Improvements in or relating to Means for Supporting Rolls of Paper
to be Supplied to Paper Cutting Machines.
:
I, CARL WEISS, Paper Mill of Bukowetz, near Pilsen, in the Empire of Austria,
Manufacturer, 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;-
-
Machines for cutting up rolls of paper into sheets are, as is well known, generally
combined with stands on which the rolls of paper are supported. A greater or less
number of rolls are employed in order to enable several sheets to be cut at once.
For this reason the above mentioned stands for the paper rolls have been made
hitherto of very large dimensions, and the bearings for the rolls generally arranged
one over another. This hitherto usual construction is subject to the drawback that
the introduction of the heavy paper rolls into the upper bearings is very difficult
and often requires the use of hoists. These stands moreover occupy even with only
a few paper rolls a considerable space compared to the cutting machine itself,
and further the manufacture and machining of the stands is very difficult.
All these drawbacks are obviated by the rotatable frame forming the subject of
the present invention. In the accompanying drawing this new stand or frame is
shown in Fig. 1 in elevation and in Fig. 2 in plan.
The frame consists substantially of two discs or circular frames A which are
keyed on to a shaft C supported in bearings B. On the periphery of the disc A
are arranged symmetrically other bearings D to receive the shafts of the paper
rolls E. In order to enable the latter to be easily introduced into the bearings,
the shaft C is made rotatable which can be effected as may be seen from the drawing
by means of a worm gear F.
When it is desired to place the paper rolls E in their bearings D, it is effected as
follows; Supposing the carriages with the rolls are brought from the right,
then the covers D¹ are removed from, say, the three lowest bearings D on the right
hand side of the discs, and the rolls are placed into the corresponding bearings.
After the covers D₁ have been replaced and fastened on the bearings D, the
discs A are caused to rotate by turning the worm-gear F so that three fresh and
empty bearings occupy the place of the previous ones and so on, till all the rolls
have been inserted. Then the ends of the paper strips of all the rolls are introduced
between the guiding rolls G in the well known manner on to the endless band of
the cutting machine.
The guide-rolls G are supported by cross bars H rotatable about the shaft C and
can be fixed in the desired position by bolting the end of the cross bars opposite the
rollers G on to the discs A.
It will be therefore easily understood that by arranging the paper-rolls in a
circle around the rotatable frame considerable advantages are attained, such
as the easy placing of the paper-rolls in their bearings and the saving of space.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
1. A rotatable frame for supporting rolls of paper to be supplied to paper cutting
machines, characterised by bearings as D) for the shafts of the paper rolls being
arranged in a circle round rotatable discs or circular frames as A, substantially as
described.
2. The combination and arrangement of parts constituting the complete rotatable
frame for supporting rolls of paper to be supplied to paper-cutting machines,
substantially as described and illustrated in the accompanying drawings.
