COMPLETE SPECIFICATION.
An Improved Machine for Printing Fabrics.
I, ARWED JAEHN, of Penig, in the Empire of Germany, Doctor of Philosophy
and Manufacturer, 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:
سلام
This invention relates to a machine for printing fabric, by which the printing
is produced in a mechanical manner analogous to printing by hand.
With this machine the fabric to be printed on, is laid on a stretched bearing
sheet or cloth of suitable material and is operated on by the passage of the form
roller, travelling over the same in connection with a counter printing roller pass-
ing under the carrying cloth and running with the form roller, and either the
printing apparatus is moved or the carrying cloth is drawn together with the
fabric through the printing apparatus
The annexed drawings illustrate the invention, and in which
Fig 1 is a partial side view of the machine

Fig. 4 18 a plan view of the counter roller bearing.

Fig 8 is a side view of a form of the machine having a stationary printing
apparatus and a movable bearing or supporting cloth
Fig. 9 18 a cross section of Fig 8
Between the guides A a carrying sheet or cloth B is stretched which gives to
the fabric to be printed on the necessary under layer or support
Over the cloth B there is arranged a framing D with an axle a seated thereon,
this framing D carries rollers 6 by means of which it runs on rails or the like of
the guides A. Along the latter there are arranged toothed rods or racks & with
which the toothed wheels a arranged on the axle a engage, so that by their move-
ment and the movement of the axle a, to which they are attached, the fram-
ing D is guided over the cloth B On the frame D 18 a carriage E movable over the
width of the machine and guided in suitable guides, which carriage carries the
form roller F together with the colour apparatus consisting of the colour band G,
two crushing cylinder pairs H and J and the colour box K
The movement of the form roller and of the rollers of the colour apparatus is
effected by means of corresponding toothed wheel gearings ƒ and g driven from
the axle a, on which the driving wheel of the gearing f 18 displaceable for instance
in a groove and under the action of a spring or in any other manner brought in
such a connection with the carriage E that it participates in its displacements or
adjustments, such displacements or adjustments being effected by means of sarew
spindle or other suitable means The gearings and 9 consequently remain
in the operative position.

page_text: The counter pressure rolle- L for the form roller, is arranged under the carry-
ang cloth B and pressed against the same by means of spring or other device and
13 seated on the carriage E' which 18 adjustable in the direction of the width of
the machine on the frame D¹ by means of the screw ' or the like, the frame D' is
provided with rollers b' and travels on toothed rods d' or racks of the guide A¹ and
is driven by the toothed wheels el mounted on the axle a¹ The shaft a¹ 18 driven
by means of the chain wheels k, in order to effect the proper movement of the
frames D and D¹, which chain wheels are moved by chains which guided by
1ollers are conducted round framing walls and are fixed on the front and back
side of the frame D arranged over the carrying cloth.
By means of a suitable heating device arranged preferably beneath the carry-
ung cloth an accelerated drying of the printing applied and also an uninterrupted
working is secured, which 18 especially assisted by the printing rollers being able
to travel backwards as well as forwards
The fabric or respectively several narrow strips of the fabric are laid in the
width of the machine over the whole length on the carrying cloth B
The printing apparatus including the counter roller L, is adjusted on one end
of the machine on the one or the other strip of fabric, by means of the screws h
and or the arrangement provided therefor
Then by turning the axle a the carriages D D¹ are simultaneously guided along
the guides A and A' that is to say, the form roller I as also the counter pressure
1oller L are rolled on the carrying cloth B covered with the fabric to be punted
on and by this means the pattern of the form roller is left on the fabric by the
effect of the colour band G.
When arrived at the end of the machine the form and counter roller carnages E
and E¹ may be adjusted on another fabric band and the printing with the same
or another pattern, respectively with another colour by changing the form roller
and the colour apparatus 18 effected backwards, until arriving at the starting
point when the process commences again.
With this machine there can be thus printed several bands of fabric arranged
in the width of the machine independently and differing in pattern and colour
from one another, the operation being such that the printing rollers travel on
the fixed fabric and the machine differs thus from other hitherto known machines,
in which the pattern is printed over the whole width of the machine and the fabric
to be printed on travels through between the rollers
In order to construct a machine having several printing rollers which can be
operated simultaneously the following arrangement is provided, as shown in
Figs 6-9
Over the guide framing there are arranged the two printing apparatus Z Z¹ in
such a manner, that they are arranged at both sides of the driving axle a
Each
of the two apparatus can be adjusted with regard to the width of the machine in
any manner desired and that in consequence thereof several bands are printed
uniformly or each of the two apparatus can work with separate colour and pattern
In certain cases the effect of both apparatus can also take place in such a
manner, that the same can successively apply a different pattern on the same fabric
width.
By means of the arrangement of the apparatus Z Z' on both sides of the driving
axle a the machine is more efficient without considerable changes being necessary
with regard to the driving arrangements.
In Figs. 8 and 9 there is represented an arrangement of the machine in which
the printing apparatus are arranged stationary and the carrying cloth B 18 con-
structed movable.
The latter is connected with driving chains t, which receive their movement
through a tooth wheel gearing m n o pqrs, so that the cloth B passing over the
wheels guides the fabric to be printed between the rollers F and L of the print-
ing apparatus.
The whole machine is driven by means of pulleys P mounted on the shaft a,

page_text: and the one or the several printing apparatus can be displaced and adjusted as
before described.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same 18 to be performed I declare that what I
claim 18.-
1. An improved web printing machine, in which the printing process is effected
by means of displaceable or stationary printing apparatus Z and a stationary or
continuously moving carrying cloth I, which in the latter case is guided through
between the form roller F and the counter roller L
2. An improved web printing machine as in Claim 1 in which a carrying cloth B
is stretched between the frame sides, on which the fabric lengths to be printed on
are laid longitudinally, over and under which carrying cloth, and fabric, there are
rolled the form roller F and its counter pressure roller L at any place, adjustable
at pleasure in the direction of the width of the machine, the above rollers being
respectively seated in carriages E E', which are displaceable on frames D D¹ in
the direction of the width of the machine, whilst the latter are moved by means
of rack and pinion movements de d'e in the direction of the length of the machine
and on the guides A A' and are kept also in equal forward and backward movement
since the said frame D' is in connection with the frame D by means of the chain
gearing Ik and also the colour apparatus 18 constructed for forward or backwaid
working by the arrangement of the double crushing roller pairs H, J
3. The improved web printing machine as in Claims 1 and 2, in which for the
purpose of simultaneously printing several bands or one band with several colours
there are arranged at both sides of the driving axle a two or according to the width
of the machine more printing apparatus Z Z which running beside or behind one
another can be operated simultaneously.
4. The improved web printing machine as in Claims 1 and 2 in which the
carrying cloth B 18 arranged continuously movable and the printing apparatus Z
18 stationary, for which purpose the cloth B is connected with the driving chain driven
by the wheels m n o p q r and s and is moved over the wheels s
