COMPLETE SPECIFICATION.
An Improved Package Roll for Holding and Applying Metallic Leaf.
I, WALTER HAMILTON COE, of No. 166, Cranston Street, Providence, Rhode
Island, United States of America, 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; -
In the employment of package-rolls for holding and applying metallic leaf
for out-door decoration and especially in rolls of considerable width, it is desirable
to have the film of metallic leaf slightly held to the surface of the supporting
strip, but when attached, as heretofore, by the employment of a coating of wax
or similar adhesive material applied to the entire surface at one side of the strip,
it is found in practice that the variable atmospheric conditions which occur during
the process of winding the package-rolls in the factory, may cause an injurious
change in the quantity of adhesive material deposited upon the strip, whereby the
film will not be suitably attached thereto for transfer to the out-door surfaces to
be decorated, being either too strongly or too lightly attached to the strip. A
slight change in the consistency of the wax, due to commercial adulteration will
also serve to cause a great change in its adhesive quality. I have been able to
overcome these defects, and to employ wax of varying grades as the attaching material
in the formation of the package-rolls, without injuriously affecting the attachment
of the metallic leaf to the supporting strip, and my invention consists in depositing
the wax upon the supporting strip in a series of longitudinal lines, with interven-
ing vacant spaces in which the film will not be attached to the strip, I am thus
enabled to connect the film to the supporting strip at all required portions of its
width for practical purposes in out-door work with the employment of a much less
quantity of wax or other adhesive material, and also to provide longitudinal
unattached spaces for the entrance of air longitudinally of the film to facilitate
the withdrawal of the film from the strip, and its transference to the surface to be
decorated.
In the accompanying drawings:
Fig. 1 represents an end view of a package-roll composed of metallic leaf, and
a supporting strip of paper, the metallic leaf being indicated by the dotted line.
Fig. 2 represents a side view of the package-roll, with the supporting strip
partially unwound, showing the surface of the unwound film of metallic leaf, and
the series of longitudinal lines of wax coating arranged upon the surface of the
unwound supporting strip.
In the drawing, A represents the improved package-roll of metallic leaf which
is adapted for the ready transfer of the metallic leaf therein contained, to the sur-
face to be decorated, B is the core upon which the film of metallic leaf C, and the
supporting paper strip D are wound, the said core being provided with the axial
perforation C, by means of which it may be held for rotation, while the strip and
film are being unwound from the package-roll. The paper strip D, is provided at

one side with a series of parallel longitudinal lines of wax a a a, deposited upon
the surface of the strip, so as to cause the adhesion of the metallic leaf not through-
out its whole extent, but with the intervening spaces 6 b, of non-attachment to the
strip, whereby the air will be readily allowed to enter in a longitudinal direction
between the film and strip at the spaces bb, when the film is being deposited
therefrom upon the surface to be decorated. My improvement is therefore
especially adapted for employment in package-rolls of the wider widths, for out-
door decoration, where the film of metallic leaf upon the surface of the strip is
liable to be affected by the action of the wind.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
A package-roll of metallic leaf, consisting of a wound supporting strip, and
a film of metallic leaf wound therewith, the said supporting strip being provided
with a series of longitudinally directed lines of adhesive material deposited upon
one of its sides with non-adherent spaces between them, substantially as described.
