IMPROVEMENTS IN ROTARY APPARATUS FOR FOLDING SHEETS OF PAPER
Year: 1885

page_text: I GEORGE ASHLEY WILSON of N° 4 Clayton Square Liverpool in the County
of Lancaster Engineer do hereby declare the nature of the said invention for
"IMPROVEMENTS IN ROTARY APPARATUS FOR FOLDING SHEETS OF PAPER" to be as
follows:-
0
.
The object is to provide for use mainly with rotary web printing machines
simple apparatus easily adjusted to fold correctly and centrally papers of various
sizes twice or oftener so that the same machine may be used for several sizes of
papers.
The invention consists essentially in employing in combination with two or more
Cylinders provided with folding blades and grippers constructed and actuated in
the usual or any suitable manner an adjustable roller or rollers and tapes whereby
the distance travelled by the papers from the first set of folding blades and grippers
to the second set of folding blades and grippers may be lengthened or shortened―
The adjustable roller or rollers is or are carried in bearings movable in guides or on
links or equivalent devices and the tapes are led from one set of folding Cylinders
around such rollers to a second set of folding Cylinders-when there is one
adjustable roller only elastic tapes are used.
The action of the apparatus is as follows-The Sheets of papers after being cut
are led to the first folding Cylinders which have been adjusted by gearing so as to
fold the Sheets in the required place, the folded Sheets then travel along the
adjustable tapes until they reach the second set of folding Cylinders one of which
may be a Cylinder of the previous set-The tapes are so adjusted that when the
folded papers reach the second set of Cylinders they are folded centrally.

I GEORGE ASHLEY WILSON of N° 4 Clayton Square 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 for use mainly with rotary web printing machines
simple apparatus easily adjusted to fold correctly and centrally papers of various
sizes twice or oftener so that the same machine may be used for several sizes of
papers.
The invention consists essentially in employing in combination with three or
more cylinders provided with folding blades and grippers constructed and actuated
in the usual or any suitable manner, adjustable rollers and tapes whereby the
distance travelled by the papers from the first set of folding blades and grippers
to the second set of folding blades and grippers may be lengthened or shortened..
The adjustable rollers are carried in bearings movable in guides or on links and
the tapes are led from one set of folding cylinders around such rollers to a second
set of folding cylinders.
The drawing appended hereto shows in outline the position and proportions of
apparatus suitable for carrying my invention into effect." a portion of the frame of
a printing machine bb₁ b³ are cylinders provided with folding blades and grippers
constructed and arranged in the usual and now well known manner to give two
transverse folds to the web of paper passing between them. c distance regulating
roller carried by the lever d pivotted at e and adjusted as to position by the
connecting rod and nut wheels f, h carrying rollers i elastic tapes passing round
the rollers c and 'h.
The action of the apparatus is as follows:-
The sheets of paper after being cut are led to the first folding cylinders 6 61
which have been, adjusted by gearing to fold the sheets in the required place.
The folded sheets then travel along the tapes & around the rollers c h until they
reach the second set of folding cylinders b¹ b². The distance travelled from the
cylinders b 61 to 61 62 is such that a correct second fold is made: if the papers are
larger the roller c is moved further from the cylinders 6 62: if the papers are
smaller the roller c is moved nearer to the cylinders 6 6¹. When it is not desirable
to use elastic tapes two rollers ch must be made adjustable say the rollers and h*
so that as the roller c recedes from cylinders b b' the roller h* approaches them.
Instead of the cylinder 'b' serving for both the first and second folds an additional
cylinder may be used for the second fold.

page_text: 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
First. The improvements in rotary apparatus or appliances for folding sheets of
paper substantially as herein set forth.
Second. The combination with three or more cylinders provided with folding
blades and grippers, of adjustable rollers and tapes substantially as set forth.
