IMPROVEMENTS APPLICABLE TO ROTARY WED PRINTING MACHINES FOR FACILITATING
FOLDING, DELIVERING AND COUNTING SHEETS OF PAPER,
My present invention relates to collecting folding and delivering in piles or
batches of any desired number sheets of paper from a rotary web printing machine
after they have received one or more transverse folds usually two by means of
folding cylinders or equivalent devices.
The main objects are to simplify the mechanism and render it more efficient,
expeditious and reliable in action.
The speed at which newspapers may be printed on rotary web printing machines
is limited by the speed at which the so called crossfold can be given to the sheets
after they issue from the transverse folding mechanism. Hitherto it has been
attempted to overcome the difficulty by causing the transversely folded sheets to
be directed into two or more streams each leading to cross folding apparatus.
Now the first part of my invention provides means whereby cross folding may
be effected on one apparatus and with the sheets following each other in a single
direction only and without being divided into streams. The apparatus is thereby
greatly simplified and the use of multiple sets of tapes and folding apparatus is
avoided
For the above purpose I collect the printed sheets after they have received one
or more usually and preferably two transverse folds, in series close together following

page_text: each other and then transmit such series of papers at regular intervals to the cross
folding apparatus to be cross folded. The speed at which the cross folding mechanism
is worked to fold a given number of sheets is reduced and the required machinery
or apparatus occupies less space.
One apparatus for carrying the above first part of my improvements into effect
is constructed as follows: Endless tapes or their equivalents moved at a constant
speed convey the papers from transverse to cross folding mechanism and stops
grippers or other suitable devices are arranged to arrest one two three or more
sheets consecutively until they are all close to each other. The stops grippers or
other suitable devices are then moved so as to liberate the series of sheets and permit
them to be carried forward at the same time to cross folding mechanism which is
or may be of any suitable kind.
Under the second part. Papers after being cross folded are collected and delivered
in piles of suitable number by means of the following novel combinations of
mechanism receiving motion at the required times by means of any well known
or suitable intermittent gearing
(a) The folded papers are deposited by means of a fly or in any known or
suitable manner on an inclined table and after a pile containing the desired number
of papers has been made a vibrating or oscillating fly operated by cams or other
suitable means gives motion to the pile of papers and carries them to a second
table.
(b) The papers are deposited on a table and are brought into contact at the desired
intervals with continuously moving tapes. Lever or equivalent mechanism is
provided for raising the tapes or lowering the table.
(c) The papers are retained on the table by means of a stop or stops in contact
with continuously moving tapes until the desired pile is made. The stop or stops
is or are then removed and the pile of papers is carried away by the tapes.

GEORGE ASHLEY WILSON of Liverpool in the County of Lancaster, Engineer
IMPROVEMENTS APPLICABLE TO ROTARY WEB PRINTING MACHINES FOR FACILITATING
DELIVERING AND COUNTING SHEETS OF PAPER
"
My present invention relates to collecting folding and delivering in piles or
batches of any desired number sheets of paper from a rotary wet printing machine
after they have received one or more transverse folds usually two by means of
folding cylinders or equivalent devices.
The main objects are to simplify the mechanis:n, and render it more efficient,
expeditious and reliable in action.
The speed at which newspapers may be printed on rotary web printing machines
is limited by the speed at which the so called crossfold can be given to the sheets
after they issue from the transverse folding mechanism. Hitherto. it has been
attempted to overcome the difficulty by causing the transversely folded sheets to
be directed into two or more streams each leading to cross folding apparatus.
Now the first part of my invention provides incans whereby cross folding may
be effected on one apparatus and with the sheets following each other in a single
direction only and without being divided into streams. The machinery is thereby
greatly simplified and the use of multiple sets of tapes and folding apparatus is
avoided.
.
•
For the above purpose I collect the printed sheets after they have received one
or more usually and preferably two transverse folds, in series close together following
each other and then transmit such series of papers at regular intervals to the cross
folding apparatus to be crossfolded. The speed at which the cross folding mechanism
is worked to fold a given number of sheets is reduced and the required machinery
or apparatus occupies less space.
One apparatus for carrying the above first part of my improvements into effect
is constructed as follows:-Endless tapes or their equivalents moved at a constant
speed convey the papers from transverse to cross folding mechanism and stops
grippers or other suitable devices are arranged to arrest one two or more sheets
consecutively until they are all close to each other. The stops grippers or other
suitable devices are then moved so as to liberate the series of sheets and permit
them to be carried forward at the same time to cross folding mechanism, which is
or may be of any suitable kind.
Under the second part. Papers after being cross folded are collected and
delivered in piles of suitable number by means of the following novel combinations
of mechanism receiving motion at the required times by means of any well known
or suitable intermittent gearing.
(a) The folded papers are deposited by means of a fly or in any known or
suitable inanner on an inclined table and after a file containing the desired number
of papers has been made, a vibrating or oscillating fly operated by cams or other
suitable means gives motion to the pile of papers and carries them to a second
table.
(b) The papers are deposited on a table and are brought into contact at the desired
intervals with continuously moving tapes. Lever or equivalent mechanism is
provided for raising the tapes or lowering the table.
(c). The papers are retained on a table by means of a stop or stops in contact
with continuously moving tapes until the desired pile is made. The stop or stops
is or are then removed and the pile of papers is carried away by the tapes.

Fig 1 is a side elevation, and fig 2 an end elevation of apparatus illustrative of
the first and second parts of my invention. 1 frame of printing and folding
machine. 2 transverse folding roller, 3. 4. 5. 6. 7. 8. 9. 10. 11 carrying rollers for
tapes 12, 13 carrying rollers for tapes 14, 15, 15, 15b are fixed stops; on the
cranked arms 16 pivotted at 17 and connected by rods 18 to the
cam, 19 arc
lifting pieces 16ª, 20 cross folding rollers, 21 stops on levers 22 coupled by the
connecting rods 23 to the cam 19, 24 take off tapes from the cross folding
apparatus, 25 laying fly actuated by levers and rods 26 from the gearing 27 which
gives motion by the levers and rods 28 to the cross folding blades 29. 30. 31
inclined tables. The table 30 is pivotted at 32 and actuated intermittently by the
ratchet gear 33 operated from the levers 26 so as to lay the papers on the second
table 31 at the desired times.
The construction of the printing and folding mechanism and the means of
operating the same as also the arrangement of tape rollers tapes and the means of
actuating the flys are of any usual or suitable kind and are not of themselves
features of my invention but may be varied to suit different arrangements of my
improved collecting and delivering apparatus.
The action of the apparatus is as follows:-The papers leave the transverse
folding rollers and are carried forward by the tapes 12 with a distance between
them equal to the amount the sheets have been reduced in size by folding. The
first sheet travels forward until it is arrested by the stop 15. The lifting pieces
16 and 16b are then caused to fall in succession by the cam 19 so that the second
and third papers strike against the stops 15ª and 15, the fourth paper follows on
until it reaches the third paper when the lifting pieces are simultaneously raised
by the cam and all the papers travel forward close together until they reach the
cross folding apparatus and are arrested simultaneously by the stops 21. The cross
folding apparatus crossfold the papers during the time that a second series of papers
are being collected by the tapes 12. The rollers 10. 11 allow of the tapes 12 being
run a slight distance apart so as not to cause too great a friction on the papers
whilst they are at rest. Instead of the stops being fixed and lifting pieces being
used to raise the tapes and so allow the papers to pass the stops at the desired
times, movable stops may be used for that purpose.
'
The sheets as delivered from the cross folding apparatus are laid one after the
other on the inclined table 30 by the fly 25. After a certain number of papers
determined by the number of ratchet teeth in the driving gear have been deposited
on the said table 30, the said table is caused to make a partial revolution on its
bearings and deposit the pile of collected papers on the stationary inclined table 3.1
whence they are removed from time to time.
Fig 3 is a side elevation of apparatus illustrative of the second part of my
invention and is a modification of the delivery apparatus shown in figs 1 and 2;
here both the inclined tables 30. 31 are stationary and the papers are deposited on
the table 30 by the take off tapes 24 and when a sufficient number have been filed
the pile is removed by the fly 25 on to the table 31. The fly 25 is actuated by
ratchet gear 26 so as to move once after any number of sheets are piled, that number
being determined by the teeth of the ratchet gear. Any other suitable intermittent
gear may be used.
Fig 4 is an elevation of a further modification of apparatus under the second
part; here the sheets are deposited by a fly 25 on continuously running tapes 34
and are held in position by stop 35. When the desired number of sheets have been
piled the stop 35 is lowered by means of intermittent gearing such as is shown in
the drawings or similar gear further description being unnecessary, as gear of this
description is well known and in common use for various purposes.
Instead of a stop being lowered the tapes may be raised and brought into contact

page_text: with the papers at the desired times by means of lifting pieces as shown in figs 1
and 2.
