Improved Means and Appliances to be Employed in Finishing
Imitation Skins, Plushes, Velvets, and other Cut Pile Fabrics.
I HERBERT ANDERTON FOSTER of Black Dike Mills Queensbury in the County
of York Spinner and Manufacturer, do hereby declare the nature of this invention to
be as follows:-
"
This Invention consists of improved means and appliances to be employed in the
finishing" processes practised in the manufacture of imitation skins, plushes velvets
and other like cut pile fabrics the object being to facilitate the processes and to secure
a higher degree of "finish" and lustre.
I attain the above objects by submitting the fabric to the action of a blast or
current of compressed air discharged through the backing or foundation of the picce
and through the pile the object being to raise and lift the pile as also to straighten
and disentangle any divergent fibres.
"
The several finishing processes to which the Invention is applicable are the
batting" the "cropping" and the brushing or last stage of finishing.
In the batting the application of compressed air greatly facilitates the process, in
the cropping the action and effect of the air upon the pile is to straighten it for the
knives and in the brushing or last stage of the finishing the effect of the application
of compressed air is to thoroughly straighten and raise all the minute divergent
fibres whereby there is obtained a "filling in" and increased lustre imparted to the
fabric arising from the fibres being brought back to their natural condition an effect
heretofore produced in the trade by what is known as "hanging" that is hanging up..
the piece on poles or frames and exposing the pieces to the action of air at a low
temperature for a considerable period.
The apparatus I have found suitable and convenient of application, consists of a
perforated pipe over which the back of the piece is passed the air being supplied from
an air vessel charged by any ordinary compressor but I do not limit or confine
myself to the use of a perforated pipe, as it is obvious there are various devices
by which the air current could be directed to and passed through the piece
and pile.

1, HERBERT ANDERTON FOSTER of Black Dike Mills, Queensbury in the County of
York, Spinner and Manufacturer, 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:-
This Invention consists of improved means and appliances to be employed in the
"finishing" processes practised in the manufacture of imitation skins, plushes velvets
and other like cut pile fabrics, the object being to facilitate the processes and to
secure a higher degree of "finish" and lustre.
I attain the above objects by submitting the fabric to the action of a blast or
current of compressed air discharged through the backing or foundation of the piece
and through the pile as also to straighten and disentangle any divergent fibres.
The several finishing processes to which the invention is applicable are the

"batting" and "cropping" and the "brushing" or last stage of finishing. In the
batting the application of compressed air greatly facilitates the process, in the "cropping"
the action and effect of the air upon the pile is to straighten it for the knives, and in the
brushing" or last stage of the finishing the effect of the application of compressed
air is to thoroughly straighten and raise all the minute divergent fibres whereby there
is obtained a " filling in and an increased lustre is imparted to the fabric arising
from the fibres being brought back to their natural condition an effect heretofore
produced in the trade by what is known as "hanging" that is hanging up the piece
on poles or frames and exposing the pieces to the action of air at a low temperature
for a considerable period.
The apparatus I have found suitable and convenient of application, consists of a
perforated pipe over which the back of the piece is passed the air being supplied from
an air vessel charged by any ordinary compressor..
Such being the nature and object of the said invention the following is a complete
description of same reference being had to the accompanying drawings in which:-
Such an apparatus is shewn in Figs. 1 and 2, representing in section a perforated pipe
and Fig. 3 angle plates having a slit or perforations, Fig. 4 illustrates an enlarged
view of an "end" of the pile and its divergent fibres, Fig. 5 illustrates the effect
of the air in laying or condensing the finer fibres which were divergent from the
core or body of the "end."
At 1 is the pipe charged or supplied with compressed air, 2 is the fabric passing
over the pipe 1, and perforations 3 in the direction shewn by the arrow, and in such
manner that the blast of air completely penetrates and passes through the whole of
the fabric and being applied to the backing of the piece, the blast passing in the
direction of the "stand" and length of the pile as shewn by the arrows in Figs. 4
and 5) and surrounding as it does, each and every separate "end," of the pile, there
is thus applied along the whole length of the pile a wind brush" which diverts
and turns all fibres which would otherwise be divergent into the desired direction is
efficacious and thorough in its action and of ready application, I do not however
limit or confine myself to the use of a perforated pipe as it is obvious there are
various devices by which the air current could be directed to and passed through
the piece and pile.
Such for example as plates arranged at an angle or shaped the plates being
slightly apart so as to leave a fine longitudinal slit or orifice for discharge of air.
Nor do I confine myself to the use of an air vessel and air compressed within a
container as it is obvious a fan or blower may be employed for furnishing the requisite
supply of air, there is however the advantage in taking the supply of. pipes from an
air vessel that the supply to any one of a series of machines or appliances is obtained
and shut off by the simple movement of a tap or valve such as shewn at 4.
I have not found in practice an advantage in any special size of pipe over which the
piece is to be passed nor in the size of hole perforations or slits through which the
air is discharged.
So long as it is provided that a sufficient current is kept up the desired result
is obtained.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The use and application of improved means and appliances employed in finishing
imitations skins, plushies, velvets and other cut pile fabrics and operating as and for
the purposes herein fully described..
