"IM-
My Invention has for its object to insure a more accurate register for the paper
in printing machines, whether it be in separate sheets or a continuous web, more
particularly in machines for printing simultaneously in several colours. For this
purpose, in place of the usual tapes employed for conveying the paper through the
machine, I employ endless metal bands or chains, having small spikes or pins at
distances apart, on to which the edges of the paper are pressed on being passed
between feeding rollers covered with felt, so that the paper is firmly held thereby
during its entire travel through the machine. By preference I employ in addition
to such metal bands or chains ordinary tapes of soft material, which at the feeding
end of the machine are caused by guide rollers to lay themselves upon the upper
edge of the paper after this has been placed upon the metal band, so that the spikes
of the latter are caused to pierce both the paper and the soft tape on passing through
the felt rollers, the paper being thus confined between the two tapes, and securely
held by the spikes during its travel through the machine. At the delivery end the
soft tapes are lifted off the paper by guide rollers, and the paper is then raised off
the spikes of the metal conveying bands by means of lifting plates acting from
below.
The guide rollers for the metal tapes have flanges to confine them in position,

page_text: and they are adjustable upon their axes to suit paper of different widths; one or
more of the printing rollers also have adjustable flanged rings on their ends for
guiding the tapes; these are kept stretched by means of rollers adjustable by means
of screws.
When the machine prints upon separate sheets, instead of on continuous web, spring
grippers are provided at the feeding end, acted on by a cam, so as to seize the sheet
presented to it and press it upon the spikes of the‘metal tapes just before the soft
upper tapes are brought down upon them.
As, after passing between the printing cylinders, the tapes have a tendency to
separate, this is prevented by placing on the delivery side of each cylinder sunall
guide rollers so arranged as to keep the two tapes close together on passing from
the cylinder.

PROVEMENTS IN PRINTING MACHINES."
My Invention has for its object to insure a more accurate register for the paper
in printing machines, whether it be in separate sheets or in continuous web, more
particularly in machines for printing simultaneously in several colours. For this
purpose, in place of the usual tapes employed for conveying the paper through the
machine, I employ endless metal bands or chains, having small spikes or pins at
distances apart, on to which the edges of the paper are pressed on being passed
between feeding rollers covered with felt, so that the paper is firmly held thereby
during its entire travel through the machine. By preference I employ, in addition
to such metal bands or chains ordinary tapes of soft material, which at the feeding
end of the machine are caused by guide rollers to lay themselves upon the upper
edge of the paper after this has been placed upon the metal band, so that the spikes
of the latter are caused to pierce both the paper and the soft tape on passing
through the felt rollers, the paper being thus confined between the two tapes and
securely held by the spikes during its travel through the machine. At the delivery
end the soft tapes are lifted off the paper by guide rollers, and the paper is then
raised off the spikes of the metal conveying bands by means of lifting plates acting
from below.
The guide rollers for the metal tapes have flanges to confine them in position,
and they are adjustable upon their axes to suit paper of different widths; one or
more of the printing rollers also have adjustable flange rings on their ends for

page_text: guiding the tapes; these are kept stretched by means of rollers adjustable by means
of screws.
When the machine prints upon separate sheets instead of on continuous web, spring
grippers are provided at the feeding end, acted on by a cam, so as to seize the sheet
presented to it and press it upon the spikes of the metal tapes jast before the soft
upper tapes are brought down upon them.
As, after passing between the printing cylinders, the tapes have a tendency to
separate, this is prevented by placing on the delivery side of each cylinder small
guide rollers so arranged as to keep the two tapes close together on passing' from
Fig. 1 is a longitudinal section, and Fig. 2 a plan of a machine for printing in
several colours, to which my Invention is applied, Fig. 5 being a transverse
section thereof.
Between the several printing cylinders A, B, I pass endless metal tapes a, which
pass round the six rollers r, and are kept stretched by rollers r adjustable by
screws y'. These tapes, as shewn in the transverse section to an enlarged scale,
Fig. 3, are at certain intervals provided with the spikes or pins p, which penetrate
and hold the paper. The tapes, besides being guided between flanges of the rollers r,
are also guided by flanges of the middle upper cylinder A', as shewn in the part
section, Fig. 4, these flanges being formed on collars 6 that can be fixed on the
cylinder by screws c in various positions to suit different widths of paper. The
rollers can also be shifted along their spindles, and secured at the required distance
apart by setting screws f. Each of the tapes a, a portion of which is shewn to an
enlarged scale at Fig. 6, besides having the spikes p projecting from its surface, has
intermediate holes through it, into which enter spikes on the driving roller, so as
to ensure the movement of the tape without slip.
In order so ensure the penetration of the paper by the spikes p I employ upper
tapes al of soft fabric, as shewn in Fig. 3, with the paper x held between them, and
the metal tapes a below. These upper tapes a¹ are carried over rollers ² adjustable
in height to give the required tension to the tape.
At the feeding end of the machine is provided a set of grippers g, the lever of
which, h, is worked by a cam k on the axis of the roller o, a spring pressing the
lever against the cam.
When, instead of separate sheets a continuous web of paper is printed, the roll R
is mounted on separate framing, the grippers being in that case dispensed with.
At the delivery end of the machine, when it is used for separate sheets, there aro
springs m on the axis q of a lever a worked by the cam t. These springs raise the
paper x off the spikes of the tapes, so that it is discharged by the striker y.
To prevent the tapes from tending to separate by following the curvature of
the cylinders on leaving the point of impression, I provide pairs of small smooth
rollers g to each pair of cylinders, which press together the tapes with the paper
between them.
The machine, arranged as described, is applicable for printing paper hangings or
fabrics with a number of different colours.
A like arrangement of tapes is applicable also to simple printing, as may be
readily understood.
Having thus described the nature of my Invention, and in what manner the
same is to be performed, I claim,―
First. The use in printing machines of metal travelling tapes, with spikes pene-
trating the paper, for the purpose of ensuring the true register, substantially as
herein described.

page_text: Second. The combination of a soft upper tape with a lower spiked tape, between
which the paper is pressed, substantially as and for the purpose herein set forth.
Third. The mechanism herein described for the feed and delivery of the paper.
In witness whereof, I, the said Emile Vauthier, have hereunto set my hand
and seal, this Twenty-eighth day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
