An Improved Machine for Dyeing Slivers or similar substances
used in the Manufacture of Ribbons Direct from the Combs,
and for like purposes.
I, JULES AUGUSTE JOSEPH FLORIN-LECLERCQ, of 85 Rue du Général Changy,
Roubaix, France, Commercial Traveller, do hereby declare the nature of this
invention to be as follows :-
My invention has for its object the dyeing of the material used in the manufacture
of ribbons, when coming direct from the comb-bobbins, without passing through the
intermediary of the gill-boxes, as in other machines.
The slivers or other materials obtained by unrolling the bobbins, pass through.
two rectangular cells, and through an agitator composed of two laths or rods fixed
to two sliding regulators, mounted on an axle fastened by cranks to two discs,
rotating in a groove, which regulate the commencing course of the material,
producing a rapid succession of vertical concussions, the object of which is, to
widen and flatten the material in such a manner as to obtain a band of uniform
thickness.
The material then passes between compressors and then between the first pair of
printing rollers, one of which is fluted, and it receives an impression upon its
lower face. It then ascends to receive an impression upon its upper face from the
second pair of printing rollers. This further movement effects the removal of the
smoothness on the lower face, by ruffling the surface formed in the first process of
colouring; and this brings out successfully the required effect on the face of the
material.
'
The colour rollers receive their colour from two feeding rollers working in
contact. It is understood that the flutes of the rollers cause prominences in the
material brought into contact with them, and these will receive the colour, while the
portions in the hollow of the flutes will remain uncoloured.
On leaving the printing rollers, the tinted or dyed material passes over three
other rollers which separate it, and pass it on to receptacles placed to receive it.
The dye is then fixed, the material washed and dried and re-wound on bobbins.
The colour rollers have surfaces of some soft material such as india-rubber or
cloth.

COMPLETE SPECIFICATION.
An Improved Machine for Dyeing Slivers or similar substances
used in the Manufacture of Ribbons Direct from the Combs,
and for like purposes.
I, JULES AUGUSTE JOSEPH FLORIN-LECLERCQ, of 85, Rue du Général Changy,
Roubaix, France, Commercial Traveller 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 :-
My invention has for object the dyeing of slivers or ribbons, in an early stage of
manufacture, when coming direct from the comb-bobbins, without passing through.

page_text: the intermediary of the gill-box, as in other machines. This is effected by the aid
of a special machine invented by me, which I will now proceed to describe with
reference to the accompanying drawings, in which
Fig. 1 shews a side elevation of my machine, and Fig. 2 a plan of one of the
parts called tringles.
The machine shewn functions in the following manner as will be readily understood
from the said drawings.
The slivers obtained by unrolling the bobbins pass through the rectangular
openings of a fixed tringle I Figs. 1 and 2, and then between a first pair of
regulable tension rollers M, M, Fig. 1.
They then undergo the action of an agitator composed of two tringles H, H,
fixed to two sliding regulators L, mounted on a bar N, which is joined by cranks P,
to two rotating disks S, in the slide T, which arrangement regulates the course of the
material U, and imparts to it a rapid succession of vertical concussions or blows
the object of which is to widen and flatten the material in such a manner as to
obtain a band of uniform thickness.
The working of this agitator may be effected by any suitable means and the
construction of the agitator itself can be varied provided the foregoing result is
produced.
After being submitted to this agitation, the material crosses a second perforated
bar J, similar to the first I, and then passes between a pair of compressing
rollers M³, M³, the pressure of which like the rollers M, M, can be regulated in
any well known way, as for instance by a hook and weight as shewn by Y, and Z.
These rollers flatten the surface similarly to the tension rollers M, M, and
pressure box M¹¹.
On leaving these rollers the combed material descends towards the first printing
rollers A, and B, and passes between them, thereby receiving an impression on its
lower surface. After this passage it ascends towards a second series of printing
rollers E, and D, to receive an impression on its upper face. This serpentine
movement of the ribbons produces the best results but the material may when
preferred pass horizontally from roller to roller. The rollers B, and D, are fluted
and the dimensions of the flutes can be varied as desired. A, and E, are the
printing rollers and have their surfaces perfectly smooth.
They receive this supply of colour from two other feeding rollers C, and F,.
rotating in contact with them, under a suitable pressure regulable by the
screws C¹, F¹, or in any other suitable way, so that they furnish a regular supply
of colouring matter to the rollers A, and E. It will be understood that the pro-
jections of the fluted rollers B, and D, cause those parts of the material which fall
upon the prominent parts of these rollers to receive the colour under pressure and
that the uncolored spaces of the material correspond to the flutes or intervals
between the projections.
These two successive series of printing rollers are necessary in order to make the
printed impressions correspond in shade on the two faces of the same material. As
many different kinds of impressions as required can be printed by multiplying
these double series of rollers one after another, either with a serpertine or horizontal
movement of the surfaces of the material operated on. When several bands of
material are operated on at one time as is contemplated the colored or dyed
material, as it leaves the last pair of printing rollers, separates and passes over the
rollers X, X, which permit the varicus bands to be deposited in the separate
receptacles K, K, thus avoiding their becoming mixed. The material is next
fixed, washed, dried and rewound on to bobbins. If desired the rollers X, X', at
the exit can be replaced by spreaders or other means of effecting the required
result. The operation of all these parts is effected by the main shaft of the
machine which distributes the necessary power by means of gear wheels of suitable
dimensions.
The fluted rollers are geared direct and the printing rollers work by simple
contact or can be geared and driven by their axles.

page_text: inis arrangement of the direct gearing rollers effects the regular delivery of the
material.
The fluted roller being of metal or other hard substance is invariably of the same
diameter whilst the diameter of the printing roller can vary, from the fact of its
being coated with elastic substance such as indiarubber, gutta-percha, cloth and the
like.
My dyeing process consists of two successive operations, first, the passage
through the agitator and compressors as before described, which has the effect of
flattening all the material into an uniform thickness and next, the coloring of the
material on one surface and then the same operation on the other surface. This
process may be called alternative and reverse printing.
It results from the compression of a hard, fluted roller upon a soft or com-
pressible substance. Greater precision and distinctness of effect are produced by
this method in the application of the colouring matter than can be obtained in the
compression of two fluted rollers with compressible or soft surfaces which often
cause a defective and unequal distribution of the colour. By my process I compress
a substantial thickness of ribbons united in one surface, without their undergoing
the action of the gill box. I dispense with the cost of this machine and the incon-
veniences consequent upon its action, such as the frequent renewal of the bars, the
waste and damage to the material and the isolation of the surfaces operated on. I
obtain in these respects a great advantage and economy in the dyeing of ribbons or
slivers from the combs. The feeding rollers C, and F, turn in the usual troughs
containing dye and above the machine is placed a receptacle for feeding these
troughs by means of small pipes furnished with taps to renew the dye which is
absorbed in the troughs. These troughs are furnished with another receptacle
which takes off the overflow into a reservoir beneath the machine. A pump is
continuously employed for raising the coloring matter from the lower reservoir to
the higher from which any overflow is again carried below to the lower reservoir.
This constant flow has the advantage amongst others, that whilst renewing the dye
it avoids the froth which arises if the dye is allowed to remain too long in the
troughs of the rollers as the rollers are apt to cause froth by their rotation. This
froth not only prevents a good surface of color on the feeding roller but also causes
the dilution of the dye upon the printing roller.
Although the object of my machine is chiefly to dispense with the gill box, I
reserve the right to add gills at the commencement of the action of the machine
described above, as also before each pair of printing rollers, when it is desired to
employ simultaneously two or more colors.
I also equally reserve the right to employ any compound or exceptional products
of color on the ribbons from the combs as well as coloring matters properly so
called.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The direct and alternative process of dyeing ribbons or slivers from the combs
by means of rotating rollers, that is to say by the compression of a hard or metallic
fluted material on a printing roller of which the periphery is compressible and
formed of indiarubber, gutta-percha, cloth and the like, as herein described and
set forth.
2. The combination of the various parts of the machine before mentioned giving
the results herein defined, as also its construction in any preferred form, size, pro-
portion or materials, such machine effecting the dyeing of ribbons or slivers from
the combs, or of their surfaces in one or more colours, as herein described and set
forth.
3. The agitator combined with regulators furnished with rectangular openings
for the purpose of flattening the ribbons into a regular surface, or any similar
arrangement for effecting this object as herein described and set forth.

page_text: 4. The arrangement in suitable positions of the compressible rollers and the
fluted rollers, to obtain a serpentine movement of the ribbons or slivers, from which
a greater regularity in the dyeing, results, as herein described and set forth.
5. The application of a pump to obtain the continuous circulation of the colouring
liquid in the reservoirs and colouring receptacles, which assures the regular feeding
of the printing rollers and exemption from the presence of froth with the coloring
matter as herein described and set forth.
Doted this 28th day of March 1893.
