Improvements in the Manufacture of Corrugated Material for Packing
Purposes, and in Machinery therefor.
I, ALFRED GEORGE SPEIGHT, of 257 Liverpool Road, Islington, in the County
of Middlesex, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the manufacture of corrugated material.
for packing purposes, and in machinery therefor, whereby the adhesive medium,
used for affixing the backing or lining material, is applied only to the crowns of the
the corrugations, instead of to the whole surface of the lining or backing material,
as heretofore; and the backing material is delivered or brought into contact with
the corrugated material in a dry condition, thus permitting a considerable saving in
the cost of production.
In carrying out my invention I take a continuous roll or web of paper, or other
like textile fabric, and lead the same between a pair of heated corrugated or fluted
rollers, as is usual in the manufacture of, corrugated packing material. I then pass
it over a roller, or rollers, or over an endless apron, revolving in a trough containing
any suitable adhesive medium, whereby the crowns only of the corrugations or
flutings are supplied with the adhesive medium, slight pressure being applied to the
corrugated or fluted material by an idle roller so as to ensure the application of the
adhesive material to each one of the crowns. The fluted material is then passed
under an idle roller in such a manner as to further ensure that several of the crowns
of the corrugations or flutings shall be in contact with the cementing roller or apron.
It is then carried onto a pivotted table or flap where it meets the backing or lining
material, and is caused to adhere thereto, and which, in my process, is in a dry
condition, and may consist of a light paper of inferior quality. The fluted material,
together with its backing or lining, is then wound upon a winding-on roller. The
pivotted table or flap before mentioned is caused to bear with an equal pressure
against the material being wound up as the roll increases in size, by a weight
suspended from a cord passing over a pulley. Motion is imparted to the winding-on
roller by means of a belt passed around pulleys, one carried by the spindle of the
winding-on roller, and the other by the roller revolving in the trough containing
the adhesive medium. Suitable means are provided for causing the winding
roller to take up the corrugated material at the same rate of speed as it comes from
the corrugating rollers, notwithstanding gradual increase in diameter of the winding-
on roller. These means may consist, in one arrangement, of a pivotted lever, one
end of which is bent up so as to form a shoe or skid for bearing against the pulley
on the winding-on roller, while its other end is acted upon by one of the gear
wheels furnished for the purpose with bosses or projections. Or according to
another arrangement I may employ a rod or spindle which is screw threaded and on
which works a rubber boss or ring so that as the winding on roller revolves this boss
or ring is screwed up or down upon the rod or spindle, by frictional contact with a
disc carried by the winding-on roller.

After the roll of corrugated packing material is completed it is taken off its roller
and allowed to dry.
The machine can also be used for applying, in like manner, a facing, as well as a
backing, to the corrugated material. For this purpose I take the finished roll,

Improvements in the Manufacture of Corrugated Material-for-Packing
Purposes, and in Machinery therefor.
I, ALFRED GEORGE SPEIGHT, of 257 Liverpool Road, Islington, in the County
of Middlesex, Manufacturer, do hereby declare the nature of this invention and' in
what manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say:-
My invention relates to improvements in the manufacture of corrugated' material
for packing purposes, and in machinery therefor, whereby the adhesive medium,
used for affixing the backing or lining material, is applied only to the tips or crowns
of the upper or lower corrugations or flutings instead of to the whole surface of
the lining or backing material, as formerly; and the backing material is delivered'
or brought into contact with the corrugated material in a dry condition. Thus P
am enabled to use-less adhesive medium and thinner backing or lining material
thereby, effecting a considerable saving in the cost of production.
In carrying out my invention I take a continuous roll or web of paper, or other
-like-textile-fabric, and lead the same between a pair of heated corrugated or fluted*
rollers, as is usual in the manufacture of corrugated packing material! I then pass'
it over a roller, or rollers, or over an endless apron, revolving in a trough containing
any suitable adhesive medium, whereby the tips or crowns only of the lower
corrugations or flutings are supplied with the adhesive medium; slight pressure
being applied to the corrugated or fluted material by an idle roller so as to ensure
the application_of_the_adhesive material_to_each_one of the crowns. The fluted'
material is previously passed under an idle roller so as to cause several of the
crowns of the corrugations or flutings, to come into contact with the cementing
roller, or apron, at the same time. It is then carried onto a hinged or pivotted tablo-
which may be furnished with flaps where it meets the backing or lining material,
and is caused to adhere thereto. This backing or lining material' is in my process
in a dry condition, and may consist of a light paper of inferior quality. The fluted
material, together with its backing or lining, is then wound upon a winding,on'
roller.. The hinged or pivotted table, before mentioned, is caused to bear with an
equal pressure against the material being wound up as the roll increases in size, by
weights suspended from cords passing over pulleys: Motion is imparted to the
winding on roller by means of a belt passed around pulleys, one carried by the
spindle of the winding-on roller by means of a belt passed around pulleys, one
carried by the spindle of the winding-on roller, and the other by the spindle of the
roller revolving in the trough containing the adhesive medium. Suitable means
may be provided for causing the winding-on roller to roll up the corrugated material'
without straining or tearing it, as it comes from the corrugating rollers, notwith-
standing the gradual increase in diameter of the winding-on roller. These means
may consist, in one arrangement, of a pivotted lever one end of which is bent up so
as to form a shoe or skid for bearing against a pulley, on the winding-on roller, while
its other end. may be acted upon by one of the gear wheels furnished, for the purpose,,
with bosses or projections.
After the roll of corrugated packing material is completed' it is taken off it's roller
and allowed to dry.

page_text: The machine can also be used for applying, in like manner, a facing, as well as.a
backing. to the corrugated material. For this purpose I take the finished, roll, above
mentioned, and place it upon a roller, situated in front of the machine, and I then
lead the end of the same over an idle roller located above the corrugating or fluting
rollers and pass it direct to the cementing roller or apron, the facing material being
then applied in like manner to that previously described with reference to the
backing or lining material.
And in order that my said invention may be readily understood, I will proceed
to describe the same fully with reference to the accompanying drawings.
Fig. 1 is a side elevation and Fig. 2 is a plan of a machine constructed in
accordance with my invention.
o. is the continuous roll or web of material which is led over the roller band guide
plate c to the pair of heated corrugated rollers d, d', and is corrugated or fluted
thereby. These corrugating rollers receive their motion from a toothed wheel
(Fig. 2) carried by the lower roller d', and gearing with the pinion d³ mounted on
the axis of the fast and loose pulleys d', d, and said corrugating rollers can be
caused to bear against each other with more or less pressure by shifting the weight, de
nearer to or further from the end of the pivotted lever d'.
The corrugated material, as it comes from the corrugating rollers, passes, first
under the roller e and then between the rollers and g, the latter of which is the
cementing roller. This cementing roller is situated within a trough h containing
the cement, or other adhesive medium, and is caused to revolve therein by means of
the toothed wheels ³, do, do, and by its revolution applies the adhesive medium to the
tips or crowns of the lower corrugations or flutings. The roller does not lie
in contact with the cementing roller except at its ends where it is furnished with
flanges so that a space is thus left between these two rollers through which
the corrugated material passes without injury to the corrugations but is yet kept
against the cementing roller with sufficient pressure to ensure the application of the
adhesive medium thereto. The roller e presses lightly upon the corrugated material
by its own weight and is so situated as to cause several of the tips or crowns of the
corrugations to come simultaneously into contact with the cementing roller, which
would not be possible if the roller only were employed. I thereby obtain a more
equal distribution and effectual application of the adhesive medium.
As the corrugated material issues from between the rollers and it passes over
another roller., or wiper, which revolves in contact with the cementing roller, and
any surplus adhesive medium which may be left upon the corrugations is removed
thereby and returned to the trough.
The corrugating material, which is now in condition to receive the dry backing or
lining material is next led over the roller ; where it meets and adheres to the said
backing or lining & coming from the roll k', and the corrugated material, together
with this backing or lining, passes along the hinged or pivotted table, 1, 4, and is
finally wound upon the winding-on roller m. A short length of the finished material
is shewn on an enlarged scale at Fig. 3, where a* are the lower tips of the corrugated
material to which the adhesive medium is applied, and is the lining or backing.
The hinged or pivotted table is in two portions, the one is fixed to the framework
of the machine, and the other is hinged or pivotted at to the fixed portion !
and is caused to bear with a constant upward pressure against the material wound
upon the winding-on roller-notwithstanding the gradual increase in diameter of
this roll as the winding on of the finished material proceeds-by means of
the weights suspended by cords which pass over pulleys & mounted ir.
bearings carried by the side framing of the machine and are connected to the
hinged table at . Thus as the roll of finished material increases in diameter,
the hinged table turns about its hinges and becomes gradually depressed, but
always bears against the roll and ensures that the material shall be evenly and
sufficiently tightly wound thereon, without any risk of its becoming unwound when
the revolution of the winding on roller is stopped. The hinged or pirotted table is

page_text: also provided with hinged side flaps 1x shown more clearly by Fig. 4 which is a
cross section on the line A, A, of Fig. 2. These flaps when turned down into the
position shown in the drawings constitute guide ways for the corrugated material
and prevent any cockling or buckling thercof from interfering with the smooth
winding on of the finished material upon the winding-on roller, and also to keep the
corrugated material in contact with the backing or lining material as it passes on its
way to the winding-on roller.
Motion is imparted to the winding on roller by means of the belt n and pulleys o
and p, the pulley o being driven by the toothed wheel o' which gears with the
wheel do. In order to enable the attendant to control the winding-on of the
finished material a shifting fork is provided so as to permit of the shifting of
the belt from the fast pulley p to the loose pulley p' carried on the axis of the
winding on roller. By this means the attendant can readily stop the revolution of
the winding-on roller when the material has any tendency to become stretched.
The-stopping of the revolution of the winding-on roller does not affect the revolution
of the other rollers and consequently the corrugated material still continues to be
delivered by the corrugating rollers and collects and sags in the space between the
rollers and j. When a sufficient quantity has collected the winding-on roller is
again set in motion by shifting the fork and the winding on roller takes up this
quantity of material without stretching it.

To permit of the roll of finished material being quickly removed from the
machine, I provide one end of the winding-on roller with a square hole into which
enters the square end of the axis p* carrying the fast and loose pulleys p, p'; while
in the other end of the roller is a recess for the reception of the pointed end of a
screw 7. This screw is carried in a bearing and is furnished with a hand-
wheel so that when the winding on roller is in place it is firmly supported at
its ends and can be at once removed by turning the hand wheel, so as to withdraw
the screw r.,
The trough is furnished with eyes or sleeves which fit onto and are capable
of sliding upon guide rods 1ª carried by the bar h³. When it is required to
replenish the trough with the adhesive medium, the rod, which extends below
the trough and supports it in its elevated position, is removed, and the trough can
then be lowered into the position indicated by the dotted lines in Fig. 1, and will
rest upon the bar
Or if it is found inconvenient to shift the trough in the manner above explained,
the trough may be situated near to or upon the ground, and the adhesive-medium-
be conveyed therefrom to the cementing roller by means of an endless band passing
over the cementing roller-and-another-roller-revolving-within-the-trough..
Likewise, if preferable, there may be employed two or more cementing rollers
within the trough instead of one, but I have found that one is in most cases more
advantageous.
I may also, if desirable, apply the adhesive medium to the upper tips or crowns
of the corrugations instead of to the lower ones. In such case the trough would
be arranged above the corrugated material, and a roller revolving in an opening
formed in the bottom of the trough may be employed for applying the adhesive
medium. Or an endless band passed around two or more rollers may be equally
well employed for conveying and applying the adhesive material to the corrugated
fabric.
The endless roll or web of lining of facing material would then be situated above
the machine and be so arranged as to deliver the said lining or facing material upon
the surface of the corrugations. The winding-on roller, upon which the finished
material is to be wound, would, in this modification or arrangement, be caused to
revolve in the reverse direction to that in which it revolves when the lining or
backing is applied to the lower tips or crowns of the corrugations, as in the
previous arrangement. The shifting fork, or the shoe or skid, would also be
arranged accordingly,

page_text: 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 :-
1. Applying the adhesive medium to the tips or crowns of the upper or lower
corrugations or flutings instead of to the backing, lining or facing material, sub-
stantially as and for the purposes described.
2. The use and application of a backing, lining, or facing material in a dry
condition, thus enabling a thinner paper to be employed than heretofore.
3. The manufacture and use of a packing material having its backing or lining,
or its facing, or both its backing and facing, applied in a dry condition to the
previously cemented crowns of the corrugations or flutings, substantially as
described.
4. In a machine for manufacturing corrugated material for packing purposes, and
for applying a dry backing, lining, or facing thereto, the use of a suitably controlled
pivotted table for the purpose of pressing against the finished material as it is wound
onto the winding-on roller, and which table is provided with flaps for guiding the
finished material and preventing cockling or buckling thereof.
5. The improved machine for the manufacture of corrugated packing material,
having its parts combined, arranged, and operating substantially as described and
shown with reference to the accompanying drawings.
