ELASTIC WEBBING.
Specification of Letters Patent.
Patented Dec. 16, 1913.
Application filed April 15, 1912. Serial No. 691,066.
To all whom it may concern Be it known that I, WALDEMAR KoPs, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented a new and useful Improvement in Elastic Webbing, of which the following is a specification.
Heretofore elastic webbing has been made in various widths and lengths, and usually in long strips that may be severed into pieces of any desired length, and great trouble has been experienced in securing ends of elastic webbing to garments on account of sewing threads cutting the elastic strands, and the same thereafter pulling appreciably through the webbing and thus losing utility.
Elastic webbing has also been made in various widths and in lengths in alternating sections of elastic and in-elastic integral parts, adapted to be severed in either or both the elastic and in-elastic parts. It has heretofore been usual in weaving the in-elastic parts of such webbing to release the tension upon the elastic strands or elastic warps and weave the in-elastic parts under normal conditions without tension.
In the elastic webbing of my invention, and the method of making the same, the warp threads are maintained taut, and the interspersed elastic strands or elastic warps are placed under the desired tension. The elastic parts of the webbing are formed of these warp threads and loose or spaced weft threads, and the alternate in-elastic parts, or sewing sections, are formed of these warp threads and close weft threads and the weft threads are constant and equal in size.
I have found by experiments that in certain elastic webbings, especially when they are not of a heavy character, or in other words, have not a great amount of cotton stock, that the elastic threads are not held with suflicient grip in the non-elastic or sewing section, and interlacing of threads more frequently in said section does not always improve this condition, that it is necessary in such cases to add additional warp threads and thereby entirely overcome any possibility of the rubber strands pulling down through the webbing.
I have found by experiments that the elastic warps are not held with sufficient grip in the nonelastic or sewing sections by the employment of the usual number of warp threads, and that this condition is not always overcome by packing the weft or fillmg threads as tight as possible, but that this condition is entirely remedied by employing a greater number of warp threads than usual.
I have discovered that additional warp threads drawn in the loom in such a manner that they weave with the rubber strands as dead warps in the elastic sections without being interlaced with the filling threads and thereby not interfering with the elasticity of the webbing but in the non-elastic sections being interwoven with the filling threads, produce a tighter weave and a non-elastic section. In this manner the weaving is clifferent in the sections, all of which is hereinafter more particularly set forth.
In the drawing, Figure 1 is a plan view representing a strip of webbing according to my invention. Fig. 2 is an approximate longitudinal section of exaggerated size for clearness. Fig. 3 is a partial cross section at the dotted line 00 w of Fig. 1, through the elastic section, also of exaggerated size, and a size corresponding approximately with Fig. 2 for clearness. Fig. 4 is an approximate cross section at the dotted line l y through the sewing section, showing an arrangement of the weft threads. Fig. 5 is a plan view illustrating the manner of weaving the elastic section of my invention. Fig. 6 is a plan View of the manner of weaving the sewing or inelastic section of my invention, and Fig. 7 is a plan View of a modified form of the weaving of the elastic section of my invention.
All the figures of the drawing are diagrammatic.
Referring particularly to Fig. 1, a, a represent the elastic sections, and Z; the nonelastic or sewing section, and referring to the other figures, 0 represents the numerous elastic strands or warps, (Z the warp threads and c the weft threads. Fig. 2 particularly represents, by this longitudinal section, the fabric as in the act of being woven, with the warp threads taut and the elastic warps or strands under tension.
The elastic webbing of my invention may be of any desired width and thickness and of any desired length, the sections a, a and Z following one another as a continuous strip. The elastic sections are of any desired length, and the non-elastic or sewing sections also of any desired length, there being a non-elastic or sewing section between two elastic sections. I
In the weaving of the elastic sections of my invention, the weft threads in parts a, a are laid an appreciable distance apart, so that when the tension under which the elastic web is woven is released, the rubber strands and warps contract and the weft threads e assume a close relation to one another, and the warp threads d are more or less puckered until tension is again applied to the webbing. These weft threads are constant in size throughout the webbing.
In the weaving of the non-elastic or sewing section b, the weft threads are not spaced, but are woven as closely as practical.
Figs. 3 and 5, which diagrammatically show the weaving in the elastic portion of the webbing, are intended to show the weft or filling e, the rubber strand 0, the warp threads (1, and additional or dead warp threads (l at either side of the elastic warps c. It will be noted from these figures that the additional or dead warps (Z weave with the rubber strands 0 and are not interlaced with the warp or filling 6, while in Fig. 6, which diagrammatically shows the weaving in the non-elastic section, not alone are the I weft threads 6 very closely spaced, but the character of the weave is a closer one, and the additional or dead warp threads (Z are 3 interlaced as frequently as possible with the filling and as frequently asthe other warp threads. Hence the weaving is different in the elastic and inelastic sections.
I found by experiments that where the usual number of cotton warp threads are employed, that a close packing of the weft threads will not alone hold the elastic strands or warps so that there is no possibility of their slipping under tension, and in order to make this form of elastic webbing commercially successful and fully capable of performing the function, in use required thereof, I have added additional or dead warp threads between each of the elastic strands or warps and at either side thereof, and in doing so have preferably slightly thickened the webbing, burying the elastic warps or strands deeper than usual in a mass of threads capable of binding and being bound tightly around the elastic warps. I have also found by experiments that while it is necessary in weaving webbings that have little cotton stock, known as loom or lisle webs in the trade, to use not alone additional or dead warp threads and closely space the weft threads in order to make thefnon-elastic section, but I have found that with increasing the weight of the webbing, webs which are known in the trade as twill webs and the like, it is only necessary to add additional warp threads and interlace them with the weft or filling thread, and that the filling thread need not be more closely spaced in the non-elastic than in the elastic section.
In Figs. 4 and 6, it will be noticed that the weft threads pass over and under each elastic strand and each and all the intermediate cotton or other warps, holding the same firmly and tightly, whereas in Figs. 3 and 5, the cotton or other weft threads pass over and under each elastic warp and each adjacent and additional cotton or other dead warp, while the intermediate warps are in series of two each, over and under which series of two, the weft threads are arranged. I do not limit my invention, however, to exactly the methods of laying the weft threads hereinbefore described and shown in the drawing.
The addition of the extra warp threads further makes a very substantial sewing section for the whole of the threads by which the elastic webbing at its in-elastic section is secured to a garment with less liability of the sewing threads cutting any of the elastic strands.
I claim as my invention:
1. An elastic fabric comprising warp and weft threads and elastic strands, woven to have an elastic section and an inelastic section' and in which in the inelastic section the wefts and warps are all closely inter laced and in the elastic section are interlaced only in groups.
2. An elastic fabric woven throughout with the elastic strands at substantially the same tension and in which there are elastic sections and alternate inelastic or sewing sections and in which in the inelastic or sewing sections the weft thread is closely interlaced with all the cotton and elastic warps and in the elastic section is interlaced only with groups of the cotton and elastic warps so that the threads lie close together in the inelastic or sewing sections and are spaced apart in the elastic sections.
Signed by me this 11th day of April,
WALDElMlAR KOPS. Witnesses:
