COMPLETE SPECIFICATION.
Improvements in Machines for Cutting into Strips and Reeling or
Winding Paper, Cardboard, Cloth, and similar materials.
I, FRANCIS MEISEL of 26 to 34 Norfolk Avenue, Boston, United States of
America, Works Superintendent, 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 an improved machine for cutting into strips paper,
cardboard, cloth, and other similar material, and reeling or winding it up into rolls,
and has for its object to perform these operations in a more perfect and satisfactory
manner than heretofore. To this end the invention consists in certain novel com-
binations of parts and details of construction as hereinafter set forth and specifically
pointed out in the claims.
To clearly explain the invention reference is made to the accompanying drawings
which form part of this Specification, and in which :-
Fig. 1 is a front elevation of the improved machine for cutting into strips and
winding paper, cardboard, or the like, a portion of the paper being operated upon
and also a portion of the cutter shafts in front being broken away to show the
parts behind.
Fig. 2 is a transverse vertical section through the centre of the machine.
Fig. 3 is a side elevation of the machine.
Fig. 4 is an enlarged detail of one of the small cutter shafts and a portion of the
larger cutter shaft which co-operates therewith.
Fig. 5 is a sectional detail of the large cutter shaft illustrating the manner in
which it is supported at its ends.
Fig. 6 is a sectional detail on the line e a of Fig. 1, showing the arrangement
of the gears inside the framework at one end of the machine.
Fig. 7 is a plan showing the swinging pressure roll frame at the top of the
machine.
Fig. 8 is a sectional detail on the line y y of Fig. 1, showing the arrangement of
the journal boxes of the small cutter shafts.
In the said drawings, A represents the framework of the machine, outside of
which upon a suitable stud formed at the end of a tie-bar 10 is mounted the
driving pulley B, upon the hub of which is a pinion C which meshes with and
drives the gear D secured to the end of a friction feed or winding cylinder E
consisting of a tubular shell or core-shaft 12, most clearly shown in Figs. 4, 5
and 6, over which are placed a series of thin steel cutting discs a, and rings or
collars of the same diameter, the collars being chamfered off at one edge as
seen in Figs. 4 and 5, to allow the smaller cutting discs c, Figs. 1 and 4, to
co-operate therewith and cut the paper into strips of the desired width.
The cutting discs a are made reversible in order that both edges may be
utilized, and the rings or collars may be of different widths, and may be so arranged
in connection with the discs e as to cut a series of strips of different widths at
the same time. The cylinder E is provided at one end with a supporting shaft 15,
the journal of which runs in a box or bearing in one side of the framework,
while the opposite end of the cylinder E is supported by and runs upon a sliding
centre pin e which enters a conical recess in a plug driven into the end of the
core shaft 12 as seen in Fig. 5, said centre pine being held in position by a
screw g, Fig. 1, provided with a crank-handle and mounted in an arm i provided
with a hub or sleeve k turning freely on a stud outside the framework formed on
one end of the tie-bar 10, whereby the armi with the screw g may be readily

page_text: swung to one side to permit the centre pin e to be withdrawn to enable the cutting
discs and collars on the cylinder E to be quickly removed and changed to cut strips
of different widths.
At one end of the cylinder E is a shoulder 1, Figs. 4 and 5, and at the opposite
end a threaded collar or nut m of the same diameter as the rings and discs, and
provided with holes n for a wrench, whereby said nut may be screwed over one end
of the core-shaft 12 tightly up against the last ring of the series to clamp the rings
and cutters upon the cylinder.
On the supporting shaft 15 of the cylinder E inside the framework is a gear p
which meshes with and drives the gears q, r, s, Figs. 1 and 6, fast on the shafts G,
which carry the small circular knives or cutting discs c secured thereto by means
of screws t, whereby they may be adjusted longitudinally on said shafts to
correspond to the positions of the large cutting discs a of the cylinder E with
which they co-operate.
The cutter shafts G have their bearings in boxes w which are placed as seen
in Figs. 4 and 8, in radial slots a' in the sides of the framework A, in suitable
recesses at the bottom of which are placed spiral springs which bear against the
'boxes w, and tend to force the same outward against the swinging buttons or
latches which extend thereover, as seen in Figs. 1, 3 and 8, whereby when
the bolts don which the buttons are pivoted are loosened, or the buttons are
removed or swung to one side, the springs 6 will force the shafts outward
away from the cylinder E, thereby withdrawing the smaller cutters c out of
contact with the large cutting discs a on said cylinder, as is necessary to permit
the end of the roll of paper or other material to pass between the larger and
smaller cutters at the commencement of the operation, or when it is desired to
remove or adjust the cutting discs for strips of different widths.
The boxes w at the right hand end of the machine are each provided with a
'tubular extension 16 containing a spiral spring 18, as seen in Fig. 4, and dotted in
Fig. 1, which acts against the adjacent end of the shaft G and serves to force it in
the proper direction to produce a lateral separation of the cutting discs a and c,
which should be effected before the shaft G is forced away by the springs b¹ from
the cylinder E. At the opposite or left hand side of the machine the boxes wo are
each provided with a tubular extension e', to the outer end of which is fitted with a
check nut 20, a screw f' which bears against the adjacent end of the shaft G,
whereby when the screw is turned in by means of its handle 25, the shaft G will
be moved longitudinally against the influence of the spring 18, and in this manner
the entire series of cutters c on the shaft G may be simultaneously adjusted laterally
to bring them into proper working contact with the cutting discs a of the cylinder E,
thereby avoiding the delay and inconvenience of setting up each cutter separately
"and independently as has hitherto been customary, and insuring a perfect and
uniform working contact between the cutting discs as required to produce a clean
sinooth cut.
In the same manner all of the cutters c upon a shaft G can be withdrawn or
separated laterally from their co-operating cutters a at a single operation by a
slight backward movement of the screw f' belonging to said shaft which will
permit the spring 18 at the opposite end to force the shaft in the proper direction
to effect this movement or adjustment.
When it is desired to cut very narrow strips of paper, the rows of discs c may be
arranged as shown in Fig. 1, in connection with their counterpart cutters a, so that
those of one row will sub-divide the strips cut by the row above.
The paper or other material to be cut into strips and reeled up is taken from a
roll H, Figs. 2 and 3, mounted on a shaft g' having its bearings in the framework
of the machine, the paper thence passing under a guide roll over a guide roll
and under and partially around the winding and cutting cylinder E where it is cut
into strips by the circular cutters a and c, said strips being then wound up on.a
core-shaft or mandrel I, and forming a roll K which rests partially on the cylinder E
and partially on another winding drum or cylinder L of the same diameter. and

page_text: parallel with the cylinder E. The shaft of the cylinder L has secured to it at one
end a gear k, Figs. 3 and 6, which meshes with and is driven by an intermediate
gear which is mounted upon a stud projecting from the framework, and meshes
with and is driven by the gear p at the end of the cylinder E. The face of the
gear is double the width of the gear p to enable it to engage and drive the gear k
which lies in a plane on one side of the gear p as seen in the upper portion of Fig. 6.
By thus arranging the gears p, k¹, in different planes I am enabled to bring the
surfaces or peripheries of the two cylinders E, L, very close together as is necessary
to enable me to use a very small core shaft or mandrel upon which to wind the cut
strips. The two cylinders E, L, revolve in the same direction, but the cylinder L
the surface of which is preferably roughened, revolves with a greater surface
velocity than the cylinder E, by reason of the gear being of smaller diameter
and having a smaller number of teeth than the gear p, and said cylinders form
friction feed or winding cylinders which serve to rotate the roll K by frictional
contact therewith, and as the said roll increases in diameter, the ends or journals of
the core or mandrel I on which it is wound rise vertically in guide grooves or
ways m', Figs. 2 and 3, in the opposite sides of the framework. "By thus causing
the cylinder L to revolve with a greater surface velocity than the cylinder E the
cut strips are kept stretched over the cylinder E and tightly wound on the core
shaft or roll, one close against the other without interlapping whereby the cut rolls
can be readily separated and removed from the core shaft.
An auxiliary friction winding and pressure roll M, bears upon the top of the roll K
and is rotated by mechanism to be presently described with a surface velocity as
great or greater than that of the friction winding cylinder L which together with
its downward pressure insures the positive rotation of the roll K, particularly when
the diameter of the latter is small at the commencement of the operation, and its
weight consequently light. The roll M is mounted in a pair of swinging arms p', p',
the ends of its journals fitting within the vertical grooves or ways m', whereby as
the roll M is raised, it is kept directly over the centre of the roll K, as shown in
Figs. 1, 3 and 7.
The arms p', pl, are secured to an oscillating shaft N, supported at its opposite
ends in bearings in the ends of two swinging arms 9', 9', secured to a shaft.r
oscillating in bearings s', s', in the framework A; said arms q', 9', being provided
with adjustable weights t¹, t¹, for varying the pressure of the roll M, on the roll of
cut strips K, which is thereby pressed against the friction winding cylinders E, L,
with sufficient force to insure its being properly rotated to cause the cut strips of
paper to be tightly wound into a solid roll. To one end of the roll M, is secured a
pinion to, Figs. 1 and 3, which meshes with and is driven by a gear a², having
fastened to one side a sheave or pulley 62, Fig. 2, said gear and pulley being
mounted on a stud c² projecting from the inner side of one of the arms p', as seen
in Fig. 1.
P is a gear mounted upon a stud projecting from the framework, and meshing
with and driven by the gear k' of the cylinder L, as shown in Figs. 2, 3 and 6,
said gear P carrying a sheave or pulley from which motion is communicated to
the pulley b² and gear a² by means of a belt which runs over two independent
pulleys, Fig. 1, running loosely on a stud g², Fig. 2, projecting from the end
of a bell-crank lever R, fulcrumed at h2, and having pivoted to its shorter arm a
rod, the lower end of which slides in an eye or guide k², between which and
an adjustable collar it is encircled by a spiral spring m³ which tends to force
the rod upward and thereby keep the belt Q at all times tightly stretched as
required, the spring m² yielding to the movement of the bell-crar lever R as
the pressure roll M, and pulley are raised by the increase in dieter of the
roll K as the cut strips are wound or reeled up thereon.
At the upper ends of the grooves m¹ are lateral recesses or notches q², Fig. 2,
for the reception of the journals of the pressure roll M, when it it is desired to hold
the same in a raised position out of the way of the roll K.
