and similar Fabrics or Materials.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
My invention consists in a sheet or roll of paper, paper pulp or analogous material
having broken corrugations or alternate depressions and elevations upon both sides of
the sheet. These corrugations are placed in series both lengthwise and crosswise the
sheet. The paper between said corrugations is shirred, fulled or wrinkled.
In the accompanying drawings Fig. 1. represents a portion of my corrugated paper.
Fig. 2 is a sectional view of the same on the line of Fig. 1. Fig. 3 is a
sectional view of a piece of embossed paper and is here presented to illustrate the
difference between paper on which protuberances are formed by embossing and paper
corrugated in accordance with my invention. Similar letters of reference indicate like
parts.
Corrugated paper as at present known is made with the corrugations or flutes
extending transversely the whole width of the paper and the paper itself is simply
bent or folded or as sometimes termed fluted or quilled. This sort of corrugated
paper is often employed for bottle packing, carpet lining etc. but in order to fit it for
use it is necessary to re-enforce one side with a flat sheet of paper pasted on, so as to
prevent the corrugations or flutes flattening out.
"
Embossed paper on the other hand is not made by folding, fluting or bending the
paper but by forcing certain portions of it into matrices or dies. The portions thus
pressed into shape are stretched and hence reduced in thickness.
My improved material is made by partial corrugation, that is to say
short corruga-
tions not extending across its entire width are formed upon it so that protuberances

where they occur is reduced in length. Consequently all the material adjacent to said
corrugations becomes shirred fulled or wrinkled-and the result is the fabric illustrated
in Figs. 1 and 2.
Referring more particularly to Fig. 2 it will be seen that the material is not thinned
or reduced anywise in thickness at the corrugations and by comparing Fig. 2 with
Fig. 3, which last figure shows a section of a piece of embossed paper, the difference
in thickness of the material at the protuberances will readily be apparent. In
Fig. 2 A A represents the general plane of the fabric. B are corrugations or
protuberances on one side and corrugations or protuberances on the other side. D is
the shirred fulled or wrinkled portion.
A fabric thus formed has great elasticity, abundant stiffness to retain its shape in
use, and requires no re-enforcing sheet. It is especially adapted to be placed under
carpets to serve as lining, and for the packing of bottles or other fragile articles. The
elevations and depressions occuf alternately in regular order lengthwise crosswise and
oblequely on both sides of the sheet, which is thus not only strengthened and adapted
mechanically for the special purposes for which it is designed but is rendered novel
and attractive in appearance, fitting it for the production of a great variety of fancy
articles, wall decoration &c.
There are many fabrics which may be made into sheets and corrugated as above
described, but I prefer paper, straw board, wood pulp or similar material. Corruga-
tion of the sheet is effected in any convenient manner preferably by intermeshing
rollers having surfaces suitably configured.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
Foreign Correspondent I declare that what I claim is :-
1. A fabric having a fulled, shirred or wrinkled surface or short corrugations
extending above and below said surface.
2. A fabric having a fulled, shirred or wrinkled surface and short corrugations
disposed and arranged as described and extending above and below said surface.
