page_text: Improvements in Web Printing and Folding Machines.
I, FRANCIS FOSTER, of Bow Lane Iron Works, Preston, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to the construction and arrangement of a web printing
machine in connection with folding machines in such a manner that a large
number of sheets can be printed, perfected and folded in a given time.
For this purpose, according to one arrangement I make the machine in two
storeys, each storey, containing substantially the same parts arranged as
follows:-
At the end is the paper roll whence the web is connected by guide rollers so
as to pass between a set of inkers below it and a set of inkers above it 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 perfecting webs from both storeys are led over two triangular formers of
the known kind by which sheets are folded in two longitudinally.
The machine may be made of such width as to take webs of double the usual
width, either or both of which can be longitudinally divided after the printing
and before the folding.
According to another arrangement, especially adapted for printing two journals
at a time each of 6 pages, three complete perfecting machines each consisting of
the same parts similarly arranged are combined in three storeys.
Two of these deliver sheets each of 4 pages and the third delivers half sheets
each of 2 pages.
At the delivery end of the machine are arranged two triangular formers of
the known kind by which sheets are folded in two longitudinally, one of these
formers is beyond the other, but both face the same way, and one of these may
be inverted, or, according to a modified arrangement, the two longitudinal formers
mav be placed so as to face each other.
By means of guide rollers the sheets and half sheets are led to the two folding
formers, one of the sheets and one of the half sheets to each, so that from each
folding former a journal of 6 pages is delivered, the half sheet being folded within
and not outside the full width sheet.

I, FRANCIS FOSTER, of Bow Lane Iron Works, Preston, in the County of
Lancaster, 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:-
-
This invention relates to the construction and arrangement of a web printing
machine in connection with folding machines in such a manner that a large
number of sheets can be printed, perfected and folded in a given time.
For this purpose I construct and arrange the machines as I shall describe, by
way of example, for printing and folding two journals each of six pages at the
same time.
Figure 1 of the accompanying drawings is a diagrammatic side view of the
printing machine and a pair of longitudinal folders acting in connection with
it, and Figure 2 is an end view of the folders.
Figure 3 is a side view and Figure 4 is an end view of a modified arrangement
of the folders. Figures 5 and 6 are corresponding views of another modification.
Figure 7 is a side view and Figure 8 is a plan of a further modification.
Referring first to Figures 1 and 2, the printing machine is made in three
equal superposed storeys each constituting a complete perfecting machine for
the webs A, B, C, respectively.
At the delivery end of the printing machine there are two of the known folding
machines F and F2 the latter being inverted. The web B is divided lengthwise
so that it issues from the printing machine as two webs B1 B2 each of half width.
The one half B₁ passes with the web A to the folder F2, A being first longi-
tudinally folded by the triangular former, but B' being merely diverted at right
angles by one side of the former.
In like manner the other half web B accompanies C to the folder F¹ where
it is diverted while C is longitudinally folded.
The folders may be arranged both facing one way as shewn in Figures 3 and 4,
the web A being divided into halves A¹ and A2 folded along with C while B is
folded by itself. Or, as shewn in Figures 5 and 6 the folders may be placed
facing each other, the one half web A¹ being folded with B and the other -A³
being folded with C.
As shewn in Figures 7 and 8, C is longitudinally divided one half C¹ being
folded with B and the other C³ being folded with A.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The combination of a three storey perfecting printing machine with two
folding machines, substantially as and for the purpose set forth.
