Paper, also Applicable for Cutting Textile Material.
We WALTER WILLIAM COLLEY of 220 Camberwell Now Road, Surrey, Machinist,
and MORRIS HART of 4 Coleman Street Buildings London E.C. Merchant, do hereby
declare the nature of this invention to be as follows:
-
This invention refers to machinery for slitting webs of paper into narrow widths
and if required, simultaneously damping or wetting same for printing and manu-
facturing purposes. The slitting or cutting part of the invention is also applicable
for cutting textile materials into bands.
For newspaper and various other printing machines it is necessary to damp the
paper some days before it is required for printing, this not only necessitates a large
outlay for wages plant and power, but a very large amount of room is required for
the work and to warehouse these rolls of paper; the damping of which requires the
rolls to be unwound and then to be rewound for use. In order to meet the wants
of the printing and other trades we have designed a machine which we think will be
a great boon to the paper makers and printing trade, to enable these rolls to be cut,
reeled and damped at the mill in the most perfect manner, the whole operation taking
about half the time the ordinary mill slitting apparatus now in use requires; thus
saving the printers the trouble cost and waste they now experience in damping the
paper after it has been received from the mill.
The machine according to this invention will slit and reel a web of paper-either
while in the process of making or after a roll has been taken off a paper making
machine-into small rolls any width required with clean cut edges, this we believe
has never been accomplished before. The present cutting machinery now in use,
cutting with rotary cutters do not reel the paper into reels with clean edges, but
these overlap one another, and the cutters have a tendency to leave a serrated edge
and cause a large amount of dust or fine pieces of paper to adhere necessitating the
paper being unreeled and damped to enable this dust to be cleaned from the paper.
By our invention we obtain a clean and regular cut free from dust and as the paper
is being slit and reeled into rolls; it can be damped by means of paper reeling up on
1117

page_text: knives and spacing blocks (hereafter called the cylinder) which conveys a regular
dampness to the paper in a nost uniform manner.
The machine embodying the invention consists of a pair of frames carrying a
cylinder built up in sections by blocks and circular knives to enable any width to be
cut a pair of tension rollers made of wood preferably covered with india rubber, or
of iron fluted to grip the paper; these rollers are driven together at the same surface
speed by means of band and pulleys and are timed to travel slower (by preference
half speed) than cutting cylinder. This cutting cylinder is set in motion by usual
band with tight and loose pulleys. At opposite end of cylinder a pulley is keyed to
convey and drive tension rollers. At each side of side frame and over centre of
A
cylinder an opening is made to admit of a pair of vertical slides working in same.
pair of box bearings are let into each of these slides, such bearings carrying a spindle
built up with wood centres or quills, these bearings are adjusted by means of set
screws to set each spindle on or away from cylinder these slides are connected
together at bottom by means of a bar such bar carrying series of weights used to keep
and press the spindle carrying the wood centres down firm on to cylinder. This
spindle is set in motion by frictional contact with the cylinder. At end of each
frame are bearings to admit spindle with roll of paper as it leaves paper making
machine. Friction collars are placed at each end of spindle. A suitable break is
attached to regulate tension and prevent the rolls from unwinding too freely. The
rim of front friction collar is let into a cup bearing sliding upon a fixed stud with
thread cut on end. This cup bearing works spindle carrying mill roll backwards and
forwards by means of small hand wheel; by this means the web of paper can be
easily adjusted in case the roll should have at any time a tendency to telescope which
is frequently the case owing to the paper being sometimes made thicker at one end
than other.
For preventing the narrow trimming of the mill edge from breaking away we
employ a pair of guides mounted over top tension roller and working on a bar fixed
to side frames. These guides rest on each end of reeling spindle and lay close up to
sides of roll and are arranged to rise and fall as the roll increases in diameter. Bolted
to frame under cylinder is a tank to contain the water for damping the paper. A rod
is fixed to frame and placed close up to cylinder to admit of one end of blanket or
felt being threaded on same, this blanket is then lapped about half way round cylinder
passed over another rod and the other end of blanket is fixed in tank and submerged
under water by this means the blanket conveys a uniform dampness by capillary
attraction to cylinder and as it revolves the blanket always lays against surface of
same, and as the roll of paper is being reeled on to this cylinder every part of the roll
receives a sufficient supply of water. In the place of this stationary blanket we may
employ an endless blanket arranged to revolve at same speed as cylinder by frictional
contact therewith this blanket would then pass over a roller partly submerged
revolving in tank. In that case we employ a fixed scraper to regulate the supply of
water; but we prefer to use the stationary blanket.
:
The mode of working this machine is as follows-The roll of paper is mounted in
bearings unreeled and passed under bottom and over top tension rollers and lapped
round spindle carrying wood centres or quills, the machine being set in motion the
paper is reeled up and cut into small rolls by this spindle revolving on cylinder by
frictional contact therewith. The cylinder is always travelling faster than the paper
the tension rollers acting as brake on roll and allows same to slip on cylinder so that
the edges of the knives travelling faster than the paper a good clean cut is
obtained.

Improvement in Machinery for Slitting or Cutting and Damping
Paper, also Applicable for Cutting Textile Material.
We WALTER WILLIAM COLLEY of 220 Camberwell New Road, Surrey Machinist,
and MORRIS HART of 4 Coleman Street Buildings, London E.C. Merchant, 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:-
By this invention wide webs of paper can be slit into any desired widths with clean
cut edges and evenly wound into rolls and if desired damped for printing purposes
while being cut and wound, the whole operations being continuously performed at the
same time in the same machine. The cutting part of the invention is further suitable
for cutting textile materials into bands and winding the same into rolls.
To enable my invention to be properly understood I will proceed to fully describe
the same with aid of the accompanying drawings.
Figure 2 pian.
Figure 3 front elevation with guard fence removed.
A, frame, secured to suitable bed, B, the cutting and winding cylinder: this cylinder
is formed of a number of blocks or washers C, carried upon a shaft D, revolving in
suitable bearings in frame.
Between each block or as may be desired according to the width of paper to be cut,
is a circular knife E, of slightly larger diameter than the blocks, so that the edges
project a short distance above the circumference of the cylinder.
The blocks C, are pressed tightly together on the shaft D, securing the knives
between them, by being screwed up against a collar F, on the shaft by a screw nut G:
the shaft is revolved by belt from pulley H, keyed on to shaft, by which the machine
is driven.
The paper is cut upon a square or round spindle I, provided with journal ends and
shoulders held in suitable box bearings and revolved by frictional contact with the
cylinder. Preparatory to working, the spindle I, has placed upon it a number of
wooden spools J, upon which the paper is wound and cut, and of a width to correspond
to the cut paper. These spools are secured on spindle against a collar near one end
by a collar on end of a sleeve slipped on the other end of spindle which is sufficiently
reduced for this purpose and secured by nut; the outside of the sleeve forming one of
the bearing ends of the spindle. The spindle is shown in the different figures. with

page_text: is
the spools on but without wound paper. To enable the spindle to rise as the paper
wound upon the spools upon it its bearings are carried in slides K, working in suitable
vertical guides in frame to enable the slides to rise up as shown by dotted view.
These slides are connected together at bottom by a cross-bar L, to hang weights M,
upon to keep the spindle down on the cylinder and give the requisite frictional bite
for winding from the surface of the cylinder. The slides K, can be lifted to remove
the winding spindle by levers N, on cross rod carried in frame, operated by handle N¹;
this can be held down by a hook catch N2. The handles N¹, carry a weight N³ secured
by set screw to automatically enable the levers to reduce the pressure or weight of the
cut rolls of paper on cylinder B, when reeling to large diameter.
O, a web of paper ready to be unwound and cut; the quill of this roll has a spindle P,
passed through it, the ends of which are carried in brake bearings Q, attached to
frame A; one of these bearings is made adjustable by a set screw P₁, to set the roll..
The unwinding of the web O is controlled by the weights P', acting upon the lever P³,
attached to hinged cap of bearings Q, to give a proper tension to the paper.
R, S, are two tension rollers revolved at the same surface speed, which draw the
paper from the web O, and hold it to control the speed at which the winding spindle
revolves so that the edges of the knives may have a higher surface speed-preferably
two to one than the winding spindle, which enables the knives to cut the paper with
a clean and even edge. The difference of the surface speeds at which the cylinder
and winding spindle revolve is made up by the slipping of the cylinder past the
winding paper. The spindle of roller R, has keyed to it a pulley T, driven by band
from pulley U, keyed on shaft D, of cylinder; also keyed on the spindle of roller R,
is a second pulley V, transmitting motion by band to a pulley W, keyed on spindle of
roller S; the pulleys V, and W, being of the same diameter, cause the two rollers R,
and S, to turn at the same surface speed, which as has been explained is preferably
arranged to be about half the speed of the cutting and winding cylinder B; this
difference of speed being obtained by the pulley U being only half the size of pulley T.
X, guides for the ends of the paper while being cut and wound. Each of these guides
are carried on a tube Y, and secured where necessary by set screw: these tubes are
carried on a cross rod Y', secured in framing of machine. Z usual stretcher bar to
support the framing A. Z' guards for roll 8.
The damping of the paper is effected by wetting the surface of the cylinder B,
while revolving this may be done in the following way. Under the cylinder B, is
arranged a tank A¹ for water; B', a band of blanket or other suitable material for
wetting the surface of cylinder B, by which the dampness is conveyed to the paper at
the same time it is being cut and wound. This band is held by a cross rod B², and
against cylinder between knives, by being passed over another cross rod B, from
which it passes down into tank and is secured in bottom, the water rising up the band
by capilliary attraction, sufficient to wet the surface of the cylinder.
E', guard fence for the knives formed of wood, screwed to iron standards E³,
arranged to fit into sockets E³. O', the unwinding paper passing to winding
spindle.
