Improvements in Web Printing Machines.
Year: 1898

page_text: I, FRANCIS FOSTER, of Bow Lane Iron Works, Preston, in the County of Lan-
caster, Engineer, do hereby declare the nature of this invention to be as follows:
My invention relates to a construction and arrangement of the parts of a web
printing machine so that while it occupies comparatively small floor space it
can print perfect and fold a great number of sheets in a given time.
For this purpose, I make the machine in two storeys each storey containing
substantially the same parts which are arranged as follows:-
At the end is the paper roll whence the web is conducted by guide rollers so
as to pass between a set of inkers below it and a set of inkers above down
between the first forme and impression cylinders, under the latter then up and
horizontally between the second forme and impression cylinders by which the
printing is perfected. The inkers above which the web passes, serve for the first
forme cylinder, those under which the web passes, and which are to a certain
extent inverted serve for the perfecting forme cylinder. The perforated webs
from both storeys are led over separate folding apparatus of known kinds. The
machine may be made to take webs of double width, either or both of which can
be longitudinally divided after the printing and before the folding.

Improvements in Web Printing Machines.
I, FRANCIS FOSTER, of Bow Lane Iron Works, Preston, in the County of Lan-
caster, Engineer, 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 a construction and arrangement of the parts of a web
printing machine so that, while it occupies comparatively small floor space it
can be applied to print perfect and fold in a given time a great number of
sheets, either singly or so as to deliver publications of various numbers of pages
as required for newspapers and the like.

page_text: Figure 1 of the accompanying drawings is a diagrammatic elevation and
Figure 2 is a plan of a pair of printing machines according to my invention
arranged in combination with a pair of folders for operating as above indicated.
Figures 3 and 4 are respectively an elevation and a plan (shewing a modification.
Referring to Figures 1 and 2, each printing machine has two reels delivering
webs A and B, each of which after passing between a set of lower inking rollers
Rand upper set R³, passes between the lower forme and impression cylinders F¹ PI
then between the upper forme and impression cylinders F2 p2 by which
it is perfected. By the printing mechanism in the upper storey, which is exactly
similar to that in the lower storey, another web is perfected. The printed
webs A and B may be diverted by turners TT, folded lengthwise by formers X'X2
cut and cross folded by apparatus at C and delivered at D, the turning
folding, cutting and delivery mechanism being of the usual known kind. Thus
two separate sets of folded printed matter may be delivered, one set from each
storey of the machine, or by suitably arranging turners and guide 'rollers the
webs from both storeys might be folded cut and delivered together, presenting
double the number of pages. Further, either of the webs might be longitudinally
divided, half of the one joining the other whole web. The one machine may be
used alone, or along with the second two storey machine which is exactly similar
but to the opposite hand, delivering two perfected webs A and B which may be
turned, folded cut and delivered separately or together. Also by suitably ar-
ranging turners and guide rollers, either or both the webs from the one machine
might be folded, cut and delivered with either or both of the webs from the other
machine, in which case the machines are necessarily geared together so that the
webs from both travel at exactly the same speed.
As shewn in Figures 3 and 4 the printing machines of the lower storeys have
their cylinders arranged vertically while those of the upper storeys have them
arranged horizontally. The two folding machines are placed to face each other
and the diverting rollers are dispensed with the webs A and B being folded
together and the webs A and B being folded together.
The mechanism for driving the forme and impression cylinders, the inkers and
the folders being all of the usual known kind, I have not thought it necessary
to describe them, nor do I make any claim in respect of them.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-.
A two-storey web printing machine, having its reels, inkers and cylinders ar
ranged and operating substantially as described with reference to the drawings.
