Improvements relating to Sticky Fly-paper.
I, WILLIAM THʊм, of the City of Grand Rapids, in the County of Kent and
State of Michigan, U.S.A., 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 certain new and useful improvements in sticky fly
paper, and the invention consists in combination with a strip of paper or web
upon which the sticky material is spread, of a core or roller, said sticky fly paper
having a series of perforations, as hereinafter described, for the purpose of forming
projections outside of the paper which is covered with the sticky material, or
outside of that portion of the paper which unwinds; and the objects of my
invention are, first, to prevent the strip of paper, when unrolled and in position
for use, from coming in contact with adjacent objects; second, to furnish a cheap
and convenient means for preparing the paper for packing and shipment.
These objects I accomplish by means of the mechanism illustrated in the
accompanying drawing, in which
Figure 1 shows a paper strip provided with two lines of perforations which
are adapted to allow that portion of the strip between the lines of perforations,
and which is spread with the sticky material, to be separated and unwound,
while those portions of the prepared strip which lie outside the perforations do
not unwind, but form of themselves disks or spools. The figure shows the strip
as it would appear after it was prepared and a portion of it unrolled or wound
upon a core.
Figure 2 shows the appearance of the paper strips after the same have once been
wound and then unrolled ready for use.
Similar letters refer to similar parts throughout the several views.
A represents the core on which the paper is wound. D represents the central
portion of the web, which is covered with the fly-catching material and which
is adapted to unwind for use. C represents the marginal portions, which when
once wound upon the spool remain wound and form the disks or projections
which are shown in Fig. 2. The marginal portions C are detachably connected
with the central portion D. These I prefer to produce by the perforations H, H.
C¹ represents a strip of adhesive material which may be used for the purpose of
preventing the fly-catching material, which is spread upon D, from escaping.
E represents any suitable means for supporting the unwound strip.
In preparing the strip illustrated in Fig. 1, I provide the strip with two lines
of perforations shown in Fig. 1 by H, H, in order that the central portion of the
strip may be readily separated from the marginal portions. The portion of the
strip within the perforations is covered with the fly-catching material on both
sides, and the marginal portions are covered with any suitable retaining material,
preferably by a material having considerable adhesiveness, so that the marginal
portions will not unwind when the center is unwound for use, thus forming disks
of the marginal portions which are still unwound, and leaving the unwound

page_text: portions covered with the sticky material on both sides from edge to edge. The
confining material across the end of the strip of paper, shown by C', preferably
does not have as much adhesiveness as the material which forms the two sides or
margins of the strip. When thus constructed the parts outside of the perforations,
having the configurating border, will present the appearance shown in Fig. 2
after the web is unwound for use. The end of the paper may be wound a
short distance and the rounds glued together for the purpose of forming the
cylinder or core, if desired. It will be understood that when the paper strip is
provided with the perforations the paper is all wound together, Fig. 1 showing
a small portion of one end of the paper strip wound, when it presents the appear-
ance of an ordinary roll of paper, but as the sticky material is unwound, the
marginal portions remaining wound, the ends or disks appear as illustrated in
Fig. 2. I have described the spool or projecting disks, but do not wish to confine
my invention to a round form, as it will be evident that the web may be wound
on a round, flat, rectangular, or other shaped core with equal facility and like
results.
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 of sticky fly-paper formed of a web or strip of suitable material
having its central portion covered with the fly-catching compound, its margin
covered by a retaining material, the central portion separably connected to the
marginal portions and adapted to be unrolled without unwinding said marginal
portion, substantially as described.
