COMPLETE SPECIFICATION.
Apparatus for Stamping Out Cards, Cardboard, and the like.
I, KARL KRAUSE, of 59, Zweinaundorferstrasse, Leipzig, Germany, Machine Manu-
facturer, 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:
When cartons (blanks of paste-board for paper-boxes), cards, etc., have to be stainped
or cut out with bevelled edges and rounded corners, pressing plates are usually em-
ployed, the side surfaces of which are bevelled for the purpose of guiding the cutters
which are suspended on a knife head arranged above, so that when the pressing head
descends and the pressing plate bears upon the cardboard, the cutters move or travel
This
along the side of the same and cut out the cardboard in the desired manner.
apparatus, however, is inefficient when the corners of the cartons have to be rounded
as well as bevelled, the rounding-off being subsequently effected by a special knife
head and a second pressing or stamping. By this invention the rounding off of the
corners and simultaneous bevelling of the edges is rendered possible, this being
effected as follows:-The cutters for the corners as well as those for the sides are
attached to the same cutter head, and in such a manner that the corner cutters may
be set with their cutting edges in advance of those for the sides, so that when
pressure is applied to the pressing head the corners are first cut and immediately
thereafter the edges of the cartons. In a modification this sequence may be re-
versed.
Referring to the annexed drawings,
Figure 1 is an elevation, and
Figure 2 is a plan view of my apparatus.
.
The side cutters M¹ to M are attached to the knife head by means of spring
rods F to F and the corner cutters M5 to M8 by means of springs Fs to Fs. The
whole of the eight cutters rest on the oblique surfaces of the pressure plate P. When
the knife or cutter head descends, the eight knives, after the pressure plate P has
descended on to the cardboard, slide along the oblique surfaces and cut out the
cardboard. The cutting edges of the cutters M to M8 are set in advance of those of
the side cutters M¹ to M', so that they cut sooner than the latter. In this way it is
possible to stamp or cut out cardboard (cards) with oblique or bevelled edges and
rounded corners by means of one pressing operation. In a modification, I may
arrange the cutting edges of the cutters M³ to Ms for the rounding off of the corners,
behind or rearward of those of the cutters M¹ to M* for the edges, and thus when
the plate P descends, the edges will be cut first and the corners immediately
fterwards
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. Apparatus for stamping out cardboard, cards and the like, with oblique or
bevelled edges and rounded off corners simultaneously, in which the cutters M¹ to Ms
outter head D are guided on the oblique side surface of a pressing

page_text: plate P, the distinguishing feature being that the cutting edges of the cutters M5 to M³
for the corners are in front of those M¹ to M5 for the edges, in order that when the
pressing plate descends, the corners should first be cut out and thereupon the edges,
the one directly after the other, substantially as described.
2. A form of the apparatus for stamping out cardboard, cards or the like according
to Claim 1, the distinguishing feature being that the cutting edges of the
cutters M5 to M8 for the rounding off of the corners are behind those of
the cutters M to M for the edges, so that, when the pressing plate descends, the
edges are first cut and thereupon the corners, the one directly after the other,
substantially as above described.
