PROVISIONAL SPECIFICATION.
Improvements in Reeling and Slitting Machines for Paper and
the like.
We, JOSEPH FAUST, of Woking, in the County of Surrey, Paper Maker, and
PERCY JOHN NEATE, of Rochester, in the County of Kent, Engineer do hereby
declare the nature of this invention to be as follows:-
This invention relates to a machine for reeling and slitting paper and the like,
and it is designed to supersede the present complicated machinery employed for.
this purpose by a very much more simple contrivance. In machines of this class
the knife and press rolls have been driven separately and one of the more important
features of this invention is to construct a combined knife and press roll. We
propose to form this knife and press roll of a number of movable rings mounted on
a core, one or more circular knives being inserted between them at any desired
width apart; the rings are preferably pressed together by nuts on the ends of the
core when they will practically form a solid roll. The edges of the knives project
preferably to the extent of the thickness of the paper, and allow the press roll to
run on the paper and by this means the knives are prevented from sinking more
deeply into the roll of paper than is necessary for cutting, thereby avoiding rough
edges. The action is as follows:-
The paper to be slit is preferably led from the roll over a guide and counting
roll and may then pass around the re-reeling roller and under the slitting roller, the
former being in frictional contact with and receiving its motion from a rotating
cylinder or drum. The combined knife and press roll bears upon the re-reeling
roll at any desired point, the knives cutting the paper to the required depth and
width while the rings act as a presser. The knife and press roll is adapted to
adjust itself automatically as the re-reeling roll increases in diameter. As soon as
the re-reeling roll is full the knife roll may be raised a little and the roll of slit
paper taken off, a new centre or core put on the shaft and a fresh quantity of paper
is re-reeled and slitted.
It will be understood that modifications may be made without departing from
the spirit of our invention.

Improvements in Reeling and Slitting Machines for Paper and
the like.
We, JOSEPH FAUST, of Woking, in the County of Surrey, Paper Maker, and
PERCY JOHN NEATE, of Rochester, in the County of Kent, 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 machines for reeling and slitting paper and the like and
it is designed to supersede the present complicated machinery employed for this
purpose by a very much more simple contrivance.
In machines of this class as hitherto constructed the kuife and press rolls have
always been arranged and driven separately.

page_text: The object of this invention is to construct a combined knife and press roll.
To this end we form the knife and press roll of a number of movable rings
mounted on a core, one or more thin circular knives being inserted between them at
any desired distance or distances apart; the rings may be pressed together by nuts
on the ends of the core when they will practically form a solid roll; or they may
be otherwise suitably secured in position.
The edges of the knives project for a suitable distance and allow the press roll to
run on the paper and by this means the knives are prevented from sinking more
deeply into the roll of paper than is necessary for efficient cutting thereby avoiding
rough edges.
In the accompanying drawing
Fig. 1 is a side elevation of a reeling and slitting machine having our invention
applied thereto,
Fig. 2 is a broken front elevation of the combined press and knife roll.
Referring generally to the machine Fig. 1, a is one of the bed plate frames,
b one of the side standards splined for sliding feathers and suitably tied back, c is a
supply reel suitably braked from which the web of uncut paper passes beneath a
measuring and guide roller d over the drum e to the re-reeling or winding reel f
which is driven by frictional contact with the drum e, the latter being centred in
the bed a and actuated by the prime motor. The axis of the reel is carried in
brackets sliding upon the standards 6 and is adapted to automatically rise with
the increasing diameter of the re-reeled paper as shown or in any suitable manuer.
None of the above forms any part of our present improvement.
h,
According to our invention we provide a shaft or core S extending transversely
the full width of the machine; it may be journalled in bearings in brackets such
as B adapted to slide vertically on the standards as illustrated. The said
brackets B are provided with self-acting balancing gear such as is shown at 9:
which is adapted to partially balance the weight of the combined knife and press
roll, the balance weights g being variable according to the thickness and quality of
the paper to be slit; or the combined knife and press roll may be otherwise adapted
to automatically recede as the diameter of the re-reeled reel f increases. Upon the
shaft S are mounted a number of rings or collars R between which are fixed the
circular knives K as in Fig. 2. These collars may be of any suitable width of face
and they are adjustable as to spacing apart; for ordinary work they are fixed in
the required positions by set screws r or otherwise suitably: In use they act upon
the paper web at either side of the knife exactly as press rolls and the knives K
project about inch so as to cut effectually. When heavy or continuous pressure
is required a sleeve such as is shown dotted at T, Fig. 2 of exactly the same
diameter as the collars R may be fitted between each or any set of combined knife
and press rolls K. R. In this case the whole may be pressed together and
tightened up by a nut screwed upon the ends of the core, or one nut N at one end
and a flange N' at the other as shown dotted in Fig. 2, thus making a solid and
continuous press roll.
In action the combined knife and press roll KR bears by its own gravity upon
the web of paper which is to be slit upon the re-reeling reel in the position
illustrated or at any desired point; the said reel being driven by its frictional
contact with the drum e as described drives the combined knife and press roll and
the knives K then cut the paper to the required width, while the rings R (and
sleeves T if used) act as pressers, and the knife and press roll adjusts itself auto-
matically as the re-reeling reel increases in diameter. As soon as the latter is full
the knife roll may be raised sufficiently to allow the roll of split paper to be
removed, and another core put on the axle f¹, then a fresh quantity of paper is
re-reeled and slitted. We have described the combined knife and press roli as
driven by the mere frictional contact of the driven re-reeling reel as we have
found this to be sufficient without mechanical aid, but we would say that it
may be driven otherwise if required in any suitable manner as to which we lay
no claim.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The hereinbefore described improvement in reeling and slitting machines for
paper and the like which consists in arranging the circular slitting knife or knives
to project suitably from the surface of the press roller itself (instead of being
arranged upon a separate axis or axes as heretofore) substantially as described.
2. The construction of the combined knife and press roll substantially as
hereinabove set forth.
