7 Claims.

This invention relates to a braid of a type commonly called cord edg braid by reason of there being a large rounded portion or cord at one edge with a fiat braid extending from that edge for attachment of the cord in position. The material is that used for decorative purposes on hats and the like.

The usual cord edge braid consists of a core or warp of a braided structure about which there is braided a covering with a flat braid extending more or less radially therefrom with the flat braid.

interlocked with the braid of the covering of the warp core. Such material is usually made on a braiding machine designed especially for this purpose and consisting of two braiding tracks which are interlocked in order that the braided yarns of the fiat fabric may attach to the braid over the cord.

One of the objects of this invention is to provide a cord edge braid on a machine known as a Vienna or oval braider but modifying the arrangement of thewarps of the usual Vienna or oval in such a manner that instead of providing a Vienna braid there will be provided a cord edge braid which will have a structure diiferent from the structure of the cord edge braid provided on the cord edge braider but suitable for'the same use.

Another object of the invention is to provide a cord edge braid at a lesser expense than that of the usual cord edge braid.

Another object of the invention is to provide a cord edge braid which may have a color arrangement in the form of a helical stripe rather than an intermingled color arrangement such as would be provided in the usual cord edge braid machine.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a plan view of one side of my novel construction;

Fig. 2 is a view similar to Fig. 1 showing the opposite side of the braid;

Fig. 3 is a plan view in diagrammatic form showing the paths of the carriers of the Vienna or oval braid machine, and illustrating the position of the cores which I insert in the machine for accomplishing my purpose;

Fig. 4 is a diagrammatic view greatly expanded, illustrating the path of the yarn which goes to form my cord edge braid;

Fig. 5 is a skeleton View of the yarns shown more clearly in their interlocking arrangement and patterned somewhat after the showing in Fi 4.

This invention modifies the usual braid formed on a Vienna or oval braider by Changing the D sition of the warps used in a Vienna braider and also the size of th warps which are used, the arrangement being such that a cord edge braid .is formed. In the Vienna braider there are two sets of carriers, each with the carriers in its set following its own path of travel. These paths interlock; and in carrying out this invention as shown in Fig. 3, I position a larg core within the path of one of these sets of braiders only, and eliminate the usual small core or warp positioned in the end loop of this path; and I position warps of smaller size Within the path of the other set of braiders only, whereby my novel result is formed.

With reference more particularly to the drawing, I have shown in Fig. 3 at H] diagrammatically the path of one set of carriers of the Vienna braider and at H the path of travel of the other set of carriers of the Vienna braider. It will be noted that the path ll] provides a loop doubled.

back upon itself as at I2, and the path H provides a loop doubled back upon itself as at [3. Likewise, the path of travel, l0 and I I, overlap one another. Usually at the'center location M in the usual Vienna braider there is provided a core. Likewise, in the usual Vienna braider at points l5 and I6 within the loops l2 and I3 there are provided cores.

In the construction which I provide, the core or warp at the center location I4 is entirely eliminated, and instead there is provided cores or warps at l6 and 11, both outside of the path ill but within the path II. The warps or cores l6 and I! are -of relatively small diameter and are the cores which are positioned in the fiat braid portion 20 of my cord edge braid. These cores serve to widen out the fiat braid desirable for attachment purposes and hold the flat braid in position as the braid is formed.

In order that the cord may be formed, I locate a'large core l8 within the path I0 of one Set of carriers but outsideof the path ll of the other set'of carriers, I have found by locating this large core in the position shown at 18, as distinguished from within the loop l2, no alterations whatsoever are necessary on the machine. However,

it is possible that I may locate the core I8 at the point l5 by some modification of the machine such for instance as rearranging the angularity of the lead from the carrier to the maypole of the braider.

In the structure which I provide, the core l8 consists of a plurality of warp yarns 2| such for instance as sixteen ends of 8/3 ply carded natural cotton yarn about which there has been braided as at- 22 a covering such, for instance, as two ends of a 300 denier colored rayon yarn. This may be covered on a sixteen carrier machine. These specifications, however, may be varied as will be readily apparent. The cores [6 dyed yarn and maybe of any color desired but preferably of a similar color to that covering the core [8. The carriers which would be used to travel the path In wouldbe equal tothe number of carriers which would'travel thepath l I;

and for the structure of yarn which I have above illustrated, I would use nine carriers in each set. The carriers which carry the yarn 23 will each wrap the yarn helically, as shown at 23, about the core is, as shown in Fig. 3; While the carriers which travel the path I I will carry, for the sake of the illustration which carries through this specification, although it clearly may be modified, /2 ply KP mercerized white yarn. They will wrap a layer of yarn as at 24 about the warp or core 16 and will braid an intermediate section as at 25 between this wrapping and the wrapping 23, as illustrated in Fig. 1, which will embrace the core or warp I1.

In the arrangement which I have illustrated,

and as seen in Fig. 3, there will be an interlocking of the colored yarns 23 and the white yarns 24, 25, some of the color being apparent at the crossings in the shaded position shown at 26, and

'there' being formed a rib of interlocked yarns at 21 which roll over close to the junction of the flat braid, designated generally 20, and the cord edge of the braid designated 28.

From the showing in Fig. 4, it will be apparent that one of the colored yarns, as 23, here designated 23', will emerge from the'fiat braid, extend about the core [8 returning as shown at the dotted line, also designated 23, and then interlock with the yarns from "the path Ill, as at 30,

and 3|, by extending beneath two of these yarns and then as at 32 and 33 by extending over two of these yarns, and then entering the fabric formed by the carriers in path I I- as at 34,- after which it again emerges in afurther repeat.

Each of the colored yarns follows this cycle of l repeats in its path in the fabric, it being apparent that, there being nine carriers, the repeat will exist every nine helical wraps of theyarn about the cord core I8. It will be readily ape.

parent that, if I employ different colors of the yarn on the carriers in the path I0, each of the colors will show up as a helical wrap in the yarn 23 about the cord which forms the edge of the fabric. successive carriers of one .color and six carriers of another color, whereby there would be a helicalstripe formed one-third the col-or of the three carriers and two-thirds the color of the six carriers.
