Improvements in Machines for Printing Textile Goods, Paper
Hangings, and such like by Endless Templates Having Variable
Thickness of Material.
I, FRITZ WIEBEL of Elberfeld, Rhenish Prussia, Germany, Merchant,
Oberstrasse 26, 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 relates to machines for printing textile fabrics and paper hangings
and has for its objects to allow by the mechanical arrangements of my printing
machine made for the purpose, the use of endless templates for patterns of any
size of ornaments, these templates having various thickness of stuff in various
places of the same, in order to vary the intensity of the colour in these places.
A further object in view is to be able to conveniently put in and out the colouring
apparatus of the machine, and finally to provide for an automatic parallel guiding
of the moving template. This is of importance on account of the varying thickness
of the template in various places.
By the realisation of these objects the restricted field for the extent of the
repeating surface dimensions of the design of the patterns, to which the engraved
printing rolls of the machines used hitherto in printing paper hangings or textile
fabrics, are limited, is enlarged in my machine.. At the same time I avoid the
impossibility inherent to the hitherto known machines to produce different
intensities of shades of one and the same colour during one and the same passage
of the goods through the machines, and from one and the same colour-roll; or to
produce gradations of the colour in following the contour of the design on the
printing rolls.
The annexed drawing fully represents my invention and shows in:
Fig. 1 a side elevation
Fig. 2 a front view seen from the left of Fig. 1;
Fig. 3 is a plan, and
Fig. 4 shows in an enlarged scale the arrangement for supporting the rear guide-
roller for self-adjustment.
Fig. 4 is a side view of Fig. 4.
Fig. 4 a top-view of a sliding shoe of the cross-head;
Fig. 5 shows a part of a template in plan and in cross-sections I-I
and II-II.
This new printing machine is to work with endless templates of peculiar
constitution and make, and in order to perform this work in the most advantageous
manner, its mechanical arrangement is the following:
In a suitably consolidated framework 1, the roll 2, containing the material to be
printed, is journalled in outside bearings, and its shaft is provided with a lever
brake 3, weighted suitably in order to secure a regular unwinding of the stuff 4,
which, in order to be printed, is led over guide-rolls and tightening-rolls 5, 6, to
the main working drum 7 on which it is lying close over the greatest part of its
circumference, leaving it at the lower part 8, in order to be led over another guide-
roll 9 and further on, either to a drying device or, as shown in the drawing, on to
a winding-up roll 10, situated in the frame in suitable bearings.
The drawing shows further to the left of the main-drum a guide-roll 11 above
and a guide roll 12 below the horizontal centre-line; the former, 11, is touching

page_text: in its whole length the main drum 7 and is revolving in adjustable bearings allowing
an exact contact between the roll 11 and the drum; the other guide-roll 12 may
be weighted so as to keep the template under tension; an adjustable roll 13 is fixed
near the left hand end of frame 1.
The endless template of peculiar make 14 is laid over the said three rolls 11, 12
and 13, so that rolls 11 and 12 keep it tightly close to the drum, and the stuff 4 to
be printed on the drum and so, that the friction and adhesion between the stuff on
the drum and template cause the latter to run over its rolls and along with the
stuff 4 when the drum is revolving; gear wheels and pinions may be used to
support and to secure this motion of the template.
The inner free space circumscribed by the template led over the three rolls 11,
12, 13, is partly occupied by the colouring apparatus 15, of known and approved
construction. The colouring rolls 15" are mounted in a suitable support, movable
on a sliding table 16, so that the colouring device may be pulled out sideways, on
to a table 16ª.
The table 16 is not fully bridging the space between the two frames 1, 1, it
extends only from each standard inwards for a certain length, leaving a free gap
between these two half tables in order to enable the endless template to be taken
out of the machine when the colouring device is pulled out so far as to give it
passage, as shown in dotted lines in Fig. 3.
As it is impossible to obtain graduations in colour intensity in one and the same
passage of the goods by template-printing with ordinary templates, I have devised
a new template of variable thickness of material at the desired places, as in Fig. 5,
in combination with a new self-adjusting arrangement for the guide-roll 13, which
enables a true running development of the template notwithstanding its various
thickness of material or paper at the different places of its surface. This guide-
roll 13 is running in bearings in a forked bracket 22, Fig. 4, which has in the
middle a short arm with a ball and socket joint, lodged in a cross-head 19, sliding
with its shoes 20, 20, in a guide-groove in each of the frames 1, 1, and provided
with a screw 24 and hand-wheel nut 21, turning in a cross-piece 23 of the frames 1, 1,
and allowing to regulate the tension of the template 14. By this device I am
enabled to put at different places of the template more or less thick frisket-sheets
or strips pasted on it or other thickening pieces, causing a more or less close
contact of the surface of the elastic colouring roll 17, through the openings in the
template 14, with the stuff 4 to be printed, and producing so a more or less copious
and intense colouring of the goods and thereby gradations of the colour-intensity
in one and the same passage by one and the same colouring roll, in the different
places of the template and in the regularly continuing printing-process making
thoroughly perfect goods.
This is only possible by the use of the automatically adjusting device of guide-
roll 13 described, which for any position taken by the guide-rolls 11, 12, takes an
exactly parallel position to them and so insures true, uniform and parallel travel of
the template 14 over the three leading rolls 11, 12, 13, in spite of the variation of
the central distances between the axis of rotation of the cylinders 11, 12 and
of colouring roll 17 in consequence of the passage of thicker or thinner places of the
template, though these variations are very small, they would, if not compensated
make impossible a parallel passage of the template. The ball and socket arrange-
ment of the movable forked roll-holder 22 equalises momentaneously the differences
in tension and restitutes the parallelism of the axis in question.
For printing goods with several colours, similar colouring arrangements may be
added by arranging them on the circumference of the main drum.
I am well aware that printing by means of templates and by roller presses has
been done before and I do not claim broadly such process of printing; but the use
of templates having varying thickness at different places is quite new and makes a
special part of my invention, and the machine invented by me for that purpose, so
that the templates of varying thickness can be kept in true parallel motion, is also
quite new.

page_text: 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. In a machine for printing textile goods, paper hangings and like goods in long
strips, the combination of frames 1, a stuff-carrying roll 2, guide rolls 5, 6, and 9,
a taking up roll 10, mounted in the lower part of said frames and a drum 7
mounted on the top rail of frames 1, with an endless template 14, said template
varying in thickness at certain places, guide rolls 11, 12 and 13 guiding said
template so that it will touch and surround partly the stuff 4 on the drum 7 and
with a colouring device 15 placed inside the hollow space or loop formed by the
endless template, the whole as described and illustrated and for the purpose
specified.
2. In a machine for printing textile goods, paper hangings and like goods in
long strips, the combination of frames 1, a stuff carrying roll 2, guide-rolls 5, 6
and 9, a taking up roll 10 mounted in the lower part of said frames and a drum 7
mounted on the top rail of frames 1, guide rolls 11, 12, 13, taking up the endless
template and guiding the same so that it will touch and surround partly the stuff 4
on the drum 7, a colouring device 15 placed inside the hollow space or loop formed
by the endless template, with a cross head 19 sliding in side grooves of the frames 1
and carrying by ball and socket joint a bracket 22 supporting the guide roll 13
and thus enabling it to adjust itself automatically to the unequal tension of the
template 14.
3. In a machine for printing textile goods, paper hangings and like goods in
long strips the combination of frames 1, rolls 2, 5, 6, and 10, drum 7 and rolls 11,
12 13, template 14 and colouring device 15, sliding cross-head 19 carrying by ball
and socket joint in a bracket 22 the guide roll 13, with a screw and hand wheel 24
and 21 respectively for adjusting the roll 13 according to various lengths of
templates, the whole as illustrated and described and for the purpose specified.
Dated this 3rd day of August 1896.
