Improvements in the Manufacture of Crinkled Paper for Packing and
other Purposes, and in Apparatus therefor.
We, WILLIAM HERBERT LEWER, of 46, Aldersgate Street, Merchant, and
STUART EDWARDS, of 33, Queen's Down Road, Clapton, Paper Maker, both of
London, do hereby declare the nature of this invention to be as follows :—
This invention relates to the manufacture of crinkled paper, that is to say, paper
which being of a certain strength, quality, and thickness, is by and during the
process of manufacture crinkled up transversely to the original direction of its
length so as to increase its thickness, not solidly, but by crinkling or crumpling it
into as it were imperfect or non-continuous and intermittent corrugations, folds, or
sinuses.
The object is to produce simply, economically, and continuously a material well
adapted for packing articles, enveloping bottles and other fragile goods, also for
mural decorations and various other purposes.
To this end we cause the forward end of the sheet of paper in its passage over
one of the ordinary rolls of a paper-making machine to be arrested while the feed
continues, the result being that the paper is suitably crinkled to any required depth
and so thickened, and may then be fed forward to the usual drying rolls, which
latter do not injuriously affect the newly made crinkles.
The apparatus for the purpose consists in the adaptation to or combination with
one of the rolls of a paper-making machine, such as the drying cylinder or the
delivery roll, of a bar of suitable form, section, and rigidity which we call the
"crinkler." This is arranged to run horizontally or thereabouts across the face
of the said roll, and it is mounted in such manner as to be adjustable as to its
distance from the surface of the roll, and to be removable if or when required.
Suitable guide rollers are applied where desirable for directing and regulating the
feed and delivery operations.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Crinkled Paper for Packing and
other Purposes, and in Apparatus therefor.
We, WILLIAM HERBERT LEWER, of 46, Aldersgate Street, Merchant, and
STUART EDWARDS, of 33, Queen's Down Road, Clapton, Paper Maker, both of
London, 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 the manufacture of crinkled paper, that is to say, paper
which being of a certain strength, quality, and thickness, is by and during the
process of manufacture crinkled up transversely to the original direction of its length
so as to increase its thickness, not solidly, but by crinkling or crumpling it into as it
were imperfect or non-continuous and intermittent corrugations, folds, or sinuses.
The object is to produce simply, economically, and continuously a material well
adapted for packing articles, enveloping bottles and other fragile goods, also for
mural decorations, ornamental, and various other purposes.
To this end we cause the forward end of the sheet of paper in its passage over
DO37

page_text: one of the ordinary rolls of a paper making machine to be arrested while the feed
continues, the result being that the paper is suitably crinkled to any required depth
and may then be fed forward to the usual drying rolls, which latter do not injuriously
affect the newly made crinkles.
The apparatus for the purpose consists in the adaptation to or combination with
one of the rolls of a paper making machine such as the drying cylinder or the
delivery roll of a bar of suitable form, section, and rigidity, which we call the
" crinkler."
This is arranged to run horizontally or thereabouts across the face of the said
roll, and it is mounted in such manner as to be adjustable as to its distance from
the surface of the roll, and to be removable if or when required. Suitable guide
rollers are applied where desirable for directing and regulating the feed and
delivery operations.
The accompanying drawing illustrates diagrammatically means for carrying our
invention into effect.
Fig. 1 is a side elevation of the rear end of a paper making machine;
Fig. 2 an isometrical perspective view of same in reversed position having our
invention applied thereto;
Fig. 3 is an elevation of an alternative arrangement.
PP represent the last pair of delivery rolls of the machine and D D¹ the final
drying cylinders; C is the crinkler which consists of a smooth flat bar of suitable
strength and material arranged at right angles or radially to the delivery roll P¹.
It may be mounted as in Figs. 1 and 2 and reudered adjustable as to distance from
the delivery roll P¹ by screwed end pins passing through slots S in bearings B
and provided with nuts T; or the crinkler may be arranged as in Fig. 3 in the
form of a lever pivotted to bracket B at b and resting against the roll P₁ by
gravity, or by tightening up the nuts T of the screwed end pins it may be fixed
as required. The paper A is fed forward in the usual manner in the direction of
the arrows between rolls P and P', and on its forward end meeting the crinkler C
its direct forward course is arrested, causing it to crinkle up somewhat in the
manner indicated, and thence it passes forward over the top of or through an
aperture in the crinkler C, Fig. 3, to the drying rolls D D' which are set at a
suitable distance apart so as not to injure the newly formed crinkles; R is a
receiving table of any suitable kind.
Though we have described certain means of applying our invention we do not
bind ourselves to the arrangements shown, since the crinkler may be fitted to any
suitable roll of the machine and in any convenient manner; but
Having now particularly described, and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improvement in the manufacture of crinkled paper which consists in the
arresting of the direct forward motion of the sheet of paper from any pair of rolls
of a paper making machine whilst the feed continues in such manner as to cause
the sheet to be crinkled in its further forward movement by means of a horizontally
disposed bar or crinkler such as C arranged and adapted to operate substantially in
the manner above set forth.
2. The adaptation to and combination with one of the rolls of a paper making
machine of an adjustable bar of suitable form and rigidity arranged horizontally
or thereabouts and in close proximity thereto, substantially as and for the purposes
hereinabove set forth.
