Improvements in and relating to Calico or other Web Fabric
Cylinder Printing Machines.
We, R. DALGLISH FALCONER & CO. LIMITED, Lennoxmill, Lennoxtown,
Stirlingshire, Calico Printers, and JAMES BLAIR, Assistant Manager to said
Company do hereby declare the nature of our invention to be as follows:-
This invention has reference to improvements in the construction or the arrange-
ment and combination of the parts of cylinder printing machines for printing calico
or other web fabrics and has for its object the enabling of such machines to print
shaded, clouded, or imitation woven effects to be printed from ordinary engraved
printing cylinders either alone or in combination with ordinary pattern effects.
The fabric to be printed with its usual backing is conveyed to the printing
machine in the ordinary manner and in order that the fabric may travel at the same
speed as the "bowl" or drum it is entered through one or more "nips" of the
machine, that is it is passed between said "bowl" and one or more of the ordinary
rollers, which may be plain or engraved and may or may not be supplied with
colour.
The fabric is then carried outwards from the "bowl" over a loose roller which
is mounted in bearings on machine frame or on brackets thereon, or it may be a
fixed spar instead of a roller, whence it is conveyed into printing contact with one
or more engraved printing cylinders which may or may not be in contact with the
"bowl" of machine, and which may rotate in either direction.
When more than one cylinder is used to produce the shaded effect a loose roller
or spar may be mounted in front of each one.
The printing cylinder or cylinders used to produce the desired effects and which
are preferably carried in adjustable box bearings on machine frame are so connected
by wheel or chain gearing with the bowl or other moving part of machine that
they rotate at either a greater or less circumferential speed than same when both
run in corresponding directions and at any desired speed when the cylinders turn
in the reverse direction and thus causes the pattern on roller to drag over the cloth
and so deposit the colour thereon in a shaded or cloudy manner instead of forming
a sharp impression as in the ordinary method of printing.
After being so printed the fabric is passed through one or more "nips" of the
machine the cylinders used being plain, or engraved without being supplied with
colour if no further effect is to be produced, but further printing may be effected
in the ordinary manner.

Cylinder Printing Machines.
We, R. DALGLISH FALCONER & Co., LIMITED, of Lennoxmill, Lennoxtown,
Stirlingshire, Calico Printers, and JAMES BLAIR, Assistant Manager to said
Company, do hereby declare the nature of our invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement in writing:
This invention has reference to improvements in the construction or arrangement
and combination of the parts of cylinder printing machines for printing calico or
other web fabrics and has for its object the enabling of such machines to print
shaded, clouded, or imitation woven effects from ordinary engraved printing
cylinders, either alone or in combination with ordinary pattern effects.
And in order that our said invention and the manner of carrying same into
practice may be properly understood we have hereunto appended an explanatory
sheet of drawings in which
Figure 1 is a diagrammatic view of a cylinder printing machine as fitted in
accordance with our improvements, and
Figure 2 is a similar view showing the arrangement of the driving gear.
The fabric to be printed with its usual backing is conveyed to the printing
machine in the ordinary manner and in order that the fabric a may travel at the
same speed as the bowl or drum A it is entered through one or more "nips" of the
machine, that is, it is passed between said "bowl" A and one or more of the ordinary
rollers A which may be plain or engraved and may or may not be supplied with
colour.
The fabric a is then carried outwards from the "bowl" A over a loose roller B
which is mounted in bearings on machine frame or on brackets thereon, or it may
be a fixed spar instead of a roller, whence it is conveyed into printing contact with
one or more engraved printing cylinders C, fitted with the usual "doctors" C¹
which may or may not be in contact with the "bowl" A of machine, and which
may rotate in either direction.
Preferably and as illustrated, the cylinders C are fitted out of contact with the
" bowl
A and are driven at a lower rate of speed than the others A' A' in contact
with the bowl A. When it is desired to rotate the cylinders C in the opposite
direction appropriate gearing is employed.
When more than one cylinder C is used to produce the shaded effect a loose
roller B or spar may be mounted in front of each one, as also behind the last one.
The printing cylinder or cylinders C used to produce the desired effects and
which are preferably carried in adjustable box bearings on machine frame are so
connected by wheel or chain gearing with the bowl or other moving part of machine
that they rotate at either a greater or less circumferential speed than same when
both run in corresponding directions and at any desired speed when the cylinders
turn in the reverse direction and thus cause the pattern on roller to drag over the
cloth and so deposit the colour thereon in a shaded or clouded manner instead of
forming a sharp impression as-in the ordinary method of printing.
After being so printed the web fabric a is passed between one or more nip
rollers A and the surface of "bow!" A the rollers A being plain or engraved and
without being supplied with colour if no further effect is to be produced but
further printing may be effected in the ordinary manner when a combination of
effects is desired.
In Figure 2 the arrangement of gearing is shown consisting of a spur wheel D

page_text: mounted on the usual star wheel shaft D' toothed wheels D¹ driving each of the
rollers A while toothed wheels D' of greater diameter than the wheels D¹ are
mounted to drive the cylinders C, so that in this arrangement the fabric a travels
quicker than the cylinders C. The mandril of each. engraving roller C is retained
in proper position by means of a bridge piece c, adjustable brass bearing c¹, pinching
screw and washers and tapered pins at c³.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. The method of, and arrangement of the parts of cylinder printing machines
for printing shaded, clouded, and like effects on calico and other web fabrics by
engraved printing cylinders all substantially as herein described.
Second. For printing shaded, clouded, and like effects on calico and other web
fabrics the combination with cylinder printing machines of engraved rollers driven
at a rate of speed different from that of the fabric being printed all substantially
as herein described.
Third. For printing shaded, clouded, and like effects on calico and other web
fabrics the combination with cylinder printing machines, of engraved rollers fitted
out of contact with the "bowl" and driven at a slower speed than the fabric being
printed; all substantially as herein described and illustrated by the accompanying
drawings.
