PROVISIONAL SPECIFICATION.
Improvements in Paper Slitting and Re-reeling Machines.
I, DAVID NOBLE BERTRAM, of St. Katherine's Works, Sciennes, Edinburgh,
in the County of Midlothian, North Britain, Engineer, do hereby declare the nature
of this invention to be as follows
This invention relates to a machine for slitting and re-reeling a web of paper
into various widths and specially to treat highly glazed, or enamelled papers.
At
same time it will treat the ordinary classes of paper.
The combination being that as the paper is wound up by friction plate and
spindle, while being wound on said spindle or bobbin, it is cut into different
widths, and the contact of knives with the paper is automatically regulated. The
objection to a reeling and slitting machine in which a drum is employed for winding
up the paper as it is cut is thus overcome. With highly glazed or enamelled
papers the drum causes it to slip and become unequal on ends and soft on body.
No reeling machines have yet been introduced with the combination of reeling up
slit web of paper with the friction plate and knife slitting it as it is being wound up.

Improvements in Paper Slitting and Re-reeling Machines.
I, DAVID NOBLE BERTRAM, of St. Katherine's Works, Sciennes, Edinburgh,
in the County of Midlothian, North Britain, Engineer, 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 improvements in paper slitting and re-reeling machines,
for slitting and re-reeling a web of paper into various widths, and the said machine
is especially applicable for treating highly glazed or enamelled papers, though at
the same time it may be applied for other classes of paper.
:
The invention consists in the combination of parts whereby, as the paper is
wound up by friction plate and spindle on the spindle or bobbin it is cut into
various or different widths by one or more knives the contact of which with the
paper is automatically regulated.
By my invention the objection to a slitting and reeling machine in which a drum
is employed for winding up the paper as it is cut, is thus overcome, for when
treating glazed or enamelled papers on such a machine, the drum causes the paper
to slip and become unequal on ends, and soft on the body.
But in order that my said invention may be more readily understood and easily
carried into effect I will proceed to describe the same with reference to the
accompanying explanatory sheets of drawings.
Figure 1 is a side elevation and Figures 2ª and 2 form a plan (2ª being the back
and 2 the front portion respectively) of my improved slitting and re-reeling
machine.

page_text: Referring to the said drawings I employ a suitable framework arrangement A, A¹
having the necessary means for carrying the working parts. The frame A
having removably mounted in its journals a the reel of paper B that has to be
slit aud re-reeled: the spindle of said reel B being geared by means of
spur or other gearing with the wheel C of an automatic brake or drag
arrangement hereafter referred to. The paper after leaving the reel B passes
down and partly around the leading rollers D and E, the former one D of which
regulates the brake arrangement, that is to say, the said roller D is carried by two
swinging arms e mounted on a cross shaft c¹ carried by the framing A': the front
end of the said shaft c' has mounted on it an operating handle having a tail
piece or front arm c² which is adjustably attached to the one end of a double-armed
lever C2 which is adjustably connected to the frame A and provided with an
adjusting weight rod c³. The frame A has pivoted to it, above the brake wheel C,
an arm having a wood or other block C³, and connected at its other end, by
means of a depending rod or bolt co to a lower arm having a wood or other block C
and guided at its other end which is actuated up or down and so cause the
blocks C3, C4, to bear with a lesser or greater effect upon the periphery of the brake
wheel C, by means of the bent arm of the lever (2 and thus automaticaly
regulate the speed of the reel B.
The paper after leaving the leading roller E passes partly around the drawing in
rolls F and G which are driven by the main driving shaft H of the machine by
spur gearing or otherwise. The paper then passes over the guide roll J and down
between the trimming knives K, K', which trim the web to the width required,―
said knives K and K being mounted on two cross shafts k, k¹, mounted in adjust-
able bearings and driven by the main shaft H by spur or other gearing.
The trimmed web of paper is led over the leading rolls L, Q, on to the spindle M
upon which the web is to be re-reeled or wound. The said spindle M being
driven in the usual manner by a friction plate arrangement, composed of two friction
plates N, N', friction pulley N2, belt and belt driving pulley Na, friction regulator N*
and gearing Nº.
In ke
In order to cut or slit the web of paper as it is being wound on the spindle M
I employ one or more slitting knives O, mounted on a revolving shaft or spindle P
carried by two lever arms P P which are mounted at their other ends to a cruss
shaft P, said shaft P having a double pulley På mounted loosely on it, so as to
enable the spindle and knives () to be driven or revolved by the main shaft II
through the medium of the two belt and pulleys P, I without in any way affecting
the length of the belts during the rising or falling of the knives ().
manner mount underneath the spindle Ma leading roll Q which is carric I by
two lever arms Q', Q, mounted on the shaft Q which is conuretel to the shaft 1
by two, four or more spur segments R, in such a manner that as the lending roll Q
is moved downwards by the gradually increasing diameter of the web as the paper
is wound on the spinille M, the slitting knives O are correspondingly rail upwards,
and to the sanie degree, and thereby maintained in the same relative position to the
surface of the web as it increases in diameter.
To affect or regulate the depth of contact which the slitting knives M have with
the web, the shafts P3 and Q3 are mounted in adjustable solid bushes S carried in.
guide standards S¹ and provided with adjusting screws s mitre or bevel gearings,
cross shafts and handwheel s³, thus enabling the knives O to be raised or lowered
while the leading roll Q is in contact with the web on the spindle M. The shafts P³
and Q if raised, will therefore take the knives () out of contact, or lessen their contart
with the web, while if lowered, the reverse action will take place. To enable the
knives () to be retained out of contact with the web so as to enable the web being
taken out of the machine or while commencing a new web, I mount on the shaft (23
a suitable operating handle arrangement.
The whole of the foregoing arrangement thus forms a very efficient machine for
trimming, litting and re-winding or re-reeling paper of various kinds, though it is
nore especially applicable to hard glazed or enamelled papers.

page_text: 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 [
claim is :-
1st. In paper slitting and re-reeling machines, the combination of the winding
up spindle driven by friction motion, with the slitting knives above and the leading
roll below the web being re-wound, all substantially as and for the purposes herein-
before described and shewn in the accompanying drawings.
2nd. In paper slitting and re-reeling machines, the improved means whereby the
slitting knives are automatically raised so as to maintain the same relative position
to the surface of the web all through the operation, substantially as herein before
described and shewn in the accompanying drawings.
