. I, RUDOLF SCHWARTZ, of 160, Ostwall, Crefeld, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a method for producing figured nap in which the
pile threads at the places devoid of nap are used for producing either frieze, or
mirror effects or both together.
Hitherto it has been customary to use only a single pile thread for producing
the above named goods on double backed velvet looms and such single pile-
thread was evenly woven in the upper and lower backing of the goods and was
used both for forming the cut nap as also the frieze or mirror effect. This
however has the disadvantage of the frieze and mirror effects of special patterns
being produced both on the upper as well as on the under surface by only one half
of the pile threads so that these latter appear spaced too far apart and do not
show a uniform close pattern.
According to the improved method two pile warps are used the one of which
is embedded both in the under and in the upper backing and forms the cut nap
for both besides also forming the frieze or mirror effect for one of them while the
other pile warp is merely embedded in the other backing so as to form the
frieze or mirror effect therefore. Thus the formation of the frieze or mirror
effect both on the upper and under surface is effected by the same number of
pile threads as are used for the cut nap so that necessarily a fully furnished
pattern is produced.
The pile warp are imbedded both in the upper backing as also in the under
backing and this forms the cut nap for both parts. Furthermore it forms in the
under backing, by means of specially thick frieze-picks which after weaving
are pulled up in a well known manner, the frieze effects as well as the mirror
effects.
If desired only frieze effects or only mirror effects may be produced on any
one of the surfaces.
The ground or main warp are caused to bind in any suitable manner.

in and by the following statement:-
This invention relates to a method for producing figured nap in which the
pile threads at the places devoid of nap are used for producing either frieze, or
mirror effects or both together.
Hitherto it has been customary to use only a single pile-thread for producing
the above named goods on double-backed velvet looms, such single pile-thread
being evenly woven in the upper and lower backing of the goods and used both
for forming the cut nap as also the frieze or mirror effect. This however has
the disadvantage that the frieze and mirror, effects of special patterns are
produced both on the upper as well as on the under surface by only one half
of the pile threads so that these latter appear spaced too far apart and do not
show a uniform close pattern.
According to the improved method two pile warps are used the one of which
is imbedded both in the under and in the upper backing and forms the cut, nap
for both as well as forming the frieze or mirror effect for one of them; while
the other pile warp is merely imbedded in the other backing so as to form the
frieze or mirror effect therefore. Thus the formation of the frieze or mirror
effects both on the upper and under surface is effected by the same number of
pile threads as are used for the cut nap so that necessarily a fully furnished
pattern is produced.
The invention is illustrated diagrammatically in the accompanying drawing.
The pile warp d is embedded both in the upper backing a and also in the
under backing 6 and forms the cut nap z for both parts. Furthermore it forms
in the under backing, by means of specially thick frieze-picks which after wear-
ing are pulled up in a well known manner, the frieze effects y as well as the
mirror effects z.
If desired only frieze effects or only mirror effects may be produced on anyone
of the surfaces.
The ground or main warps which for the sake of greater clearness have been
omitted from the drawing are caused to bind in any suitable manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
:-
L. →
A method of producing figured pile goods presenting frieze or mirror effects
on double backed velvet looms, characterized in that two pile warps are employed
one of which is imbedded both in the under and upper backing so as to form the
cut nap for both and also the frieze and mirror effect for one of the surfaces, while
the other pile-warp is merely imbedded in the other backing so as to form the frieze
and mirror effect therein without however being used for the cut nap of the
same.
