The object of this invention is to manufacture, in a cheap fabric, a
closer imitation of Brussels carpets. As is well known, an ordinary
Brussels carpet is made with a pattern on one side only, but according
to this invention, it is intended to produce a pattern on both sides
of the ingrain or pro-Brussels carpet, so that it will be reversible.
In manufacturing a reversible carpet of this class according to the
present invention, the pattern is formed by means of the warp and weft
combined, and any suitable ingrain warp operated by the harness or
jacquard of the loom may be used. In combination with ingrain warp, a
fine catching or binding warp, operated by the gear or jacquard
harness of the loom, is employed, such fine catching warp being used
to bind the weft into the fabric, therefore, if the fabric be woven
two-ply, the ingrain warps are thrown on both the under and upper
surfaces of the fabric, as well as in between the weft, according to
the pattern being woven, by which means four colors are shown on both
sides of the fabric, two being produced by the weft, and two by the
ingrain warps. More than four colors, however, can be produced upon
each side by multiplying the number of colored wefts and warps
employed. If the fabric woven be a three-ply, with the addition of the
ingrain warps thrown on each face of the fabric, then five or more
colors would be imparted to the carpet, as any number of colors can be
used to form a given pattern, by planting or arranging the colors in
the warp, and the remaining colors by the wefts, and so on. The
ingrain warp thread, therefore, together with the weft, used as stated
above, produces an effective pattern on both sides of the carpet;
consequently, it becomes reversible, and this can be accomplished
whether the carpet woven be two, three, or other number of ply. By
reference to the accompanying sheets of drawings, this invention will
be better understood. Fig. 1 is an enlarged cross section of an
improved carpet, a three-ply, that is to say, it is a carpet wherein
three shuttles are employed, each carrying a differently colored weft;
a represents the weft threads which may be composed of any suitable
fiber, b and c are cotton or other fine warp threads, which are
employed for binding the weft together, while d and e represent the
ingrain or woolen warp, where it will be seen that each ingrain warp,
besides lying between the weft, is thrown on both sides of the fabric,
for the purpose of forming figures thereon. It will, therefore, be
seen that a carpet made according to Fig. 1 will show five
colors--three colors produced by the weft and two colors produced by
the ingrain warp. Fig. 2 represents a carpet made with two-ply, in
which case only four colors will be produced, two by the weft and two
by the ingrain warp. It is, consequently, obvious that a carpet made
in the manner above described will have a corresponding pattern or
figure on both its sides, allowing it to be used on both sides. Fig. 3
also shows a two-ply carpet, but, in this case, six colors are
produced, i.e., two colors by the weft and four by the ingrain warp,
marked d, d¹, e, and e¹, the warp being so manipulated by the harness
as to make the carpet reversible, and having a corresponding pattern
or figure on both sides.--_Journal of Fabrics._
