We, PATRICK MOIR-CRANE of Mersoy Bank Didsbury in the County of Lancaster
Oil Manufacturer and FREDERICK WILKINSON of Thorncliffe Withington in the said
County Yarn Agent do hereby declare the nature of said Invention for IMPROVE-
MENTS IN THE MANUFACTURE OF CORRUGATED PAPER AND ANALOGOUS MATERIALS
OR FABRICS, to be as follows:-
11
Our invention relates to improvements in the manufacture of corrugated or fluted
paper or other similar fabric from paper pulp wood or straw pulp or other analogous
materials and consists chiefly in corrugating or fluting preferably by means of
corrugated or fluted rollers the paper or other fabric while still in the pulp state in
such manner as to produce when the pulp bas set or hardened a fabric with
corrugations or flutes extending across its full width and which will withstand
considerable pressure without the corrugations losing their shape and character.
We are aware that paper has been stamped or ombossed after manufacture so as
to produce corrugations but in this case owing to the manufacture of the paper
having been first completed the corrugations have had no permanent character and
it has been necessary to attach a thin sheet of paper to one side of the main sheet in
order to prevent the corrugations being pressed or flattened out.
Wo are also aware
that paper or paper pulp has been rolled so as to produce indentations or protuberances
on both sides of the fabric and we therefore desire to disclaim all intention of including
such fabrics in this our Invention.
Our improved corrugated or fluted fabric which is made from pulp before it has
set or hardened and is corrugated or fluted across the entire width of the sheet is
particularly adapted for packing bottles and other fragile articles for lining carpets
and for many other uses too numerous to specify.

We, PATRICK MOLR-CRANE of Mersey Bank Didsbury in the County of Lancaster
Oil Manufacturer and FREDERICK WILKINSON of Thorncliffe Withington in the said
County Yarn Agent, do hereby declare the nature of said Invention for IMPROVEMENTS
IN THE MANUFACTURE OF CORRUGATED PAPER AND ANALOGOUS MATERIALS OR
FABRICS, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to improvements in the manufacture of corrugated or fluted
paper or other similar fabric from paper pulp wood or straw pulp or other analogous
materials and consists chiefly in corrugating or fluting preferably by means of
corrugated or fluted rollers tho paper or other fabric while still in the pulp stato in
such manner as to produce when the pulp has set or hardened a fabric with
corrugations or flutes extending across its full width and which will withstand
considerable pressure without the corrugations losing their shape and character.
And in order that our Invention may be fully understood and readily carried into
effect wo will describe the accompanying Sheet of Diagrams reference being had to
the figures and lotters marked thereon.
Figure 1 represents in outline a suitable construction of machine for the purposes
of our Invention and Figs. 2 and 3 illustrate a specimen of corrugated material or
fabric made according to our Invention.
In Fig. 1. a a, a¹ a², a² a², a³ a³ represent four pairs of squeezing rollers; b b₁ b³
and c c c c are endless webs of woven wire cach of which while the machino is
working is kept constantly travelling over guide rollers d and d' respectively and
between one or other of the pairs of squeezing rollers. Motion is imparted to the
lower endless webs band to the upper webs e c² ² c³ and to the squeezing rollers
by any convenient incans and all are preferably driven at or about the same surface
speed. The upper endless webs c c² are weighted by rollers e el the journals of which
are guided in slots in the framing. The corrugated or fluted rollers g g are gearod
together and driven at the required surface speed by a belt from the last pair of
squeezing rollers or otherwise.
In operation the pulp from the rag engine is fed into the machine or placed upon
the first lower travelling web b at or about the point X and as the pulp is carried
forward by the web bit receives a slight preliminary pressure from the upper web c
weighted by the rollers e which pressure helps to spread and consolidate the pulp
before it reaches the first pair of squeezing rollers a a. From the rollers a a tho
sheet of pulp passes over the end of the web bon to the web and between the second
pair of squeezing rollers a' a' and thence under the weighted web to the third pair
of squeezing rollers a a² over the end of the web on to the web 62 and between
the last pair of squeezing rollers a³ a³ from which it is carried by the web b² through

page_text: the rollers g g by which it is corrugated or fluted and then allowed to dry and sot
whereby the corrugations become permanent and render the material very strong.
Our improved corrugated or fluted fabric which is made from pulp before it has
set or hardened and is corrugated or fluted across the entire width of the shoot is
particularly adapted for packing bottles and other fragile articles for lining carpets
and for many other uses too numerous to specify.
Although a machine such as that described and illustrated by the Diagram would
accomplish the object of our Invention any other machine suitable for the purpose
may be employed and the details may be varied or modified as found advantageous
or desirable. For example any number of steam heated cylinders night be employed
to partially dry the pulp before it reaches the corrugated or fluted rollers gg. The
said rollers may be fluted in lines parallel to their axes or spirally diagonally or
transversely so as to produce any required pattern of corrugations on the sheet
of pulp.
We are aware that paper has been stamped or embossed after manufacture so as to
produce corrugations but in this case owing to the manufacture of the paper having
been first completed the corrugations have had no permanent character and it has
been necessary to attach a thin sheet of paper to ono side of the main shoet in order
to prevent the corrugations being pressed or flattened out. We are also aware that
paper or paper pulp has been rolled so as to produce indentations or protuberances on
both sides of the fabric and we therefore desire to disclaim all intention of including
such fabrics in this our Invention.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
wo claim is
1. The manufacture of corrugated paper and analogous materials or fabrics by
corrugating or fluting partially dried pulp and then drying the same to allow the
corrugations to set and harden for the purposes specified.
2. Corrugated paper material or fabric manufactured from partially dried pulp
substantially as and for the purposes herein set forth.
