PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Feeding Successive Sheets from a
Paper Web.
We, JOSEPH FOSTER, FRANCIS FOSTER and JAMES YATES FOSTER, all of
Bow Lane Iron Works, Preston, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention relates to mechanism for severing successive sheets of paper from
a web for the purpose of supplying them to a printing machine or conveying
printed sheets to a folding machine or collecting device.
For this purpose we provide a pair of cutting cylinders which, at any required
length of sheet, perforate the web without severing it, but leave the connection
strong enough for the paper to be carried to a second pair of cylinders which
operate as breaking cylinders.
One of these cylinders has a slot, the other has a projecting tooth; they are so
timed by gearing to the cutting cylinders that the perforated part of the web as it
passes between them comes over the slot and the projecting tooth entering the slot
entirely severs the sheet from the web.
The forward edge of the sheet is seized by grippers at the time when its hinder
edge is released by the severing operation.
In some cases, when the sheet has to be fed to a folding machine, it is released
by the severing operation, the grippers in that case seizing the front edge of the
web behind it.

Improvements in Apparatus for Feeding Successive Sheets from a
Paper Web.
We, JOSEPH FOSTER, FRANCIS FOSTER and JAMES YATES FOSTER, all of
Bow Lane Iron Works, Preston, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention and in what manuer the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
Our invention relates to mechanism for severing successive sheets of
paper from
a web for the purpose of supplying them to a printing machine or conveying printed
sheets to a folding machine or collecting device.
For this purpose we arrange apparatus as we shall describe referring to the
accompanying drawings,
Fig. 1 being a vertical section and Fig. 2 a plan of apparatus for severing and
feeding sheets to a printing cylinder.
Figs. 3 and 4 are respectively a section and plan of an apparatus for severing
printed sheets and delivering them to a folding cylinder.

page_text: Referring to Figs. 1 and 2, A is the roll of paper web, B are a pair of drawing
rollers, C are a pair of cutting cylinders which at each revolution perforate the web
without severing it, but leave the connection strong enough for the paper to be
carried to a second pair of cylinders which may be merely segments D as shewn,
and which operate as breaking cylinders.
One of these segments has a slot, the other has a projecting tooth; they are so
adjusted in position by screws d and timed in relation to the cutting cylinders C
and the printing cylinder E that the perforated part of the web as it passes between
them comes over the slot, and the projecting tooth entering the slot entirely severs
the sheet from the web.
The forward edge of the sheet is seized by grippers F on the impression
cylinder E at the time when its hinder edge is released by the severing operation.
Referring to Figs. 3 and 4, C are the cutting cylinders and DD¹ are the
severing cylinders one of which D' has a set of grippers G, which when the sheet
is released by the severing operation, seize the front edge of the web behind. The
cylinder D has also a folding knife H which presses the middle of the severed
sheet into the slot of the folding cylinder F where it is held by grippers K.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we claim, in
respect of apparatus for feeding successive sheets from a paper web, is :—
1. The combination of a pair of cutting cylinders and a pair of severing cylinders
or segments of cylinders with feeding rollers and a printing cylinder provided with
grippers, substantially as described with reference to Figs. 1 and 2.
2. The combination of a pair of cutting cylinders and a pair of severing cylinders
with a folding cylinder, substantially as described with reference to Figs. 3 and 4.
