The present invention relates to textile pile
I fabrics and method for making same, and par
ticularly to carpets and rugs having decorative
designs formed in relief on the face of the fabric.
An object of this invention is to provide an im
proved and novel method for making pile fabrics
of the character mentioned, whereby a three tone
effect is obtained in a carpet, using but a single

stance on the high wires, The density of the pile‘
. yarn and the ‘closeness of weave, causes the low
pile loops thus formed to overlap the empty rows.
- 'I'he'pile areas marked “B" are obtained by
having double strands of pile yarn raised by the
loom on the high wires; no pile being raised in
this instance on the low wires. ‘When said high
wires
are withdrawn, as known in the art, such
color yarn as pile material.

high loops are cut to form tuft which splays;
