WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE MANUFACTURE OF
THREAD OR YARN WITH A PILE OR SHAGGY SURFACE." [A communication from
abroad by the Company trading as Harmel Brothers, of Val-des-Bois, France,
Spinners.]
The object of this Invention is the production of a new kind of compound thread
or yarn, which is so made that it presents a rough, shaggy, or brushy appearance.
The said thread or yarn has a series of projecting pieces or tufts, which appear to
be a number of small cut ends of thread fixed transversely upon one or several
longitudinal threads, as in chenille, but this is only in appearance, the said pro-
jecting pieces being in reality produced by continuous threads grouped in this
peculiar manner around the thread, which serves as the support or centre of tho
compound thread or yarn. Therefore the characteristic peculiarity of the said
thread or yarn consists in its rough or shaggy appearance, which seems to be in
contradiction to the manner in which it is really made, that is to say, upon tho
principle of continuity in the separate threads which compose the whole.
In order to obtain the above described special effects I may make use of several
processes or methods, and the process which is hereinafter described as an example
comprises two operations which are carried into practice upon a spinning frame or
upon a twisting or twining frame.
In the first place the thread which is to form the support or centre is led between
delivering cylinders to a spindle, and during its passage between these parts it receives
the threads which are designed to give the aforesaid shaggy or rough appear-
ance. There may be any number of the last named threads, which are led between
two cylinders, to which is imparted a higher speed than that of the first named
cylinders, so that these threads will be acted upon in such a manner as to form the
undulations and projections upon the centre thread. The threads forming the pro-
jections or shaggy portion come down to the centre thread from the cylinders above
the latter thread, and become attached to the same at intervals, and as they have
been twisted before the new rotation which is given to them they are forced to
twine around themselves, and to form portions making small pieces, which are in

different colors they will give a multi-coloured appearance to the rough portion.
After the above described operations have been effected it remains to fix the
rough or shaggy threads in the positions where they are deposited on the centre
thread, and this is the object of the aforesaid second operation, which consists in
re-twisting the compound thread or yarn coming from the frame with another
single thread which binds the spirals into projecting or shaggy ends or tufts, and thus
consolidates the elements of the compound thread or yarn.
The said shaggy or brushy thread or yarn may be made of all textile materials;
for example, wool, cotton, silk, flax, hemp, and the like, the same materials being
employed for the whole or part of the threads forming the shaggy portion or the
centre or supporting threads. Moreover the threads may all be of the same color
or of different colors; in fact, the special effects may be infinitely varied, the
compound thread or yarn in all cases retaining its rough, shaggy, or brushy
appearance.
