SLIDE FASTENER STRINGER Filed March 23 1961 Ticl. E.
PlCK K PICK 2 P\CK 3 PICK 4- INVEN TOR. 7 6 (/2445: A. fif/voza United States Patent 3,143,779 SLIDE FASTENER STRINGER James A. Hendiey, Staniey, N.C., assignor to Talon, Inc., a corporation of Pennsylvania Filed Mar. 23, 1961, Ser. No. 97,856 Claims. (Cl. 242t}5.16)
This invention relates to slide fasteners, and more particularly to the type wherein the interlocking means consists of a continuous pre-formed filament such as a coiled or spirally-arranged filament. In the present invention the filament is secured to the edge of the tape during the weaving thereof.
While it has been suggested broadly to weave the preformed filament into the edge of the tape at the time of weaving thereof, in most cases an unsatisfactory product was obtained, primarily, for the reason that the filament was not properly secured to the edge of the tape. Usually the filament was too loosely interwoven with the weft threads which resulted in a stringer in which the filament was not satisfactorily afiixed to the edge of the tape and distortion or displacement of the filament often occurred when in use. It is imperative in such a woven-in-filament construction that the filament be subjected to the proper tension, both during the weaving operation and in the resulting product, so that the filament is firmly held and, yet not distorted, and it is to an improved stringer having these advantages that the present invention relates.
Accordingly, it is the general object of the present invention to provide an improved stringer for slide fasteners in which a pre-formed filament is woven integral with the edge of the tape at the time of the weaving thereof which is inexpensive in its construction and, at the same time, strong and rugged whereby a satisfactory slide fastener stringer is provided.
It is another object of the invention to provide such a stringer having a new and improved weave for securely attaching the filament to the edge of the tape so as to prevent any displacement or distortion thereof both during the weaving operation and when it is in use.
It is a more specific object of this invention to provide an improved Woven-in-filament type stringer for slide fasteners wherein there is provided an elongated relatively large cord to which the series of convolutions of a preformed coiled filament are securely bound by means of a plurality of warp threads arranged therearound which are interwoven with a weft thread so as to securely affix the filament to the cord and, at the same time, to provide a headed edge construction along the edge of the tape directly next to the filament.
Various other objects and advantages of this invention will be more apparent in the course of the following specification, and will be particularly pointed out in the appended claims.
In the accompanying drawings, there is shown for the purpose of illustration, an embodiment which my invention may assume in practice.

3,143,779 Patented Aug. 11, 1964 FIG. 7 is an enlarged edge view of the stringer shown in FIG. 2, and
FIG. 8 is a weavers diagram for the improved tape stringer of my invention.
The present invention will be described with reference to the interweaving of a continuous coiled filament consisting of a series of interconnected convolutions of the type shown in US. patent to Nicholas Wahl, No. 2,300,442 dated November 3, 1942. Such filament is made preferably of nylon, perlon of of some other suitable plastic material. While the present invention is illustrated in connection with a coiled filament, it will be understood that any other type of continuous pre-formed filament may be employed, such as the so-called Ladder or Meander type.
In FIG. 1 of the drawings, there is illustrated a slide fastener having a pair of stringers T incorporated therewith constructed in accordance with present invention. Each of these stringers consist of a web portion W and a beaded edge B having a continuous coiled interlocking filament F attached to the outer side thereof and on which there is arranged a slider S for longitudinal movement therealong for interengaging and disengaging the opposed coiled filaments F in a manner well known to those skilled in the art.
According to the present invention, and referring more particularly to FIGS. 2 through 7 of the drawings, the outer beaded edge B of each of the stringers consists of a longitudinally extending stuffer cord C having a plurality of longitudinally extending warp threads arranged therearound in substantially circular fashion so as to be substantially concentric therewith, eight in the present instance, and designated as 2 through 9 of the drawings. The body of the tape is of a conventional twill design or weave and consists of a plurality of warp threads 10 interwoven with a weft or filler thread 12. The weave of each of the picks as shown, is generally over one and under one of the Warp threads throughout the tape, but any other suitable weave may be provided.
The tape stringer in accordance with the present invention is well adapted to be woven on a needle or shuttleless loom. As clearly illustrated in FIGS. 2 through 6 of the drawings, the first pick of the weft 12 which is a double pick passes through and between the warp threads 10 in the web so as to be interwoven therewith, then in under the warp thread 9 at the beaded edge on one or upper side thereof, as shown in FIG. 3, over the warp threads 6, 7 and 8 at said edge, and over and around a convolution of the coiled filament.
The second double pick passes through the web, then over warp threads 2 and 3 of the beaded edge on the opposite or lower side thereof, as shown in FIG. 4, in under the warp thread 5 of said edge, and again over and around a convolution of the filament F.
The third double pick of the weft thread passes through the web, then over the warp threads 8 and 9 of the beaded edge on the first or upper side thereof, as shown in FIG. 5, in under warp thread 7 and over warp thread 6 of said edge, and, as before, over and around a convolution of coiled filament F.
The fourth and last double pick to complete one weaving cycle passes through the web, then over the warp thread 2 and in under the warp thread 3 of the beaded edge on the second or lower side thereof, as shown in FIG. 6, over the warp threads 4 and 5 of said edge, and again over and around a convolution of the coiled filament F.
In FIG. 8, of the drawings, there is shown a conventional weavers diagram for the particular tape stringer herein illustrated. The diagram refers to the position of the harnesses and frames, the crossed white squares and black squares corresponding to an up position and the all white squares corresponding to a down position, or vice versa. The right hand side of this diagram represents the weave of the beaded edge. The black squares correspond to the warp threads 2 through 9 together with the stufier cord C which form the beaded edge and the filament F. The remainder of the diagram is a harness diagram with the crossed white squares corresponding to the warp threads of the web W.
As a result of my invention, it will be seen that there is provided a stringer for slide fasteners of a woven-infilament type construction in which the filament is held firmly and securely in position due to the arrangement and interweaving of the weft thread with the warps and cord at the edge of the tape together with the convolutions of the filament. It will be noted that the elongated filament F is held securely in position directly next to the elongated cord C by the weft thread 12 so as to provide a rather compact arrangement.
It will be seen further that an elongated beaded portion is formed along the edge of the tape directly next to the coiled filament due. to the arrangement of the cord C and thewarpthreads arranged therearound which are interwoven with the weft thread 12 which is a most desirable feature in this type of stringer construction and one of the most important aspects of the present invention.
While I have shown and described an embodiment which my invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised within the scope of my invention as defined in the appended claims.
