We, WALTER ETHARD Goss, and JOHN Goss, both of High Street, Kettering, in
the County of Northampton, Printers, Stationers, Bookbinders, and Box Makers,
do hereby declare the nature of this invention to be as follows:-
Our invention relates to machines for slitting paper webs into strips or bands,
and has for its object to provide a machine which is simpler in construction and
cheaper to manufacture than machines of the class as heretofore constructed.
In constructing a machine according to our invention, we provide a suitable
frame having bearings for the shafts or spindles for carrying the roll of paper
web to be slit and the tubes onto which the bands or strips are wound, the last
mentioned shaft or spindle which is hereinafter referred to as the receiving spindle
being adapted to be rotated by any suitable means. This receiving spindle is
also provided with a series of teeth adapted to be projected from the periphery
of the said receiving spindle in order to grip or hold the tubes upon which the
strips or bands are wound against rotation relatively with the said receiving
spindle.
In practice the receiving spindle may be made hollow and have a second spindle
within it to which the teeth which project through openings in the outer spindle
are pivoted in such a manner that when one spindle is rotated relatively with the
other the said teeth will be projected or vice versa.
Between the spindle upon which the roll of web is mounted and which I term
the store roll spindle and the receiving spindle is a shaft hereinafter termed the
cutter shaft carrying a series of knives or slitting cutters, which cutter shaft is
adapted to be turned upon its axis in order to bring the cutters into the path of
the paper web which passes between or around suitable guide rollers.
Beneath or adjacent to this cutter shaft is a brush or its equivalent which is
also adapted to be moved into or out of contact with the paper. This brush serves
for holding the paper web with a flexible pressure against the knives, and con-
stitutes an important feature of our invention.
It is to be understood that the knives or slitting cutters are adjustable upon the
cutter shaft in order to permit of altering them to vary the widths of the strips or
bands being slit.

We, WALTER ETHARD GOSS and JOHN Goss, both of High Street, Kettering, in
the County of Northampton, Printers, Stationers, Bookbinders and Box Makers,
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:
Our invention relates to machines for slitting paper webs into strips or bands,
and has for its object to provide a machine which is simpler in construction and
cheaper to manufacture than machines of the class as heretofore constructed.
In constructing a machine according to our invention, we provide a suitable
frame having bearings for the shafts or spindles for carrying the roll of paper web
to be slit and the tubes onto which the bands or strips are wound, the last
mentioned shaft or spindle which is hereinafter referred to as the receiving spindle
being adapted to be rotated by any suitable means. This receiving spindle is
also provided with a series of teeth adapted to be projected from its periphery in
order to cause the tubes upon which the strips or bands are wound to rotate with
the said receiving spindle.
In practice the receiving spindle may be made hollow and have a second spindle
within it to which the teeth which project through openings in the outer spindle
are pivoted in such a manner that when one spindle is rotated in one direction
relatively with the other the said teeth will be projected and vice versa.
Between the spindle upon which the roll of web is mounted and which we term
the store roll spindle and the receiving spindle is a shaft hereinafter termed the
cutter shaft carrying a series of knives or slitting cutters, which cutter shaft is
adapted to be turned upon its axis in order to bring the cutters into the path of
the paper web which passes between or around suitable guide rollers.
Beneath or adjacent to this cutter shaft is a brush or its equivalent which is
also adapted to be moved into or out of contact with the paper. This brush serves
for holding the paper web with a flexible pressure against the knives, and consti-
tutes an important feature of our invention.
It is to be understood that the knives or slitting cutters are adjustable upon
the cutter shaft in order to permit of altering them so as to obtain different widths
of strips or bands.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a front elevation of our improved paper slitting machine:
Figure 2 is a sectional side elevation of the same; and,
Figure 3 is
plan:
Figure 4 is a plan of a portion of the receiving spindle drawn to a larger scale
than Figures 1 to 3; and,
Figure 5 is a section of the same on the line 5-5 Figure 4.
Figure 6 is an elevation illustrating a slight modification.
a, a are two standards of the framing the said standards as shewn being braced
together by the tie-bar 6 the tie frame c and the stretcher & which forms the bed
or table of the machine.
°
e is the spindle for carrying the roll of paper web (indicated by the dot-and-
dash circle fin Figure 2) to be slit and is the receiving spindle on to which the
paper is wound after being slit, the said spindle g being carried in bearings formed
in arms h, h projecting from the side frames or standards a, a.
the spindle e are formed in two brackets i, i cast upon the frame standards a, a and
The bearings for
each of the brackets is provided with a clamping piece j operated by a set screw j¹

page_text: to permit of applying more or less friction to the spindle e to prevent the roll
revolving too rapidly.
k is the spindle which is fitted within the receiving spindle 9 which is tubular
and 1,1 are the teeth designed to be projected beyond the peripheral surface of the
spindle g in order to engage with the paper tubes which are placed upon the said
spindle and upon which the strips of paper formed by the slitting are wound, the
said teeth being adapted when the receiving spindle is turned in one direction
to project beyond the peripheral surface of the spindle g, as shewn in Figure 5,
and when it is rotated in the reverse direction to be withdrawn within the said
spindle.
As shewn in the drawings the teeth 1 are represented as being arranged in the
following manner, that is to say, each tooth is provided at its rear end with a
hole m designed to engage on a pin n on the spindle & the other or free end of each
tooth projecting through a corresponding hole in the tubular receiving spindle g.
In placing these teeth in position they are introduced into the receiving spindle g
before the spindle k is applied the free ends of the said teeth being passed through
the holes formed in the said receiving spindle. The spindle k, which is of con-
siderably smaller diameter than the bore of the tubular spindle g, is then intro-
duced within the said receiving spindle g and the pins n, n introduced into the
holes in the rear ends of the teeth m, m when collars o, o (one of which is shown
in Figure 4) are passed over the ends of the spindle k and introduced into the
spindle g in order to retain the said two spindles in their proper relative positions.
The rotary motion of the spindle & relatively with the receiving spindle g causes
the teeth to be projected from or drawn within the said receiving spindle, the
amount of this relative movement being regulated by means of a pin p fixed upon
the spindle and working in a notch 7 formed in the collar o at one end of the
receiving spindle as clearly shewn in Figure 4.
With this arrangement it will be understood that when the hand wheel r fixed
to the end of the spindle is rotated in the direction of the arrow 1 Figure 2, it
will, assuming the teeth are within the receiving spindle g, project the said
teeth to engage with paper tubes previously placed upon the said spindle and
cause the same to rotate with the receiving spindle, and that when the said hand
wheel is rotated in the reverse direction the teeth will be drawn within the
receiving spindle g out of engagement with the said paper tubes so that the latter
can be removed from the spindle.
The paper in its passage from the store roller f, to the receiving spindle 9
passes over the guide roller s, the top of the stretcher d and under the guide roller s³,
the latter roller being carried in bearings on the stretcher d while the roller s is
carried in arms s2, s2 adjustably secured to the said stretcher.
t is the cutter shaft which is also carried at the ends in bearings on the stretcher d
the said shaft having upon it one or a series of knives or cutters u, u arranged
to project in a radial or approximately radial direction from the said shaft. As
shewn in the drawing the several knives u, u are carried by sleeves or blocks v, v
which are made adjustable upon the shaft t to permit of adjusting the position of
the knives according to the width of the strips into which the paper web is to be
cut.
The position of the spindle t is such relatively with the guide rollers s, s¹ that
the knives can be moved to project into the path of the paper as indicated in
Figure 2 or turned back so as to be out of the path of the paper. w is a lever
fixed to the end of the shaft t and serving for rotating the said shaft to move the
knives into or out of the path of the paper web, the said lever being weighted or
otherwise kept in place to prevent the paper from lifting the knives.
x is the brush which co-operates with the knives during the slitting of the paper;
this brush is hinged or pivoted to the stretcher d in such a manner that the
bristles can be in or out of contact with the paper. During the slitting the brush
bears against the underside of the paper as shewn in Figure 2 and holds it up
against the knives, whilst during the adjusting of the machine before the slitting

page_text: operation commences the brush is turned so as to be out of contact with the paper.
The movement of the brush is effected by means of a hand lever y on one end of
the brush.
We in some cases use in connection with the table or stretcher over which the
paper passes a weighted roller z which is carried in two arms ¹, ¹, Figures 2 and 3,
the said arms being pivoted to the said stretcher d and having their free ends
adapted for the attachment of a weight or weights in order to cause the roller z
to bear more or less heavily upon the paper as it passes over the top of the
stretcher.
In using the machine the paper web having been passed over the roller s, under
the rollers z and s¹ and attached to the tubes on the spindle g is drawn through
the machine by rotating the said spindle g by means of the hand wheel r in the
direction of the arrow Figure 2.
When rolls of the desired size have been wound
the spindle g is removed from its bearing and withdrawn from the rolls, the
flanges upon the said spindle being removable to permit of this. During the
time that the paper web is being passed through the machine preparatory to work-
ing, the knife and brush are turned so as to be out of the path of the paper.
We sometimes provide the machine with arms for carrying two or
receiving spindles g as shewn in Figure 6, the two spindles being geared together
(for instance by gear wheels g¹, 9, 9' as shown or by a band or belt running
around pulleys on the two spindles) so that both spindles rotate in the same
direction at the same speed.

The advantage of this arrangement is that alternate strips can be wound upon
different rollers whereby the several rolls are prevented from becoming locked
by the slight overlapping of the strips at the ends as is frequent when all the
strips are wound upon one roller.
When the strips instead of being wound upon paper tubes are wound without
a core or upon a core simply formed of a strip of say brown paper one end of which
is fixed to the receiving spindle, the teeth 1,1 and the means for projecting and
withdrawing them may be dispensed with, that is to say, the spindle g may be
plain or only provided with a rod for holding the ends of the paper strips when
starting to wind the same.
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 slitting machine characterized by the combination with a slitting
knife or knives arranged upon a spindle, of a brush designed to press against the
paper to be slit and to hold it in contact with the slitting knife or knives, sub-
stantially as described.
2. In a paper slitting machine of the kind described a series of knives arranged
to project in a radial or substantially radial direction from a shaft which is
capable of being rotated upon its axis to bring the knives into contact with the
paper or out of contact therewith, substantially as described.
3. The combination with a paper slitting machine of the kind herein before
described of a receiving spindle or spindles provided with teeth adapted to project
from the spindle when rotated in one direction and to be drawn within the spindle
or rotated in the reverse direction, substantially as described.
4. The manufacture and use of the improved paper slitting machine consisting
of the parts constructed and combined, substantially in the manner hereinbefore
described and illustrated in the accompanying drawings and operating as, and for
the purpose, set forth.
