Improvements in Apparatus for Treating and Finishing Cut Pile
Fabrics, especially applicable to the Finishing of Fabrics Intended
to Imitate the Furs of Animals.
I FERDINAND BARTELS of the Firm of Bartels, Dierichs and Company, of
Barmen and Berlin, in the Empire of Germany, Merchants and Manufacturers, 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 and accompanying drawings:-
--
My said invention relates to improvements in apparatus for laying, smoothing
and imparting a gloss to cut pile fabrics, especially such fabrics as have a long
pile and are intended to imitate animal fur as is well understood. The apparatus as I
have designed it, is more especially suited to the treatment of long strips, of
imitation fur fabrics, such for example as might be used to trim garments.
A peculiarity of animal fur is that the hair always lies at a constant angle to the
skin, and has moreover a gloss or lustre, of its own, and both of these peculiarities
are difficult to imitate successfully in woven fabrics. The pile tends to stand
vertically from the foundation and has no inherent lustre.
My invention is intended to overcome these defects and the apparatus will be
best understood by a reference to the annexed two sheets of drawings.
On Sheet 1.
Fig. 1 is a side elevation of the apparatus partly in section to show the operation
more clearly.
On Sheet. 2.
Fig. 2 is a cross section of Fig. 1 at the line y y.
Fig. 3 is a plan view of the hot presser table or block, and Fig. 4 is an end view
of the same.
The whole apparatus is or may be mounted upon a bench or table A or other
suitable support. The fabric passing through the machine is clearly indicated in
the drawing, the foundation being markeds and the pile fibre f. Upon the
bench A secure brackets m m, and these brackets are formed at the top with
bearings which receive trunnions o o projecting from each side of the block a.
This block a has a cover b which is secured thereto by bolts as shown, and rests
and presses upon three or any other suitable number of gutters or runs rrr through
which the strips of fabric pass.
The faces of these gutters or runs are shown concave but they might be flat or of
other suitable formation.
The block a, cover band runs r are all heated by gas jets issuing from pipes 9 9,
which are supplied with gas or gas and air as indicated. The temperature of the
mass is regulated by observing the thermometer t fixed to the cover b. The fabrics
is fed through the machine in the direction of the arrows. First it passes over a
fixed or it might be a revolving brush n, with which it is kept in contact by the
hinged roller w.
The brush cleanses the pile from any foreign or loose material lodging in the
fibres. Next, the strip s passes into the heated run and as it passes through it is
pressed and ironed, all of the pile yarn being smoothed down to an augle similar
to that of fur. This hot pressing operation also imparts a gloss and lustre
similar to that of fur. On issuing from the run r, the fabric passes to drawing
rollers d. The lower roller is not driven but the upper roller receives motion by
means of a pitch chain k¹ which gears with a chain wheel 2 on the axis of the
roller.
The upper roller is weighted as shown so as to impart some pressure to the

page_text: fabric. The chain k receives motion from another chain wheel k on the axis of a
toothed wheel gearing with an intermediate wheel which is driven by a wheel =
on the driving shaft of the apparatus. The driving pulley, belt and belt-fork are
all shown and need not be described. To alter the speed at which the fabric is
pulled through the run r, it is only necessary to use change wheels between the
wheels and but any other suitable mode of varying the speed might be adopted.
According to the breadth of the block a, any greater or less number of runs
than three might be used and two or three blocks and runs might be placed
in line.
The heat, pressure and speed of the apparatus should be regulated and modified
in accordance with the material the nature of the dye and the strength of the fibre.
Although I have illustrated my invention as applied to the treatment of narrow
strips of pile fabric or imitation fur it will be understood that I might use a presser
run or block of sufficient width to treat wider piece goods of the nature set forth.
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.
1. The improved apparatus for smoothing and finishing pile fabrics intended to
imitate animal fur, in which the fabrics are passed through gutters or runs contained
in a covered block or in covered blocks heated by gas jets or other suitable means
substantially as herein before described and shown.
2. The general arrangement construction and combination of apparatus for
treating and finishing pile fabrics generally, and especially such pile fabrics as
are intended to imitate animal furs substantially as hereinbefore described and
shown.
