Improvements in and connected with the Manufacture and Con-
struction of Embossed and Corrugated Packing and Lining
Materials.
I, EDWARD SHAILER SEARS of 89 Hopton Road Coventry Park Streatham in
the County of Surrey, Engineer, 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 and construction of embossed and
corrugated paper and similar fibrous materials such as are employed for packings for
bottles and other frangible articles, as linings for carpets, and for other like purposes,
and to apparatus employed in the said manufacture and construction.
According to these Improvements a sheet or roll of paper or similar fibrous material
is corrugated or embossed in such a manner that the corrugations or embossments
are comparatively short in a linear direction, and are arranged in horizontal rows
and, when the corrugated or embossed material is to be used as a bottle packing
or for a similar purpose, in horizontal and vertical rows as hereinafter more fully
described.
In the blank spaces or in some of the blank spaces between the rows of corruga-
tions, creases or semi-incisions may be formed during or after the process of
manufacture in order to enable the material to more readily be bent or to adapt itself
to the form of the article it is designed to protect.
The accompanying drawings illustrate the nature of this Invention and in what
manner the same may be carried into effect.
Fig. 1 is an elevation of a machine by means of which the embossed material
may be constructed and produced; Fig. 2 is a plan of one type of the embossed
material; Fig. 3 is a plan of another type of the material; Fig. 4 is a longitudinal
section of Fig. 2; Fig. 5 is a similar section of Fig. 3, and Fig. 6 is a cross
section of a bottle having the corrugated packing Fig. applied thereto.
It will be seen that the embossed or corrugated material has the embossments or
corrugations in horizontal rows as shewn in Fig. 2 or in vertical rows as shewn in
Fig. 3, or they may both be in horizontal and in vertical rows as may be desired or
be otherwise similarly arranged.
The packing represented in Fig. 2 may be bent around a bottle for example,
parallel with the embossments. To facilitate the bending of the material when
required to protect bottles and other similar articles creases or semi-incisions A may
be made in the material either during or after embossing.
In the drawings the embossments are represented as being alternately in relief
and in intaglio when both sides of the material will be alike, but they may all be in
relief if desired.
The embossed material shown in Fig. 3 is intended for packing purposes. In this
form of the material the blank spaces between the short corrugations prevent the
material from stretching as in the case of ordinary corrugated bottle packing which
has to be pasted or mounted upon a plain backing before it can be used, an
inconvenient necessity which is entirely avoided with this form of packing.
The embossments or corrugations may be produced by means of rollers as repre-
sented in Fig. 1. The rollers are made up of two kinds of rings one with projections C
and the other with corresponding recesses D. These rings are preferably arranged on
their mandrels alternately and so that the projections on the rings of one roller fit into
the corresponding recesses in the rings of the other roller. Alternatively the rings

page_text: may consist of ordinary spur toothed wheels with collars between them, but in this
case the teeth of the wheels are preferably made shorter than usual.
The rollers are carried in sliding bearings of which the lower bearings are
supported and adjusted by screwed shafts working in the nuts formed in the eyes
of the bevel pinions K K. These bevel pinions are rotated for the purpose of
adjusting the lower roller by means of two bevel wheels E E¹ mounted on the shaft F
which passes below the hottoms of the screwed shaft and the pinions. The shaft F may
be rotated by a hand wheel mounted thereon or by means of a worm and worm
wheel G as indicated in the drawings. The independent adjustment of the upper
roller is effected by means of the screws and hand wheels H H.
When the material is desired to be creased or semi-incised as hereinbefore
described, during the process of manufacture, slight grooves may be formed between
the rings forming one of the rollers, and a circular knife or creaser may be fitted in
each corresponding position on the other roller, so that the knives or creasers come
into or over the grooves and form the creases or semi-incisions.
The rollers may be geared together and driven in the ususal manner as is well
understood.
Before passing the paper or other material to be embossed or corrugated between
the rollers, it is first damped so as to enable it to receive and preserve the
impressions.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
(1) In embossed packing and lining material; forming the embossments or
corrugations in short lengths with blank spaces between substantially as hereinbefore
described with reference to the accompanying drawings.
(2) In embossed packing and lining material short corrugations or emboss-
ments formed in rows with creases or semi-incisions between some or all of
the rows substantially as hereinbefore described and as illustrated by the accompanying
drawings.
(3) A corrugated or embossed material suitable for packing bottles and other
frangible articles, for lining carpets and for other analogous purposes, constructed
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
(4) A machine for embossing packing and lining materials, having its rollers
constructed and arranged substantially as herein before described and as illustrated by
the accompanying drawings.
