_JOHN IMRAY, of No. 28, Southampton Buildings, in the County of Middlesex.
IMPROVEMENTS IN APPARATUS FOR CUTTING THE SUPERFLUOUS THREADS OF
LACE, TULLE, AND OTHER FIGURED FABRICS." [A communication from abroad by
Pierre Aimé François Annebic, of St. Pierre-les-Calais, France.]
This Invention relates to apparatus for cutting the superfluous threads used in
weaving lace, tulle, and other figured fabrics, which threads have to be cut and
removed for finishing.
The apparatus for this purpose consists of a framing on which are mounted,
firstly, a beam or cylinder from which the crude fabric is wound, secondly, a cylinder
furnished on its periphery with helical knives or cutters, and, thirdly, a beam or
cylinder on which the fabric is wound after the cutting has been effected, suitable
guide rollers being interposed between these. The cutting cylinder revolves above
an edge over which the fabric is bent as it travels, and a horizontal knife is pre-
sented towards this edge, the cutting being effected by the shearing action of the
revolving helical cutters against the edge of this knife. On starting the operation
on a web of fabric, the end of the web is attached to one end of a sheet the other
end of which is attached to the winding-on beam, and the latter being caused to
revolve, while the cutting cylinder also revolves, the fabric is drawn along between
this cylinder and the edge over which it is bent, having its superfluous threads shorn
by the action of the helical cutters against the stationary blade.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side view of apparatus according to this Invention, Fig. 2 is a part
front view of the shearing cylinder and edge over which the fabric is bent, and
Fig. 3 is a part back view of the same. The fabric is led from the beam D over
the guide roller F and over the edge C under the guide roller G and over H and is
wound on the beam E. In passing over the edge C its superfluous threads are cut
by the action of the shearing roller A and blade B, which may be stiffened by a
vertical plate I. It is of advantage to mount on each side of the edge C small
rollers J and K having pins projecting from their surfaces as in carding rollers,
these serving to keep the fabric operated on from puckering. These rollers J and K
run in bearings projecting down from the table L which at each end is supported
from the side frames.
Having thus described the nature of this Invention, and in what manner the
same is to be performed, as communicated to me by my foreign correspondent,
I claim,―
The use for cutting the superfluous threads from lace, tulle, and other figured
fabrics, of apparatus wherein as it is caused to travel over an edge it is subjected to
shearing action, substantially as herein described.
In witness whereof, I, the said John Imray, have hereunto set my hand and
seal, this Twenty fourth day of May, in the year of our Lord One thousand
eight hundred and eighty.
