fragment of a modified form of a resulting product of my improved process.

In the carrying out of my invention I weave or otherwise form in a single piece a multiplicity of fabric web portions. These may be of varying widths. In a preferred method the portions which are to constitute these separate webs are separated from each other by the omission of one or more warp ends. Other alternative lines of demarcation may be employed to indicate the proposed lines of severance. This preferred construction is shown clearly in Fig. 1. In Fig. 1 individual web portions are illustrated. One of these web portions is indicated by the numeral 10. This web portion has a face portion and two selvage portions at its side margins. The other web portions would be similarly woven. By the term web I intend to include any narrow woven material, or felted material, which may be employed as a covering material or for any other purpose such as hat bands, ribbons, gimps, or any other use.

The weft extends through the several webs. The webs are separated by weakened lines produced by the omission of one or more warp ends. One of these weakened lines is indicated by the numeral 12. This method of weaving is well understood and does not need further description. Following the weaving of fabric after this fashion it is passed from the roll 14 illustrated diagrammatically in Fig. 4 over other rolls 16 and 18 and brought into contact with an adhesive application roll 20 which receives adhesive from a roll 22 that revolves in a vat of adhesive 24 so that web sections to adhesively secure the adjacent warp ends of the web sections to the weft of the woven fabric.

It is understood that the fabric may be woven in any desired width and any desired number of web sections may be provided and that these web sections may be of varying widths or weave as is found desirable and that the entire width of fabric may be withdrawn from roll 14 and passed into contact with a multiplicity of rolls 20 to ap-' ply adhesive to the various weakened lines 12. The fabric is then taken through suitable treating mechanism. This may be of any conventional form. In the diagrammatic illustration in Fig. 4 the fabric is shown as passing over a hollow heated drum 26 and over a series of rolls 28, 30, and 32 to be brought into contact with a cutting knife 34. Obviously a series of cutting knives 34 would be provided to sever the fabric along the adhesive covered weakened lines 12. The arrangement of the adhesive application rolls 20 and the cutting knives 34 would, of course, be such as to produce the desired result.

The process is so carried out that the adhesive which has been applied to the weakened lines 12 will be allowed to set sufficiently to secure the fibers of the material together against separation so that upon the severance of the fabric material along the indicated lines of severance the threads of the material will be adhesively secured together against possibility of unravelling. By the term adhesive I intend to imply the employment of any suitable substance which would bind the fibers of the material together.

Through the employment of this process it is possible to weave on a single loom a multiplicity of webs of material of varying widths so as to apply adhesive thereto as indicated and to sever the material as described to produce a multiplicity of woven webs of desired varying widths.

The separate webs which are produced after the severance of the material each has its out edge shielded by the adhesive which has been applied along the weakened line of severance and is therefore held against unravelling. Such webs may be employed in various ways, one use to which they may be put is to employ the web as a covering for a core of one form or another to produce a welt or a trim piece used in upholstery work. One particular use is to produce welts and trim articles which are used in automobile body work. In Fig. 6 I show such a trim product. There is a cylindrical or tubular core member 38 which has been covered by one of the webs. This is a web wherein the adhesive has extended a substantial distance over the web so as to seal the two marginal portions which form the flange that extends outwardly from the tubular core together and about the core. In Fig. 7 there is illustrated a form of the web wherein the adhesive coated marginal portions have been folded over to provide folded edge portions 40.

In Fig. 5 there is illustrated diagrammatically a further step in the process. In this step the web is taken after it has been formed carrying the adhesive on its edges and is wound on a roll. The

roll is indicated as 42. The web is unwound from this roll and passes through a folding machine indicated generally at 44 and tubing comes down from the roll 46 and the web is folded about the tubing and the adhesive coated portions are adhered together.

It will appear that this step so follows the other steps in the process that the adhesive which has been applied to seal the edges is employed to secure the strip about the core member so that only one application of adhesive is necessary to produce the complete welt or finished product. It is, of course, apparent that the web'strips as formed individually are suitable products for commerce to be applied by stitching or adhesive wherever the customer may desire. It is also apparent that the web might be formed as shown in Fig. 7 to produce an even rather than a cut edge.

It is of courseobvious that the specific apparatus herein illustrated represents merely one preferred form which is capable of use and that any other suitable apparatus may be employed to carry out the process described and that the invention is limited only within the scope of the appended claims.
