PROVISIONAL SPECIFICATION..
Improvements in Apparatus for Raising the Pile or Nap of Woven
Fabrics.
I, ANDREW GREENHALGII, of Clough Bleach Works, Radcliffe, near Manchester,
in the County of Lancaster, Bleacher and Finisher, do hereby declare the nature
of this invention to be as follows:-
This invention relates to that class of machines (employed for finishing or
raising the nap or pile of woven fabrics made of wool, cotton, or mixed fibre)
which consist of a certain number of rollers covered with card filleting, and
which are rotated rapidly in contact with the cloth of which the nap or pile is
to be raised.
A well-known defect in the operation of these machines is that they have a
tendency to produce streaks or lines on the raised surface in a longitudinal
direction, and the object of this invention is to remedy the effect above mentioned
and to produce a face of a superior quality without any lines or streaks what-
ever.
For this purpose I employ an additional card covered roller (or rollers) working
in connection with the taking off roller of the machine, the cloth running between
the two, so that the additional roller (or rollers) is (or are) driven by the contact
of the cloth, at the same surface speed, or the additional roller or rollers may be
driven positively at a slower or faster speed if preferred.
This additional card covered roller, besides its revolving motion, has also
imparted to it a reciprocating endwise motion which causes it effectually to take
out any longitudinal streaks or lines which may have been caused by the machine
and to impart to the nap of the cloth a greatly improved appearance or finish.
The reciprocating endwise motion may be given to the additional card covered
roller (or rollers) by means, of an inclined disc or cam at or near one end of the
axle or in any other simple and convenient manner.

Improvements in Apparatus for Raising the Pile or Nap of Woven
Fabrics.
I, ANDREW GREENHALGHI, of Clough Bleach Works, Radcliffe, in the County
of Lancaster, Bleacher and Finisher, 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:

page_text: raising the nap or pile of woven fabrics made of wool, cotton, or mixed fibre)
which consist of a certain number of rollers covered with card filleting, and
which are rotated rapidly in contact with the cloth of which the nap or pile is
to be raised,
The nature and object of my said invention and the manner in which the same
is to be performed or carried into practical effect will be readily understood on
reference to the two sheets of drawings hereunto annexed and the following
explanation thereof.
On Sheet 1 of the drawings, Fig. 1 is a side elevation of a finishing or nap
raising machine with my improvement shewn as applied thereto, and Fig. 2 is
a partial plan view of the same.
On Sheet 2 of the drawings Fig. 3 is an end view, and Fig. 4 a partial plan
view of the same, a being the framing of the machine, 6 the main cylinder or
bed-roller, and the series of card covered rollers.
A well known defect in the operation of these machines is that they have a
tendency to produce streaks or lines on the raised surface of the fabric in a longi-
tudinal direction, and the object of this invention is to remedy the defect above
mentioned and to produce a face of a superior quality with a more erect pile,
and without any lines or streaks whatever.
For this purpose I employ an additional card covered roller (or rollers) d
working in connection with the taking-off roller e of the machine, the cloth
running between the two so that the additional roller (or rollers) d is (or are)
driven by the contact of the cloth, at the same surface speed, or the roller (or
rollers) may when treating stout fabrics, be driven positively at a slower or
faster speed, as may be preferred, by means of an endless cord or band passing
round one of the grooves of the pulley f at or near one end of the axle thereof.
This additional card covered roller d, besides its revolving has also preferably
imparted to it a reciprocating endwise motion which causes it effectually to take
out any longitudinal streaks or lines which may have been caused by the
machine, and to impart to the nap of the cloth a greatly improved appearance
or finish.
The reciprocating endwise motion may be given to the additional card covered
roller (or rollers) d by an inclined disc or cam g at or near the other end of the
axle, a fixed pin or roller h running in the inclined groove of the same or in
any other simple and convenient manner; or in some cases the endwise motion
may be dispensed with in which case the card covered roller d being positively
driven will pick up the nap and leave it in a more erect position.
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:
-
The improvement applicable to the herein before indicated class of machines for
finishing woven fabrics consisting in the combination with the taking-off roller
of such machine of an additional card covered roller (or rollers) either driven
by contact with the fabric or independently driven at a different speed, and either
with or without a reciprocating endwise motion substantially as herein before
described and illustrated by the drawings annexed.
