Improvements.in and connected with the Folding of Paper.
We, ALFRED GEORGE BEALE of Monson Terrace, Tunbridge Wells, England,
Physician & Surgeon and THOMAS NESBITT, 27 Thorndale Avenue, Belfast,
Ireland, Master Mariner 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 which relates to the manufacture of papers such as are used by
chemists for wrapping up powders in will be best understood by reference to the
accompanying drawings, in which
Figure 1 is a sectional side elevation of a machine adapted to carry out this
invention
Figure 2 being a plan thereof.
Figure 3 is a detail on a larger scale of one of the creasing rollers.
Figure 4 represents the first folder in two positions and the paper as turned out.
Figure 5 represents the second folder and its paper and
Figure 6 the third folder and its paper,
Figure 7 being a plan of the creased paper laid out flat and
Figure 8 a plan showing the paper folded.
Like letters represent like parts throughout the drawings.
The object of this invention is to produce powder papers for chemists, or papers
of a similar nature adapted for other similar purposes, creased by machinery and
supplied in detached papers whereby much time is saved in the folding of the
papers after the contents are inserted, while a better result is obtained, as all the
papers are not only uniformly folded but the various lines are parallel and a neater
paper is produced. The machinery or apparatus described in this Specification is
designed for carrying into effect the above invention no machinery existing at the
present time for this purpose.
A represents the bed of the machine which may be of any convenient description
and either of metal or wood. B is a bracket or head stock containing the roll C of
paper or other suitable material carried upon a shaft or spindle C¹ journalled in the
two sides of the bracket or head stock B. This paper is of the same width as the
CD

page_text: ultimate powder paper when unfolded. D is a roller journalled at each end in
the bracket or head stock B but so arranged that by means of the screw D¹, a
spring or other equivalent means, it can be brought to bear with sufficient pressure
upon the strip or band of paper E to produce upon the said paper the required
tension. Fis the first folder, G the second folder and H the third folder, the
details of which will be understood by reference to Figures 4, 5 and 6. The
folder F at its leading end 1 is semicircular as indicated in the view to impart
an easy fold to the paper, but at its back end 2 has a sharp angle as indicated in
the view F to impart the sharp crease required to the paper; these views are upon
a considerably larger scale than the other figures for the sake of clearness but the
size and strength of the folders and the whole apparatus would depend upon the
paper or similar material to be operated upon and the size and strength of
the papers to be creased. The folder F is formed of a piece of thin sheet metal
folded so as to produce at its leading end the semicircular shape indicated in F
where shows a projecting end of the metal folded over so as not to interfere with
the passage of the paper, and f¹ shows the other edge terminating within the semi-
circle. The folder may be secured upon the bed or stand in any convenient manner.
as for example by screws passing through the projecting lip f. E Figure 4 shows
an end view of the paper with the crease or fold E' imparted to it.
From the first folder F the paper passes to the second folder G Figure 5 in
which is produced the second fold E, the doubled portion of the paper E³ E
Figure 4 being in the lower channel of G and the small fold E' Figure 4 being in
the upper channel of the folder as indicated in Figure 5. This folder likewise can
be fastened in any convenient manner as by screws passing through the extension G',
Figure 5. The view of the paper E in Figure 5 will indicate the condition of the
paper so far.
Figure 6 shows the third folder II in which the paper, folded as in Figure 5 but
with the flap E pressed down flat upon the other folds, has its last longitudinal
crease imparted to it. It is entered at the leading end 1, which takes the form
of H Figure 6. The back end 2 of the folder H is folded to a sharp angle as
shown in Figure 6 the paper coming out as shown at E Figure 6, the fold E
Figures 6 and 7 being a double one on account of the paper having been doubled
before this crease is inade.
or creased.
As
From the folder H the paper passes between the india-rubber covered roller I,
Figures 1 and 3, and the wooden or other roller J, which is provided with knives J¹
set longitudinally in the roller; these two rollers are carried in bearings in the
bracket or head stock K secured to the frame work in any convenient manner.
the paper passes between these two rollers they are both revolved and the knife
edges impart the cross creases E7 and E, Figure 7, to the paper, the rubber
yielding to the pressure of the knife so that the paper is not cut but only marked
This is the last of the folding and creasing part of the process, the
subsequent operations of the mechanism relating to the unfolding of the paper in
which the creases or lines remain. L represents the first unfolder which consists as
shown by the enlarged view Figure 9 of a bent wire or staple L' set in or carried
by the supporting bracket or head stock L of any convenient description and
suitably secured to the framing; the paper passes through the space L' and thus
has its first fold taken out, the paper emerging from the unfolder L in the same
condition in which it left the folder G.
From L the paper passes to the second unfolder M similar to L but placed
vertically as it is found convenient to give a partial twist to the paper as it passes
between the unfolders L and M; otherwise the construction of M is similar to that
of L, the paper passing through the space M² between the bracket or head stock M
and the wire, staple or equivalent M.
The third unfolder N is similar to the first one L but is for convenience made
rather higher (if the rollers at the end of the apparatus require it) and as the
paper passes through it the last fold has been taken out and it leaves the
unfolder N flattened out and of its full width as when it was on the roll C at

page_text: the commencement of the operation but bearing all the longitudinal and cross
creases.
From the last unfolder N the paper passes between the drawing rollers O P
journalled in the bracket or head stock Q secured upon the bed and which rollers
draw the paper through the whole of the folding, and unfolding apparatus and to
one or both of which motion may be imparted by belts or gearing in any convenient
manner. After passing the rollers O P the paper is delivered to the fixed cutter R
between which and the revolving cutters S it is nipped and cut off in the required
lengths. The revolving cutters S are carried upon a suitable shaft. S' journalled in
the bracket or head stock Q or in an independent bracket or head stock and driven
at a suitable speed preferably by means of gearing connecting the spindle S with
the spindle P of the roller P the relation between the rollers O P and the revolving
knife or cutter S being such that the length of paper passing over the knife R
between the nip of one cutter S and the nip of the next cutter S will be the exact
length of the powder paper required. The papers as they drop from the cutters R
and S fall into any suitable receptacle or onto a travelling band and may be
collected, counted and placed in bundles or boxes for sale in quantities as required,
each individual paper being marked or creased as in Figure 7 and adapted to be
folded as in Figure 8 when required for use.
In starting this machine the paper will be in the first instance folded and placed
in the folders carried between the resilient and knife edge rollers, and unfolded and
placed in the unfolders and carried between the drawing rollers and placed in
position over the fixed separating knife all by hand after which the operation of the
machine is entirely automatic until the roll of paper is consumed when a fresh roll
will be supplied and may either be again entered by hand or may be efficiently
secured to the end of the previous strip so that it will be automatically drawn into
the machine.
As it is sometimes desirable that the paper should bear a printed description of
the contents, or for other reasons should bear printed matter upon them, this may
be done by printing upon the paper before it is rolled up, and at suitable intervals
and at the right place in the width of the paper and of a proper size to suit the
unfolded portion of the paper any matter that it is desired to place upon the
finished papers.
The intervals would be such as to coincide with the size of
the respective papers when cut and when the printing is adopted care must be taken
when first introducing the strip into the machine to place the printed matter in
such relation to the knives for separating the papers from the strip that the letter-
press will come in the longitudinal centre of each paper. For advertisement
purposes the papers could be printed all over and on one or both sides, but usually
the object of the printing would be merely for the purpose of indicating the nature
of the contents of the folded paper.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A paper adapted to contain chemists' powders and the like and bearing the
lines or creases upon which it is to be folded substantially as described.
2. The method of facilitating and regulating the folding of powder and similar
papers which consists in imparting to the paper before it is used the necessary folds
or creases substantially as described.
3. In a paper folding and creasing machine the combination in the same machine
of the roll of paper or other material the folders which impart the longitudinal
folds and creases the cross-crease rollers which impart the cross creases and the
unfolders which open the strip out again substantially as described.
4. In a paper folding and creasing machine the combination with the folders such
as F G H which impart the longitudinal folds and creases and the cross-crease
rollers such as I and J which impart the cross creases of the unfolders such

page_text: as L M N which unfold the strip substantially as described and illustrated in the
accompanying drawings.
5. In a paper folding and creasing machine the combination with the roll of
material and the folding creasing and unfolding devices of separating knives such
as R and S so timed or adjusted as to cut off the required lengths from the strip as
it is delivered to them substantially as described.
6. In a paper folding and creasing machine the combination with the drawing
rollers such as O and P positively driven at a predetermined speed of the revolving
knives such as S so timed or regulated as to operate in conjunction with the said
drawing rollers to separate from the strip the predetermined lengths substantially
as described and illustrated in the accompanying drawings.
7. The combination and arrangement of parts constituting the complete folding
creasing unfolding and separating machine substantially as described and illustrated
in the accompanying drawings.
