1, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention a communication to me from
abroad by Eugène Brissaut of 117 Rue de Vaugirard, Paris, France, Engineer, to be
as follows:-
This invention relates to an improved machine for cutting or dividing into strips
and reeling at one operation, paper to be used for machine made cigarettes, and other
purposes and the invention consists more particularly in an arrangement of expansible
imandrel mounted either above or at one side of the counterpart or bed cutting
cylinder, by which combination and arrangement, novel results are obtained.
A number of reels are formed simultaneously upon the same mandrel, the strips
forming the reels being of exactly the same breadth throughout the whole length of
paper cut up, and being wound with perfect regularity, so as to be especially suited
for use in cigarette machines, and being easily detachable from the winding
mandrel.
The principle of the invention is illustrated in the accompanying drawing forming
part of this specification, the details of construction being capable of modification.
Figure 1 is a section showing the general arrangement of the machine. Figure 2 is
a front view of part of the machine. Figure 3 shews details of the expansible
mandrel. Figure 4 shews one of the cutting discs with its counterpart, and Figure 5
shows one of the reels of paper produced in the machine, the three latter figures
being drawn to a larger scale."
The same letters of reference indicate the same parts in all the figures.
The roll of paper to be cut up and reeled is placed at a whence the paper follows
the direction indicated by the arrows in Figure 1 and passes round a roller b which
is grooved as shewn more clearly in figure 4, to form with the discs g, pairs of
circular shears by which the paper is severed into strips which are immediately
wound upon the paper rings e, corresponding to the width of the strips and slipped
onto the expanding mandrel c.

page_text: The mandrele rests upon the rollers b d and is rotated by surface contact, the
friction increasing proportionately to the diameter and weight of the reels, so that
the strips are wound with the proper amount of tension.
The strips correspond in width to the distance between the pairs of cutters, and the
rings e on which they are wound are slipped onto the expansible mandrel e (shown
separately in longitudinal and transverse section in Figure 3) after slackening the
mandrel by screwing back the cone f, the mandrel being then expanded to hold the
rings tight by screwing up the cone so as to force apart the segments composing
the mandrel.
The cutters g are mounted in forked arms all fixed on a shaft h on which they are
adjusted with regard to the counterpart cutters on the cylinder b and to ensure
constant contact of the cutters, the arms are jointed and acted on by springs i so
as to press the cutters against their counterparts on cylinder b, from which they
receive their motion. The shaft has an arm k resting against set-screws / by which
the position of the cutters is adjusted towards or away from cylinder b. The
expanding mandrel e is mounted as close as possible to the cutting point so as to
avoid any lateral deviation of the strips and ensure their being wound evenly and at
the proper tension.

page_text: COMPLETE SPECIFICATION.
An Improved Machine for Cutting into Strips and Reeling Paper.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by Eugène Brissaut of 117 Rue de Vaugirard, Paris, France, Engineer),
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 an improved machine for cutting or dividing into strips
and reeling at one operation, paper to be used in the making of cigarettes by
machinery and other purposes. The invention relates particularly in an expansible
mandrel mounted either above or at one side of the counterpart or bed-cutting
cylinder, by means of which a number of reels may be wound simultaneously upon
the same mandrel, the strips forming the reels being of exactly the same breadth
throughout the whole length of paper cut up, and being wound with perfect
regularity so as to be especially suited for use in cigarette machines, and being easily
detachable from the winding mandrel.
The principle of the invention is illustrated in the drawing accompanying my
provisional specification, the details of construction being, however, capable of
modification. Figure 1 is a section showing the general arrangement of the machine.
Figure 2 is a front view of one end of the machine which may be made of any width
desired. Figure 3 shows details of the expansible mandrel. Figure 4 shows one of
the cutting discs with its counterpart, and figure 5 shows one of the reels of paper
produced in the machine, the three latter figures being drawn to a larger scale.
The same letters of reference indicate the same parts in all the figures.
The roll of paper to be cut up and reeled is placed at a whence the paper follows
the direction indicated by the arrows in figure 1 and passes round a roller b which is
grooved as shown more clearly in figure 4 so as to form with the cutting discs g,
pairs of circular shears by which the paper is cut into strips which are immediately
wound upon tubular cores or rings e, of paper, corresponding to the width of the
strips, slipped onto the expansible mandrel c.
The expansible mandrel c, or rather the cores e and paper wound thereon, rest upon
the rollers bd, which are rotated in the direction of the arrows by the gearing shown
in figures 1 and 2, and the mandrel is rotated by surface contact with rollers b and d,
the friction increasing proportionately to the diameter and weight of the reels, so
that the strips are wound with the proper amount of tension.
The strips exactly correspond in width to the distance between the several pairs of
cutters, and the rings e on which they are wound are slipped onto the expansible
mandrele (shown separately in longitudinal and transverse section in figure 3) after
slackening the mandrel by screwing back the cone, the mandrel being then expanded
to hold the rings tight by screwing up the cone so as to force apart the segments
composing the mandrel.

page_text: The rings when thus placed side by side upon the mandrel form a complete
cylinder upon which to wind the paper strips and the reels thus formed can be readily
removed one by one after first slackening the mandrel in the manner above
explained.
The cutters g are mounted in forked arms all fixed on a shaft h on which they are
adjusted with regard to the counterpart cutters on the cylinder b and to ensure
constant contact of the cutters, the arms are jointed and acted on by springs i so as
to press the cutters g against their counterparts on cylinder b, from which they
receive their motion by frictional contact.
The shaft has an arm k resting against set-screws / by which the position of the
cutters may be adjusted relatively to cylinder b.
The expansible mandrel is mounted as near to the cutting point as possible so as to
avoid any lateral deviation of the strips and ensure their being wound evenly and
at the proper tension.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A machine for cutting or dividing into strips and reeling cigarette and other
paper, in which the paper is cut while being drawn off the roll and directly at or
near the point at which the strips are wound onto the reels, the paper being drawn
off and wound up by frictional contact with the counterpart cutting cylinder itself,
as described.
2. In a machine for cutting and reeling paper as described, the combination of
the cutting discs, the counterpart or bed cutting cylinder, and the expanding mandrel
for carrying the reel cores or rings, the whole arranged to operate as and for the
purpose specified.
3. In a machine for cutting and reeling paper as described, the mode of operating
the cutting discs by means of the counterpart cutting cylinder, as described, for the
purpose specified.
