I, HEINRICH WOLLHEIM, of 344, Wilhelminenstrasse, Loschwitz, near Dresden,
in the Kingdom of Saxony, and German Empire, Managing Director, do hereby
declare the nature of this invention to be as follows:-
This invention relates to vencered boards, the veneers of which are ornamented
by figures of another kind of veneer.
According to known methods such veneers are made by placing the figures cut
out of a veneer into corresponding perforations or cuttings of another veneer and
then glueing both veneers to a suitable wooden board or the like. This method
of manufacture is very troublesome and takes a good deal of time. It requires
highly skilled operators, and the success is never certain, because frequently, the
two veneers do not contract equally during drying, so that spaces are formed
between the figures and outlines of the perforations, or the figures crack or peel
off.
This invention relates to a process or method by which the before mentioned
disadvantages are remedied and which allows of manufacture on a large scale.
In view of the latter object hand labour is superseded by machine work.
The invention is as follows. The veneer, which is to form the ground work.
to be ornamented by figures, is perforated in accordance with the figures to be
applied. Beneath it is placed a veneer of the kind of which the figures are to be
produced. Then both veneers are coated on their undersides with a quickly dry-
ing adhesive material, which becomes liquid when heated and they are placed
on a mill-board, wooden board or other suitable material. The whole combina-
tion is then placed under a press which has a pressing plate of polished steel.
The steel plate is heated and strong pressure exerted by it on the combination of
veneers and board. In consequence the lower veneer is pressed through the
perforations of the upper veneer, so that the upper or ground work veneer and the
lower veneer forming the ornamental figures make an even plane. The adhesive
material becomes solvent under the high temperture of the steel pressing plate,
enters the interstices formed between abutting surfaces and effects a firm and
rigid connection between the several vencers and between them and the board.
The polished surface of the pressing plate produces simultaneously a dull polish
on the veneer.
The pores of the veneer and any cracks that exist in the same are compressed
by the strong pressure exerted by the pressing plate so that the veneer need not
by rubbed down if the surface is to be polished.
The success of the process is the greater the thinner the veneers are.
It is obious that the arrangement of the two vencers one on the other may
be the converse of that herein before described viz.:-the ground work veneer
may be left whole attached to the mill-board or other support, and the figures

page_text: or cut pieces of veneer may be superposed upon and cemented to the ground
work veneer and be pressed thereinto by pressure as hereinbefore described.

A Process for the Manufacture of Ornamented Veneers.
I, HEINRICH WOLLIIEIM, of 344, Wilhelminenstrasse, Loschwitz, near Dresden,
in the Kingdom of Saxony, and German Empire, Managing Director, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to veneered boards the veneers of which are ornamented
by figures of another kind of veneer.
According to known methods such veneers are made by placing the figures cut
out of a vencer into corresponding perforations or cuttings of another veneer and
then glueing both veneers to a suitable wooden board or the like. This method
of manufacture is very troublesome and takes a good deal of time. It requires
highly skilled operators, and the success is never certain, because frequently, the
two veneers do not contract equally during drying, so that spaces are formed
between the figures and outlines of the perforations, or the figures crack or peel
off.
This invention relates to a process or method by which the before mentioned
disadvantages are remedied and which allows of manufacture on a large scale.
In view of the latter object hand labour is superseded by machine work.
The invention is as follows:-The veneer, which is to form the ground work
to be ornamented by figures, is perforated in accordance with the figures to be
applied. Beneath it is placed a veneer of the kind of which the figures are to be
produced. Then both veneers are coated on their undersides with a quickly dry-
ing adhesive material, which becomes liquid when heated, and they are placed
on a mill-board wooden board, or other suitable material. The whole combina-
tion is then placed under a press which has a pressing plate of polished steel.
The steel plate is heated and strong pressure exerted by it on the combination of
veneers and board. In consequence the lower veneer is pressed through the
perforations of the upper veneer, so that the upper or ground work veneer and the
lower veneer forming the ornamental figures make an even plane. The adhesive
material becomes solvent under the high temperature of the steel pressing plate,
enters the interstices formed between abutting surfaces and effects a firm and
rigid connection between the several veneers and between them and the board.
The polished surface of the pressing plate produces simultaneously a dull polish
on the veneer.
The pores of the veneer and any cracks that exist in the same are compressed
by the strong pressure exerted by the pressing plate so that the veneer need not
be rubbed down if the surface is to be polished.
The success of this process is the greater the thinner the veneers are.
It is obvious that the arrangement of the two veneers one on the other may
be the converse of that herein before described viz.;-the ground work veneer
may be left whole and attached to the mill board or other support, and the figured
or cut pieces of vencer may be superposed upon and cemented to the ground
work veneer and be pressed thereinto by pressure as hereinbefore described.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
A process for the manufacture of veneered plates ornamented by figures of
another kind of veneer, consisting of the super-position of a layer of veneer in
figured pattern or shape upon a complete unfigured layer with adhesive material
between the said layers, the mounting of these said layers with adhesive material
upon a foundation or base of card or mill board or wood, and the final treatment
by pressure of the three super-posed layers under a heated plate whereby the
three layers are thoroughly united together and the lower veneer is pressed up
through the perforations or around the figured portions of the upper veneer and
into the same plane thereof substantially as described.
