Apparatus and method for handling jackets of printed matter

An inserting machine is provided with mechanisms which allow it to operate in conjunction with a rotary printing press. In a preferred embodiment, the inserting machine is driven synchronously by the press and is fed newspaper jackets directly from the printing press without the need for intervening jacket feeders or stackers. A diverting mechanism which oscillates is positioned previous to the shingling operation of the press folder to divide the single press stream into multiple streams by diverting alternate jackets to different conveyors which are driven at a slower throughput. The divided streams of jackets are transported via the conveyors to an inserting machine which has two inserting lines arranged in a tandem configuration in order to insert at double the speed of a single line inserter and also in order to compensate the folds in the stacks and to output a bundle rather than a stream.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The invention relates to apparatus and methods for feeding jackets of 
printed matter into inserting machines and the related feeding of inserts 
into the jackets to form finished products which are compensated and 
stacked to form bundles. In an illustrated embodiment, the invention 
relates to the feeding of inserts into newspaper jackets produced on a 
rotary printing press. 
2. Description of the Prior Art 
In the assembly of printed matter for distribution, it is often desirable 
to insert one type of printed matter within another to form the finished 
product. In particular, it is desirable to have an efficient means for 
feeding inserts into jackets, for example, feeding advertisements or 
so-called Sunday supplements, into a newspaper jacket. 
As is well-known in the art, the printed web on a rotary printing press 
moves to a folding cylinder where it is cut, folded and then deposited by 
a flyer drum on a conveyor belt. The conveyor belt carries the complete 
product in a single stream of overlapped or shingled jackets. According to 
present practice, this stream is conveyed away from the press and then 
stacked into bundles either by hand or by a machine known as a stacker. 
In instances where an insert is not desired, the stack or bundle is simply 
delivered to the loading dock. However, where it is desired to feed 
inserts into the newspapers jackets, the jackets must be taken out of the 
bundled state and "individualized" at a jacket feeding station on an 
inserting machine. 
There are two distinct methods of operating inserting machines. In a first 
method, known as the "off-line" method, the stream of jackets coming off 
the press is transformed by hand or machine into a stack in one work area. 
The bundles are then transferred, usually by hand, to a second area where 
they are placed on a part of the inserting machine known as the jacket 
feeding station. This jacket feeding station individualizes jackets so 
that they may be opened, inserted, closed and delivered by the inserting 
machine which, according to prior art practices, produces a continuous 
shingled stream of inserted newspapers which must be again stacked and 
then compensated before being sent to the loading dock. 
In this off-line method, the printing and inserting operations are not 
coordinated; furthermore, two stacking operations are required, a great 
deal of labor is used to manually transfer bundles from one work area to a 
second one and the inserting machine must be equipped with a jacket 
feeding mechanism whose sole purpose is to "unstack" or "individualize" 
the bottom jacket in the stack. 
Despite its many disadvantages, the off-line system is the only system 
within the price range of many small and medium size newspapers. 
The past decade has seen the advent of "on-line" systems wherein the 
printing operation is partially coordinated with the inserting operation. 
In the on-line system, the jackets are conveyed from the printing press to 
the inserter in the shingled manner and then formed into stacks at the 
jacket feeding station. The jacket feeding station takes the bottom jacket 
from the stack and "individualizes" this jacket so that it may be fed into 
the inserting machine where it is opened to receive an insert. Although 
the jackets from the press are conveyed directly to the inserting machine 
jacket feeder without previously unloading it from the conveyor as in the 
off-line technique, the printing and inserting operations are not 
synchronized on a one-for-one basis. Because of this lack of 
synchronization, the typical on-line system requires a number of 
mechanisms to correct for underspeed or overspeed conditions of press vs. 
inserter and overflow gates which receive the jackets when there is a 
shutdown or when the inserter cannot keep up with the press. Furthermore, 
the on-line inserters require complex detecting devices to activate or 
deactivate the jacket supply conveyors during conditions when there are 
either too many or not enough jackets available at the jacket feeder. 
Thus, there is an acute need for a relatively simple and reliable apparatus 
and method for on-line feeding of jackets into inserting machines. 
SUMMARY OF THE INVENTION 
According to the present invention an inserting machine is provided with 
mechanisms which allow it to operate in conjunction with a rotary printing 
press. In a preferred embodiment, the operation of the inserting machine 
is fully synchronized with the operation of the press and is performed at 
the same speed. 
The apparatus includes a diverting mechanism which oscillates and is 
located previous to the shingling operation of the folder of the printing 
press. The diverting mechanism serves to divide the single press stream 
into multiple streams by deflecting alternate newspaper jackets as they 
travel through the folder to different conveyors which are driven at a 
slower throughput in order to be compatible with the speed of the 
inserting line to which each conveyor is connected. 
Every other jacket is directed to one path while alternate jackets are 
diverted at least to another one. Conveyor mechanisms comprising endless 
belts are adapted for holding the stream of newspapers therebetween. 
At some point prior to entering the inserting machine, the conveyors are 
driven at such speed so as to cause the jackets to be positioned in a 
spaced-apart or non-shingled manner which is compatible with the operation 
of the inserting machine. 
Since the multiple conveyors operate at the same speed as and are hooked 
directly to the inserting machine, the need for a jacket stacking and 
feeding operation is eliminated. 
The multiple conveyors terminate at an inserting machine which has a novel 
configuration of tandem, parallel inserting lines. At the tandem inserting 
machine the newspapers in each conveyor form two lines of spaced-apart 
newspapers. The tandem inserting machine includes an insert feeding 
station on each line where the single newspapers in each line receive 
inserts from insert feeder heads. 
After the insert feeding operation the two lines of newspapers are merged 
to form compensated stacks. Each compensated stack comprises two finished 
products with the fold line of one aligned opposite the fold line of the 
other. The stacks are then conveyed to a double bin stacking apparatus 
where they accumulate to form a compensated bundle of a predetermined 
number. The bundles are transferred to a roller top conveyor for delivery 
to a tying station and the loading dock. 
Thus the dual or tandem inserting lines in the inserting machine permit: 
(a) double the speed of a single line inserting machine; 
(b) compensated fold in stacks; and 
(c) bundles rather than streams. 
One feature of the invention is the provision of means for forming plural 
paths emerging from the press with each path comprising a conveyor that is 
directly associated with an inserting line. 
One aspect of this feature is that the jackets so conveyed have their 
shingling reduced by at least 100% when transforming the single path into 
multiple paths. 
Another feature of the invention is the provision of a tandem inserting 
machine having means for transporting two lines of spaced-apart newspapers 
to a pair of insert feeder heads and means for merging and compensating 
the finished products into stacks of two compensated products which join 
in stacking bins to form bundles. 
Yet another feature of the invention is the provision of means for directly 
driving the deflector mechanism and inserting machine by electrical and or 
mechanical connection to the printing press. One aspect of this feature is 
that the printing operation and the insert feeding operation are fully 
synchronized, i.e., for every newspaper exiting the press a newspaper is 
being fed an insert. Dry conditions and overflow conditions at the insert 
feeder stations are avoided.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, and in particular to FIG. 1, there is 
illustrated a portion of a conventional tucking blade folder of a rotary 
printing press to which a deflector mechanism 30 and auxiliary conveyor 32 
have been added in accordance with the present invention. The printing 
press includes a folding cylinder 12, a pair of last fold rollers 14, 16, 
a rotating flyer drum 18 and a conveyor mechanism 20. In operation, the 
conventional printing press forms newspaper jackets at the folding 
cylinder as indicated by newspaper jacket 56 in FIG. 1. This jacket is 
conveyed between last fold rollers 14, 16 and into a pocket 24 of flyer 
drum 18 which rotates in a clockwise direction as shown in FIG. 1. Each 
jacket is deposited from the pocket onto conveyor 20. According to prior 
art practices, conveyor 20 moves at such a speed that the jackets are 
deposited thereon in an overlapped or shingled manner. Operation of 
conveyor 20 at a speed high enough to prevent overlapping jackets is 
impractical at typical press outputs because the jackets will fly off the 
conveyor. 
In accordance with the preferred embodiment of the present invention, 
alternate newspapers emerging from last fold rollers 14, 16 are diverted 
from the flyer drum 18 by means of a deflector mechanism 30 and are 
conveyed to an auxiliary conveyor assembly 32. Deflector 30 is 
mechanically linked to the printing press so that it will automatically 
actuate at such times as to divert alternate newspaper jackets from 
receiving pocket 24. The jackets so diverted are directed to the auxiliary 
conveyor assembly 32. 
A first sprocket shaft 36 is mechanically linked to the axis 38 of flyer 
drum 18 to establish the direct press-drive of the deflector mechanism 30 
and auxiliary conveyor assembly 32. Although not illustrated, this 
mechanical connection may take the form of a chain-link or timing belt or 
other suitable mechanical linkage. The connection may also be electrical. 
First sprocket or pulley shaft 36 is connected to a second sprocket or 
pulley shaft 42 by means of a rubber timing belt or chain link 44. Shaft 
42 includes a cam 46 which actuates the deflector mechanism 30. As shown 
in FIG. 1, cam 46 is positioned to engage an associated cam follower 48 
which is secured to arm 49 which is, in turn, mounted on a shaft 50. Arm 
49 forms a substantially L-shaped assembly in conjunction with a first 
deflector blade 52. (Although only one blade 52 is illustrated in FIG. 1, 
shaft 52 mounts a plurality of identical blades 52 along its length). 
Thus, in operation, the rotation of cam 46 results in a back and forth 
motion of cam follower 48 which, in turn, causes deflector blades 52 to 
move into and out of the path of newspaper jackets exiting the last fold 
rollers 14, 16. First deflector blade 52 is shown in solid lines on FIG. 1 
in a non-interrupt position and in dashed lines in a diverting position. 
The size of the various sprockets or pulleys and the mechanical linkage to 
flyer drum axis 38 are chosen to cause the deflector blades 52 to move 
into the path of every other jacket exiting last fold roller 14, 16. The 
size of sprockets found on shafts 36, 42 and 50 have not been set forth 
and are believed to be well within the design capabilities of one skilled 
in the art. 
As shown in FIG. 1, each alternate diverted newspapers, for example 
newspaper jacket 56, falls by gravity onto a slide plate 58. Before 
reaching the end of slide plate 58, the leading folded edge of jacket 56 
is engaged by a timing spacer 60 which serves to break the downward 
movement of the jacket 56 and provide uniform spacing between the jackets 
entering auxiliary conveyor assembly 32. Timing spacer 60 moves downwardly 
after engaging the leading edge of jacket 56 and deposits the jacket onto 
a plurality of belts 62 which connect driven roller 64 and drive roller 
66. (Although not illustrated in FIG. 1, there are a plurality of parallel 
spaced belts 62 engaging rollers 64 and 66). Spacer 60 is mounted on a 
toothed timing belt 63 or chain link which is driven by shaft 36 and 
engages idler roller 65. 
After moving along conveyor 32, jacket 56 is also engaged on its upper 
surface by a plurality of parallel belts 70 (only one shown) which engage 
rollers 72, 74 and are intermediately engaged by roller 65. Thus, jacket 
56 is held by pressure between multiple parallel belts 62, 70 for 
conveyance in a predetermined spaced relationship to a desired location. 
As shown in the broken away portion of FIG. 1, belts 62 and 70 do not stop 
at rollers 66, 72 but continue, thereby forming an endless conveyor for 
transporting the jackets 56 which are held by pressure therebetween. 
In some applications of the invention the operator may wish to add inserts 
to only a portion of the total run of newspapers, for example, where 
regional advertising supplements are inserted into only a portion of the 
total run. In this situation it may be desirable to deactivate the 
deflector mechanism 30 at some point in the run, thereby allowing the 
complete output thereafter to be conveyed directly to flyer drum 18 and 
conveyor 20. The jackets so conveyed may form a shingled line and be 
conveyed directly to means for compensating and stacking. In order to 
enable the operator to deactivate the deflector mechanism 30, a solenoid 
(not shown) is provided which, when actuated, locks the cam follower 48 in 
the non-interrupt position. The solenoid is preferably actuated by a 
manual switch. A microswitch (not shown) is placed in series with the 
manual switch and solenoid so that the solenoid will retract only when 
there is a gap at the press stream. To this end, the microswitch is 
positioned adjacent the periphery of folding cylinder 12 so that it will 
close when contacted by a cam lobe (not shown) only at times when there is 
no jacket in the area of deflector blades 52. 
Referring now to FIGS. 1A and 1B, there is illustrated a tandem inserting 
machine 80 which is located remote from the printing press and which 
includes an insert feeding station 82, a compensating station 90 and a 
stacking station 100. Tandem inserting machine 80 receives spaced 
newspaper jackets 56 from conveyor 20 and auxiliary conveyor 32. As 
illustrated in FIG. 1A, the jackets 56 from conveyor 20 are deposited 
directly onto inserting line no. 1 with the jacket fold line 106 disposed 
toward the center of inserting machine 80. Jackets 56 conveyed between 
belts 62 and 70 of conveyor 32 are deposited on tandem inserting machine 
80 on the opposite side from conveyor 20. In the illustrated embodiment, 
belts 62, 70 make a loop as indicated by reference numeral 110 so that the 
fold line 106 is disposed at the center of inserting machine 80 when the 
jacket is deposited thereon. Thus, inserting machine 80 receives newspaper 
jackets 56 from opposite sides with their fold lines 106 disposed toward 
the center of machine 80 and with their open sides 108 disposed outwardly 
for engagement with the insert feeders in the manner described below. 
In the preferred embodiment, inserting machine 80 is driven by mechanical 
linkage (not shown) directly connected to printing press 10 so that the 
printing press, conveyors 20 and 32, deflect mechanism 30 and machine 80 
may be synchronously operated by a common drive. As jackets 56 are 
deposited onto inserting machine 80, the side-open edge of the jackets are 
positively engaged by timing spacing members 112 which are uniformly 
spaced on drive chain 113. To this end, the jackets 56 are deposited at 
some predetermined distance, for example 2-3 inches, in front of the next 
successive timing spacing member 112 and the spacing member is allowed to 
catch up with the side-open edge of the jacket 56 in order to positively 
direct it along inserting machine 80. 
A pair of insert feeder heads 120 and 122 are positioned immediately 
downstream from the point where jackets 56 are deposited on inserting 
machine 80. Before jacket 56 enters insert feeding station 82 the upper 
leaf of jacket 56 is opened by a conventional sword or pneumatic system 
(not shown) to allow an insert to be inserted into the jacket 56 so 
opened. It should be pointed out that the jackets are already 
"individualized" by virtue of their being conveyed at spaced intervals to 
inserting machine 80. Hence, the insert feeding line requires only the 
individualization of the inserts and not the individualization of the 
jackets. As pointed out above in the discussion of the prior art, 
conventional complete jacket feeder assemblies must individualize jackets 
from the bottom of a stack. In the preferred embodiment, the tandem 
inserting machine only requires insert feeder heads 120, 122 which may be 
model no. 227-E newspaper insert feeder heads manufactured by 
Muller-Martin Corporation of 40 Rabro Drive, Hauptauge, New York 11787. 
Other suitable insert feeding mechanisms may be utilized. 
Inserting machine 80 conveys the jackets plus inserts (hereinafter referred 
to as the "finished product") to compensating station 90 where the tandem 
finished products are merged into one line to form a compensated stack of 
two finished products. As illustrated in FIG. 1B, the path of jacket 56A 
is diverted so that the fold line of this jacket passes above the fold 
line of jacket 56B thus forming a compensated stack of two finished 
products. The merging of jacket 56A above jacket 56B is accomplished by 
raising the conveyor of jacket 56A so that its fold line is slightly 
higher than the fold line of jacket 56B. Then a siderail or equivalent 
deflector bar 95 urges jacket 56A over jacket 56B to form a compensated 
stack 56C of two finished products. 
The series of compensated stacks of two finished products is conveyed from 
the compensating station 90 to stacking station 100. Referring to FIGS. 2 
and 3, stacking station 100 is shown as including two on-line bins 142, 
144. This on-line double stacking bin arrangement is adapted to receive 
the single line delivery of compensated stacks of two finished products 
and to deliver them to a rollertop conveyor 150 in compensated bundles of 
a predetermined number. In operation, the compensated stacks from 
inserting machine 80 are first deposited into bin 142. In order to direct 
the stacks into bin 142 a deflector bar 151 is raised to the position 
shown in dashed lines in FIG. 2. When a complete bundle has been formed in 
bin 142, deflector bar 151 is lowered to the position shown in solid lines 
so that the finished products may be conveyed by a short conveyor 158 to 
the second bin 144. Bar 159 assists in guiding the finished products into 
bin 144. While bin 144 is receiving a flow of newspapers from conveyor 80, 
the stack in bin 142 is moved by a push arm 152 and its associated push 
face 153 to the surface of rollertop conveyor 150 (See FIG. 1B). In this 
manner bins 142 and 144 alternate to handle the continuous flow of 
compensated stacks of finished products from conveyor 80. Push arm 156 and 
push face 157 served to move the stack in bin 144 onto rollertop conveyor 
150 at the appropriate time. 
The bundle-size stacks on rollertop conveyor 150 are conveyed downstream to 
a tying station and a loading dock (not shown). 
OPERATION OF PREFERRED EMBODIMENT 
In operation, the illustrated apparatus provides a fully synchronized 
system for receiving newspaper jackets from a conventional rotary printing 
press, conveying said jackets on multiple conveyors, preferably in a 
spaced-apart manner, depositing said jackets on the inserting lines of a 
tandem inserting machine, feeding inserts into opposed jackets on said 
tandem inserting machine, merging the finished products on said tandem 
inserting machine into individual stacks of two compensated finished 
products, stacking said compensated stacks of two at a dual-bin stacking 
station and conveying the bundlesize stacks on a roller top conveyor to 
the tying operation and loading dock. 
In more detail, the operation is as follows: first the folded jackets are 
intercepted at the press folder before entering the shingling mechanism of 
said folder and are alternately diverted along multiple rather than single 
paths. That is, every other one of the jackets is received by the 
conventional press drum conveying mechanism 20 and the alternate jackets 
are received by an auxiliary conveying mechanism 32. The transport rates 
of both conveyors are the same and are preferably selected so that the 
jackets are conveyed away from the printing press in a nonoverlapping or 
non-shingled manner. The deflector mechanism utilized for diverting 
alternate newspapers is mechanically and/or electrically linked to the 
printing press to assure reliable synchronization. Likewise, the auxiliary 
conveyor is linked to the first conveyor or some component of the printing 
press to assure synchronization of the conveying mechanisms. 
The jackets on both conveyors are transferred to a remote location where 
they are deposited on a tandem inserting machine in an opposed 
relationship with their fold lines facing. The double line of jackets are 
transported to insert feeding stations where insert feeder heads feed the 
appropriate inserts into the jackets. Next the finished products (each 
comprising a jacket plus a selected number of inserts) are merged to form 
compensated stacks (i.e. stacks with folds opposing) of two finished 
products each. The compensated stacks are conveyed in a single line to one 
bin of the double bin stacking station which, as explained above, serves 
to accumulate stacks into a bundle of a predetermined size. Each bundle is 
laterally displaced to a roller top conveyor for transport to a tying 
station and a loading dock. 
ALTERNATIVE EMBODIMENTS 
Referring to FIG. 4, there is illustrated a schematic representation of an 
alternative embodiment of the present invention. According to this 
embodiment, the multiple conveyors 20', 32' exiting the printing press 10' 
convey the spaced jackets directly to a carousel-type insert feeder 170, 
for example a carousel insert feeder as manufactured by Sheridan 
Corporation. In this embodiment, the carousel comprises a rotating 
mechanism having a plurality of vertical slots 172 adapted to receive 
newpaper jackets by gravity feed. The carousel speed is mechanically 
and/or electrically linked to the press speed and the speed of the 
multiple conveyors so that a jacket may be fed into each successive or 
alternate slots 172 of the carousel. The jackets are then fed inserts in 
the manner known in the art. 
According to this alternative embodiment, alternate jackets are diverted at 
the press to provide multiple streams of spaced-apart jackets suitable for 
delivery to the carousel. Also it can be seen that synchronization between 
the conveyors and the carousel is critical. 
FIG. 5 illustrates a second alternative embodiment which may be used in 
association with a typical jaw type folder 200 found on some rotary 
printing presses. According to prior art practices, folder 200 operates to 
fold the jackets and deposit the jackets in a shingled fashion on a 
typical conveyor mechanism 205. In accordance with the present invention, 
jackets 56 are deflected from their normal path by a fixed deflector 212 
of the type utilized in quarter folding techniques which is located 
proximate drum 210. Deflector 212 serves to deflect jacket 56 to a short 
conveyor 215 also of the type used in quarter folding. At the end of 
conveyor 215 is located an oscillating diverter 230 which is mechanically 
and/or electrically linked to the press and diverts alternate jackets onto 
conveyors 220 and 232. Conveyors 220 and 232 transport the jackets to 
inserting line nos. 1 and 2 in the manner discussed above in connection 
with FIGS. 1, 1A and 1B. 
FIG. 6 illustrates an alternative embodiment of the inserting machine 
wherein the jackets are fed to the inserting lines nos. 1 and 2 by means 
of a pair of jacket feeders 300, 301. This embodiment differs from that 
illustrated in FIG. 1A in that the jacket feed is not synchronously driven 
by the press. Rather, jackets are brought to the feeders 300, 301 in 
bundles and then individualized and fed to the inserting lines by means of 
feeders 300, 301. This alternative embodiment retains the advantages 
associated with the insert feeding, compensating and stacking functions 
performed at stations 82, 90 and 100 without requiring a direct, 
synchronous press drive. 
Although the invention has been illustrated in conjunction with the feeding 
of inserts into newspaper jackets produced on a rotary printing press, the 
invention has application to the compilation of other types of printed 
matter. For example, magazines printed on a rotary press may be provided 
with inserts in accordance with the present invention. Also signatures of 
books may be conveyed from the press in the illustrated fashion in 
accordance with the present invention and then gathered to form a book in 
a manner analagous to insert feeding. 
The present invention also has utility in the compilation of a very large 
amount of printed matter, for example the Sunday edition of a newspaper. 
In this application parallel rotary printing presses with a common drive 
may each run a portion of the pages (for example, 1/2 each) which will 
comprise the Sunday edition. The jackets from one press may exit the press 
in a plurality of spaced-apart streams in accordance with the present 
invention. The jackets printed on the parallel press may be conveyed from 
the parallel press to an insert feeding station for insertion into the 
first jackets. This approach to the assembly of large newspapers 
recognizes that there is a practical limit to the size of a newspaper 
which may be printed on a conventional rotary printing press. 
Another application of the present invention is in the assembly of 
newspapers of relatively low circulation, for example, 10,000 copies. In 
such situations a relatively small rotary printing press may be used at 
high speed to make up portions of the newspaper. The portions are then 
assembled into a finished product at the inserting machine in accordance 
with the present invention. This system will enable a small newspaper to 
operate with fewer press units. The insert feeder heads utilized with this 
application of the present invention are much less costly than an 
additional press unit. 
Although most rotary printing presses have sufficient power to drive the 
deflecting mechanism, conveyors and inserting machines which are 
synchronously driven off the press, a power boost may be provided without 
losing the advantages of common drive and synchronization. 
While not illustrated, it is contemplated that more than two conveyors may 
be utilized to transport jackets from the printing press. In this regard, 
the deflector mechanism may be designed to divert jackets to more than two 
paths. Regardless of the number of paths (utilized with an equal number of 
conveyors), it is preferable that single successive jackets be directed to 
each path in succession. For example, if there are four paths, four 
conveyors and a deflector designed to deliver jackets to each of said 
paths, it is preferable to have one jacket delivered to each path in 
succession. In this way the conveyors may be operated at equal speeds and 
the jackets will be evenly spaced thereon in a non-shingled manner. 
Designs of deflectors for diverting the stream of jackets to more than two 
paths are not illustrated herein, but are believed to be within the 
capabilities of one skilled in the art. 
It should be noted that the present invention may be practiced without 
utilizing a flyer drum. The flyer drum was retained in the preferred 
embodiment so that when the deflector mechanism is deactivated the 
printing press may operate through the flyer drum to form a shingled 
conveyance of jackets in the manner known in the art. However, where such 
operation is not desired, the flyer drum may be replaced by other conveyor 
means, for example means operated as auxiliary conveyor 32. Also, it is 
within the scope of the invention to use multiple flyer drums to transfer 
jackets to appropriate conveyor means. 
As used herein, the term "jacket" is deemed to include any printed matter 
into which an insert or inserts may be fed. Although not illustrated, the 
insert feeding station may include means for inserting a plurality of 
inserts into each jacket.
