Background of the Invention
[0001] The present invention relates to an apparatus for use in forming groups of folded
signatures with personalized information printed on one or more of the signatures.
[0002] A known apparatus for forming groups of signatures with personalized information
printed on one or more of the signatures is disclosed in U.S. Patent No. 4,395,031
issued July 16, 1983 titled "Apparatus for Printing Books of Signatures and Method
for Same". In this known apparatus, groups of signatures are formed on a saddle type
conveyor. An ink jet printer is utilized to print personalized information on the
signatures.
[0003] When this known apparatus is used to print personalized information on a signature,
the lines of characters setting forth the personalized information extend parallel
to the fold in the signature. Thus, as the signature is being moved by the saddle
type conveyor in a direction parallel to the fold in the signature, each printer head
of a plurality of printer heads prints a line of characters which extends parallel
to the path of movement of the signature. However, preprinted material on the signature
conventionally extends perpendicular to the fold. Therefore, the personalized information
which is printed on the signature is disposed in an orientation which is different
than the other material printed on the signature.
Summary of the Invention
[0004] The present invention provides an apparatus which is operable to form groups of signatures
and to print personalized information, on one or more of the signatures. The personalized
information is printed in one or more lines of characters extending perpendicular
to a fold in the signature.
[0005] The apparatus includes a longitudinally extending main conveyor, which may be of
the well known saddle type, having a plurality of receiving locations. A plurality
of signature feed assemblies are disposed in an array along the main conveyor to sequentially
feed preprinted folded signatures onto the main conveyor at each of the receiving
locations. At least one of the signature feed assemblies includes a printer which
prints at least one line of characters on one of the signatures. The line of characters
extends perpendicular to the fold in the signature.
[0006] The signature feed assembly in which the printing occurs, includes a hopper for holding
preprinted folded signatures. A transfer assembly sequentially transfers the signatures
to the main conveyor. A secondary conveyor moves the signatures from the hopper to
the transfer assembly. A printer, which may be of the ink jet type, is disposed adjacent
to the secondary conveyor and prints at least one line of characters on each of the
signatures in turn. The printed line of characters extends perpendicular to the fold
in the signature.
[0007] Accordingly, it is an object of this invention is to provide a new and improved apparatus
in which groups of signatures are formed on a main conveyor and in which information
is printed on the signatures in one one or more lines of characters extending perpendicular
to a fold in the signature.
[0008] Another object of this invention is to provide a new and improved apparatus for use
in forming groups of signatures wherein the signatures are moved from a supply hopper
to an assembly which sequentially transfers the signatures to a main conveyor and
wherein a line of characters is printed on each of the signatures in turn as the signature
is moved from the supply hopper to the transfer assembly.

DESCRIPTION OF ONE SPECIFIC PREFERRED EMBODIMENT OF THE INVENTION
[0010] A group 10 of signatures having personalized information 12 printed on an outer signature
13 in a known manner is illustrated in Fig. 1. The signature 13 includes a pair of
opposite major sides 14 and 16 which are separated by a fold 18. The personalized
information 12 includes a plurality of lines 22, 24, and 26 of characters. Lines 22,
24, and 26 of characters extend parallel to the fold 18. However, preprinted material,
indicated schematically at 30, on the signature 13 includes lines of characters which
extend perpendicular to the fold 18. Thus, the personalized information 12 and the
preprinted material 30 extend transversely relatively to each other rather being oriented
in the same direction.
[0011] The outer signature 34 (Fig. 2) of a second group 35 of signatures also has a pair
of major sides 36 and 38 which are interconnected at a fold 40. Personalized information
42 is printed on the major side 38 of the signature 34. The personalized information
42 includes a plurality of lines 44, 46, and 48 of characters.
[0012] In accordance with a feature of the present invention, the lines 44, 46, and 48 of
characters on the signature 34 extend perpendicular to the fold 40. Preprinted material,
indicated schematically at 52 in Fig. 2, also contains lines of characters which extend
perpendicular to the fold 40. Thus, both the preprinted material 52 and the personalized
information 42 on the major side 38 of the signature 34 extend perpendicular to the
fold 40 and have the same orientation relative to the signature. Since the material
52 and personalized information 42 are both printed in the same orientation on the
major side 38 of the signature 34, both areas of material can be readily read.
[0013] Although the personalized information is printed on only the outer signature 34 of
the group 35 of signatures, personalized information could be printed on other signatures
of the group of signatures. This personalized information would also be printed in
one or more lines of characters extending perpendicular to a fold in the signature.
[0014] A collator apparatus 60 constructed in accordance with the present invention is illustrated
schematically in Fig. 3. The collator forms groups 35 of preprinted folded signatures
with personalized information printed on at least one signature 34 of the group of
signatures, as illustrated in Fig. 2. Thus, the personalized information is printed
on the signature 34 in lines 44, 46, and 48 of characters which extend perpendicular
to a fold 40 in the signature.
[0015] The apparatus 60 includes a longitudinally extending main conveyor assembly 62. The
main conveyor assembly 62 is of the well known saddle type. The conveyor assembly
62 includes a plurality of pusher fingers or lugs 64 which are connected to a conveyor
chain and cooperate with each other to form signature receiving locations 66.
[0016] The signature receiving locations 66 are moved along a linear path in the direction
of the arrow 68, by the main conveyor 62. Signature feeder assemblies 72, 74, 76 and
78 are disposed in a linear array along the main conveyor 62. The signature feed assemblies
72-78 sequentially feed preprinted folded signatures to each of the receiving locations
66 on the main conveyor 62 to sequentially form groups 35 of signatures.
[0017] As each of the signature receiving locations 66 moves past each of the signature
feed assemblies 72-78 in turn, a group 35 of signatures is formed at the receiving
location. The pusher finger 64 engages a trailing edge portion of the group 35 of
signatures and moves the signatures in the direction of the arrow 68.
[0018] Since the main conveyor 62 is of the well known saddle type, the groups 35 of signatures
hang downwardly from the main conveyor 62. The opposite major sides of each of the
signatures extends downwardly on opposite sides of the saddle conveyor 62. The fold
which separates the major sides of each signature is disposed along the center line
of the saddle conveyor 62. The saddle conveyor 62 has opposite side surfaces which
slope downwardly and outwardly from a peak portion of a conveyor. These side surfaces
engage inner side surfaces on the lowermost signature in a group 35 of signatures
to support the group of signatures in a known manner.
[0019] The signature feed assemblies 72, 74, and 76 each include a hopper 82 which holds
different preprinted and folded signatures. A signature transfer assembly 84 is provided
in each of the signature feed assemblies 72, 74, and 76 to sequentially feed signatures
from a hopper 82 to receiving locations 66 on the main conveyor 62 as the receiving
locations sequentially move past the transfer assemblies 84. The signature feed assemblies
72, 74, and 76 all have the same construction. However, the signature feed assembly
78 differs from the signature feed assemblies 72, 74, and 76 in that the signature
feed assembly 78 includes a secondary conveyor 86 which sequentially moves signatures
34 from a hopper 82 to a transfer assembly 84.
[0020] A printer assembly 88 in the signature feed assembly 78 (Fig. 4) prints personalized
information on each of the preprinted and folded signatures 34 as it is moved from
the hopper 82 to the transfer assembly 84 by the secondary conveyor 86. The personalized
information is printed on each of the signatures 34 in lines 44, 46, and 48 of characters
which extend perpendicular to the fold 40, in the manner illustrated in Fig. 2.
[0021] The preprinted and folded signatures 34 are moved from the hopper 82 to the secondary
conveyor 86 with the folds 40 leading. The secondary conveyor 86 moves the signatures
34 toward the main conveyor 62 along a path which extends perpendicular to the longitudinal
central axis of the main conveyor 62 with the major sides 38 horizontal and facing
upwardly and the with the major sides 36 horizontal and facing downwardly. As each
signature 34 is moved through the printer assembly 88 by the secondary conveyor 86,
personalized information is printed on the signature. The personalized information
is printed in lines 44, 46, and 48 of characters which extend parallel to the path
of movement of the signature and perpendicular to the path of movement of the main
conveyor 62. The personalized information may be printed either directly on the signature
or on a label disposed on the signature.
[0022] The signatures 34 with the personalized information printed on the major sides 38,
are sequentially transferred to the main conveyor 62 by the transfer assembly 84.
When the signatures 34 are transferred to the main conveyor assembly 32, the lines
44, 46, and 48 of characters printed by the printer assembly 88 extend perpendicular
to the longitudinal central axis of the main conveyor 62 and the path of movement
of the signatures by the main conveyor.
[0023] The signature feed assembly 78 includes a hopper 82 (Fig. 4) which holds a supply
of preprinted and folded signatures 34. The signatures are held in the hopper 82 with
the folded edges 40 of the signatures downwardly and with the major sides 38 facing
toward the right (as viewed in Fig. 4). A rotary separator drum 92 disposed adjacent
to the hopper 82 sequentially grips the signatures and removes them from the hopper.
The drum 92 releases the signatures at the receiving locations 94 disposed on the
secondary conveyor 86 between pusher fingers or lugs 96. The pusher fingers 96 engage
the trailing edges of the signatures 34 to sequentially move them through the printer
assembly 88.
[0024] The printer assembly 88 is of the known ink jet type. The printer assembly 88 includes
a nozzle for each line of characters to be printed on the major side of a signature.
Charged droplets from the nozzles pass between deflection plates and are deflected
to form characters. The printer assembly 88 includes an upper set of nozzles 102 which
can print lines of characters on the upwardly facing major side 38 of each of the
signatures 34 in turn. A lower set of nozzles 104 is also provided to print lines
of characters on the downwardly facing major side 36 of each of the signatures in
turn. Either or both sets of nozzles 102 and 104 can be used to print on each of the
signatures as they move through the printer 88.
[0025] After the signatures 34 pass through the printer assembly 88, they move to the transfer
assembly 84. In transfer assembly 84, grippers on a rotary feed drum 108 grip each
of the signatures 34 in turn. The feed drum 88 moves each signature 34 in turn part
way around the drum and then releases the signature. The transfer cylinder 110 engages
the open edges of the signature and carries it to an opener cylinder 112. The signature
34 is opened by cooperation between the transfer and opener cylinders 110 and 112
and is dropped downwardly onto the main conveyor assembly 62. The transfer assembly
84 may have many different known constructions, such as those illustrated in U.S.
Patent Nos. 2,251,943; 2,855,195; 3,692,300; 3,809,384; and 3,692,300.
[0026] The signature 34 is placed on main saddle conveyor 62 with the fold 40 extending
parallel to the path of movement of the main conveyor and with the lines 44, 46, and
48 of characters printed on the signature by the printer assembly 88 extending perpendicular
to the longitudinal axis of the main conveyor. The main conveyor 62 moves the group
35 of signatures, including the signatures 34, to additional stations where further
operations are performed on the signatures. For example, the signatures may be moved
to a stitcher assembly in which the group 35 of signatures is stapled along the folds
40.
[0027] In view of the foregoing description, is apparent that the present invention provides
an apparatus 60 which is operable to form groups 35 of signatures and to print personalized
information, on one or more of the signatures. The personalized information is printed
in one or more lines of characters 44, 46, and 48 extending perpendicular to a fold
40 in the signature 34.
[0028] The apparatus includes a longitudinally extending main conveyor 62, which may be
of the well known saddle type, having a plurality of receiving locations. A plurality
of signature feed assemblies 72, 74, 76, and 78 are disposed in an array along the
main conveyor 62 to sequentially feed preprinted folded signatures onto the main conveyor
at each of the receiving locations 66. At least one of the signature feed assemblies
includes a printer 88 which prints at least one line of characters on one of the signatures
34. The line of characters extends perpendicular to the fold 40 in the signature 34.
[0029] The signature feed assembly 78 in which the printing occurs, includes a hopper 82
for holding preprinted folded signatures 34. A transfer assembly 84 sequentially transfers
the signatures 34 to the main conveyor. A secondary conveyor 86 moves the signatures
34 from the hopper 82 to the transfer assembly 84. A printer 88, which may be of the
ink jet type, is disposed adjacent to the secondary conveyor 86 and prints at least
one line of characters on each of the signatures 34 in turn. The printed line of characters
extends perpendicular to the fold 40 in the signature 34.
[0030] Although the printer 88 has been described herein as being operable to print on the
outermost signature 34 of the group 35 of signatures, additional printers could be
provided in association with the signature feed assemblies 72, 74, and/or 76. These
printers would be operable to print personalized information on signatures disposed
within the group 35 of signatures. The personalized information printed on the signatures
within the group 35 of signatures would also extend perpendicular to the folds in
the signatures.
