1W Ww United States Patent O HEADING TAPE FOR DRAW 'CURTAINS John Raymond Lilley, Allestree, England, assgnor to Narrow Fabrics (Lilleys) Limited Application October 5, 1955, Serial No. 538,652

Claims priority, application Great Britain November 12, 1954 6 Claims. (Cl. 139-390) This invention is for improvements in heading tape for draw curtains of the type formed with spaced loops for receiving curtain hooks and which is sewn to curtains along the top margin thereof so that the tape forms a connecting medium between the curtains and the hooks, the latter riding on guides for ease in drawing of the curtains. Usually the tape is provided with draw strings which extend in and out of the tape and by which the curtains may be held in pleated formation.

I'he loops of the tape have been formed either integral with the body of the tape or initially separate from and subsequently attached to the body of the tape, and they have been formed in different shapes to suit diiferent shapes of curtain hooks and other purposes.

In all such constructions the loops have been formed of woven fabric i.e. composed of warp threads and weft threads such as to form with the body of the tape a double wall of woven fabric, and in order to produce this it has been necessary to employ a two-shuttle loom. It will be understood that the cost of production of the tape is to some extent governed by the type of loom employed and in the consumption of thread thereby.

An object of the invention is to provide a construction of heading tape which although having the saine utility as tape of the type referred to may be produced with such less thread consumption and on such a diierent loom as to be cheaper to produce.

The invention provides heading tape for curtains comprising a woven body part having at least one thread parallel to the warp threads of the weave which oats at dilerent locations in the tape to form loops on the tape for the reception of curtain hooks. Said thread may float at said locations on either face of the tape. It may be woven in the tape between said locations. Alternatively said thread may extend through the tape without weaving in the tape between said locations. Said thread may float over woven parts of the tape.

Conveniently there is a central group of threads parallel to the warp threads of the weave and floating at the different locations in the tape to form loops on the tape for the reception of curtain hooks. The threads of this central group are conveniently constituted by spaced warp threads interspersed with other warp threads of the weave. Said thread or each of said threads is preferably a thick thread or cord. These warp threads which are interspersed with said threads are preferably thinner then the remaining warp threads.

Draw strings may be provided extending over either face of the tape at said locations.

At least said loops may be distinctive in colour from the remainder of the tape by said thread or each of said threads being of acetate yarn, or by being of a dilerent colour to the remainder before the tape is formed.

The above and other features of the invention set out in the appended claims are incorporated in the constructions which will now be described as specic embodiments of the invention with reference to the accompanying drawings in which:

2,888,958 Patented June 2, 1959 Figure 1 is a perspective view of heading tape according to the invention.

Figure 2 is a somewhat diagrammatic view showing the construction of the tape.

Figure 3 is a diagrammatic longitudinal section of Figure 2. t

Figure 4 is a perspective view of a modiiied form of the heading tape, and

Figure 5 is a further modified form of the heading tape.

Referring now to Figures 1 to 3, heading tape for draw curtains is provided comprising a woven body part 1 composed of weft threads 2 and warp threads 3 interwoven to suitable width. In the illustrated example the weave is 1 x 1; in an alternative by way of further example, but not shown, the weave may be that known as 2 x 2 twill.

For the purpose of attaching cutain hooks to the tape the tape has loops at different locations along it for receiving the hooks. In the illustrated constructions `these loops are formed by a group of warp threads of the weave in a manner to be fully described but it is to be understood that the loops may be formed by only one thread or two or more adjacent or spaced threads of the weave (or otherwise parallel to the warp threads of the weave) in similar manner to that in which the loops are formed by said group of warp threads of the weave.

Referring now to the illustrated constructions, a central group of warp threads 3a of the warp threads 3 of the weave oat at dierent locations in the tape to form loops 4 for receiving the curtain hooks. The formation of the loops 4 is illustrated in Figure 3. More specilically the warp threads 3a extend into and out of the tape at opposite sides of said different locations and at these locations they float across woven body parts of the tape to form the loops 4.

The warp threads 3a are interspersed with warp threads 3b of the weave. There are eight warp threads 3a interspersed with seven pairs of warp threads 3b.

The warp threads 3a are thick threads or cords which are thicker than the remaining threads in the tape. Alter-` natively the warp threads 3a may be of synthetic yarn such as acetate or Courlene (in which instance the warp threads 3a may be fused together during iinishing of the tape), or knitted tubes each with or without a core or covered wire.

The warp threads 3b are thinner than the remaining threads in the tape by being of 2/285 fine cotton.

The diierent thicknesses of the warp threads 3a and 3b is such that at said locations the warp threads 3a are in contact each with the next i.e. without visible gaps between them, thereby completely covering the weft and warp threads of the body part of the tape atsaid locations. (Figure 2 shows gaps between threads for clearness of illustration only.)

The warp threads 3c at the sides of the tape are composed of twenty-tive warp threads at each side of 2/16El American cotton.

The weft vthreads 2 may be of 2/2s American cotton.

In the constructions of Figures 1 to 3 and 5 the Warp threads 3a float alternately on opposite faces of the tape to form their loops 4 alternately on opposite sides of the tape.

In the construction of Figure 4 the warp threads 3a float on one face of the tape only to form their loops 4 only on said face.

The warp threads 3a, in the constructions of Figures l to 4, are woven in the tape between said locations.

In the construction of Figure 5 the warp threads 3a extend through the tape without weaving in the tape between said locations.

Draw strings are provided, in the constructions of Fig assassin E tires 1 to 4, of 12/15s American 'cable cord. More speciiically in 4the constructions of Figures 1 to 3 a pair of draw strings 5 extend longitudinally of the tape and through the tape in such opposite facial directions alternately at successive positions between said locations that where parts thereof register with the loops 4- such parts extend on the opposite face of the tape to that of the loops 4 with which they register. ln the construction of Figure 4 the pair of draw strings 5 extend through the tape in such opposite directions at each of said positions that where parts thereof register with the loops 4 such "parts extend on the same face of the `tape as that of the loopsoel with which they register; furthermore at said locations said parts of the draw strings 5 extend along the top and the bottom edges of the loops 4. At least said loops 4 may be distinctive in colour from the remainder of the tape by the warp threads 3a being vrof' acetate yarn whereby the distinctive eiect is obtained upon subsequent dyeing of the tape. Alternatively the warp threads 3a may be of different colour' from that of the remaining threads before the tape is formed. i The tape may' be produced as a single shuttle loom is being only necessary to set up warp threads in appropriate manner and vto repeatedly hold the warp threads 3a (and the draw strings when provided) in an idle position spaced from either face of the body of the tape, as required, during appropriate picks.
