The interchangeable half member 21
has a semicircular groove 3!] matching with the
groove 29 and having an offset portion 3!. ‘The
interchangeable half member 28 is provided with
a semicircular groove 32 matching with the
groove 29 in the common half member 26. This
groove 32 is concentric with the shaft 25.
_,
When it is desired to control the action of
sets of normally projecting impaling pins l1 and
IS on the collecting and folding cylinder l6 at
their sheet taking point the rotary cam members
26 and 2'! are used. A movable cam 33 is brought,
into and out of its position to engage the rollers
34, 35 of the sets of disappearing impaling pins
15 I1 and I8 by providing the movable cam 33 with
a stud or roller 36 which travels in the cam
groove 29, 30, 3|. When it is not desired to con
trol the action of the sets of disappearing im
paling pins l1 and I8 at their sheet taking point
20 the cam members 26 and 2B are used and the
cam 33 is thereby held out of its operative posi
tion as its stud or roller travels in the concen
tric cam groove 29, 32. A movable cam 31 con
trols the sets of disappearing impaling pins I1
25 and I8 on the collecting and folding cylinder Hi
to permit the signatures to be folded off onto
the folding and delivery cylinder’ 22. This mov
able cam 31 is provided with a stud or roller 38
which travels in the groove 39 of a rotary box
30 cam 40 mounted on the shaft 4| of the said cyle
inder 22, said groove 39 having an offset por
tion 42.
A stationary cam 43 is arranged in position to
engage the stud or roller 44 of the folding jaws
35 2! on the folding and delivery cylinder 22 to open
the stud or roller 60 of said folding jaws. An
other ?xed cam BI is arranged to engage the
said stud or roller 5!! to open the jaws to deliver
the signatures to the packer delivery 23.
A laterally movable cam 62 of well known or
approved form is arranged to be brought into
and out of the path of the studs or rollers 56,
51, 58 to withdraw the three impaling pins l0, II
and I2 to transfer the entire product to the col
lecting and folding cylinder [6 or to withdraw 10
a selected two of these pins when one-third of
the product is to be transferred to the folding
and delivery cylinder l5.
In the embodiment of the invention shown and
described herein'the operation is as follows:
15
The full forty-eight page product of the press
_ is collected, folded and delivered in any of the
following combinations, to wit:
Four eight page signatures to delivery 24 and
four four page signatures to delivery 23; or four 20
twelve page signatures to delivery 24; or two six
teen page signatures to delivery 24 and two eight
page signatures to delivery 23; or two twenty
four page signatures to delivery 24; or one thirty
two page signature to delivery 24 and one sixteen 25
page signature to delivery 23.
When the full web four pages wide is to be
collected, folded and delivered, the web is cut
into three sheets each'cycle of the press. When
the web is slit into two narrow webs two pages 30
wide the two webs are combined and then cut
into three pairs of sheets each cycle of the press.
When the web is slit into four narrow websone
page wide the four narrow webs are combined

and cut into three groups of four sheets each, 35
each cycle of the press.
When four eight page signatures are to be de
livered to the delivery 24 and four four page
signatures to the delivery 23, the web four pages
wide is fed between the rotary cutter 3 and the 40
cutting and folding cylinder 4. The cams 33 and
62 are operated so that the ?rst and third sig
natures are taken by the impaling pins I’! on
l5, which box cam comprises a common half
45 member 41 and two interchangeable half mem
bers 48 and 49. The common half member 41
has a semicircular cam groove 50 concentric with
the collecting and folding cylinder I6. The two
superimposed signatures on the cylinder I Gare 45
folded off onto the folding and delivery cylinder
22 and they are slit‘ longitudinally by the slitters

4-8 has a semicircular groove 5! matching with
50 the groove 50 and having an offset portion 52.
jecting impaling pins In, H and J2 on the cut
63 into four eight page signatures and then de
posited onto the delivery 24. The second signa
ture is folded o? from the cylinder 4 onto the 50
folding and delivery cylinder- l5 and there slit
longitudinally by the slitters 64 into four four
page signatures and then deposited onto the de
livery 23.
Where four twelve page signatures are to be 55
delivered to the delivery 24 the web four pages
ting and folding cylinder 4 at their sheet trans
wide is cut on the cylinder 4 and collected alter
the jaws to receive the signatures from they col
lecting and folding cylinder 15. Another sta
tionary cam 45 is arranged in position to en
gage the stud or roller 44 of the folding jaws 2|
40 to open the jaws at the proper point to deliver
the signatures to the delivery 24.
A changeable rotary box cam is mounted on
The interchangeable half member 49 is provided
with a semicircular groove 53 matching with the
groove 50 in the common half member 41 and
concentric with the shaft 46. When it is desired
55 to control the action of the sets of normally pro
fer point, the rotary cam members 41 and 48 are
used. When it is not desired to control the ac
60 tion of the said sets of impaling pins H], II and
I2 at their transfer point the cam members 41
and 49 are used.
The movable cam for con
trolling the action of these disappearing impaling
pins [0, H and i2 is denoted by 54,‘ which mov
65 able cam is provided with a stud or roller 55
traveling either in the cam groove 50, 5|, 52 or
the cam groove 50, 53, as the case may be. This
movable cam 54 is arranged, when operating, to
successively engage the studs or rollers 56,, 51
and 58 on the impaling pins I0, II and I2 respec
tively.
A ?xed cam 59 is arranged in position to open
the jaws M on the folding and delivery cylinder
i5 to coact with the folding blade l3 of the cut
75 ting and folding cylinder 4, said cam 59 engaging
nately by the pins I‘! and I8 on the cylinder l6
until each set of pins has a signature of three
sheets. These signatures are folded off onto the 60
folding and delivery cylinder 22 and there‘ slit
longitudinally by the slitters 63 into four sig
natures of twelve pages each and then deposited
onto the delivery 24.
Where two sixteen page signatures are to be
delivered to the delivery 24 and two eight page
signatures to the delivery 23, the web is slit
longitudinally into two narrow webs two pages
wide and superimposed before passing between
the rotary cutter 3 and the cutting and folding
cylinder 4. The cams 33 and 62 are operated so
that the first and third groups of sheets are
taken by the pins H on the collecting and fold

Where two twenty-four ‘ipa'ge signatures are
to be delivered tdtheidelivery 24, the'web is slit
longitudinally into two narrow webs two pages
wide and superimposed before passing them be
tween the rotary cutter 3 and cutting and fold
15 ing cylinder 4. These groups of sheets are then
taken alternately by the pins l1 and I8 on the
collecting and folding cylinder l6 until three col
lections are made on each set of pins. The
sheets are then successively folded off onto the
20 folding and delivery cylinder 22 and slit longi
tudinally by the slitters 63 into two twenty-four
page signatures and then deposited onto the
delivery 24.

Where one thirty-two page signature is to be
25 delivered to the delivery 24 and. one sixteen page
signature to the delivery 23, the web is slit longi
tudinally into four narrow webs one page wide
and superimposed before being passed between
the rotary cutter 3 and the cutting and folding
30 cylinder 4. The ?rst and third groups of sheets
are collected by the pins H on the cylinder l6
and the second group of sheets is folded off onto
the folding and delivery cylinder IS. The groups
of sheets on the cylinder I6 are folded off to
