I GEORGE ASHLEY WILSON of Broad Green near Liverpool in the County
of Lancaster, Engineer, do hereby declare the nature of this invention for
"IMPROVEMENTS IN APPARATUS FOR FOLDING AND CUTTING PAPER IN ROTARY
WEB PRINTING MACHINES to be as follows:-
"
The object is to enable a web of paper as it is passing from a rotary web
printing machine to be folded transversely, and at the same time be cut through
the folded edge so as to be carried forward to additional folding or delivering
apparatus as two superposed sheets.
In carrying my invention into practice I make use of folding cylinders one of
which is provided with a gripping blade, and the other with a creasing and cutting
blade and gripper for carrying forward the leading edge of the web in combination
with printing and impression cylinders or retaining rollers. The gripping blade
and the creasing and cutting blade are fitted within slots in their respective
cylinders, and arranged to project equally or nearly so beyond the peripheries
of their respective cylinders, one cylinder being provided with a projecting lip
with which the gripping blade acts, and the other with a depression to receive
the said lip. The blades are secured in position and provided with connections
in the usual manner. A cutting blade severs the web into sheets in the usual way.
The action is as follows:-The leading edge of the web is carried by the leading
edge gripper around its cylinder until the creasing and cutting blade forces the
web between the gripping blade and lip and severs or perforates the web trans-
versely. The folded and severed edges are then carried forward by the gripper
blade to take off apparatus; the leading edge gripper then leaves hold of the web
and seizes a new leading edge obtained by the severance of the web by the second
cutting blade above mentioned.

I GEORGE ASHLEY WILSON of Broad Green near Liverpool 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:→
The object is to provide apparatus for folding transversely a web of paper as it
is passing from a rotary web printing machine and for at the same time cutting
through the folded edge so that the sheet is carried forward to additional folding
or delivering apparatus as two superposed sheets.

In carrying my invention into practice I make use of folding cylinders one of
which is provided with a gripping blade, and the other with a creasing and cutting
blade and with a gripper for carrying forward the leading edge of the web in
combination with printing and impression cylinders or retaining rollers.
gripping blade and the creasing and cutting blade are fitted within slots in their
respective cylinders, and are arranged to project equally or nearly so beyond the
peripheries thereof. One cylinder is provided with a projecting lip with which
the gripping blade acts and the other with a depression to receive the said lip.
The blades are secured in position and provided with connections in the usual
manner. A cutting blade severs the web into sheets in the usual way.
On the sheet of drawings herewith an end view is given of apparatus for carrying
my invention into practice. a a¹ folding cylinders, the cylinder a is provided with
a gripping blade b hinged at c and receiving oscillating motion to the slot d having
projecting lips by means of the slotted lever e and gear f. The cylinder a¹ is
provided with creasing and cutting blades gh, the blade g is pivotted at hand
projects through the slot i beyond the circumference of the cylinder a¹, the blade h
is carried in elastic bearings ; of any usual construction, the said cylinder a¹ is also
provided with a gripping blade 6 pivotted at c and receiving motion in the slot d
by gear ef. The slot d has not projecting lips. The cylinder a¹ bas depressions
therein to receive the lips d' as they pass the cutting and creasing blades. In
addition to the slot with lips d' on the cylinder a to receive the blade g there is
a second slot with lips k¹ to receive the blade h, and there is a creasing blade / to
act in conjunction with the gripper b on the cylinder a. pare rollers and tapes
bringing the printed web from the printing and impression cylinders or the web
may be delivered direct from the said cylinders to the cylinders aa¹.
The action of the apparatus is as follows:-When the end of a web enters
between the cylinders a a¹ the leading edge is caught by the gripper b on the
cylinder a¹ acting in conjunction with the creaser on the cylinder a in the usual
way when the cylinders a a¹ have rotated until in the position shown in the
drawing the leading edge is at b on cylinder a¹ whilst the centre is being forced
by the blade g between the lips & and gripper b on the cylinder a. In addition to
forcing the centre of the sheet between and b the blade g severs the web at the
centre. Further motion of the cylinders a al causes the two edges of the severed
sheet held by the gripper b on the cylinder a to be carried forward until they reach

page_text: the position ¹ at this time the web is severed by the blade h acting in conjunction
until the slot k, and the superposed sheets receive a second fold by means of the
folding blade m on a which acts, in conjuuction with the gripper n on a third
cylinder o or the superposed sheets may be carried away to other mechanism for
giving the second fold. Recesses q are made in the cylinders a a¹ to allow the
projecting blades and lips to pass.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
First. In combination with rotary web printing machines, apparatus for folding,
and at the same time cutting off sheets of paper, substantially as set forth.
Second. In combination with rotary web printing machines, apparatus for
folding, and at the same time cutting off superposing and delivering sheets of
paper.
Third. The combination with rotary web printing machines of two cylinders one
of which is provided with a gripping blade and the other with a creasing and
cutting blade substantially as set forth.
