Improvements in Machines for Embossing and otherwise Ornamenting
Circular Sheets or Discs of Paper or similar Material.
I, MOSES HEIMANN, of Melchiorstrasse, Berlin, Germany, do hereby declare the
nature of this invention to be as follows:-
My invention relates to machines for embossing and otherwise ornamenting circular
sheets of paper at or near the edges thereof.
The process heretofore employed for making papers, so called lace papers in disc
shape by means of roller pressure, which paper serves as pastry foils and for wrapping
around bouquets, has the great defect that the pattern must be engraved in the
pressing roller the full size of the paper, whereby the rollers become so expensive and
the pressure required so high that the employment of such rollers is excluded even
with medium sizes. With the machine constructed according to the present invention
the defect referred to is obviated by the use of taper pressing rollers the circumference of
which is only equal to a fraction, say 1, or 1, of the circumference of the paper to
be made as a matter of course the cost of the rollers are diminished to the same
extent.
The employment of such rollers is rendered possible by the perforated or ornamented
edge or rim of the paper consisting of a number corresponding to the size of the paper,
of repetitions of one and the same pattern.
The machine comprises two taper rollers the upper, of which is the engraved steel
roller, whilst the lower serves as a counter roller. The disc-shaped paper leaf to be
provided with a perforated or ornamented rim is clamped centrally between two plates
and is placed with its rim between the two rollers. The lower plate is pivoted upon a
pin while the upper plate is capable of being moved against the lower plate by means
of the screw.
A bent frame which serves as a nut to the screw is of such a size that
it will take the largest discs. The said frame as well as the said pin are secured to a
support by the aid of which the distance of the clamping plate centre from the rollers
can at will be diminished or increased. This accordingly enables large as well as
small papers to be provided with perforated or ornamented rims, only the shafts of the
rollers must always be adjusted in such a manner that the prolongation of their axes
will converge to the clamping plate centre.

page_text: In order to enable such an adjustability of the shafts they can for example be
supported in trunnion bearings which are adjustable in a vertical direction.
According to one construction the trunuions are pivoted in sliding pieces which can
be moved up and down between guide plates by ineans of screws and hand wheels.
For constructive reasons the trunnions for the roller end of the lower shaft are
supported in a different manner. Here they rest in sliding pieces which can be moved
up and down by means of screws in a slot formed in the block. It is evident that by
means of these several adjusting devices the inclination required for any distance of
the clamping plate centre can be readily given to the shafts. The machine may be
driven from the upper shaft.
By the employment of taper rollers and adjustable shafts it is rendered possible to
work papers of the most varying sizes upon the same machine and yet use rollers of a
small diameter.
I may,
if desired simplify the construction of the machine by dispensing with the
adjustability of the lower shaft and making the upper shaft only adjustable as much as
required to enable the paper to be brought between the rollers. The said shafts are
firmly supported in frames. The angle of inclination of the two shafts therefore
always remain the same, and for this reason no support need be used for
adjusting the clamping plates. The clamping plate centre always remains the con-
verging point of the axes of the two shafts, and if papers of different diameters
are to be worked, the rollers must be displaced upon the shafts. For this purpose
either larger or smaller rollers can be used or long cone rollers, upon the periphery
of which the patterns for papers of different sizes are engraved side by side. With
this construction the rollers for larger papers must also be of a larger diameter
than for smaller papers. Still this difference is not considerable and the advantage
is great in comparison with the rollers heretofore known.
If the stamping and cutting of the papers is not to be effected with one and
the same pair of rollers, a second pair of rollers can be employed for one of these
operations, this second pair being supported beside the other. The two pairs of
rollers are here supported with their shafts in such a manner that the axes of all
four shafts converge to one point which is the turning point of the paper, and
thus the centre of the clamping plates. Moreover, the rollers must be upon the
same circles which have the point for their centre.
It is not absolutely necessary to use as an abutment for the pattern roller a
second taper roller, as a taper roller can be used as a cutting roller, and a round
plate as an abutment. Of course, this plate must then be supported by a guide
roller situated below the taper roller on the lower side of the said plate against
the pressure exerted by the taper roller.

I, MOSES HEIMANN, of Melchiorstrasse, Berlin, in the Empire of Germany 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
My invention relates to machines for embossing and otherwise ornamenting circular
sheets of paper at or near the edges thereof.
The process heretofore employed for making so called lace papers in disc shape by means
of roller pressure which paper serves as pastry foils and for wrapping around bouquets,
has the great defect that the pattern must be engraved in the pressing roller the full
size of the paper, whereby the rollers become so expensive and the pressure required
so high that the employment of such rollers is excluded even with medium sizes.
With the machine constructed according to the present invention the defect referred
to is obviated by the use of taper pressing rollers the circumference of which is only
equal to a fraction say, or 4, of the circumference of the paper to be made.
As a matter of course the cost of the rollers are diminished to the same
extent.
The employment of such rollers is rendered possible by the perforated, or orna-
mented edge or rim of the paper consisting of a number, corresponding to the size
of the paper, of repetitions of one and the same pattern.
In the accompanying drawings
Figure 1 shows the machine in side view.
Figure 2 represents a section on the line A. B of Figure 1.
Figure 3 represents a side view of a modified form of machine.
Figures 4, 5, 6 and 7 show details of construction.
The machine comprises two taper rollers a and a' the upper a of which is the
engraved steel roller, whilst the lower serves as a counter roller. The disc shaped paper
leaf to be provided with a perforated or ornamented rim is clamped centrally between
two plates and pl and is placed with its rim between the two rollers a and a¹. The
lower plate p' is pivoted upon a pin s¹ while the upper plate is capable of being moved
A bent frame which serves as a nut
against the lower plate by means of the screw s.
to the screws is of such a size that it will take the largest discs. The said frame ras
well as the said pin s¹ are secured to a support S by the aid of which the distance of
the clamping plate centre from the rollers can at will be diminished or increased. This
accordingly enables large as well as small papers to be provided with perforated or
ornamented rims, only the shafts w and w¹ of the rollers must always be adjusted in
such a manner that the prolongation of their axes will converge to the clamping plate
centre. In order to enable such an adjustability of the shafts w and w they can for
example be supported in trunnion bearings 1, 11 or 12 13 which are adjustable in a

vertical direction. According to the construction shown the trunnions are pivotted
in sliding pieces g, g, g³ which can be moved up and down between guide
plates m, m, m³ m², m³ m³ by means of screws n, n', n³ and hand wheels .
For constructive reasons the trunnions for the roller end of the lower shaft l² are
supported in a different manner. Here they rest in sliding pieces which can be
moved up and down by means of screws n² in a slot formed in the block m². It is
evident that by means of these several adjusting devices the inclination required for any
distance of the clamping plate centre can he readily given to the shafts w and w¹. The
machine may be driven from the upper shaft w.
By the employment of taper rollers and adjustable shafts it is rendered possible to
work papers of the most varying sizes upon the same machine and yet use rollers of a
small diameter.
I may if desired simplify the construction of the machine as shown in Figure 3 by
dispensing with the adjustability of the lower shaft and making the upper shaft w
only adjustable as much as required to enable the paper to be brought between the
rollers. The said shafts are firmly supported in frames m m². The angle of inclina-
tion of the two shafts therefore always remains the same, and for this reason no support
need be used for adjusting the clamping plates p and p¹. The clamping plate centre
always remains the converging point of the axes of the two shafts, and if papers of
different diameters are to be worked the rollers a and b must be displaced upon the
shafts and w. For this purpose either larger or smaller rollers can be used or as
indicated by dotted lines in the drawing-long cone rollers, upon the periphery of which
the patterns for papers of different sizes are engraved side by side. With this con-
struction the rollers for larger papers must also be of a larger diameter than for
smaller papers. Still, this difference is not considerable, and the advantage is great
in comparison with the rollers heretofore known.
If the stamping and cutting of the papers is not to be effected with one and the
same pair of rollers, a second pair of rollers can be employed for one of these opera-
tions, this second pair being supported beside the other in the manner shown in
Figures 6 and 7. The two pairs of rollers a, b, and c, d, are here supported with their
shafts w, w and w² w³ in such a manner that the axes of all four shafts converge to
one point p which is the turning point of the paper, and thus the centre of the clamping
plates. Moreover, the rollers must be upon the same circles which have the point p
for their centre.
It is not absolutely necessary to use as an abutment for the pattern roller a second
taper roller; as a taper roller a as shown in Figures 4 and 5 can be used as a cutting
roller, and a round plate as an abutinent. Of course, this plate must then be
supported by a guide roller situated below the taper roller a on the lower side of the
said plate against the pressure exerted by the taper roller a.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :
For embossing and otherwise ornamenting circular sheets or discs of paper or
similar material the employment of taper rollers on fixed or adjustably supported
shafts w and w¹, the axes of which converge to the centre of the said discs of paper,
substantially as and for the purpose specified.
