COMPLETE SPECIFICATION.
An Improved Machine for Printing on Textile Fabrics and
the like.
I JAIME BOLET of 7 Rue de Javellanos Barcelona in the Kingdom of Spain,
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 :-
This invention relates to a rotary machine adapted to operate by continuous
movement for printing on textile fabrics and the like by the aid of relief engraved
rollers and employing fatty inks.
•
Fig. 1 of the annexed drawing
of the machine.
an elevation, and Fig. 2 is a plan of an example
It is composed of three principal parts; the inking train, the printing rollers and
the feeding device for the fabric to be printed.
Ink is
The inking train contains the rollers, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10.
fed first to the roller 1 and the delivery is regulated by means of a longitudinal
batten 1 with adjusting screws. The roller 2 is mounted on a lever and by the
aid of a suitable cam, the roller 2 is lifted from time to time against the roller 1 to
take ink from the latter. The ink is then transmitted successively from one roller
to the other so as to lastly provide the printing roller a with a uniform ink
coating.
In order to forward the ink very evenly, one of the rollers, or more if necessary;
may possess apart from its rotary movement also a reciprocating longitudinal
movement imparted to it by a cam which latter is not represented in the drawing.
It is evident that the number and the distribution of the rollers comprising the
inking train, and also the material of which they are made, may differ without
departing from the general principle of this invention since the only purpose of
the inking train is to evenly feed ink to the cylinder a on which the design to be
printed has been engraved in relief. This inking train, can if desired, be provided
with an inking top plate but it is not necessary.
The printing mechanism consists of at least two rollers a and b. The roller a is
provided with any desired relief engraving (by any suitable means) that is to say
it has provided on its periphery the design to be printed on the fabric. This roller
may be of metal and may have its designs engraved on its surface; it may be of
wood and have the relief fastened thereon by means of screws;
may also for
instance consist of lithographic or other similar stone, the surface of which carries
the engraved designs, in the same manner as if any ordinary lithographic stone
were used.
For engraving stone rollers, transfers in fatty ink may be applied and the stone
etched with acids the respective operations being executed in the same manner as
with a lithographic stone. A stone roller when used, and the design thereon is no
longer required, may be turned down and polished again in order to receive another
design.
The bearings of the roller a may be fixed on the framework of the machine or
they may also be arranged adjustably at will by means of screws in order to give
the most convenient position to the roller.
The roller b has for its object to guide the fabric and to exert at the same time
a counter pressure against the printing roller a.

page_text: The bearings of the roller 6 can be adjusted in their supports by the screws h
and in order to displace the roller and to impart to it such position as is most
suitable for the pressure to be exerted thereby.
The supports may be fixed on to the frame work of the machine or they may
also be mounted on levers, pivoted at c as indicated in the annexed drawing which
levers are by the aid of screw connections f connected with the levers d g. In
the former case the roller is allowed to rise and fall within the supports by the
aid of the screws and hand in the second case said roller may be adjusted
and may also be moved by the movements which are transmitted to it by the
levers C, C¹.
By charging the extremities g of the levers with appropriate weights, the roller b
takes the position shown in dotted lines (6¹) arriving in contact with the roller a
and exerting upon the latter the requisite pressure for the correct impression of the
design.
ד
It is evident also that any other appropriate mechanism and means may be
employed in order to impart to the roller 6 the necessary pressure.
The cylinders a and b, instead of one of them 6 being placed above the other a,
may be arranged in any suitable relative positions towards each other since their
position is not of importance as regards the printing.
The machine represented on the drawing possesses only one inking train and only
one engraved roller a and therefore prints only one colour; in order that it may
print several colours it would be necessary to provide the machine with as many
separate inking trains and engraved rollers as there are colours to be printed.
Such different inking trains and rollers would have to be arranged laterally of or
above the roller b.
The fabric m to be printed on is wound on the roller i and moves in the direction
illustrated by the arrow over the guiding rollers m'; then passes between the
rollers 6 and a and away from the machine over roller m². The roller ; carries
the projecting cloth n which passes over the guiding roller n¹ and between the
fabric m and the cylinder 6 and over roller m². This protecting cloth n has for its
object to prevent the fabric m from coming into contact with the cylinder & which
might soil its undersurface.
From the foregoing it will appear that this machine prints on the fabric in a
continuous manner the fatty ink which it takes on the surface of the relief engraved
cylinder owing to the pressure exerted by any suitable medium and that it is a
matter of indifference what the position of the printing cylinder or cylinders may be
with respect to the pressing cylinder and what may be the direction of the passage
of the fabric and the protecting cloth to and from said printing cylinder.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A continuous printing machine adapted to print designs on fabrics in a fatty
ink or inks substantially as set forth.
2. In fabric printing machines as specified in Claim 1 one or more inking trains
consisting of a series of rollers of any suitable material (with or without the addition
of inking top plates) which uniformly spread out the fatty ink and transmit it to.
the engraved printing roller substantially as set forth.
3. In fabric printing machines of the specified kind, a roller for each colour
engraved with a relief design in combination with one or more other cylinders for
exerting counter pressure for the printing whatsoever be the relative position of the
cylinders and the rollers towards each other substantially as set forth.
4. In fabric printing machines as described, a litbographic stone or similar
stone roller, the surface of which is engraved by the aid of processes similar
to those applied to the ordinary lithographic stones substantially as set forth.
5. In fabric printing machines of the specified kind, a protecting cloth for the
purpose of avoiding the contact of the stuff or fabric to be printed with the pressing

page_text: cylinder in order that the fabric may not be liable to be soiled in any case, both
protecting cloth and fabric having any suitable passage through the machine
substantially as set forth.
