Improvements relating to the Method and Machinery for Partial or.
Complete Dyeing of Combing Ribbons or Slivers or the like.
·I, Reginald HadDAN, of the Firm of Herbert Haddan and Co., of 18, Bucking-
ham Street, Strand, London, Patent Agent, do hereby declare the nature of this
invention a communication to me from abroad by Felix Desurmont, of Tourcoing;
in the Republic of France Carder, and in what manner the same is to be performed
to be particularly described in and by the following statement:―
This invention relates to a machine by means of which one can either partially
dye in the usual dyeing baths the combing ribbons or slivers intended for the
making of mixed threads or can dye them throughout of only one plain shade if
desired. The material is scoured and mordanted in the usual manner, in the
machine itself if desired, then it is submitted to the dyeing bath, rolled on the
machine and the ribbon is removed dyed on the parts, which were to be dyed, the
other parts remaining as they were before coming into the bath. One can thus
obtain with these ribbons or slivers mixed shades of lasting dye and without
felting.
In an ordinary vat there turns a large wheel R, on which is rolled the ribbon
which is scoured and mordanted as usually; care being taken to prevent certain
parts from coming in contact with the liquid by operating on such parts a
sufficient pressure for hindering the introduction and the circulation of the liquid
in the fibres. The wheel R is composed of two cheeks J forming rims at the end
of the spiders B with a nave M traversed by an axle A revolved by the gearing E
and the endless screw V operated by a pulley. These two cheeks are connected
together by means of cross pieces in order to form a drum. These cheeks have the
form shown in Fig. 4, that is to say thy have a rectangular flange in order to receive
pannels P having the aspect of a grate.
Fig. 1 shows the drum as being provided with 17 pannels er grates P attached
by means of bolts each having an intermediate collar and the 2 ends screw threaded
and provided with screw nuts X X These pannels could also be fixed by
other means. When the drum is provided with its pannels the sliver ribbon or
band or the like is rolled thereover in a convenient thick layer; then rods D are
inserted with their ends introduced into the guiding grooves so that the
said rods D are opposite the bars of the grate P and the bars of the grate P
Over these rods one continues to roll up the ribbon C, which 15 com-
posed of different slivers coming from several reels and connected into one
only by means of a draw plate or the like. The wheel R is put into movement in
order to obtain the rolling up of the ribbons. Over the rolled up ribbon are put
the pannels P1 analogous to the pannels P and which are pressed by the screw
nuts X or by another manner of fixing.
The parts of the ribbon thus compressed between the shoulder of a bar of the
grate and the face of a rod will not receive contact with the dyeing liquid in which
the whole system is then introduced. The parts however, which receive no pressure
will be in contact with the bath and will absorb the dye.

page_text: The immersion is made by turning the wheel in the liquid. When it has been
sufficiently long in the bath, the liquid is emptied and the usual rinsing done,
then the ribbon is reeled off after removal of the pannels P. It will be found
then that the ribbons are only dyed at the intervals corresponding with the distance
of the grate bars P and P¹.
Fig. 2 shows the drum in front view provided with two grates, the 15 other grates
having to occupy the spaces marked by divisions, as in Fig. 1. Fig. 3 shows a
cross section illustrating. the form of the bars of the grate and how the rods D
separate the ribbon into two distinct layers.
Of course the distance between the bars can vary and the empty spaces can be
either equal to or smaller or larger than the full parts. The drum R instead of being
cylindrical may be of a polygonal section, each surface being of any dimension.
During the immersion in the bath there is always a part of the drum which does
not dip into the liquid: one might secure the continuity of the operation by wetting
the part outside the bath by means of a pump, an injector or any dispersing device.
With this machine one can obtain uniform dyeing of the material for which
process it is sufficient not to insert the rods D and to place the pannels P¹ on the
textile material without pressure.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I
claim is:-
1. The improved method of dyeing at intervals textile materials in the state
of combing ribbons or slivers.
2. The before described machine for obtaining the dyeing in alternate places on
combing ribbons or slivers.
3. The construction of the same machine whereby it may be used for dyeing
textiles uniformly in only one plain color substantially as described.
