Improvements relating to the Manufacture of Cord for Trimmings,
Lace-work, and the like.
We, HENRI FRANÇOIS MOREAU, and LÉON MOREAU, both of 21 Boulevard
Poissonnière, Paris, in the Republic of France, 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 :-
Our invention relates to the manufacture of cord for trimmings, lace-work and
the like.
Up to the present time such cord, consisting of a core of cotton simply covered
with a silk thread wound spirally, has presented the serious inconvenience that when
it is cut the silk which surrounds the core of cotton unwinds and lets the cotton
appear for a certain length.
This inconvenience, by reason of the bad effect produced, militates against the
use of such cord in lace-work, especially in Chantilly lace-work, which is manu-
factured in pieces and sold like all fabrics which are cut to any length desired by
the buyer.
According to our said invention we manufacture cord having a silk cover which
adheres firmly to the cotton core and forms one piece as it were with this core,
so that the cord may be cut without causing the silk to unwind or the cotton to
appear.
Cord of this kind will be of very great service for trimming purposes and
particularly in the case of Chantilly lace-work, which is manufactured in pieces.
In order to explain how this improved cord with adherent silk is produced we will
now proceed to give a complete description of our process.
The core composed of a greater or smaller number of cotton threads, which may
be either simple or twisted together, and used in the form of skeins or otherwise, is
coated with an adhesive substance of any kind. The coating is effected in any
suitable manner by hand or by mechanical means either by immersion or by passage
through a tub or other receptacle containing the adhesive substance in a liquid or
fluid state. If desired we may use any other process by which the same final result
is achieved without departing from the scope of our invention.
When the core has been coated it is dried either in a stove or in the open air or
by the aid of a cold or hot current of air. Under these circumstances the coated
core presents the ordinary form and may be put in the machine to be surrounded
with a silk thread which is wound spirally by any of the well-known means so that
its convolutions join each other.
When the core has thus been covered with silk, that is to say when the cord has
been formed, it is subjected to the action of a humid temperature, the immediate
effect of which is to soften the adhesive substance and to cause the pasting of the
silk upon the cotton threads so as to unite the silk and cotton which will not
afterwards be separated when the cord is cut. The softening of the adhesive
substance may be obtained by placing the cord in a closed box and injecting
steam into the latter, but it is understood that we may effect it in any other suitable
manner.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
First. In the manufacture of cord for trimmings, lace-work and the like the
improvement which consists in pasting upon the core of cotton the silk which
surrounds it and serves as a cover, the said pasting taking place by coating the core

page_text: with an adhesive substance, and then drying it in order to wind the silk thread
spirally upon the same and by subsequently softening the said adhesive substance to
effect the adhesion of the silk cover to the cotton core, for the purpose of preventing
the silk from unwinding and allowing the cotton to appear when the cord is cut,
substantially as hereinbefore described.
Second. As a new article of manufacture a cord having a silk cover intimately
united with the cotton core, which union of the core and cover may be obtained
either by the process of pasting specified in the first claim or by any other process,
and irrespective of the nature of the adhesive substance employed, a distinctive
feature of the said cord being that it has a cover which is not liable to unwind or
allow the cotton which serves as a core to appear, substantially as herein before
described.
