Improvements in Machines for Moulding, Decorating, Perforating,
and Cutting Dough.
I, JOHANN AEGETER of No. Kleinergrasbrook, Hamburg, Germany, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machines for moulding, decorating,
perforating and severing or cutting dough, and has for its object to replace the
cut-out machines such as are employed more particularly in the manufacture of
cakes and biscuits. The machine provided with my present improvements is
distinguished from the machine hitherto in use by the following advantages:-It
provides for a continuous working: it produces, without waste, any desired, and
even perforated, form of baking; it automatically effects the discharge of the
ready made pieces of dough into the pans at an ample distance from each other, so
that the baking can be perfectly executed; and, finally, it provides for the baking
pans being greased automatically.
To carry this invention into practice, I provide at the front end of the machine a
suitable table or plate designed for laying the duly prepared dough on, and which
may be pushed, if desired, between a pair of rollers serving to roll out the dough to
a layer of uniform thickness, and which is afterwards conveyed to a second pair of
rollers which are hereinafter called the moulding rollers. The upper one of these
à engraved according to the conformation or decoration which the pastry shall
receive. The lower roller is, as usual, smooth and merely designed to act as a kind
of counter roller. The dough-pieces produced with the aid of these moulding
rollers, are conveyed either directly, or by means of an endless band running about
and being actuated by the lower of the said moulding rollers, to an adjustable apron
the first part of which travels horizontally and, the second, obliquely so as to direct
the separate dough-pieces into the baking pans, which are suitably arranged on a
second apron, which is moved with a corresponding speed beneath the aforesaid
apron. Both aprons are led over suitable rollers which are driven by suitable
gearing from the main driving shaft from which also the feeding and moulding
rollers are driven. Suitable means are provided for stretching the aprons, if
required.
If, instead of separate dough pieces, continuous pieces are to be produced by the
moulding rollers, such pieces may be conducted through the medium of the said
first apron beneath a rotating cutter having a number of radially arranged knives
which are designed to sever the said pieces transversely. The dough pieces so
obtained are then forwarded and treated in the same manner as above mentioned
with regard to the dough pieces directly formed by the said moulding rollers.
The said rotating cutter is, by means of intermediate gearing, driven from the main
driving shaft, to impart to it a corresponding motion with that of the moulding
rollers.
In some cases, I also provide, in contact with the said endless band and close to
the moulding rollers, a roller dipping into a receptacle containing a suitable fat,
which is adapted to grease the said endless band, in order to prevent the dough
pieces sticking to the band and at the same time to facilitate the delivering of them
from the engraved moulding roller. Consequently, the greasing of the baking pans,
as hitherto effected, may be entirely dispensed with.

Improvements in Machines for Moulding, Decorating, Perforating,
and Cutting Dough.
I, JOHANN AEGETER of
declare the nature of this
performed, to be particularly
statement:-
Kleinergrasbrook, Hamburg, Germany, do hereby
invention, and in what manner the same is to be
described and ascertained in and by the following
My invention relates to improvements in machines for moulding, decorating,
perforating and severing or cutting dough, and has for its object to replace the
cut-out machines such as are employed more particularly in the manufacture of
cakes and biscuits. The machine provided with my present invention is distinguished
from the machines hitherto in use by the following advantages:-It provides for a
continuous working; it produces, without waste, any desired, and even perforated,
form of baking; it automatically effects the discharge of the ready made pieces of
dough into the pans at an ample distance from each other, so that the baking can
be perfectly executed; and, finally, it admits the greasing of the baking pans to be
entirely dispensed with.
In order to make my invention more clearly understood I will proceed to describe
the same with reference to accompanying drawing, in which
Figure 1 is a sectional side elevation:
Figure 2, an end view, some parts being taken off for the sake of clearness, and
Figure 3, a top view, partly in section, of a machine made in accordance with my
present invention.
At the front end of the machine, the frame of which is formed of the standards A
and A', I provide a suitable plate or table T designed for laying the duly prepared
dough on, and which may be pushed either by hand or automatically between a
pair of rollers a, b serving to roll out the dough to a layer of uniform thickness and
which is afterwards conveyed to a second pair of rollers n, m which are hereinafter
called the moulding rollers. The upper one (n) of these rollers is engraved according
to the formation or decoration which the pastry shall receive, whilst the lower
roller (m) is, as usual, smooth and merely designed to act as a kind of counter
roller. The dough-pieces produced with the aid of these moulding rollers are,
preferably, conveyed to an adjustable apron L the first part of which, leading over
a guide bar c contiguous to the lower one of the moulding rollers, travels horizontally
and, the second, obliquely, so as to direct the separate dough-pieces into the usual
baking pans, which are suitably arranged on a second apron P which is moved with
a corresponding speed beneath the aforesaid apron L-see Figure 1. The apron L
is led over suitable guide boards c, c' and rollers d, d', d² and e, of which the latter
is designed to impart the required travelling motion to the apron. The lower
apron P however is only guided by the rollers ƒ and g of which the former serves
as driving roller while the latter is journalled in a pair of movable bearings i
which are guided by brackets attached to the standards A, A' of the machine in
order to admit the stretching of the apron, if required. For the same purpose
similar bearings carrying the pivots at the extremities of the guide board c'
of the apron L, are adapted to slide within the guides ' supported by the
standards A A¹. To this effect, set screws k and k¹ are provided for moving the
bearings and i¹, respectively, in their guides h and . From this arrangement it
will be seen that the dough-pieces on the apron L are caused to drop by rows into
correspondingly arranged pans (not shewn in the drawing) on the apron P, as soon
as they arrive at the outer edge of the guide board c¹ of the apron L, so that the
dough-pieces may be baked in the usual manner. The baking-pans put on the
apron P from the end of the machine at fare carried along beneath the apron L
and may be taken off from the former alongside of the machine.
If, instead of separate dough-pieces, continuous pieces are to be produced by the

page_text: moulding roller, such pieces may be conducted through the medium of the apron L
beneath a rotating cutter r having a number of radially arranged knives which are
designed to sever the said pieces transversally. The dough-pieces so obtained are
then forwarded and treated in the same manner as above mentioned with regard to
the dough-pieces directly formed by the said moulding rollers.
Motion is imparted to the several parts of the machine from the main driving
shaft carrying a loose and fast pulley y, y'. On this shaft is keyed a pinion p
and a belt pulley z, the former meshing with a wheel m' on the shaft of the roller m,
the latter being connected through a belt z' with the pulley z² on the intermediate
shaft 23, which serves to transmit motion by means of the cone-pulleys 20 and 2*, a
belt and the gearing, on to the shaft f¹ of the driving roller f of the apron P.
To the one end of the shaft is fastened a drum f2designed to actuate the
apron L through the medium of the belt f³ and of the drum e² keyed on the driving
shaft e¹ of the roller e, thus making the travelling motion of the apron L dependent
upon that of the apron P. But in order to compensate certain irregularities in the
motion of the one apron in relation to the other or to easily proportionate the speed
of one apron to the other, I make the drums e² and f² conical in opposite direction,
so that on shifting the belt f³ accordingly, the speed of the one apron may be made
more or less in relation to that of the other.
At the opposite end of the shaft e¹, a step pulley e³ is provided corresponding
with a step pulley 2 on the shaft of the rotating cutter which is thus actuated
through the medium of a belt or rope 3 from the shaft e¹ of the driving roller of
the apron L.
In conformity with the motion of the aprons L and P, the activity of the
moulding rollers m, n as well as that of the rollers a, b for rolling out the dough,
are made depending upon the speed of the main driving shaft x, since the wheel m²
keyed on to the end of the shaft of the moulding roller m opposite the wheel m',
meshes through the medium of an intermediate wheel m³, with the wheel b¹ on the
shaft of the roller b, and the roller a is made to partake of the motion of the roller b
in consequence of a pair of wheels, engaging one with the other, fastened to the
other end of their shafts. The intermediate wheel m³ is designed to admit the
wheel on the shaft of the roller to be exchanged by other wheels of different
size in order to regulate the speed of the rolling-out rollers a, b in proportion to the
capacity of the moulding rollers m, n; and for this purpose the wheel m³ is carried
by a traverses being at its upper end suspended by the shaft of the moulding
roller m and at its lower end adjustably connected to a slotted brackets of the
standard A. Consequently, the position of the traverse s may be easily altered
according to the size of the wheels employed on the shaft of the roller b.
Whenever it is desired to feed the dough automatically to the rollers a, b, an
endless band t passing between and being actuated by the rollers a, b is provided.
This band is fed over the guide-board contiguous to the moulding roller m,
the roller beneath the roller b and the front guiding roller 3, the latter
being journalled by adjustable bearings carried by suitable brackets * of the
standards A, A', in order to admit stretching of the band t, if required. In contact
with the moulding rollers, rotating brushes such as land o may be provided, which
are adapted to clean the said rollers and to grease the same in order to facilitate
the delivering of the dough-pieces from the engraved moulding roller and at the
same time to prevent them sticking to the lower moulding roller and to the apron.
Consequently, the greasing of the baking pans, as hitherto effected, may be entirely
dispensed with.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a machine for moulding, decorating, perforating and cutting dough, the
combination of a pair of moulding rollers, such as m, n, an apron such as L, the
first part of which travels horizontally and the second part obliquely, and a second
