Improvements in Waterproof Fabrics.
We, LOUIS FRANKENSTEIN, of the Firm of P. Frankenstein & Sons, of Miller
Street, Manchester, in the County of Lancaster, Waterproof Manufacturers, and
CHARLES LYST, of the same place, Manager, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the manufacture of double texture waterproof fabrics
and is designed to provide for the more perfect and more economical attachment
of the two fabrics together to form the finished cloth with the rubber proofing
between.
Hitherto it has been customary to coat the surfaces of both fabrics with the
rubber proofing and to bring the two proofed surfaces together to cause them to
adhere. We find that the two fabrics can be caused to adhere and better results
obtained by only coating one fabric with the proofing and then pressing the
unproofed fabric into contact with the proofing on the proofed fabric while the last
coat is still tacky or sticky.
Our invention accordingly consists essentially in the process or method of pre-
paring or manufacturing double texture fabrics by applying or spreading the
required weight of the rubber proofing coat by coat to one fabric the last coat being
of very tacky or sticky nature or consistency and then pressing the unproofed
fabric against the proofed surface of the other before drying whilst still in a tacky
or sticky condition. Also in apparatus therefor.
In carrying out the invention we spread one of the fabrics in the usual way
with one, two, three or more coats of the rubber dough used in proofing. Over these
we then spread a final or sticking coat of rubber dough or proofing on other suitable
sticky material such coat being of a sufficiently sticky or tacky nature as to subse-
quently adhere to the surface of the other fabric when brought into contact with it.
For this purpose we construct a spreading machine with rollers and gauge but
without any drying table and with this we combine a set of one, two or more
doubling rolls and a stand, rollers, or equivalent to hold the unproofed fabric and
rollers or equivalent mechanism to take away or fold up the finished fabric.
It will be obvious however that instead of using a specially constructed spreading
and doubling machine the fabric may be run through an ordinary spreading
machine and then through a doubling machine without the last coat being allowed
to dry.

We, LOUIS FRANKENSTEIN, of the Firm of P. Frankenstein & Sons, of Miller
Street, Manchester, in the County of Lancaster, Waterproof Manufacturers, and
CHARLES LYST, of the same place, Manager, 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 relates to the manufacture of double texture waterproof fabrics
and is designed to provide for the more perfect attachment of the two fabrics
together to form the finished cloth with the rubber proofing between.
Hitherto it has been customary to coat the surfaces of both fabrics with the
rubber proofing and to bring the two proofed surfaces together to cause them to
adhere. We find that the two fabrics can be caused to adhere and better results
obtained by only coating one fabric with the proofing and then pressing the
unproofed fabric into contact with the proofing on the proofed fabric while the last
coat is still tacky or sticky.
Our invention accordingly consists essentially in the process or method of pre-
paring or manufacturing double texture fabrics by applying or spreading the
'required weight of the rubber proofing coat by coat to one fabric the last coat being
of very tacky or sticky nature or consistency and then pressing the unproofed
fabric against the proofed surface of the other before drying whilst still in a tacky
or sticky condition.
It will be fully described with reference to the accompanying drawing which
illustrates a longitudinal sectional elevation of apparatus designed for the purpose.
In carrying out the invention we spread the fabric A with one, two or three (or
any greater number as may be required) coats of the rubber dough used in proofing.
This is done in the ordinary way and by the, machine at present in use for the
purpose.
The fabric A is then brought to a machine preferably arranged and constructed
as illustrated. and over the surface already proofed we spread a final or sticking coat
of rubber dough or proofing (or other suitable sticky or tacky material). This
final coat is of a sufficiently sticky or tacky nature as to subsequently cause to
adhere thereto the-surface of another fabric when brought or pressed into contact
with it.
For this purpose we construct a machine as shown in the drawing with spreading
roller B and knife or gauge C but without any drying table. Behind these we
place a pair of doubling rollers D, a stand E to hold the unproofed cloth or fabric F
and guide rollers f. Also in a suitable position a roller G to roll up the doubled
or finished fabric. A second pair of doubling rollers may be placed between the
roller B and the rollers D; or between the rollers D and the roller G if thought
desirable. The rollers B and D) and the stand E may be set closer together but
the arrangement shown we consider works better as it allows for the examination
of the cloth as the operation proceeds.
In operation the coated fabric A is placed on the stand H and passed between
the roller B and gauge C where it receives the final coat of proofing and from
thence it is led forward between the doubling rollers D without any drying of the
last coat of proofing. The unproofed fabric F from the stand E is stretched by the
guide rollers f and also carried forward to the doubling rollers D where it is
brought into contact with the newly proofed surface of the fabric A while still
wet and the two are pressed together and wound up upon the roller G. The fabric
is subsequently dried and vulcanized by dry heat in the usual way.
It will be obvious however that instead of using a specially constructed spreading

page_text: and doubling machine the fabric may be run through an ordinary spreading
machine and then through a doubling machine without the last coat being allowed
to dry.
The following advantages are obtained by this invention;-
1. Open cloths can be employed for lining without showing any rubber proofing
through on to the finished side which has hitherto been the case in the ordinary
method of proofing.
2. A better finish on the lining or inner side of the cloth and a softer feel to the
finished fabric.
3. A more uniform-proofing and less liable to flaws is obtained by applying all
the coats of rubber to one cloth and the fabric is thereby rendered more uniformly
waterproof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
:―
1. The process or method of preparing or manufacturing double texture water-
proof fabrics consisting in applying or spreading the required weight of the
proofing coat by coat to one fabric only the last coat being of a sufficiently sticky
or tacky nature and before drying this last coat applying thereto an unproofed
fabric and causing it to adhere substantially as described.
2. The process or method of manufacturing double texture waterproof fabrics
substantially as described.
3. The apparatus for the manufacture of double texture waterproof fabrics
constructed and arranged substantially as described and shown.
