A communication from abroad by WILHELM LERCH, of wasnei, and MARIE GELINEK,
of Komotau, in the Kingdom of Bohemia, Paper Manufacturers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign Patent
Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in the
County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
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 :-
The textile fabrics, more especially those known as packing cloth and sackcloth,
used hitherto for packing purposes, have many disadvantages, which are entirely
removed by the improved packing cloth, forming the object of the present invention.
The fabrics employed hitherto for the purpose of making packing cloths, sack cloths
etcetera present the disadvantage of becoming easily unravelled. Owing to the large.
spaces left between the individual threads, the fabric allows air, light, and moisture, to
penetrate through it, likewise dust, volatile elements and smell from the goods
contained in the packing pass easily through the latter.
To remedy these disadvantages, a fabric is manufactured which is provided with a
coating of paper pulp for filling up the aforesaid interstices.
In the manufacture of this packing cloth the usual description of sackcloth may be
employed as a ground, and on this is laid by means known in the paper manufacturing
industry, a paper pulp drawn direct from the vat, the fabric having previously
received a coating of some suitable kind of glue (such as a mixture of starch, dextrine,
gluten, size, flour, etc). The fabric coated thus with paper pulp is then dried and may
be glazed between pressing rollers.
The fabric and the paper pulp appear to be intimately united; all interstices between
the threads of the fabric being filled up, and a packing material is produced which
has none of the aforesaid disadvantages of ordinary sackcloth as the threads of the
fabric are covered entirely on one side by the fibre of the paper pulp.

page_text: The covering of fabrics with paper is not new but the novelty of this invention
consists in coating the fabric with paper pulp direct from the vat for the purpose of
removing the porosity of the said fabric, the intermediate layer of glue applied being
in
solely for the object of fixing the coating of pulp more securely to the fabric;
point of fact the coating of the pulp can be laid on and fixed to the fabric without
using any binding medium, although not so effectually as with it.
The fabric coated with paper pulp does not cost much more than the ordinary
sackcloth but it offers over the latter the aforementioned numerous advantages.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is
;
1. The method of manufacturing an impervious packing cloth, sackcloth or the
like, which consists in filling up the interstices left between the threads of the fabric
with paper pulp taken direct from the vat, and intimately connecting (by means
of some binding medium if desired) the said pulp with the fabric, substantially as
described.
2. As a new article of manufacture a fabric coated with paper pulp for packing
purposes substantially as herein described.
