[0001] The subject of the invention is a simple intertwined warp and weft fabric with the
weft consisting of a number of threads.
[0002] The innovation has a convenient and special application for fabrics which are preferably,
although not exclusively, for furnishing such as, for example, carpets or similar
fabrics.
[0003] The fabrics known at the present state of the technology are usually of a simple
weave (intertwining of warp and weft) which present the inconvenience of generally
being short-lasting and of limited resistance compared with results given by Turkish
or Persian knotting.
[0004] The scope of this invention is to eliminate the above-mentioned inconveniences.
[0005] This invention, according to the characteristics given in the attached claims, solves
the problem by realizing a fabric in simple weave which has the characteristics of
the weft having a number of threads inserted simultaneously, even though they may
be of different thicknesses, and their number and consistency being noticeably greater
than the thread or threads of the warp, the weft being selvaged in a continuous zig-zag
and the warp doubly weaving the weft while the weft singly weaves the warp, the consistency
of the weft being such that it remains rectilinear while the warp winds itsef round
it.
[0006] The advantages obtained from this solution consist essentially in the fact that the
fabric has a greater resistance longitudinally as the threads have been designed not
only to resist against the forces upon them, thereby reducing the relative wear, and
combined with an effect which is totally different from the usual one.
[0007] The following explanation gives more derails of the invention together with the help
of the drawings which give preferential solutions for realization, the execution details
of which are not to be held as limiting but only as examples.
[0008] Figure 1 shows the system of intertwining of the fabric; Figure 2 gives a layout
view of a defined part of the fabric; Figure 3 shows a section of the fabric in its
complete width.
[0009] As can be seen from the above figures, the invention consists in a fabric of simple
weave characterized by the weft having a number of threads inserted simultaneously
even though they may be of different thicknesses (la; lb; 1c; ...), the number and
consistency being noticeably greater than the thread or threads of the warp (2, 2'),
the weft being selvaged in a continuous zig-zag (1, 1'), and the warp (2; 2') doubly
weaving (a) the weft while the weft singly weaves (b) the warp, the consistency of
the weft (la; 1b; 1c;...) being such that it remains rectilinear while the warp (2;
2') winds itself around it.
[0010] As can be seen from figure 1 the fabric presents a weave that has a weft with a number
of threads (la; 1b; 1c;...) with a continuous zig-zag selvage (1, 1'), while the warp
consists of single contrary-woven threads (2, 2') which tie two bundles of weft at
a time.
[0011] For the sake of simplicity, Figure 1 shows only three weft threads whereas in reality
they are preferably more than that, and for convenience's sake in Figure 2 they are
six.
[0012] The weft threads are of a soft structure and up to 2-3mm in diameter in wool and
substitutes, while the warp threads are about 1mm in diameter and of a compact and
resistant material in cotton or a substitute.
[0013] Naturally, the execution details may be varied without altering the field of protection
of the invention defined by the characteristics given in the attached claims.
1. Fabric with simple weave for carpets, mats and similar in particular, characterized
by a weft made up of a number of threads inserted simultaneously, even though of different
thicknesses (la; lb; lc;...), being noticeably greater in number and consistency than
the warp (2; 2'), the weft having a continuous, zig-zag selvage (1, 1') and the warp
(2, 2') doubly weaving (a) the weft while the weft singly weaves (b) the warp, the
consistency of the weft (la; lb; lc;...) being such as to remain essentially rectilinear
while the warp (2, 2') winds itself around it.
2. Fabric according to claim 1. characterized by the fact that the weft threads are
of soft structure and with a diameter up to 2-3mm in wool and substitutes, while the
warp threads are about 1mm in diameter and composed of compact and resistant material
such as cotton or substitute.
