I PETER STEWART of Fettykill Paper Mills, Leslie, Fifeshire, Paper Maker do
hereby declare the nature of my Invention for "IMPROVED APPARATUS FOR
DIVIDING OR CUTTING WEBS OF PAPER INTO STRIPS AND WINDING THE SAME INTO
ROLLS to be as follows:-
ม
•
My invention relates to apparatus of improved construction for dividing or
cutting webs of paper into strips and for winding such strips into rolls or narrow
webs.
'
The improved apparatus comprises a strong frame carrying in bearings at the
upper ends of its side standards a rotating shaft fitted with circular discs or cutters
which serve to cut the web of paper passing under them on its way from a roll or
beam at the back of the machine to a series of winding spindles in front. Under
the rotating cutters the web of paper is carried across two stationary shafts or
mandrels between which is fitted adjustably a plate formed with slits or slots into
which the cutting edges of the discs or cutters pass; and in its passage the web is
divided by the cutters which with the slotted plate form shears to cut the web
longitudinally. Form the cutters the strips into which the web is cut pass down-
wards the alternate strips passing round a smooth shaft near the front of the
machine and on to winding spindles there and the remaining strips down to a
lower shaft and a lower series of winding spindles. The adjacent edges of the
strips in leaving the cutters, or the mandrel close to the cutters pass off in different
lines and the alternate strips are wound on spindles at different points. Each
winding spindle is arranged to wind two strips the spindle being carried by a
bracket hinged on or to the shaft behind or to the frame and being provided with
a toothed pinion at the centre of its length whereby it is driven from a spur wheel
geared to it the spur wheels for the upper series of spindles being on one rotating
shaft and those for the other series on a lower shaft and both shafts being driven
by gearing or the spindles may be driven by friction wheels or by bands or cords.
The winding spindles have each on the periphery of the part which forms the
core for the rolls of paper a longitudinal recess or groove parallel to the axis of the
spindle and the outer part of the spindle beyond the core is reduced to a smaller

page_text: diameter. On the latter part a removable cap or ferrule is mounted into one end of
which is fixed a long needle or pin at a radius to correspond with the groove afore-
mentioned and this pin lies therein when the cap is in position. A hole is drilled
in the shaft at the inner end of the groove to steady the point of the pin or
needle..
The use and purpose of the needle and groove is to clip or grip firmly the end of
the strip of paper to be wound. This is done by passing the needle over the paper
pressing it into the groove and sliding the cap on to the point of spindle and
inserting the point of needle into the hole above mentioned. In fixing the strips of
paper to the spindles they can be so adjusted that all start with the same tension.
To remove the roll from the spindle the cap and needle are withdrawn and the
roll slipped off the core which is slightly tapered to facilitate removal.

I, PETER STEWART, of Fettykill Paper Mills, Leslie, Fifeshire, Paper Maker, do
hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accompanying Sheet of
Drawings, and to the letters and numerals marked thereon that is to say:
My invention relates to apparatus of an improved construction for dividing or
cutting webs of paper into strips and for winding such strips into rolls or narrow
webs.
And in order that the full nature and novelty of my said Invention and the
mode and means of putting the same into effect or practice may be properly
understood, I shall now proceed to describe the several figures on the Sheet of
Drawings which I have hereunto appended for that purpose, the same reference
letters indicating the same parts in all the figures where shown.

Figure 1 is a longitudinal front elevation, Figure 2 a corresponding plan, both
having many of the parts shown in section, (the latter showing only one revolving
cutter 6 and double winding or rolling spindle), for showing these parts more
clearly with the least possible repetition of lines and parts, and Figure 3 is
a transverse vertical section corresponding to and taken on the line 1 1
in Figure 1, all of a complete machine, showing a general arrangement and
combination of my improvements and parts of the apparatus for dividing or
cutting webs of paper into strips, and winding or rolling the same into rolls.
Figures 4 and 5 are transverse and longitudinal sections, respectively taken on
the lines 1 -1 and 2 -

Referring to these Figures 1 to 3 my said invention or improved apparatus consists
all as follows:-The framing consists of two strong open rectangular side or end
frames or standards A, A, well bound together by longitudinal stays A¹ and
stationary guide and other bars C, C, F; the whole being secured to any
suitable foundation or floor at A¹¹. On the upper back end of these standards A, A,

page_text: "
two vertical shifting and setting bearing brackets A² are screwed, carrying in
suitable bush bearings at top A³, the rotating shaft B, actuated by a driving belt,
from any suitable adjacent motion shaft, passed over the pulleys B¹ on its over-
hung end.
This shaft B has mounted on it a set of thin sharp circular or disc
cutters b, secured between two gripping bosses 61, 62, fitted to shift and be screwed
to the shaft B, in the positions desired to suit the width of strips of paper to he
cut. Thirteen cutters 6 are here shown so mounted on the shaft B to cut twelve
strips out of the web of paper, (indicated at p p as passing under them) from the
roll of paper or guide beam P, placed in bearing brackets P¹, secured to the back
of the frames A, the strips p¹, pl, when cut passing on to a series of winding
spindles D, d, in the upper and lower front part of the machine. The tension on
the web of paper may be regulated by a friction or tension " pace on its beam P.
The web paper p, p, indicated by dotted lines in Figure 3, is first passed round the
under and front polished surface of a stationary guide mandrel C, preferably hollow
and secured in suitable brackets A¹¹1, in the side frames A. The web of paper is
then passed up over the top surface of two similar smooth surface guide shafts or
bowls C¹, C, below and a little distance apart under the line of the rotating disc
cutters b. Below each cutter b, a double segmental block or plate c is fitted,
between and bearing on the upper inner surfaces of the paper guides C¹³, C³, and
having a narrow sharp edged slit c¹ in its upper surface, into which the sharp edge
of the cutting disc b passes and rotates. This slotted plate c c¹ is fitted with a
'screw stud cl projecting down between the guide bars C1, C2, and has an inverted
double segmental plate c³ passed over the screw to bear up on the under inner
surface of the bars, with a strong thumb screw nut c³ below on the point of the
screw c¹¹ this thumb screw on being tightened up secures the bearing slotted
plate cc above to the bars C1, C2, in any position to suit its disc cutter b; all as
will be particularly seen in Figure 3, and the large detail views of these parts in
Figures 4 and 5. The web of paper p, p, in its passage over the guides C1, C2, and
slotted plate c, c¹, is divided by the cutters b,-which with the slotted plate c c¹
form shears to cut the web longitudinally,-into six strips, (indicated by the dotted
lines p, p¹), the cutters b revolving preferably in the same direction as the web of
paper and at a considerably higher speed; but this may be varied considerably.
The adjacent edges of the strips of paper as cut on leaving their cutters b, c, c¹,
and guide mandrel C, soon pass off in different directions to clear each other.
The alternate strips pl pass round under the smooth surface guide shaft C¹¹, a
little below and in front of the guide C, thence forward on to the upper set of
winding spindles D, d, in front of the machine; the remaining alternate strips pl
passing straight down to and under the lower guide shaft C1 forward to the lower
series of winding spindles D d in front below the first set. The alternate
strips p p passed forward at the different heights under the guides C, C, to the
upper and lower set of spindles D d, D'd, are wound on these. Each winding
spindle D or D¹ is made double, with two overhanging ends d, d, to wind two strips
into rolls, one on each end; and it is carried in a longitudinal horizontal line in
double bearings E¹ in the front open or slotted end of a transverse carrying lever
bar or bracket E, which is hinged or jointed to oscillate up or down on the guide
bar Cor C The weight of the upper and lower set of hinged lever bars E
carrying their respective sets of winding spindles D, d, is carried by bars F, mounted
below them in brackets at their ends in the side frames A, A, and each lever E is
set and secured (in proper position for its spindles d, d, to wind each strip evenly
into a roll), in the upper gab end F' of a short shifting and securing arm F¹ with
pinching screw F11 below for securing it to the bar F. A swivelling cover f, is
fitted on the top of the gab F, with thumb screw f¹, above the lever E, for
securing or releasing this, when it has to be raised to stop the winding of its
spindle D, d, to remove the roll therefrom when wound and attach the end of the
strip for winding another roll. The levers E, with their spindles D, d, may be thos
easily raised or lowered by a counterweighted cord or other equivalent attached at
their outer free ends Eu

page_text: Instead of these oscillating levers described for carrying the winding spindles
these might be carried on reciprocating bars or frames for putting the spindles into
or out of action.
A toothed pinion g, is mounted on the centre of each spindle D, between its.
bearings E¹, whereby it is driven when lowered with its carrying lever E E' into
gear with the spur wheel g¹. The spur wheels g¹, g¹, for the upper series of
spindles D are mounted on one rotating shaft G, and those g¹, g¹, for the other or
lower series D¹ on a lower shaft G. Both of these shafts G, G', are carried in
suitable journal bearings in the frame A and driven by pinions G² on their overhung
ends, gearing into a large spur wheel G₁, carried on a strong stud centre G³ in the
one side frame A; this wheel G" being driven by a pinion Q on a second motion
shaft H, carried in a journal bush bearing block H¹, in the side frame, and in
another Hat its outer end on any suitable support or foundation part of the
building. This shaft H may be driven by a belt passed over the pulley H³ from
the same shaft that actuated the cutter-shaft-B.
The duplex winding spindles D, d, have each on the periphery of the parts d,
which form the core of the rolls of paper, (indicated by a dotted line poll in Figure 6),
a longitudinal recess or groove d¹, formed parallel to the axis of the spindle d;
while the inner and outer parts d", d¹¹, of the spindle beyond the core part d is
reduced to a smaller diameter. On the outer end part d¹¹ a movable cap handle d*
with ferrule or collar d³ is mounted, into the inner end of which the outer end of a
long needle or pin e is fixed in a position and at a radius to correspond with and
enter the groove before mentioned. This pin e lies in the groove d¹ when the
cap d' is in position. A hole e¹ is drilled in the end journal part d of the shaft D
at the inner end of the groove d², to secure the point of the pin or needle e, all as
particularly shown in Figures 6 to 11. The use or purpose of the needle e and
grooved is to firmly clip or grip the end of the strip of paper p¹ or pl to the
spindle d to be wound into a roll p. This is done by passing the end of the paper
across the groove d¹ and pressing the needle over the paper down into the groove d¹,
and then sliding the cap d' on to the point of the spindle d, and inserting the
point of the needle e into the hole et above mentioned. In fixing the strips of
paper to the spindles, they can be so adjusted that all will start with the same
tension.
To remove the rolled strips p from their spindles d, the end cap d³ and needle e
of each, are withdrawn, and the roll slipped off the spindle d, which may be very
slightly tapered to facilitate removal.
Although the winding spindles D, d, have been shown as driven from their
actuating shafts G, G, by toothed wheels g, g', and these shafts also by toothed
pinions G, yet friction wheels might be employed instead of these; or in the latter
case friction bands or cords might be used, and when this was done, these might be
used to regulate the tension on the strips of paper while being wound.
