Improvements in or relating to Processes and Apparatus for
Printing Woven Fabrics or Yarns in Skeins.
We, GERSON MARKUS, and MAX BAENDER, Merchants, and FERDINAND
SICKER, Engineer, all of 3 Marszalkowska Strasse, Warschau, Poland, do hereby
declare the nature of this invention to be as follows:-
This invention relates to processes and apparatus for printing yarns in skeins, or
woven fabrics in any desired lengths for various purposes.
Hitherto it has been customary to print yarns for textile purposes upon machines
with fluted rollers, or the yarn has been wound on a large drum and printing effected
thereon by a roller dipped in colour.
In both these methods of printing it has been impossible to apply successive
colours, because the colours ran, and in particular by roller-printing, no sharp
boundary-lines between the different strips of colour were possible, whereby the
sharpness and clearness of the pattern were greatly diminished.
An
These drawbacks are now entirely overcome by our improved process.
important novel feature of this new process is that the separate colour-strips are
imprinted on the yarn or skein, or upon the textile fabric itself by rods or bars.
These bars are provided on their undersides with means for taking up the colour,
.e: with a printing surface, and arranged close to one another, form a printing block,
in continuous motion, whereby the colour is printed on the skeins or on the fabric,
as the case may be, which is suitably pressed against such block by rollers or the
like.
With this process, the individual rods or separate scries thereof may receive single
colours, which are printed off upon the yarn (or tissue) side by side, the boundary
lines between two different shades or colours being clearly and sharply defined so
that the weaving of the yarn thus printed leaves nothing to be desired in point of
clearness..
The
yarns to be printed before being placed in the printing machine are prepared
and arranged in skeins according to the pattern and then laid on three or any other
convenient number of rollers over which an endless web runs as well as round a
supplementary roller. If the skein to be printed is short, it is carried over straining
rollers besides the rollers above-named; while at the same time by means of a
wind-wheel or fan in a drum the drying of the printed skeins, led round the said
drum is effected. The rollers are preferably arranged in their bearings so as to be
adjustable in reference to the printing apparatus in order that the distance from the
printing surface may be varied as necessary.
The printing apparatus is arranged as follows;—
Two parallel shafts are mounted horizontally on the machine frame and cach
carries two discs round which two endless bands are led. Upon these two endless
bands is a series of pins serving to retain printing bars which are laid side by side
on the endless bands and moved forward in parallel manner as the endless bands
advance.
The printing bars are provided with the requisite colour on their under surfaces
in the respective colour holders. Their under surface is provided for this purpose

page_text: with a strip of felt or other like porous material so as to enable it to take up
sufficient colour. Both sides of the several bars are covered over with thin metal
sheets, so that the lower edges of the printing surface of the bar are sharply defined.
The rods duly charged with colour are now arranged on the endless bands as above
described side by side, with the coloured side downwards (or outwards). As the
endless bands pass along the rods are brought into contact with the yarns (or
tissues) arranged on and passing round the rollers and thus complete their work of
printing. By the arrangement of these rollers the intimate contact between the
printing block and the material to be printed is so sustained that an adequate and
regular transfer of colour from the block and consequently an even and sharp
impression is obtained and assured.
It results therefrom as will be seen from the foregoing that the several bars or
series of bars charged with different colours, impress these side by side, without the
colours running into one another. The longitudinal edges of the metal strips
provided on the printing surfaces of the bars guarantee the sharp and clear
definition of the boundary lines between the different neighbouring and adjoining
colours.
After the bars have thus effected their printing work, they pass away, above,
and drop on a guide-frame which conducts them away on one side, so as to be again
charged with colour and laid anew upon the endless bands, for a repetition of the
same process.
If it be required to print a piece of textile fabric the same is passed through the
printing machine, commencing at one of the three first-named rollers where it is
introduced into the machine, and quitting it after having gone nearly round the
before-mentioned drum in a condition sufficiently dry for the colour to have become
fixed and not to smudge or come off, so as to be in any way tarnished or discoloured
or have the outlines blurred. It is evident therefrom that the length of the piece
to be printed may be as desired.

Improvements in or relating to Processes and Apparatus for
Printing Woven Fabrics or Yarns in Skeins..
We, GERSON MARKUS, and MAX BAENDER, Merchants, and FERDINAND
SICKER, Engineer, all of 3 Marszalkowska-strasse Warschau, Poland, do hereby
declare the nature of this invention and in what mauner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to processes and apparatus for printing yarns in skeins, or
woven fabrics in any desired lengths for various purposes.
Hitherto it has been customary to print yarns for textile purposes upon machines
with fluted rollers, or the yarn has been wound on a large drum and printing effected
thereon by a roller dipped in colour.
In both these methods of printing, it has been impossible to apply successive
colours, because the colours ran, and in particular, by roller-printing, no sharp
boundary-lines between the different strips of colour were possible, so that the
sharpness and clearness of the pattern were greatly diminished.
These drawbacks are now entirely overcome by our improved process. An
important novel feature of this new process is that the separate colour-strips are
imprinted on the yarn or skein, or upon the textile fabric itself, by rods or bars.
These bars arranged close to one another, form a priuting block and are set in

page_text: like.
An apparatus for carrying out this improved process is shown in the accompanying
drawings wherein,―
Fig. 1 is a side elevation ;
Fig. 2 a plan;
Fig. 3 a vertical transverse section on the line A B of Fig. 1 ; and
Fig. 4 shows the arrangement of the printing-bars on endless bands i¹.
Figs. 5 and 6 show a separate printing bar in side and end view respectively.
The yarns to be printed, e.g. before being placed in the printing machine are
prepared and arranged in warp-shape according to the pattern. The warp thus
obtained is then laid on the rollers 6 3 over which an endless web runs as well
as round a supplementary roller e¹. If the warp to be printed is short, it is
carried over straining rollers ff, besides the three rollers above-named; if however
it is according to the pattern longer it is carried over the drum k as well as over
several tension-rollers f, while at the same time, by means of a wind-wheel or
fan m in the drum k the drying of the printed material led round the said drum k,
is effected. The rollers 6' 63 63 are preferably arranged in their bearings so as to be
adjustable in reference to the printing apparatus, in order that the distance from the
printing surface may be varied as necessary.
The printing apparatus is arranged as follows;-
Two parallel shafts c and c¹ (Fig. 2) are mounted horizontally on the machine-
frame, and each carries two discs a round which two endless bands i are led. Upon
these two endless bands is a series of pins, serving to retain the printing-bar h which
are laid side by side on the endless bands and moved forward in parallel manner as
the endless bands advance, as shown in Fig. 1.
The printing-bars are provided with the requisite colour on their under-surfaces
in the respective colour-holders. Their under-surface is provided for this purpose
with a strip of felt or other like porous material so as to enable it to take up
sufficient colour. Both sides of the several bars are covered over with thin metal
sheets, so that the lower edges of the printing surface of the bar are sharply defined.
The rods, duly charged with colour, are now arranged by hand on the endless
bands i, as above described, side by side, with the coloured side downwards (or
outwards). As the endless bands i pass along the rods are brought into contact
with the warp (or tissues) arranged on and passing round the rollers 6¹³ ³, and
thus complete their work of printing. By the arrangement of these three rollers
the intimate contact between the printing-block and the material to be printed is so
sustained that an adequate and regular transfer of colour from the block and
consequently an even and sharp impression is obtained and assured.
It results as will be seen from the foregoing that the several bars or series of
bars, charged with different colours, impress these side by side, without the colours
running into one another. The longitudinal edges of the metal strips provided on
the printing-surfaces of the bars guarantee the sharp and clear definition of the
boundary-lines between the different neighbouring and adjoining colours.
After the bars have thus effected their printing work, they pass away above and
drop on a guide-frame which conducts them away, on one side, so as to be again
charged with colour and laid anew upon the endless bands, for a repetition of the
same process.
If it be required to print a piece of textile fabric the same is passed through the
printing-machine, commencing at the roller where it is introduced into the
machine, and quitting it after having gone nearly round the before-mentioned
drum k in a condition sufficiently dry for the colour to have become fixed and not to
sinudge or come off, so as to be in any way tarnished or discoloured, or have the
outlines blurred.
It is evident therefrom that the length of the piece to be printed may be as
desired.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. A process for the printing of yarns in the form of warps, or of textile fabrics
in the piece, wherein bars, provided with an outer printing surface, are continuously
arranged side by side with their longitudinal edges in juxtaposition, and against the
travelling printing-block thus constituted, by means of the several printing-bars,
the material to be printed is duly pressed, and thereafter the said printing form,
by the separation of its separate bars, is again distributed (the bars being guided
out of the machine by a guide-frame Z, which is readily removable) and after the
said several bars have been dipped each in the required colour, contained in a
separate receptacle (according to the pattern) as required, is again reconstituted in.
the manner described.
2. A machine for carrying out the process described in Claim 1, characterised by
the arrangement of printing-bars (h) taken up by endless bands ii carried by discs a a,
in combination with guide-rollers 61 62 6³, for conducting the material to be printed,
in such manner that, by the forward motion of the endless bands i, the printing
forme composed of coloured printing-bars continually imprints the colours upon the
material to be printed upon, correspondingly moved therewith, while after the
transfer of the impression, the printing rods composing the forme are carried away
to one side of the fixed frame of the machine by a movable frame Z, for the purpose
of being once more dipped in the proper colour-receptacles and again arranged upon
the endless travelling bands in the same way as before, and so on.
3. The combination and arrangement of parts constituting a complete colour-
printing machine substantially as and for the purpose herein before described and
illustrated in the accompanying drawings.
