do hereby declare the nature of this invention to be as follows :-
-
Improvements in scoring or creasing cardboard in order that it may be readily
folded, without weakening the card by partially cutting it through and machinery for
doing the same.
In ordinary scoring machines as at present constructed the card to be operated
upon is passed between a revolving roller and a series of circular knives or discs each
having a single cutting edge the face of the board being partially cut through where
it is required to be folded the fold being made with the score outwards.
In our improvements we use a machine of the ordinary construction as above with
the exception of the circular knives or discs. Each of our circular discs has running
round the periphery two or more ridges separated from each other by a narrow groove,
these ridges are not sharp and do not cut the cardboard but merely crease or indent
it so that it is not weakened.
The object of making two or more creases for each fold is that the fold being
distributed among them there is less liability of the card breaking. The card is folded
with the creases inside.
In order that our invention may be more clearly understood we will proceed to
describe it by aid of the accompanying drawings.
In Figure 1. A. is one of the discs revolving freely on its axis B. and capable of
being adjusted relatively to the roller C. both vertically and longitudinally by suitable
mechanism.
The card being fed between the revolving roller C. and the disc A. two parallel
creases or indentations are formed in it by the ridges D. D. Figures 2. and 5. shew
the creases E. E. in the card as it leaves the machine. Figure 4. shews the form of
the fold with the creases E. E. on the inner surface.
Instead of two ridges on the disc A. three or more may be used in order that the
fold may be more gradually distributed when using a more brittle cardboard.

page_text: LEWIS WYCHERLEY STONE Box Manufacturer of Banbury & EYRE CROWE Engineer,
Banbury, 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 :-
Our invention consists of improvements in scoring or creasing cardboard in order
that it may be readily folded without weakening the card by partially cutting it
through, & machinery for doing the same.
In ordinary scoring machines as at present constructed, the card to be operated
upon is passed between a revolving roller and a series of circular knives or discs each
having a single cutting edge, the face of the board being partially cut through where
it is required to be folded, the fold being made with the score outwards.
In our improvements we use a machine of the ordinary construction as above with
the exception of the circular knives or discs. Each of our circular discs has running
round the periphery two or more ridges separated from each other by a narrow groove,
these ridges are not sharp and do not cut the card but merely crease or indent it, so
that it is not weakened.
The object of making 2 or more creases for each fold is that the fold being
distributed among them there is less liability of the card breaking. The card is
folded with the creases inside.
In order that our invention may be more clearly understood we will proceed to
describe it by aid of the drawings filed with the provisional specification.
In figure 1 A is one of the discs revolving freely on its axis B. and capable of
being adjusted relatively to the roller C. both vertically and longitudinally by suitable
mechanism. The card being fed between the revolving roller C and the disc A two
parallel creases or indentations are formed in it by the ridges D. D.
Figures 2 & 3 shew the creases in the card as it leaves the machine.
Figure 4 shews the form of the fold with the creases E. E. on the inner surface.
Instead of two ridges D. D. on the disc A three or more may be used in order that
the fold may be more gradually distributed when using a more brittle cardboard.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. The circular discs with two or more blunt ridges as described and illustrated.
2. The two or more parallel creases formed on the card without cutting in order
that it may be readily folded along them.
