PROVEMENTS IN MACHINES FOR ROLLING UP PAPER TISSUES AND OTHER SIMILAR
MATERIALS."
This Invention of improvement in machines for rolling up paper tissues and
other similar materials consists in the following arrangement:-Between two
parallel upright frames, forming a suitable framing, are adapted the following
mechanical agents or parts:-The roll of paper to be operated on, that is, to be
rolled up tightly and regularly on a special axle, is fitted in the lower part of the
machine on an horizontal axle, which turns freely in suitable bearings, and, where
necessary, under a suitable amount of controllable friction. The end of this paper
is led over a horizontal rod, and from thence under a similar rod. The extremities
of these two rods are supported in plates, through the centres of which there runs
a tye rod, which is to be fixed firmly in each side frame. This arrangement forms
a tightener, and by slightly turning the tie rod on its centre the above-mentioned
tightening rollers can be set at different angles, and different degrees of tension
obtained. From this tightener the paper is raised over another roller, and in its
passage to this roller passes in contact with a roller rotating in a contrary direction
to the travel of the paper, for the purpose of smoothing out perfectly the paper as
it passes from this other roller. The paper is fixed to an axle situated below, and
capable of sliding up and down, and supported on a rotating drum. On this axle
are fixed any number of bobbins, on which the paper is to be rolled. This upper
roller, which presses on the axle, is furnished at each end with a groove. The

page_text: distance between these two grooves forms the width of the paper to be rolled up,
and above this upper roller there is an axle carrying two circular sharp edged
knives, suitably geared in connection with the other axle and parts of the machinery,
and in connection with the driving gear. These cutters enter the above-mentioned
grooves, and therefore trin the paper to the required width whilst it is being
rolled up.
Still another roller is placed above those mentioned, and it is provided with any
requisite number of circular cutters, set apart at distances corresponding with the
lengths of the bobbins above mentioned, which cut and divide the paper whilst it is
being rolled up into the widths required. The pressure of this dividing roller, as
well as of the grooved roller, may be conveniently increased by weighting them. It
is by means of this pressure and of the tension on the paper that rolls of paper of
very great hardness can be obtained, particularly adapted for telegraphic and other
purposes. This hardness can be increased or diminished, as required, by weighting
the dividing roller and the following one.
The dividing roller is composed of a metal axle, on which are fixed cast-iron
rings, regulating the width of the bands to be made. Between these rings are
introduced very thin blades of steel, which enter joints of the wooden bobbins on
the winding-up axle. These thin blades of steel remaining in this dividing joint
serve naturally as guides, by which means paper rolls of very great diameter, and
cut perfectly straight, are obtained.
By the application of these thin blades of steel the knives 'may be entirely
dispensed with, except the two outer ones, which regulate the width of paper to be
rolled up.

PROVEMENTS IN MACHINES FOR ROLLING UP PAPER TISSUES AND OTHER SIMILAR
MATERIALS."
A represents an endless roll of paper. The end of the paper is introduced above
the round iron bar B and under another bar B¹ of the stretcher X, which has the
effect of giving a suitable tension. The stretcher X consists of a round bar of iron
fixed by its ends to plates of iron, to which the bars B and B' are equally fixed.
These plates are bolted to the frame of the machine in a suitable position, so that
the tension of the paper is regulated between the bars B and B', according to the
angle it is obliged to follow. From thence the paper passes, gliding against the
roller in cast iron C, which turns inversely, with the object of equalising or smoothing
out the paper perfectly, and so as not to leave any crease or fold in it.. The paper
is then led over the roller in cast iron D, and thence on to the axis E. The roller D
is furnished at its two ends with circular grooves, which are spaced or divided
according to the total width of the bobbins to be inade. Each of these grooves
receives a circular cutter I, destined to cut and regulate the edges of the paper.
These circular knives are driven by a vertical axle M, which is put in action by the
gearing O.
"
The driving of the machine is accomplished by two pulleys, a fast and a loose
one. These serve by means of suitable gearing to put in motion the drum H, on
which rests the axle E. This axle E, which may be reduced to a very small
diameter, is composed of a round bar of iron, on which are fixed the little bobbins
in wood or metal, which have the same width as the paper bobbins it is desired to
have.
When the drum H is put in movement the end of the paper is introduced
between the drum and the axle E. The paper rolls up on the bobbins, which
increase in diameter in proportion as the roller A unrolls. The two rollers in cast
iron, D and G, rest and press directly on the paper which forms the bobbins. It is by
means of this pressure and the tension of the paper that the paper bobbins obtained
are of great hardness, and suitable to many applications. The degree of this hard-
ness is regulated by adding more or less weight to the presser rollers D and G.
The presser roller G is composed of an axle in round iron, on which is fixed cast-
iron rings or segments to form the size of the band required. Between these rings
is introduced a very thin blade of steel 2, having about a centimetre of projection,
and which enters into the joints of the bobbins of the axle E. These steel blades
never coming out of the joint serve naturally as guides, by which bobbins are
obtained of great diameter and cut perfectly straight.
J represents a transverse axle, on which are fixed a fly wheel and two small
pinions gearing with the two racks K, L, which serves to lift up the presser rollers D
and G when the bobbins have attained the required diameter.
The slides P, P', against which the axle E slides are closed in front, enclosing the
axle by the bars Ñ, Ñ', which are casily removed when the bobbins of the axle E
are to be taken away.
In order to obtain always an uniform tension of the paper under treatment the
roll of paper, instead of being supported in bearings secured to the framing of the
machine, may be placed upon two rollers R, S, of cast iron, in the manner shewn in
Figures 1 and 2 on 2nd Sheet of the accompanying Drawing. These rollers carry
at one of their ends the two pinions T, U, gearing into another pinion V, which
causes them to revolve in the same direction. They are further provided each of
them with two adjustable rings, No. 1, 2, 3, 4, fastened by set screws a' distance

page_text: apart from each other, so as to suit the width of the paper roll A, and to keep the
same always in the middle of the machine.
The diameter of the rollers R, S, is so computed that the tension will remain
exactly the same during the whole operation, whether the paper roll be the largest
or reduced to its smallest size. Thus the friction pulleys or any other mechanical
device producing tension are most conveniently replaced by this system, which
moreover offers the great advantage that the machine may be easily supplied with
fresh material, as it is only. necessary to place another roll of paper upon the
rollers R, S, without requiring the use of an axis.
Motion is imparted to the pinions T, U, V, through the intervening gearing Y by
means of the spur wheel W fixed to the axis of the drum H.
Instead of a drum a cylinder of cast iron Z, as shewn in its details in Figures 3
and 4, may be applied if desired. This cylinder is of the same construction as that
of the drying cylinders in paper machinery, and is intended to perfectly dry, calender,
and flatten the paper while being rolled up.
A uniform tension in the width of the paper is obtained through the bearings or
supports No. 5 and 6, of which the latter, No. 6, is stationary, and placed on the
side where the gearings are, while the former, No. 5, is adjustable by means of a small
hand wheel fixed to a screw, and thus permits of the roll of paper being set
obliquely to one side or the other, as may be required, to ensure a uniform tension,
and to prevent the paper from receiving any plaits or creases.
Having now described and particularly set forth the nature of the said Invention,
and the manner of carrying the same into effect, I would have it understood that
what I claim is,-
First. The general arrangement of the machine for the purposes set forth, sub-
stantially as described.
Second. The system of separating the bobbins by means of the thin blades of steel,
substantially as described:
