PROVISIONAL SPECIFICATION.
An Improved Corrugated Strip for the Protection of the Edges of
Reels of Paper and the like.
We, CHARLES JOHN SMART of Ely Paper Mills, Cardiff, in the County of
Glamorgan, Paper Manufacturer, and FREDERICK CHARLES GWYNNE of the
Breckonshire Millboard Company, Crickhowell in the County of Brecon, Mill-
board Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a new method of protecting the edges
of cylindrical rolls of paper, or any kind of bale of paper of whatsoever shape.
Hitherto unprotected rolls of paper such as the reels employed in the production
of newspapers and the like have been subject to great damage at the outside edges,
through insufficient protection. Various attempts have been made to provide a
protecting edge, such as wrapping several thicknesses of paper around; and iron
hoops have also been tried.
According to our invention, we employ a strip of millboard or its equivalent of
any convenient length. This strip is corrugated for about half its width and for
its entire length upon one edge, the other edge remaining plain. The strip is also
bent down the centre line at a right-angle and a longitudinal corrugated ridge is
caused to project slightly along the centre line. The angle piece thus formed is
also bent into a curve, so that it may the more readily lie against the outer
diameter of the reel of paper, the corrugated part lying upon the flat face. The
corrugations overlap each other when the projecting angle piece is fixed in position.
The thickness of the material forming the corrugation being threefold (more or
less), where each overlap takes place, causes the flat face of the reel to stand clear
of the ground to the extent of the three thicknesses, so protecting the entire face
from injury. The projecting ridge before mentioned also assists in affording
protection. The strips may be made of any suitable material and may be
interleaved with suitable strengthening material either in combination with any
product made from paper-stock or not.
We may also use thin strips of metal, corrugated and bent as described. In
applying this invention to the protection of large or small reels of paper, we lay
the corrugated angle strip around the edges and then wrap the reel in the outside
packing paper in the usual way, the outside packing and the rope binding keeping
the corrugated strips in position.
One great advantage conferred by this invention on its user, is that very much
less outside packing is required, as the corrugated angle strips perfectly protect
the edges of the paper.

Reels of Paper and the like.
We, CHARLES JOHN SMART of Ely Paper Mills, Cardiff, in the County of
Glamorgan, Paper Manufacturer, and FREDERICK CHARLES GWYNNE of the
Breckonshire Millboard Company, Crickhowell, in the County of Brecon, Mill-
board 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 :-
The object of this invention is to provide a new and improved means for pro-
tecting the edges of reels of paper or of bales of paper of any shape. Hitherto
the unprotected edges of reels of paper such as those used with newspaper printing
machines, have been subject to a considerable amount of injury in transit from the
mills to the machine room. Various attempts have been made to obviate such
injury, by providing a protecting device, such device taking the form, among
others, of several thicknesses of paper wrapped around the reel or of iron hoops.
According to the present invention, we make use of a strip of millboard or
equivalent material. This strip is corrugated for about half the width of the
entire length and bent through a right angle along the centre of the strip, and at
this angle, a projecting ridge may be, and is advantageously, formed. When the
angled strip is required to protect the edges of a reel of paper, it is bent to a curve
in order that it may the more readily fit snugly up to the side and end of the reel
over the corner or solid angle thereof.
Referring to the accompanying drawings,
Figure is a perspective view of a reel of paper to which our invention has been
applied.
Figure 2 is a perspective view of a piece of angled strip bent to a curve.
Figures 3 and 4 are details of the corrugations.
A is the reel, e.g., of paper. B is the plain half or web of the strip and C, the
corrugated half or web, the two bent at a right angle with each other. Our
invention does not restrict us to the use of any particular material for we may use
any that is suitable to the purpose of the invention-millboard, as above mentioned,
or millboard with a strengthening layer incorporated with it, or metal. D is the
ridge above referred to. It is an externally projecting one, the direction of pro-
jection being in continuation of the width of the plain web B, so that when the strip
is fixed on the reel, the ridge shall project beyond the end thereof and not out-
wards from the side. We prefer that the ridge shall be convex iu cross section, as
shewn.
E, E are the corrugations. They stand at right angles to the length of the
strip, and are therefore radial to the reel when the strip is fitted on to the latter.
After this has been done, they are pressed down over each other into the position
shewn in Figure 4, so that a single strip will provide a protecting device consisting
of three thicknesses of material over the edges of the paper in the reel. The
idge D will also serve as an additional protecting device. The corrugations
themselves may be of any suitable shape.
In applying the invention to the protection of the edges of paper in a reel, we
lay an angled strip around each end of the reel over each corner or solid angle, as
illustrated in Figure 1, ie, with the plain web to the side and the corrugated
one over the end, and then wrap the reel up in the outside packing paper in the
usual way, such packing and the rope binding sufficing to keep the strips in their
place.

page_text: One of the great advantages conferred by the present invention on its user, is
the great consequent economy in outside packing paper.
The drawings illustrate the application of our invention to reels the edges of
which are exposed to injury, but it must be understood that our improved device
is applicable also to the protection of the edges of paper and similar material
in bale.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
1. The angled strip corrugated across one half or web thereof, as set forth.
2. The combination with an angled strip, of corrugations across one half or web
of it and a ridge projecting outwardly from the angle, as set forth.
