AN IMPROVED CONSTRUCTION APPARATUS FOR HOT-PRESSING WOVEN FABRICS
Year: 1885

page_text: WOVED Fabrics.
I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane
in the County of Middlesex Consulting Engineer and Patent Agent, do hereby
declare the nature of my invention for "AN IMPROVED CONSTRUCTION
APPARATUS FOR HOT-PRESSING WOVEN FABRICS" to be as follows:-
tr
OF
In many branches of the silk, cotton and wool industries the so-called cylinder-
press with mould has for many years past gradually replaced the ordinary
papering" press, but without producing so good an effect on the fabric as was
attained by the latter. This arises from the fact that during the operation with
the papering press the pressing is effected under the application of heat and then,
while still subjected to the same pressure, the goods are cooled.
With the cylinder
press the cooling is effected in the absence of all pressure.
The present invention relates to a construction of revolving "papering" press
whereby the advantages afforded by the fixed papering press are more or less
obtained.
The construction of the press is shewn in sectional elevation at Fig. 1 of the
accompanying drawings. It consists of two cylinders A and B of ordinary con-
struction, round which passes an endless web m lined with the pressing paper or
equivalent material, and which is kept tightly stretched by the adjustment of the
cylinders A and B, so that the pressure exercised by it upon the cylinders is
considerable. The material of which the endless web is constructed will vary
according to the nature and dressing of the material to be treated, it may be of
leather, sheet metal, caoutchouc, sail cloth, oil cloth &c. The "lining" for effecting
the "papering" may be of paper, metal, silk impregnated with suitable substances
or other suitable flexible materials with glazed surface.
It should be of such a nature that it does not crease, warp, stretch or tear in
working.
For producing the required tension of the endless web and corresponding
pressure between it and the cylinders, the bearings of the latter, which are made
to slide, are forced asunder by bydraulic pressure, screw, or lever action.

page_text: In order to avoid undue strain being put upon the trunnions of the cylinders, a
third cylinder C is interposed between them, running in fixed bearings, upon
which cylinder paper or other fabric is wound so as to adjust its diameter to the
exact distance between the cylinders A and B, so that these are made to take a
bearing upon the cylinder C and thus their trunnions are relieved of pressure.
The fabric n to be treated is wound upon the beam D and is passed between the
cylinders C and A and between the web m and the surface of cylinder A; thence
it is carried over to cylinder B and is eventually wound up on beam E.
The cylinders A and B may both be heated internally by any suitable known
means, but in order to obtain the above described effect of the ordinary papering
press, the one cylinder, B for instance, is kept cold, being artificially cooled if
requisite by circulation of cold water.
The fabric n will then first be subjected to pressure under the influence of heat
by the cylinder A, and after passing in contact with the air on its way from A to B,
will be effectually cooled by contact with B while still subject to the same pressure.
Should it be desired to increase the pressure, or to act upon the outer surface of
the fabric, other pressing cylinders or rollers a, b, c, d, e, either cold or heated, may
be applied against the cylinders A and B:
If desired a steaming or glazing cylinder F may be introduced between A and B,
and the machine may be otherwise variously modified as regards the number and
position of the cylinders &c; thus it may consist only of the cylinder A, the
endless web and a guide roller for stretching the latter. Fig. 4 shews the same
arrangement as at Fig. 1 but with the omission of the cylinder C.

I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane
in the County of Middlesex, Consulting Engineer and Patent Agent 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
In many branches of the silk, cotton and wool industries the so-called cylinder-
press with mould has for many years past gradually replaced the ordinary
papering press, but without producing so good an effect on the fabric as was
attained by the latter. This arises from the fact that during the operation with
the papering press the pressing is effected under the application of heat and then
while still subjected to the same pressure the goods are cooled: With the cylinder
press the cooling is effected in the absence of all pressure.
The present invention relates to a construction of revolving "papering" press
whereby the advantages afforded by the fixed papering press are more or less
obtained.
The construction of the press is shewn in sectional elevation at Fig. 1 of the
accompanying drawings. It consists of two cylinders A and B of ordinary con-
struction, round which passes an endless web m lined with the pressing paper or
equivalent material, and which is kept tightly stretched by the adjustment of the
cylinders A and B, so that the pressure exercised by it upon the cylinders is
considerable. The material of which the endless web is constructed will vary
according to the nature and dressing of the material to be treated; it may be of
leather, sheet metal, caoutchouc, sailcloth, oil cloth &c. The "lining" for effecting
the "papering" may be of paper, metal, silk, impregnated with suitable substances
or other suitable flexible materials with glazed surface.
It should be of such a nature that it does not crease, warp, stretch or tear in
working.
For producing the required tension of the endless web and corresponding
pressure between it and the cylinders, the bearings of the latter, which are made
to slide, are forced asunder by hydraulic pressure, screw, or lever action.
In order to avoid undue strain being put upon the trunnions of the cylinders,
a third cylinder C is interposed between them, running in fixed bearings, upon
which cylinder paper or other fabric is wound so as to adjust its diameter to the
exact distance between the cylinders A and B, so that these are made to take a
bearing upon the cylinder C and thus their trunnions are relieved of pressure.
The fabric n to be treated is wound upon the beam D and is passed between the
cylinders C and A and between the web m and the surface of cylinder A; thence.
it is carried over to cylinder B and is eventually wound up on beam E.
The cylinders A and B may both be heated internally by any suitable known
means, but in order to attain the above described effect of the ordinary papering
press, the one cylinder, B for instance, is kept cold, being artificially cooled if
requisite by circulation of cold water,

page_text: The fabric n will then first be subjected to pressure under the influence of heat
by the cylinder A, and after passing in contact with the air on its way from A to B,
will be effectually cooled by contact with B while still subject to the same pressure.
The desired effect will be produced with all the greater perfection, the more
accurately the dimensions of the cylinders and their distances apart are pro-
portioned to the temperature employed.
Should it be desired to increase the pressure, or to act with greater pressure upon
the outer surface of the fabric, other pressing cylinders or rollers a b, c, d, e, either
cold or heated, may be applied against the cylinders A and B.
If desired, a steaming or glazing cylinder F may be introduced between A and B,
as shewn at Fig. 2, and the machine may be otherwise variously modified as
regards the number and position of the cylinders &c; thus it may consist only of
the cylinder A, the endless web and a guide roller for stretching the latter.
Fig. 4 shews the same arrangement as at Fig. 1 but with the omission of the
cylinder C.
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
1. The construction of rotating papering press for woven fabrics, consisting of
an endless papering belt m travelling over one or more heated cylinders over which
it is tightly stretched so as to subject to the requisite pressure the fabric to be
treated while this passes between its inner surface and the outer surface of the
cylinders.
2. The use for producing the requisite tension of the papering band, of a
cylinder C interposed between the cylinders A and B, so as to relieve their
bearings of pressure, the diameter of the cylinder C being adjusted by winding
more or less paper or other fabric thereon, substantially as herein described.
3. The construction of a rotating papering press wherein one cylinder A is
heated while another cylinder B is cooled, so as to subject the fabric successively to
a heating and a cooling action while passing over the cylinders, substantially as
herein described.
4. The construction of a rotating papering press wherein one cylinder A is a
heating cylinder, a second cylinder F is a glazing cylinder, and a third cylinder B
is a cooling cylinder, substantially as herein described.
