COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Corrugated
Paper Packing.
I, JOHN SMALLEY, of Trentham Street, Chester Road, Manchester, in the
County of Lancaster, Paper Manufacturer, 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 making packing material for fragile
articles, consisting of a sheet of corrugated paper secured to a sheet of plain paper
or other material, so as to form a fabric capable of affording considerable resistance
to blows, shocks, or pressure..
The invention is designed with the object of providing a machine which will
work more efficiently and more quickly than what are at present employed for this
work.
It will be fully described with reference to the accompanying drawings which
illustrate a machine made in accordance with my invention.
Fig. 1. side elevation.
Fig. 2. plan.
Fig. 3. end elevation.
At one end of a framing A of any suitable construction, I mount the fluted
rollers B which give the required corrugations to one layer of the paper and at the
other end I mount a winding roller C upon which the roll of finished material is
rolled up with an intermediate roller D which revolves in a trough of size, paste or
the like, and over which the corrugated paper passes and receives the mucilage by
which it is made to adhere to the plain layer of paper.
The fluted rollers B are hollow and are heated by a gas flame, passing through
from end to end preferably from a Bunsen-burner 6 placed at one end of each
roller. The products of combustion from the gas in the rollers pass off through the
pipes C.
The roll of paper D' is placed in any convenient place, but the paper passes
therefrom to the inner side of the fluted corrugating rollers B over a series of
guide rods or rollers d, and caused to enter between the rollers at the inner side, so
as to remain in contact with one of them, while half a revolution is made, as by
this means the corrugations are impressed, stiffened and dried into the paper
sufficiently to prevent them expanding or pulling out as the material passes forward
through the machines.
The sizing or gumming roller D rotates in the trough D", and as the material is
drawn over it, the two jockey rollers d', lie upon the surface of it and hold it
against the roller D.

Between the sizing roller D and the winding roller C I pivot a table E, the outer
end of which is always held up in contact against the periphery of the finished roll
of paper on the roller C by means of a balance weight or weights e or suitable
spring. At the other end of the table E is placed a small roller F over which the
layer of plain paper from the roller G travels and meets the layer of corrugated
paper on top of the table E. The upward pressure of the table E keeps the
gummed side of the corrugated paper against the face of the plain paper, and
exerts sufficient pressure on the roll to cause them to lie flat together until the gum,
paste or other mucilage has dried or set.
The paper is guided from the rolls D' and G by the vertical rollers H, against
which one edge of the rolls of paper rest. The bearings of the said rolls may be
set slightly lower at one end than the other to give a gentle inclination and cause
the roll always to bear with its edge against the roller H, or the roll may be placed
evel and the edge pressed against the guide roller H by a spring.

page_text: The fluted rolls are driven from the strap pulleys I through the worm I¹ and
pinions and the winding roll C by the cone drums J J' through the worm ; and
pinions, so that as the amount of material on the roll C and the diameter increases,
the roller shall revolve proportionately slower. The strap K on the cone drums J J1
is moved gradually along by a rack L attached to the strap fork which is moved
slowly along by the wheel L' of the train of wheels l.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
A machine or apparatus for the manufacture of corrugated paper packing
having the several parts constructed and arranged substantially as described and
shown.
