Improvements in Machinery for the Manufacture of Packing and
Lining Materials.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex 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 machines for manufacturing packing and lining materials.
The said invention is more particularly designed for producing packing material
consisting of a sheet or strip of fluted or corrugated paper affixed to a sheet or strip of
plain paper or similar material so as to form an elastic fabric.
Heretofore in such machines only two corrugated rollers have been used to produce
the corrugated sheet and such rollers have to be moved slowly in order to insure the
making of corrugations of sufficient depth and permanency, and the paste or adhesive
substance for securing the sheets together is usually applied so as to entirely coat one
surface of the plain sheet, while only a portion of such surface can be brought in.
contact with the corrugated piece, thus causing waste of the paste and supplying an
extra mass to be dried out before the paper is in condition for use.
The present invention is partly designed to overcome these defects and to provide a
machine which will produce the necessary indentations upon the strip of paper to be
fluted or corrugated; and give such corrugations permanent set without breaking or.
cutting the paper while at the same time allowing rapid motion of the corrugating.
rollers.
The said invention is also designed to provide for applying the paste or other
adhesive material by which the fluted and plain strips of paper are held together in
such a manner that the time necessary for drying the same is considerably shortened
and waste of the adhesive material is prevented.
The said invention moreover comprises other improvements hereinafter described.
In the accompanying drawings I have shown how the said invention may be con-
veniently and advantageously carried into practice.
and

Figure 4 is an isometric view of the same also drawn to an enlarged scale.
A is the frame of the machine at one end of which is conveniently secured the
roll B from which the paper to be corrugated is drawn over guiding and tension
rollers and to the corrugating roller C. E E and E2 are suitable rollers of
which there may be any desired number supported by suitable bearings in contact
with the roller C and provided with similar corrugations thereto.
The rollers E E and E' are preferably of different sizes as shown in the drawings.
the first one or two rollers being of comparatively small diameter to draw in the paper.
and give it the set intended. The large roller E2 which with roller C may be kept
highly heated by steam admitted through the pipes ff in the usual manner, serves to
subject the corrugations formed by the first roller or rollers to the proper temperature
and pressure to make them permanent. The small rollers E and E are also preferably
heated by steam admitted through pipes, The corrugating rollers which are in
contact with one another are held together under considerable pressure, those rollers
which are of small diameter in comparison with their length being preferably stiffened.

and supported between their journals by the pressure rollers e e' mounted on the
shafts e, e provided with suitable bearings and adjusting screws e and e. If desired,
however, grooves may be formed in the rollers E E' and stationary pressure bearings
substituted for the rollers e e¹. Curved bands el are also preferably extended partly
around the primary rollers and between this roller and the rollers E E, in which
grooves are formed to allow for the same, in order to prevent any tendency of the
paper to bulge out between the rollers as it passes through the last roller of the series
under which it is not necessary for the bands to extend curing any defects in the
corrugations from the paper passing beneath the grooved portions of the first rollers.
The tank or box F for holding paste or other adhesive substance, is provided with
the roller F extending into the paste in conjunction with a small roller g adapted to
press the superfluous paste off the roller and prevent too large a quantity from
being deposited on the sheet of corrugated paper which as it passes from the
corrugating rollers is held down over the roller F by the small guide rollers g' g².
After the paste has been applied to the corrugated sheet by means of the roller F,
the said sheet is led over the roller G where it is brought in contact with the plain
sheet or backing, and together therewith rolled up upon the roller H.
Beneath the roller G is shown an inking roller and printing roller I together
with guiding and tension rollers K K K² whereby the outer surface of the plain sheet
as it is drawn from the roll L may be printed or impressed before the said sheet is
brought in contact with the corrugated sheet.
By means of the wheels M and N and suitable gearings and connections the
peripheral speed of the pasting roller F is made to correspond with the speed at
which the corrugated paper is drawn from the corrugating rollers so that the convex
edges of the corrugations are simply pressed against the surface of the roller, thus
avoiding the filling of the corrugations with paste scraped from the said roller which
is of no use and furthermore requires extra time for drying. The roller K' is given
such a peripheral velocity that both the fluted and plain sheets move at an even rate
over the roller G. With two or more rollers in contact with the primary corrugating
roller, a greater pressure and heating surface is obtained and deep and permanent
corrugations secured with a rapid motion of the rollers, the capacity of the machino
being largely increased. It is advantageous also to use large rollers in conjunction
with small ones as a series of small rollers alone do not afford sufficient heating
surface and when two or more large rollers are used together in forming deep grooves
or corrugations there is danger of tearing the paper in the process on account of the
resistance offered by the great number of engaging teeth to the free slipping of the
excess of paper required to form the said corrugations. Morcover after a small roller
has been used to draw in the paper and give it the shape intended a large roller may
be effectively employed to add proper finish and permanent set, the teeth of such a
roller being made of a form better adapted to press the paper, as namely thicker at the
base and more tapering than those of the small rollers while the greater available
heating surfaco obtained forms an additional advantage.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents I declare that what I claim is :-
First. The combination of a primary fluted or grooved roller, another fluted or
grooved roller of small diameter in rolling contact therewith and adapted to draw in
the paper and impart thereto the shape intended, and a larger fluted roller also in
rolling contact with the said primary roller arranged and operating substantially as,
and for the purpose, set forth.
Second. The combination of a fluted roller, another Auted roller in rolling contact
therewith and a support acting upon the second roller between the journals and
opposite to the first named roller whereby the said second roller is stiffened and the
pressure exerted thereby increased, substantially as described.
Third. The combination, with a primary fluted roller, of two or more fluted rollers
in rolling contact therewith and curved guiding bands extending partly around the

page_text: said primary roller and between it and one or more of the rollers in contact therewith,
grooves being formed in the last nained rollers to allow for the said bands, substantially
as described.
Fourth. The combination with the corrugating rollers, of the pasting roller so
arranged that its periphery moves at the same rate as the corrugated paper to be
pasted, substantially as and for the purposes, set forth.
Fifth. The combination of a primary flated roller, two or more fluted rollers in
rolling contact therewith, a pasting roller adapted to move at the same peripheral
speed as the corrugated rollers, guiding rollers adapted to bring the strip of paper
fluted by the said corrugated rollers in contact with the said pasting roller, and
driving, and guiding rollers adapted to bring a strip of backing paper against the said
fluted strip, substantially as described.
Sixth. The improved machine constructed substantially as described with reference
to the accompanying drawings and operating as, and for the purposes, above
specified
