The cylinder l1, hereinafter termed the collect
ing and tucking cylinder, is provided with a cor
responding number of cutting rubbers 35 to coop
erate with the knives 3|, 32 and 33 of the cylin
der "5. This cylinder is also provided with col
lecting and carrying means herein shown as
swingable pin points 36, 3‘! and 38 suitably
adapted and operable to collect and carry the
sheets cut by the aforesaid knives, and with a
10 tucking blade 4| suitably operated to cooperate
with a sheet folding jaw 42 provided on the cylin
der l8. The cylinder I3, hereinafter termed the
folding and transfer cylinder, is provided with
carrying means herein shown as swingable pin
15 points 43 and 44 whereby sheets from the pin
points 31 and 38 respectively are transferred and
carried to the guide rollers l9. It is to be under
stood that in place of the pin points shown, other
means adapted to carry the signature may be
20 provided, such as the well known grippers.
It is to be understood that the above men
tioned pin points 36, 3'! and 38 in the tucking
cylinder I‘! and the pin points 43 and 44 in the
folding cylinder l8 are adapted to be released
25 from the usual means causing their swinging
movement in timed relation with the rotation of
the respective cylinder. It is also to be under
stood that the tucking blade 4! in the cylinder l‘!
and the cooperating jaw 42 in the cylinder l8
30 may also be readily. caused to be inoperative by
releasing them from the effect of their usual ac
tuating means.
_
The arrangement provided by this invention is
such that when it is desired to produce signatures
35 having closed heads, the alternately acting cut
ting knives 32 and 33 in cylinder IS are caused to
be inoperative by entirely removing them from
the respective pocket, 34, the cutting knife 3!
being retained in its pocket 34 in operative con
40 dition. ,The operation of the alternately acting
pin points 3‘! and 38 in cylinder [1 is prevented
while the alternately acting, pin point 36 and the
tucking blade 4|, are retained in operating con
dition. The operation of the alternately acting
pin points 43 and 44 in cylinder I8 is prevented
45
and the jaw 42 is retained in operating condition.
In view of the above described arrangement,
which is illustrated in Figure 3, the webs | 2 feed
ing between the cylinders Ill and I‘! are cut into
sheets of double page length by the blade 3| , act-r‘
50 ing against the rubber 35, collected and carried
by the pin- point-36 about the cylinder H, and
tucked into the jaw 42 by the tucking blade 4|.
55
The jaw 42 grips the sheets as well as folds them
the ?rst time and carries them in once folded
condition to the guide rollers l9 whereby they are
disposed in the path of the vertically reciprocat
ing chopper blade 22, which directs them between
the folding rollers 23 and 24 for the second fold,
which, in the particular instance illustrated, is at
60 right angles to the ?rst fold,
3'] and 38 about the cylinder |'|, engaged by the
pin points 43 and 44 in the cylinder l8, and there
by delivered to the rollers IQ for disposition be
neath the chopper blade 22 to be folded only once
as above described.
By the use of the pin points 36, in the ?rst ar
rangement as shown in Figure 3, and the pin
points 31 and 38, in the arrangement as shown in
Figure 4, the cylinder I‘! may be operated to col
lect a plurality of sheets if such operation thereof 10
is required, by operating the tucking blade 4| and
the jaw 42 only on every second, third or other
alternate revolution, and correspondingly chang
ing the operation of the pins 36, so a plurality of
sheets will be collected before they are trans 15
ferred to the cylinder |8.
It will be understood that the invention may be
embodied in other speci?c forms without depart
ing from the spirit or essential attributes thereof,
and it is therefore desired that the present em 20
bodiment be considered in all respects as illus
trative and not restrictive, and it will be further
understood that each and every novel feature and
combination present in or possessed by the mech
anism herein disclosed forms a part of the inven 25.

knives may be either collected by a pin point on
said second cylinder, engaged and folded by co 45"
operation of said tucking blade thereon and the
jaw on said third cylinder, or cut from the web by
others of said knives, collected by others of the
pin points on said second cylinder, and trans
ferred therefrom by the pin points on said third
cylinder.
