EDWARD EDWARDS COLLEY, of 62, Doddington Grove, Kennington Park, in the
County of Surrey. "IMPROVEMENTS IN APPARATUS FOR WINDING, UNWINDING,
AND CUTTING PAPER FOR PRINTING AND OTHER PURPOSES."
This Invention has for its object improvements in apparatus for winding, un-
winding, and cutting paper for printing and other purposes.
In order to cut paper into continuous strips of any required width I employ
circular knives or cutters mounted on an axis which is rotated, and the cutters
are brought into contact with the paper as the same is being wound into a
roll.
The cutters acting against the surface of the roll, the apparatus I employ is
arranged as follows:-After the paper is wound up into a roll the roll is placed
on a spindle which is mounted in two bearings fitted with friction rollers and
levers weighted so as to regulate the tension and to prevent the paper from un-
winding too freely. The paper is drawn from the roll and is then passed through
two pair of circular shears to trim the rough edges of the paper.
It then passes in
two horizontal cylinders, which are finely fluted from end to end of each cylinder,
and which are driven by a tooth wheel geared into wheels fixed on the ends of
the cylinder spindles. The centre wheel is given motion to in the usual way by
fast and loose pulleys. A roller or spool rests on the horizontal grooved cylinders,
and is rotated by them at a constant surface speed. The paper is wound upon the
roller or spool, and whilst this increases in bulk from the accumulation of the paper
around it the ends of the roller spindle rise up vertical guides in the side frames.
The spindle is pressed down by two side levers supplied with moveable weights to
regulate the tension of the paper..
The cutting frame consists of arms carrying an axis on which the circular knives
are fixed at the required distances apart, and the axis also carries two loose rollers,

and it can at pleasure be brought down so that the edges of the cutters come
into contact with the roll. This position it occupies when the machine is at
work.
The loose rollers, one at each end of the axis, rest on the roll, and supporting the
spindle. The rollers regulate the depth to which the cutters penetrate, the cutters
being somewhat larger than the rollers. The rollers have flanges on their edges
which overlap the sides of the roll and aid in guiding the cutter frame, so that
each strip may be cut truly of the width required. Thus the paper is cut at the
same time as it is being wound upon the spools.
I sometimes use straight or curved knives in a fixed bar in place of rotating
knives, but I prefer the circular revolving cutters.
By these arrangements I can cut any number of various or similar widths by
one operation from the one roll of paper.
In place of unwinding the paper from a roll it may be passed direct from the
paper making machine to the cutting apparatus.

This Invention has for its object improvements in apparatus for winding,
unwinding, and cutting paper for printing and other purposes.
In order to cut paper into continuous strips of any required width I employ
circular knives or cutters mounted on an axis which is rotated, and the cutters are
brought into contact with the paper as the same is being wound into a roll, the
cutters acting against the surface of the roll.
The apparatus I employ is arranged as follows:-After the paper is wound up
into a roll the roll is placed on a spindle, which is mounted in two bearings fitted
with friction rollers and levers weighted so as to regulate the tension and to
prevent the paper from unwinding too freely. The paper is drawn from the roll,
and is then passed through two pairs of circular shears to trim the rough edges of
the paper, it then passes to two horizontal cylinders which are finely fluted from
end to end, and which are driven by a toothed wheel geared into wheels fixed on
the ends of the cylinder spindles. The centre wheel is given motion to in the
usual way by fast and loose pulleys; a roller or spool rests on the horizontal
grooved cylinders, and is rotated by them at a constant surface speed. The paper
is wound upon the roller or spool, and whilst this increases in bulk from the
accumulation of the paper around it the ends of the roller spindle rise up vertical
guides in the side frames. The spindle is pressed down by two side levers supplied
with moveable weights to regulate the tension of the paper.
The cutting frame consists of arms carrying an axis on which the circular knives
are fixed at the required distances apart, and the axis also carries two loose rollers,
one at each end. The axis is driven at a considerable velocity, and it can at
pleasure be brought down so that the edges of the cutters come into contact with
the roll. This position it occupies when the machine is at work.
The loose rollers, one at each end of the axis, rest on the roll, and supporting the
spindle they regulate the depth to which the cutters penetrate, the cutters being
somewhat larger than the rollers. The rollers have flanges on their edges which
overlap the sides of the roll and aid in guiding the cutter frame, so that each strip
may be cut truly of the width required. Thus the paper is cut at the same time
as it is being wound upon the spools.

By these arrangements I can cut any number of various or similar widths by
one operation from the one roll of paper.

Having thus described the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view; Figure 2 a front view; and Figure 3 a back view
of machinery constructed according to my Invention for cutting paper into strips
for printing and other purposes.
u is a roll of paper to be divided into strips, it is mounted on a spindle b, to
which friction is applied by a weighted lever c, as shewn, or otherwise to regulate
the tension and prevent the paper unwinding too freely. d, d, are two pairs of
circular shears to trim off the rough edges of the paper and bring it to a uniform
width; for many purposes these shears may be omitted. c is the roller, by preference
a wooden roller, on to which the paper is wound, it rests on two fluted rollers, f, f,
and as paper is wound on to it it can rise in vertical guides in the framing of the
machine, as shewn. The ends of the spindle are pressed downwards by weighted
levers, as shewn. The two fluted rollers are driven on the opposite side of the
machine to that shewn at Figure 1 by a central toothed wheel gearing into toothed
wheels on their ends. The central wheel is driven by fast and loose pulleys, as shewn
at Figure 3. is an axis, having mounted upon it a series of disc knives /, kept at
the required distance apart upon the axis by filling discs of any desired width,
according to the width of strips into which the paper is to be cut, the knives and
filling pieces are held fast on the axis by a nut at one end of the axis. pressing
them up to a collar at the opposite end. The axis is carried at its ends by arms
m, which at their opposite ends can turn around the axis n.
Motion is given
continuously from the axis n to the axis g by bevil-toothed wheels and inclined
shaft o.
The axis is itself driven by toothed wheels from one of the fluted
rollers, as shewn at Figure 1. The circular shears d are driven from the other
fluted roller by bevil wheels and shaft p. By preference I drive the axis g which
carries the knives in such a direction that the knives where they bear upon the roll
are travelling in the same direction as the roll and cause the knives to revolve at
about twice the surface speed of the roll.
By the arrangement of machinery above described the paper as it is wound up into
a roll on to the roller e is divided up into strips, and when a length of paper has
thus been wound into a roll and divided the roller e may be withdrawn from the
roll. The several strips into which the paper has been divided are thus obtained
each in a separate coil or roll, as when the spindle is withdrawn they all separate
the one from the other.
Having thus described the nature of iny Invention and the manner of performing
the same, I would have it understood that I claim-
First. The combined arrangement of apparatus substantially as herein described
for cutting paper into strips.
.
Second. The employment of a series of knives bearing continuously on a roll on
to which paper is being wound to divide such paper into strips substantially as
described.
In witness whereof, I, the said Edward Edwards Colley, have hereunto set my
hand and seal, this Twentieth day of October, in the year of our Lord
One thousand eight hundred and seventy-six.
