An Improved Printers' Blanketing, applicable to other purposes.
I FRANK REDDAWAY of Cheltenham Street, Pendleton, in the County of Lancaster,
Manufacturer of Machine Belting do hereby declare the nature of this invention to
be as follows:
My said invention relates to an improved woven fabric specially suitable for use as
blanketing for calico printers and also applicable for other purposes where a thick
elastic fabric is a desiratum. For printers' blanketing it is requisite to use a material
which will be soft, elastic and even in thickness and quality so as to give every facility
for printing the goods while obviating the possibility of injury to the engraved or
other printing surfaces. Accordingly material for this purpose has usually been
manufactured by cementing together several thicknesses of woven material the cement
used being usually india rubber. Such material is liable to various irregularities and
disadvantages not conducive to perfect working.
According to my invention I weave a homogeneous blanketing of the requisite
thickness and having the desired elasticity and softness. The fabric is woven from
very fine counts of cotton yarn. In practice I find that 60 to 100 count yarns are
the best to use for my purpose.
In weaving the fabric I employ a twelve shaft loom the warp yarns being split
and the weft picks shot in succession in different planes so as to give the desired
thickness. The fineness of the yarn and the closeness with which the weft can be
beaten up gives a tough and even texture combined with a softness, elasticity and
body which eminently fit it for the designed purposes. Although I have indicated
a twelve shaft loom as a suitable mechanism for producing the fabric, it will be
evident to practical weavers that the material can be woven by other mechanism
for example by using a dobby or by any means which would split the warp yarns
the required successive number of times.
The improved fabric might be used for other purposes where its peculiar qualities
would prove of advantage. For example it might be utilised as a foundation to receive
the wire dents of card clothing. Such foundation material is usually made by
cementing several thicknesses of fabric together with india rubber whereas my
improved fabric would give a homogeneous foundation with all of the required
qualities. In weaving a card foundation according to my invention I might weave
the central part of wool or animal fibre and throw up a linen face on either or on both
sides. The upper side of the foundation might receive a coating of rubber as is usual.
My improved fabric might also be used for other purposes.

An Improved Printers' Blanketing, applicable to other purposes.
I FRANK REDDAWAY of Cheltenham Street, Pendleton, in the County of
Lancaster, Manufacturer of Machine Belting, 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 an improved woven fabric specially suitable for use as
blanketing for calico printer's and lithographer's purposes. For printer's blanketing
it is requisite to use a material which will be soft, elastic and even in thickness
and quality so as to give every facility for printing the goods while obviating the
possibility of injury to the engraved or other printing surfaces. Accordingly
material for this purpose has usually been manufactured by cementing together
several thicknesses of woven material the cement used being usually india rubber.
Such material is liable to various irregularities and disadvantages not conducive to
perfect working.
According to my invention I weave a homogeneous blanketing of the requisite
thickness and having the desired elasticity and softness. The fabric is woven from
very fine counts of cotton yarn. In practice I find that 40 to 80 or 100 count yarns
are the best to use for my purpose. use the same count of yarn both for the warp
and the weft but do not confine myself in this respect. I use yarn of good quality
and I prefer to use yarn which has been cleaned and gassed. In weaving the fabric
I employ a twelve shaft loom the warp yarns being split and the weft picks shot in
succession in different planes so as to give the desired thickness. The fineness of the
yarn and the closeness with which the weft can be beaten up gives a tough and even
texture combined with a softness, elasticity and body which eminently fit it for the
designed purposes.
In order that the method of weaving may be more clearly understood I have
attached hereto a copy of the draft which I have used when weaving with twelve
shafts and twenty four picks to the round. When weaving according to my inven-
tion I have drawn 155 warp ends through each inch in length of the reed and put
in 150 picks to each inch of cloth woven, about 50 picks appearing in each of the
two faces of the cloth so that the cloth counts about 50 by 50 to 54 per square
inch. This gives a cloth having a suitably fine and even surface. It must however
be understood that I bave furnished the draft by way of example and may vary the
method of weaving so long as I produce a thick elastic cloth having a fine even
close woven face on each side. Although I have indicated a twelve shaft loom as a
suitable mechanism for producing the fabric it will be evident to practical weavers
that the material can be woven by other mechanism for example by using a dobby
or by any means which would split the warp yarns the required successive number
of times.
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 printers blanketing produced from the material herein indicated in the manner
and substantially as set forth
