My invention comprises the manufacture of cardboard or pasteboard in continuous
pieces of considerable length, which can, if desired, be cut into sheets of any
suitable size according to the purpose for which it is required.
In constructing apparatus according to my said invention I provide two rollers
for carrying strips of thin paper which are to form the two faces or outer layers
of the cardboard or pasteboard, and one roller for carrying one or more pieces of
thick paper which are to constitute the core thereof. Each of the strips of thin
paper is passed over a cylinder or roller which is partially immersed in a trough or
receptacle containing paste or other adhesive substance. They are then passed
between a pair of rollers with the core of thick paper between them. One roller
of this pair is pressed against the other roller by means of one or more weights
or springs, so that the two thin strips are thereby caused to firmly adhere to
the core.
To prevent the accumulation of the adhesive material upon these rollers, one or
both of the said rollers are partially immersed in water; or other means are
provided for this purpose.
.
The cardboard or pasteboard thus made is conducted from the said pair of rollers,
and is passed around, or between, a series of drying cylinders. It is then wound

page_text: around a reel or drum of sufficiently large diameter to avoid fracture of the card-
board or pasteboard.
If it is desired to give the pasteboard a high degree of finish it is passed between
glazing rolls.
The above mentioned rollers and drum are carried in suitable bearings in a
frame or casing; the pressure rollers, the drying cylinders and the reel or drum are
connected by suitable gearing, and motion is imparted to them in any convenient
manner.
The said reel or drum is so arranged that it can be readily removed and replaced
by a similar reel or drum, when the desired quantity of pasteboard has been wound
upon it.

Improvements in the Manufacture of Cardboard or Pasteboard,
and Apparatus therefor.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly 2
described and ascertained in and by the following statement:-
My invention relates to apparatus for the manufacture of cardboard or paste-
board.
It is customary to make such material of three or more layers, viz; a core
consisting of one or more sheets of thick paper of inferior quality and two facing
sheets or outer layers of thin paper of superior quality. When cardboard or paste-
board is made in this manner in long strips or pieces, it is very desirable that it
should be dried before being wound upon a reel or drum.
By my invention I provide improved means for manufacturing cardboard or
pasteboard in continuous lengths or pieces, that is to say, pieces of such length
that they can, if desired, be cut into a large number of sheets of any suitable size
according to the purpose for which 'they are required. I also provide for drying
the said cardboard or pasteboard and winding the same on a reel or drum.
In some instances, I combine, with my improved apparatus, any suitable printing
and cutting mechanism as hereinafter set forth.
In the accompanying drawing, I have shown how my said invention may be
conveniently and advantageously carried into practice.

page_text: Figure 1 is a side elevation of my improved machine or apparatus, one side of
the frame being removed.
Figure 2 is a side elevation, partly in vertical section, illustrating the manner
of combining cutting mechanism with my improved machine or apparatus.
A is the frame of the machine, B, C are reels or drums, on each of which is
wound a continuous strip a or a¹ of thin paper of any desired width. These strips
form the two faces or outer layers of the cardboard or pasteboard. D is a reel
or drum having wound thereon a continuous strip or length 6 of thick paper, which
constitutes the core of the cardboard or pasteboard. If desired, this strip may be
composed of two or more layers.
E, E are cylinders or rolls which are partially immersed in paste or other adhesive
substance, contained in troughs or receptacles F. G, G are two rolls, one of which
is held with a yielding pressure against the other by means of springs, as at g, or
by one or more weights. H. H are drying rolls or cylinders which may be of any
suitable description.
The strips a, a¹ of thin paper are passed over, and in contact with, the rollers E,
whereby they are smeared or coated on their inner surfaces with adhesive material,
They are then passed between the pressure-rolls G with the core b between them,
the strip a¹ being previously passed around a guide-roller a*. By means of the
rolls G, the strips a, a' are caused to firmly adhere to the core b.
The cardboard or pasteboard c thus made is conducted from the pressure-rolls
and passed around and between the drying rolls or cylinders H, and, after being
dried thereby, is wound around a reel or drum I. This drum should be sufficiently
large in diameter to avoid fracture of the cardboard or pasteboard. If it is desired
to give the pasteboard a high degree of finish, it is also passed around and between
suitable glazing rolls.
To prevent the accumulation of the adhesive material upon the rolls G, the lower
of these rolls is partially immersed in water contained in a trough or receptacle K;
or other suitable means are provided for this purpose.
The above named cylinders or rolls and the reels or drums are carried in suitable
bearings in the frame A; the pressure rolls G, the drying rolls or cylinders H, and
the reel or drum I are connected by suitable gearing and motion is imparted thereto
in any convenient manner.
The reel or drum I is so arranged that it can be readily removed and replaced
by a similar reel or drum, when the desired quantity of pasteboard has been wound
upon it.
My apparatus may be adapted for making strips of cardboard or pasteboard of
any desired width.
My apparatus is very advantageous for use in the manufacture of cardboard or
pasteboard designed to be printed and cut or divided longitudinally and trans-
versely for the production of tickets, labels or the like.
In Figure 2, I have shown how my apparatus may be combined with mechanism
for cutting or dividing the cardboard or. pasteboard longitudinally into strips of
the required width to form tickets or the like. In this Figure, H, H are the
drying rolls or cylinders. L L are two rolls, each of which is provided with a
series of circular knives or cutters secured thereon in any convenient manner,
spaces equal in width to a ticket being left between adjacent knives or cutters.
These rolls are capable of adjustment by means of screws . M, M are small
rollers for holding the cardboard or pasteboard at each side of the cutters and
steadying it while being cut. N, N¹ are reels or drums on which the strips are to
be wound.
The cardboard or pasteboard c is conducted from the drying rolls H around a
guide-roller d, and is passed between the first pair of rolls M, then between the
cutting rolls L, whereby it is cut or divided longitudinally; and then between the
second pair of rolls M. From the last named pair of rolls, every alternate strip o¹
is conducted to, and wound around, the reel or drum N, and the remaining strips c²
are conducted to, and wound around, the reel or drum Nr.

page_text: I sometimes combine, in the same machine, mechanism such, as that above
described for the manufacture of cardboard or pasteboard, mechanism for printing
thereon and mechanism for cutting or dividing the said cardboard or pasteboard
either longitudinally or transversely, or both longitudinally and transversely, to
form continuous strips of tickets or separate tickets. The printing mechanism is,
in some instances, arranged to print consecutive numbers on the said tickets.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same. is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :—
First The combination of drying rolls or cylinders with means for making.
cardboard or pasteboard, as, and for the purpose, above specified.
Second-The improved machine or apparatus (with or without the glazing rolls
or cylinders) constructed substantially as described with reference to Figure 1 of
the drawing and operating as, and for the purpose, specified.
Third The combination of my improved apparatus with cutting mechanism,
substantially in the manner described with reference to Figure 2 of the drawing,
for the purpose specified..

Fourth-The combination of my improved apparatus with printing and cutting
mechanism for the production of tickets or the like, substantially as set forth.
