I. JAMES EVANS, of 31, Bramley Street, Manchester Road, Bradford, in the County
of York, Mechanic, do hereby declare the nature of this invention to be as follows:-
This invention relates to machinery or apparatus for cutting and making conical
paper or similar tubes for holding yarn.
The said invention consists of the devices and arrangements of mechanism herein-
after described whereby the paper is cut to the required shape and formed into tubes.
I will describe my improved cutting and tube making apparatus as comprising one
machine but independent machines may be employed.
Between suitable frames preferably consisting of standards and bed plate two
cutting rollers are mounted geared together and provided with driving mechanism.
Two or more waved or serpentine parallel cutting edges project from the periphery
of one of the said rollers and corresponding grooves or depressions are formed in
the other roller thus when a strip of paper is passed between the said rollers the
edges are cut to a waved or serpentine form and if more than two cutting edges
are used a sheet of paper may be cut into a waved or serpentine strips.
A convenient method of constructing the cutting rollers consists in forming a
serpentine groove in one roller the width and contour of the strip required to be cut
and a corresponding projection is formed on the other roller thus the edges of such
groove and projection shear the paper as it passes between them.
At a suitable distance from the cutting rollers and preferably connected thereto by
gearing a pair of perforated rollers are placed. The periphery of one of the perforated
rollers is provided with rows of pins punches or teeth lying at an angle with the
axis of the said roller each row being parallel with the next but one and at an angle
with those next to it. The other roller is adapted to press the paper passing between
them against the said rows of pins punches or teeth so as to perforate it without
damaging them.
The said perforating rollers are so relatively placed and arranged with the cutting
rollers that the said strip or strips of paper passing between them is or are perforated

page_text: -
so as to readily tear off into pieces of the size required to make the conical tubes, that
is, with the perforated ends at an angle to each other, and a concave curve at one side
and a convex curve at the other.
The cutting and perforating operations may be performed by one set of rollers and
it is obvious that if required the paper may be cut off instead of being perforated.
The strips of paper after being perforated pass between two endless bands of india-
rubber or other suitable material mounted on suitable rollers and are carried towards
two revolving taper spindles inclined at an angle to each other and to the said endless
bands. The rollers feeding the paper into the endless bands have a greater surface
speed than the perforating rollers and are arranged to have an intermittent nip so as
to separate the perforations and pass the papers separately towards the said taper
spindles before reaching which they are covered with paste or other adhesive substance
in any convenient manner.
From the foregoing description it will be seen that as the papers approach the said
taper spindles they lie with each front perforated edge at an angle with the front
edges of the papers next to them and parallel to the front edge of every alternate
paper therefore the front edges of the papers consecutively lie at an angle to each
other. The axis of the two taper spindles are arranged at these angles and as the
papers come in contact with such spindles they are twisted round and formed
into tubes.
As soon as the tubes are complete the endless band is moved from contact from
them, preferably by the same motion regulating the above mentioned intermittent
nip, and they are pushed or drawn off the spindle by suitable fingers operated by
cams or other means.
The various motions of the parts are so relatively arranged that during the time the
tubes are being removed from the spindles, and the endless band is not in contact
therewith, the next papers to those last operated upon pass beneath clear of the first
spindle and thus reaches the second spindle which is inclined at the same angle as
the advancing edge of the paper. By this arrangement each, spindle rolls every
alternate paper.

I, JAMES EVANS, of 31 Bramley Street, Manchester Road, Bradford, in the County
of York, Mechanic, 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 machinery or apparatus for cutting and making conica¹
paper or similar tubes for holding yarn.
The said invention consists of devices and arrangements of mechanism hereinafter
described whereby the paper is cut to the required shape and formed into tubes.
I will describe my improved cutting and tube making apparatus as comprising one
machine but independent machines may be employed.
Between suitable frames preferably consisting of standards and bed plate two cutting
rollers are mounted geared together and provided with driving mechanism. Two or
more waved or serpentine parallel cutting edges project from the periphery of one of
the said rollers and corresponding grooves or depressions are formed in the other
roller thus when a strip of paper is passed between the said rollers the edges are cut
to a waved or serpentine form and if more than two cutting edges are used a sheet of
paper may be cut into waved or serpentine strips.
At a suitable distance from the cutting rollers and preferably connected thereto by
gearing a pair of perforating rollers are placed. The periphery of one of the per-
forating rollers is provided with rows of pins, punches or teeth lying at an angle with
the axis of the said roller each row being parallel with the next but one and at an
angle with those next to it. The other roller is adapted to press the paper passing
between them against the said rows of pins, punches or teeth so as to perforate it
without damaging them.
The said perforating rollers are so relatively placed and arranged with the cutting
rollers that the said strip or strips of paper passing between them is or are perforated
50 as to readily tear off into pieces of the size required to make the conical tubes, that
is, with the perforated ends at an angle to each other, and a concave curve at one side
and a convex curve at the other.
The strips of paper after being perforated pass between endless bands of india-
rubber or other suitable material mounted on suitable rollers and are carried towards
two revolving taper spindles inclined at an angle to each other and to the said endless
bands. The rollers feeding the paper into the endless bands have a greater surface
speed than the perforating rollers and are arranged to have an intermittent nip so as
to separate the perforations and pass the papers separately towards the said taper
spindles before reaching which they are covered with paste or other adhesive sub-
stance in any convenient manner. From the foregoing description it will be seen
that as the papers approach the said taper spindles they lie with each front perforated
edge at an angle with the front edges of the papers next to them and parallel to the
front edge of every alternate paper therefore the front edges of the papers consecutively
lie at an angle to each other. The axis of the two taper spindles are arranged at

page_text: round and formed into tubes..
As soon as the tubes are complete the endless band is moved from contact from
them, and they are pushed or drawn off the spindle by suitable fingers operated by
cams or other means.
The various motions of the parts are so relatively arranged that during the time
the tubes are being removed for, the, spindles, and the endless band is not in contact
therewith, the next paper to those last operated passes beneath clear of the first
spindle and thus reaches the second spindle which is inclined at the same angle
as the advancing edge of the paper: By this arrangement each spindles rolls every
alternate paper.
To describe my invention more in detail reference is to be had to the accompanying
sheet of drawings forming a part of this specification in which similar letters of
reference indicate corresponding parts in each of the figures.
Figure 1, represents a longitudinal section of my improved machine omitting the
spindles upon which the tubes are formed and the mechanism operating the same.
Figure 2, is a plan view of the same and also including said tube spindles and
mechanism.
Figure 3, is an end elevation of the machine with the tube spindles and the
operating mechanism turned slightly out of their true position in order to represent
them in full.
Figure 4, represents a short length of the paper illustrating the manner in which it
is cut and perforated.
Figure 5, is a side view of the device for pushing the tubes off the spindles and
figure 6, is a plan of the same.
The standards A support the bed plate B, which at the feed end carries the reel
holder C supporting a roll of paper D upon the roller E, and the paper D-passes off
the said roll between the cutting rollers F and G. The said .rollers are geared
together by the wheels H and J to revolve at an equal speed and are mounted in the
standards K secured to the bed plate and the upper roller F is formed with a
serpentine shaped periphery adapted to fit and revolve closely in a similarly shaped
serpentine groove formed in the bottom roller G. As the paper D passes between F
and G the serpentine edges 10 of the upper roller in combination with the similarly
shaped edges 12 of the groove in the lower roller operate as a pair of shears and trim
the edges 13 and 14 of the paper parallel and to the serpentine form shown, the small
rollers L are employed to guide the narrow edges of the paper trimmed off by the
cutting rollers away from the machine.
The serpentine cutting or shearing edges 10 and 12 are preferably formed upon
sleeve pieces mounted upon the cylindrical foundations F and G which enables them
to be readily sharpened and relatively adjusted so that the cutting edges of the upper
roller revolve closely against those of the lower roller.
After being cut the paper D passes between the perforating rollers M and N which
are mounted in the standards O, and are geared together by the wheels P and Q and
are also connected by the intermediate wheel R to the cutting rollers so as to revolve
at the same surface speed. The roller N is.connected to the wheel S on the main
driving shaft I by means of the double stud wheel T and U and the wheel V mounted
on the arbor of the bottom guide roller 19.
The roller M is provided with four rows of perforating pins 15 set in grooves 16
inclined at a suitable angle with the axis of such roller and with each other so as to
perforate the paper passing beneath at intervals in the manner represented by the
dotted lines crossing figure 4. Bolsters 17 of leather or other suitable material are
fitted in grooves 18 in the bottom roller arranged to meet the pins of the top roller
and prevent them being damaged.
The cutting and perforating operations above described may be performed by one
set of rollers by fitting rows of pins at suitable angles and positions in the cutting
rollers, but owing to the ends of such rows interfering with the cutting edges 1 prefer
employing independent rollers.

page_text: The said cutting and perforating rollers may comprise an independent machine
adapted to cut papers to be made up by other machines or by hand, in which case the
pins of the perforating rollers may be replaced by knives constructed to totally divide
the papers. And more than one pair of each of such rollers may be arranged side by
side adapted to divide sheets of paper into serpentine strips, and perforate or livide
them. In this case in order to prevent waste of paper the cutters on the upper rollers
excepting the end ones are preferably formed to a knife edge and a bolster of solt
material is mounted in serpentine grooves in the roller below to protect such knife
edges.
After leaving the perforating rollers the paper D passes between the endless india
rubber bands a and b which have a greater surface speed than such rollers and as soon
as each paper gets fairly beneath the nip roller c the eccentric or proud portion d of
its periphery revolving in contact with the bands b presses such bands against the
band a causing them to nip the paper and draw it in at a greater speed than it is
delivered by the perforating rollers and consequently dividing it at the first perforations
the next paper being still held by the perforating rollers, by this means a little space
is left between the papers as they pass between the bands. The nip roller c is driven
by the wheel X mounted on its arbor engaging the wheel Y fixed on the main
shaft I.
The band a is a continuous band slightly broader than the papers, it passes from
contact with the pasteing roller e beneath the guide rollers 19 and 20 and between
the roller 21 (fixed on the main shaft I) and the roller 19, it then turns up over guide
rollers 22 and 23, and is guided down by the tension roller 24 to the said pasteing
roller which supplies the band with paste from the trough g, preferably heated to a
suitable temperature by being surrounded with a steam jacket h. b is divided into
four or more narrow bands which lie in the grooves 25 formed in the guide roller 26,
the driving roller 21 and the tension roller 28. As the papers pass between the bands
they are thoroughly saturated with paste and the surplus is squeezed off by the
rollers 19 and 21, after which the papers pass up and leaving the bands & are carried
by a towards the tube spindles n and o.
The spindles n-and o project from mandrels j preferably driven from overhead and
carried in adjustable brackets fixed on the table m mounted upon the bed plate. The
top roller 23 is mounted between arms 29 pivoted at 30 upon the arbor of 22 and an
up and down motion is communicated to such roller, thereby raising and lowering the
belt a, by means of the cam 31 supporting the free end of the arms 29 through the
medium of the hangers 32 projecting below said arms and anti-friction rollers 33.
The up and down motion of the belt a is so timed in respect to the feed of the papers
that the first paper is allowed to pass beneath the spindle n to the spindle o, by which
time a second paper has reached in the cams then raise a so as to bring the advancing
edges of such papers in contact with the spindles which revolving at a greater surface
speed than a rapidly wind such papers round them thus forming them into tubes and
by continuing to revolve polish their outer surface against the band. An inclined
roller 34 carried between the arms 29 supports a beneath the spindle n. The spindles n
and o each take every alternate paper and are so inclined that they touch the whole
width of and are parallel with the advancing edges of the papers.
The tubes are knocked off the spindles n and o by means of the fingers or jaws 35
mounted in the radial guides 36. formed in the shells 37. The spindles pass through
the central holes of such shells which have a reciprocating motion imparted to them
along the spindles and the india rubber rings 38 press the said fingers inwards they
therefore closely embrace the spindles the whole of their length and knock off the
finished tubes without damaging them. They have also a tendency to keep the
spindles clean. The said shells are reciprocated by means of the forks 39 projecting
at right angles from the rods 40 sliding in bearings in the top of the brackets l. The
rods and connections 40 are pressed inwards by means of levers 41 pivoted at 42 and
vibrated by the cams 43, engaging antifriction rollers 47 mounted upon pins pro-
jecting at right angles from the lower ends of such levers.

page_text: India rubber springs 44 stretching from the end 45 of each bracket to the top
projection 46 of each fork restore the parts to their former position after the tubes are
removed. In the drawings the spindle o is represented with the rod 40 and shell 37
pushed inwards to the point of the spindle by its lever and cam, and the spindle n is
shown with its shell and connections drawn back by the spring 44.
The cams 31 and 43 are mounted upon the cam shaft 50 driven from the wheel S
on the main shaft by means of the intermediate wheel 51 and the wheel 52 mounted
upon such shaft:
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The general construction and arrangement of conical tube forming mechanism,
in combination with cutting and perforating rollers, substantially as herein shown and
