COMPLETE SPECIFICATION.
Curtain Straps with Loops or Binding Cords for Attaching the
Curtain to Rings and Poles.
I, ADOLF VORWERK of Barmen 7-9 Kohlgartenstrasse, Germany, Manu-
facturer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:--
This invention relates to curtain straps with loops or binding cords by means of
which the straps, which previously have been sewn or otherwise connected to the
upper edge of a curtain, can be fixed to the curtain or pole rings, either by
slinging the loops on or into the rings as will be shown hereafter or by binding the
two open ends, formed by cutting open a previously made loop, to the ring.
In the annexed drawing
Figs. 1 & 1B show a single curtain strap with the thread forming the loop or
the binding threads laid into the web from distance to distance like a weft thread.
Figs. 24 & 2B show a single curtain strap in which the loop or binding thread or
cord is imbedded in the fabric in hose like manner that is to say by forming a
hollow part which surrounds the binding cord where it does not form a loop at one
edge of the same;
Figs. 3 & 3 are representations of a double curtain strap with the loop or
binding cord connected to the web in the middle of its width or at the folding
edge;
Fig. 4 is a figure indicating the manner of making the straps according to
Figs. 2 to 3 ;
Fig. 5 explains the manner of slinging the loop on to a curtain ring;
Fig. 6 shows the use when the loop is cut open to form free binding ends.
The main and characteristic feature in all manners of carrying out my invention
is that the loops are long enough so that they can be slung upon or into a curtain
ring as indicated by Figure 5 or on a pole and that, when made with open binding
ends, these can be tied to the ring as indicated in Figure 6. The loops or binding
ends must be of such distance from each other, that the curtains when pulled
together form large folds and therefore can be gathered into a small space. Thus
Figure 1 represents a curtain strap in which the cord or thread forming the loop is
woven into the band right across-like ordinary weft threads C, A D the weft
forming the loop B is pulled out so much beyond the edge of the band as to form a
loop of sufficient length as shown. This can be easily done by the weaver by
laying the thread for instance round a rod or by holding the thread for the time by
a hook and freeing it after a few further shoots have been done. This is nothing
new in itself. The loop thread having thus been secured by the wefts C, A, D the
weaving is carried on with the loop thread E lying free along the edge where no
loop is to be made, when again wefts C, A, D are laid in as before.
Now it is clear, that the thread E lying free along the edge of the strap is
practically cf no use and it may therefore just as well be cut off as indicated by
Figure 1B.
The curtain strap shown by Figures 24 & 2B differs from the preceding ones in
that, that the thread or the cord F for making the loops G is here connected to the
web in form of a warp thread which is surrounded by weaving or braiding in a
boselike manner that is by forming at the respective edge a hollow part like a hose
as will be bereafter explained more fully. According to the example shown by
7
f

page_text: Figure 3 and 3 the loop or binding thread or cord H is connected to the woven
strap T in a similar way as in the examples of Figures 24 & 2B with the difference
however, that the loop thread is laid in the middle of the width of the strap, the
loop thread projecting at certain distances from one side of the fabric, this thread
itself lying open at the other side or being bound by weft threads, or it may also
be fixed by sewing and then the strap is folded double along the middle line.
In the example shown by Figure 3B a double band or strap is produced and at
one side both parts are so connected together that they form at this side a hose,
surrounding the loop thread where it does not form a loop; the loops or open
binding ends being formed in similar manner as before.
Now as to the manner how these curtain straps according to Figures 2-3B are
made, the mode of working is based on the idea of producing a certain length of
web woven or braided, with the cord, thread or ribbon serving for making the
fixing loop or fixing cords interwoven or interlaced with the web so that a hose or
tube like part is formed at the edge of the strap, surrounding said cord, then
pulling off a sufficient length of that cord from the reel, so that the loop will be
formed, or the two ends for tying the curtain ring to the strap by cutting the
loop open then proceeding with the weaving or braiding operation in the same
manner with said cord interwoven or interlaced in hoselike manner as before until
a new loop or binding ends have to be made.
Figure 4 of the accompanying drawing indicates the manner of proceeding. Let
us suppose that the strap with the loop Lou it has been made, the workman then
proceeds with his work and makes in the ordinary way the length of strap from a
to with the cord or thread L' provided for the purpose, as a warp thread when
the strap is woven and as a "central thread" when the strap is being braided.
At the point 6 the thread L¹ is seized by a hook H', by means of which a sufficient
length for making a loop or binding ends is pulled forwards in the direction of the
finished fabric and then the weaving or braiding is proceeded with until a further
loop is to be made. The loop being bound directly at its root where it stands out
from the edge of the strap. In proceeding with the work the loop frees itself from
the hook, so that it will be ready for a following seizure of the loop thread. The
book may be worked by hand or mechanically and it may be fixed to the loom or
the braiding machine in any suitable manner.
The gist of the invention in all cases consists in this: Making a certain length
of strap with a special thread or cord for forming the loop at one side, which
thread is interwoven or interlaced with the strap by forming a hollow part
surrounding said cord where it does not form a loop, pulling out at certain intervals
so much of said thread as will be required for making the loop and binding the
loop immediately at its root, where it comes out of the edge of the strap by
proceeding with weaving or braiding as before.
.
When the thread forming the loop is cut equally in two, the two new open ends
serve for binding the ring to the curtain, whereas the loop is slung into it as is
indicated in Figures 5 & 6 respectively; the ends of the open cords may be
furnished with some decorative device as shown.
When the loop is to come out from the middle of the strap or from the folding
edge as is indicated by Figure 4 then the strap is woven or braided in the same
manner with the loop thread lying in the middle as warp or as central thread and
it is seized by the hook and pulled out in the same manner as described before, or
two straps may be woven one above the other in the well known manner and both
bound together at one side, forming a hose in which the loop-thread is contained.
These are in themselves operations well known in the weaving and braiding; the
novelty of my invention consists only in the manner how the loop is made.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, I declare that what ]
claim is:
1. Curtain straps with loops or binding cords for attaching the curtain rings a

page_text: a new article of manufacture consisting of a single or double woven or braided
strip (band or lace) from one edge of which, (or from the folding edge in the case
of the double straps) extend long loops or open ends for attaching the same to the
curtain ring (Figures 5 & 6) the whole as illustrated and specified and for the
purpose set forth.
2. Making curtain straps as specified in Claim one by using a special thread or
cord which is being laid into the web either as weft thread at certain distances and
interweaving it with the web and pulling it out from the edge to form a long loop,
or interweaving it with the web by forming a hollow part which surrounds the said
cord where it does not form a loop then pulling it out from the edge in the same
manner to form a long loop or open binding ends, as described and for the purpose
specified.
