for an Invention of "AN IMPROVED MODE OF AND MEANS FOR SECURING
TOGETHER THE EDGES OF SHEETS OF PAPER, LEATHER, AND OTHER MATERIALS
FOR VARIOUS PURPOSES."

PROVISIONAL SPECIFICATION left by Leonide de Horwath at the Office
of the Commissioners of Patents on the 1st December 1880.
"AN IMPROVED
LEONIDE DE HORWATH, of Paris, in the Republic of France.
MODE OF AND MEANS FOR SECURING TOGETHER THE EDGES OF SHEETS OF
PAPER, LEATHER, AND OTHER MATERIALS FOR VARIOUS PURPOSES."
The object of this Invention is to secure together without the use of any adhesive
substance the edges of sheets of paper, leather, and other materials which are
capable of retaining an embossed impression, to be used in the manufacture of
envelopes, bags, artificial flowers, and for other purposes.
To this end the materials to be joined or secured together are subjected at the
part determined upon to compression between two striated or grooved surfaces.
These surfaces are of such form and dimensions as will suit each particular case,
and they are so arranged as to cause those parts of the material which are at the
time under compression to enter the one into the other so that they will remain
united, or so to speak be artificially welded together. This fastening will have
such solidity that, in the case of paper, it will be impossible to separate the sheets
without tearing the paper. The pressure may be applied by a screw and excentric,
a lever, or in any other well known manner.
In manufacturing envelopes according to this Invention, all the side of the
envelope may be secured by compression, thus the gummed part for securing the
envelope will be dispensed with.
The form of the envelope may be also simplified and the loss of material
attendant upon the necessity for retaining flaps to fold over will be avoided.

page_text: Greater security will also be obtained, as the fastening up of the envelopes may
be effected with apparatus which may vary according to fancy, and thus a letter so
closed when once opened cannot be again closed without the aid of the particular
means used in the first instance.
The paper to form the envelopes is cut into suitably sized strips or pieces, two of
which superposed are passed between a pair of rollers which are striated or grooved
These rollers are
at those parts corresponding to the edges of the paper.
mounted in movable bearings in a suitable framing, and they are geared together
and are driven by a hand wheel on the axle of one of them or in any other
convenient manner.
Instead of cutting the paper into strips or pieces, rolls of paper may be used, in
which case the rollers will be provided with knives to cut the paper according to
the size of envelope required. To close the envelope it will be only necessary to
place the mouth thereof between two striated or grooved surfaces and apply
pressure thereto by means of a lever or its equivalent.
In the same manner bags of paper or other material may be made.
When manufacturing artificial flowers the leaves of paper or other material may
be secured or united together by simple pressure, thus avoiding everything which
may tend to spoil the freshness of appearance of the article manufactured.
The improved mode of securing together sheets of paper may also with advantage
be used for fastening together law and other papers, thus dispensing with the use
of gum, thread, pins, and other fasteners.
It will also be found useful for connecting together, without the use of gum, the
ends of the paper employed for enclosing the roll of tobacco in cigarettes.
In manufacturing cigarettes, the paper is drawn from a roll of a width equal to
the length of the cigarette to be formed. It is then conducted to a cylinder in the
periphery of which are formed four or more semi circular longitudinal indentations.
These indentations are intended to form half moulds, to receive a roll of tobacco
which is brought down from a travelling table by a rocking finger piece in which
the second half of the mould is formed. This finger piece at the same time wraps
the paper round the tobacco, and being provided with a knife edge cuts off the
paper and presses its two edges into a V shaped recess in the periphery of the
cylinder, where they are compressed together. The finger piece is actuated by cam
pieces which are connected with the cylinder, and which strike against the tail of
the finger piece and cause it to rock on its axis. The return of the finger piece to
its normal position after the cam has passed is effected in any convenient manner.
The exact form of the apparatus employed in each case may be considerably varied
so long as the striated or grooved surfaces or their equivalent, by means of which
the securing together of the sheets of paper or other material is effected, are
retained.
