1, ALEXANDER DAVIDSON, of Paul's Pier Wharf, 23 Upper Thames Street,
in the City of London, Paper Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus for striping wrapping papers and paper bags
with one or several stripes of one or several colours; by its use a very great saving
may be effected over the existing methods of performing this operation.
The apparatus can either be attached to the paper making machine or the paper
bag making machine or erected separately.
The apparatus consists of one or more rolls according to the number of colours
required, running in troughs containing liquid colours.
These rolls have raised rings upon them and on the top of each of these rolls
there runs a roll jacketted with india rubber or other elastic substance.
The rings may either be plain and of uniform width or of a more or less
ornamental contour.
The paper is passed between the two rollers forming a pair and the raised rings
serve to apply the colour. Afterwards the paper may be passed over a drying
cylinder or cylinders.

COMPLETE SPECIFICATION.
Apparatus for Striping Wrapping Papers and Paper Bags.
I, ALEXANDER DAVIDSON of Paul's Pier Wharf, 23 Upper Thames Street, in
the City of London, Paper 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 :-
This invention relates to apparatus for striping, wrapping papers and paper bags
with one or several stripes of one or several colours, by its use a very great saving
may be effected over the existing methods of performing this operation.
The annexed drawing shows a machine in accordance with my invention;
Figure 1 is a plan with parts removed and Figure 2 is a vertical section.
The apparatus can either be attached to the paper making machine or the paper
bag making machine or erected separately or it may be otherwise used as for
example as an adjunct to a paper cutting machine.
The apparatus consists of one or more rolls aa² according to the number of
colours required, running in troughs & containing liquid colours.
These rolls are of metal and have raised rings upon them and on the top of
each of these rells there runs a roll e jacketted with india rubber or other
elastic substance.
The rings may either be plain and of uniform width or of a more or less
ornamental contour.
dd are scrapers or "doctors," their edges are notched and fitted to the ribs on
the rolls. The doctors are so set as to remove the superfluous ink from the rolls
leaving however sufficient upon the ridges of the rolls to stain the paper in the
manner desired.
The two rolls are driven at the same surface speed by belts and pulleys as the
Pains 8.11

page_text: drawing indicates and the speed is if necessary adjusted to suit the paper making
machine or other machine in unison with which the striping apparatus is required
to work.
The paper is passed either from a reel or from the paper making or other
machine between the two rollers forming a pair and the raised rings serve to apply
the colour. Afterwards the paper may be passed over a drying cylinder or
cylinders.
In some cases it may be required to stripe paper bags already made, or paper
already cut up into sheets; this may be done by providing guiding tapes to convey
the bags or sheets through the machine.
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 :-
The apparatus herein described for striping wrapping papers and paper bags.
