PROVISIONAL SPECIFICATION.
Attachments to Rotary Printing Machines Serving to Count and to
Sew Copies of Works Printed on such Machines, the Sewing
Attachments being also Capable of Use Independently of such
Printing Machines.
I, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-
In Fig. 1 the printed and folded copy of the work descends between the cords or
or circular eccentric
tapes 100 101 is a flyer or pusher actuated by a cam
mounted on the shaft 102, by means of a set of levers. With the two wheels 103
and 1031 engages a chain formed of parts 104 connected together by studs or
pins 105; the wheel 103 is mounted on a shaft also carrying a wheel 106 which
revolves through a certain angle for a given number of printed and delivered sheets.
To increase the stability of the apparatus I place a roller 107 on each end of
the studs 105, such rollers bearing upon ways 108 fixed to the frame of the machine.
The flyer or pusher 101 is cut away so as to permit the parts 104 to pass. The
sheet arriving at 100 abuts against table 109 and the horizontal portion of part 104;
it is pushed by flyer 101 against the vertical portion of the part 104 then in front
of such flyer. When the number of sheets which are to be contained within two
vertical positions is attained, the wheel 106 revolves under the action of wheel 110,
and the part 104" is brought to the position of the part 104b; the packet formed
between these two partitions advancing between two movements of the flyer
or pusher, is brought within easy reach of the workman who has to remove the
packets.
By referring to Fig. 1 it will be seen that a certain number of such packets may
be in position for removal in advance of the point at which they are to be removed,
and that it is not necessary to remove same as they are formed.
In Fig. 3 I have shown another arrangement producing the same result, but in
this case the parts 104 are replaced by a sheet or band 111 mounted on two
drums 112 and 113, the latter being driven from the printing machine. On the
band partitions 114 replace the parts 104; counter parts 115 serve to arrest
same and at same time form the elements of a kind of chain gearing with the
drums 112 and 113, thus ensuring the regular displacement of the band.
In the apparatus shown in Figs. 4 and 5 the sheets descending between the cords
or tapes 115, pass between the partitions 116 and abut against the drum 117; at
this moment two flyers 118 and 118' which are actuated by cams or eccentrics
mounted on shaft 120 through connecting rods 119, strike the sheet and force same
against the plate 121; the drum revolves under the action of wheel 122, which,
like wheel 106, describes an arc of a circle for a given number of sheets received,
and the partition 121' takes the place of 121, then the partition 121", and so on,
so that between two partitions 121 there is a packet containing the desired number
of sheets.
Figs. 6 and 7 show another form of apparatus in which the sheet just printed
and folded is delivered at 123 and in a horizontal direction; at the moment
it abuts against the partition 125, the flyer or pusher 124 comes in contact there-
with and forcing same down causes it to leave the cords or tapes 126 which
have carried it, and it falls on to a cord or belt 127 over which it bends or folds
as shown in Fig. 7. This cord 127 passes over two pulleys 128 and 128', the
one 128 of which is mounted on a shaft carrying a wheel similar to wheel 106
shown in Fig. 1, and which revolving through a certain angle for a given number

page_text: of sheets delivered, will carry forward the packet formed by these sheets; the
result of this movement is that the different packets will advance along the
cord 127, a distance, depending upon the travel of such cord at each displacement,
separating such packets. I may employ two partitions 129 serving to prevent the
fold becoming too marked or pronounced.
In Figs. 8 and 9 the apparatus shown is composed of three drums 130 formed of
blades, and having the form of a regular prism one end of each of the sides of
which is prolonged; the sheets arriving at 131 are pushed by the flyer or pusher
on to the partition formed by one of the sides of the prism; when the desired
number of sheets has been received, the prism revolves under the action of a
wheel 132 so as to present another of its sides as a stop to the sheets to be
received. So that the removal of the packet of sheets may be effected under
favorable conditions, it will be seen in the drawings that the prolonged sides of the
prism, as 133, pass between the plates 134, which are prolongations of the table
on to which the sheet falls on its descent, and which support the end of the packet
until same is removed.
The packets thus removed are then deposited upon two bands 133' which pass
over pulleys actuated by the machine so as to travel continuously and at such a
speed as to remove each packet, so that the prolonged sides of the prism will not
come in contact therewith on their next movement.
In Fig. 10 the sheets descending at 135 are forced by the flyer or pusher against
the fixed partition 136, in front of which is a cylinder 137 carrying a certain
number of grippers; when the flyer carries forward the last sheet of a packet, the
grippers 138 of the cylinder close, at the moment that the flyer moves back, and
the cylinder 137 then begins to revolve carrying forward the packet; I may
cause this cylinder to revolve through such an arc that the packet is entirely
removed when the flyer or pusher again returns to force a fresh sheet against the
partition 136, or I may impart a succession of movements of small extent thereto
at each return movement of the flyer, so as to remove the packet without
any sudden
shock, and in such a way that a new set of grippers is presented to seize the next
packet of sheets formed while the preceding one is being removed.
I may obtain this result by means of wheels such as 139 and 140 which are
suitably proportioned.
Beneath the cylinder an endless band or belt 141 to which a continuous move-
ment is imparted receives the packets and carries them forward out of the machine
separated from each other by a distance determined by the speed at which such
belt, which is actuated by two drums 142, 143, travels between the reception of
two packets.
I may also deposit the sheets, when they leave the cylinder, on to a movable
table having a lateral to and fro movement to separate the packets. I may further
employ a flyer to remove the sheets from the cylinder and deposit then on the
belt or on the table.
In Figs. 11 and 12 the packet of sheets applied as before by the flyer to the
fixed stop or abutment 144 is seized by grippers 145 and carried forward by a belt
or band 146; this belt or band is in two parts and passes over drums 147 and 147',
the one 147 of which is mounted on a shaft carrying a wheel 148 which operates in
the same manner as the wheel 139 of Fig. 10.
In the middle of the drums toothed wheels serving to carry forward the chains
on which the grippers are mounted are arranged; I may employ two chains and
several sets of grippers. The operation is the same as that of the cylinder in
Fig. 10, that is to say, the packets seized may be carried forward either little by
little, by successive advances between two movements of the flyer, or in a single
movement by a travel equal to their length, the chain then remaining stationary
until the formation of a new packet.
In Figs. 13 and 14 the apparatus shown has for its object to separate the packets
from each other in the box or tray to which they are delivered.
The flyer or pusher 149 forces the sheets in succession into the passage formed

page_text: by the walls 150, 151, and the table 152¹; a vertical shaft 152 carries a wheel 154
actuated by the machine, and itself actuating a shaft 153 by means of a chain
passing over a wheel 155 and a wheel 155'; at their upper ends the two shafts 152
and 153 carry drums over which passes a belt carrying blades such as 156; at the
moment when the last sheet constituting a packet is pushed forward by the
flyer 149, a movement of the system formed by the two shafts and the belt causes
the latter to advance so that a blade 156 is interposed between the packet received
and that to be next formed, and so that there is thus a packet of the number of
sheets desired and fixed in advance between two blades 156.
A further improvement I have made in rotary printing machines consists in
applying to such machines suitable apparatus for uniting and sewing together a
given number of superposed sheets or the different parts of a sheet which bas
réceived a certain number of folds.
In Figs. 15, 16 and 17, 1 represents the whole of the sheets to be united, same
being composed of single sheets or of sheets already folded and superposed or of a
single sheet which has received a certain number of folds.
This packet of sheets 1 coming from the folding or accumulating cylinders passes
over a roller 2 in a groove in which a disc 3 forces the paper so as to form a fold or
crease in the manner described in the Specification of my prior Patent No. 2631
dated 14th February 1889. The packet 1 then comes in contact with the stop 4,
at which moment the cords which carry it along separate; I may obtained this
movement in different ways, such as by causing the tube 5 mounted on lever 6
to rise under the action of a cam 7, as I have shown, or in any other suitable
manner. -
While the packet stops the two parts 8 and 9 of the sewing mechanism approach
each other and the sewing is effected. For the sewing I employ the usual
apparatus operating either with a flexible thread, such as cotton or other thread,
or, as I have shown, with a metallic wire. 10 is the reel of wire which unrolls
under the action of drawing rolls 11 and 12; the cutting of the thread and its
insertion in the paper is effected in the ordinary manner.
When the sewing is accomplished the stop 4 is lowered under the action of a
cam mounted on the shaft 13, the tapes are brought together again and the packet
is carried forward and brought in contact with the stop 14; a blade 15 causes it to
engage folded between the rollers 16, whence it is conducted to the delivery.
In Fig. 18 I have shown the same part of the machine with the difference that
the fold or crease has to be made above instead of below, the sewing mechanism,
the folding blade and the rollers being arranged inversely to the arrangement in
Fig. 15.
I may employ several sewing mechanisms to each of which a packet of sheets
will be conveyed; for this purpose a part such as 17 (Fig. 15) for directing the
packets in different directions is only necessary.
may also employ several sewing mechanisms arranged for acting upon a single
packet, and I may further deliver the packet after sewing without folding same.
I may further apply the arrangements above described and also those which are
hereinafter described, to folding machines which are independent of printing
machines.
In Fig. 19 I have shown another method of sewing and folding.
Cylinder 18 is an accumulating cylinder; the sheets accumulated by it are by
the flyers 19 deposited upon table 20, in which one part 21 of the sewing machine
is arranged; the thread is supplied from reel 22. When the sheets have been
deposited by the flyer 19 on table 20, the part 23 is lowered and the sewing
effected. At the moment the lever 23 withdraws, the packet seized by the
grippers 24 of cylinder 25 is carried forward; it may be folded between the
cylinders 25 and 26 by means of folding blades 27 and 28, or it may be delivered
without folding. I may further mount the sewing mechanism on cylinders.
In Figs. 20 and 21, 29 is a cylinder upon which a certain number of sheets are
superposed; when the desired number is attained, the grippers 35 of cylinder 30

page_text: seize the packet, and the sewing mechanism 31 and 32 being brought into operation
under the action of the cams 33 and 34, the sewn packet is carried forward, then
released by cylinder 30 and proceeds either to the delivery or to other folding
cylinders; I may if desired make a fold on the cylinders 29 and 30. The sheets
may be delivered to cylinder 29 already superposed or they may be accumulated
thereon without the cylinder requiring grippers for that purpose.
I may effect the sewing on cylinders in different operations, Fig. 22 illustrating
an arrangement I employ for this purpose. The sheets are carried forward ou
cylinder 41, and first come in contact with the disc 35 carrying needles 36 which
pierce the holes, then with cylinder 37 which carries the apparatus forming the
hooks in passing in front of this cylinder the packet of sheets receives this hook
and when the hook engaged in the paper passes over roller 38 the apparatus 39
which compresses the hook enters into operation; the sheets are then released
at 40.

Attachments to Rotary Printing Machines Serving to Count and to
Sew Copies of Works Printed on such Machines, the Sewing
Attachments being also Capable of Use Independently of such
Printing Machines.
J, JULES MICHAUD, of 96 Rue d'Assas, Paris, France, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the drawings accompanying the Provisional
Specification as well as to the three additional sheets accompanying the present
Specification:-
In Figs. 1 and 2 the printed and folded copy of the work descends between the
cords or tapes 100; 101 is a flyer or pusher actuated by a cam or circular eccentric
mounted on the shaft 102, by means of a set of levers. With the two wheels 103
and 103 engages a chain formed of parts 104 connected together by studs or
pins 105; the wheel 103 is mounted on a shaft also carrying a wheel 106 which
revolves through a certain angle for a given number of printed and delivered
sheets.
To increase the stability of the apparatus I place a roller 107 on each end of
the studs 105, such rollers bearing upon ways 108 fixed to the frame of the
machine.
The flyer or pusher 101 is cut away so as to permit the parts 104 to pass.
The
sheet arriving at 100 abuts against table 109 and the horizontal portion of part 104
it is pushed by flyer 101 against the vertical portion of the part 104 then in front of
such flyer. When the number of sheets which are to be contained within two
vertical partitions is attained, the wheel 106 revolves under the action of wheel 110,
and the part 104" is brought to the position of the part 104°; the packet formed
between these two partitions advancing between two movements of the flyer or
pusher, is brought within easy reach of the workman who has to remove the
packets.
By referring to Fig. 1 it will be seen that a certain number of such packets
may be in position for removal in advance of the point at which they are to be
removed, and that it is not necessary to remove same as they are formed.
In Fig. 3 I have shown another arrangement producing the same result, but in
this case the parts 104 are replaced by a sheet or band 111 mounted on two
drums 112 and 113, the latter being driven from the printing machine. On the

page_text: band partitions 114 replace the parts 104; counter parts 115 serve to fix same and
at same time form the elements of a kind of chain gearing with the drums 112
and 113, thus ensuring the regular displacement of the band.
In the apparatus shown in Figs. 4 and 5 the sheets descending between the cords
or tapes 115, pass between the partitions 116 and abut against the drum 117; at
this moment two flyers 118 and 118¹ which are actuated by cams or eccentrics
mounted on shaft 120 through connecting rods 119, strike the sheet and force same
against the plate 121; the drum revolves under the action of wheel 122, which,
like wheel 106, describes an arc of a circle for a given number of sheets received,
and the partition 121' takes the place of 121, then the partition 121", and so on, so
that between two partitions 121 there is a packet containing the desired number of
sheets.
Figs. 6 and 7 show another form of apparatus in which the sheet. just printed
and folded is delivered at 123 and in a horizontal direction; at the moment it
abuts against the partition 125, the flyer or pusher 124 comes in contact therewith
and forcing same down causes it to leave the cords or tapes 126 which have carried
it, and it falls on to a cord or belt 127 over which it bends or folds as shown in
Fig. 7. This cord 127 passes over two pulleys 128 and 128', the one 128 of which
is mounted on a shaft carrying a wheel similar to wheel 106 shown in Fig. 1, and
which revolving through a certain angle for a given number of sheets delivered,
will carry forward the packet formed by these sheets; the result of this movement
is that the different packets will advance along the cord 127, a distance, depending
upon the travel of such cord at each displacement, separating such packets.
may employ two partitions 129 serving to prevent the fold becoming too marked
or pronounced.
I
In Figs. 8 and 9 the apparatus shown is composed of three drums 130 formed of
blades, and having the form of a regular prism one end of each of the sides of
which is prolonged; the sheets arriving at 131 are pushed by the flyer or pusher
on to the partition formed by one of the sides of the prism; when the desired
number of sheets has been received, the prism revolves under the action of a
wheel 132 so as to present another of its sides as a stop to the sheets to be
received. So that the removal of the packet of sheets may be effected under
favorable conditions, it will be seen in the drawings that the prolonged sides of the
prism, as 133, pass between the plates 134, which are prolongations of the table
on to which the sheet falls on its descent, and which support the end of the packet
until same is removed.
The packets thus removed are then deposited upon two bands 133¹ which pass
over pulleys actuated by the machine so as to travel continuously and at such a
speed as to remove each packet, so that the prolonged sides of the prism will not
come in contact therewith on their next movement.
In Fig. 10 the sheets descending at 135 are forced by the flyer or pusher against
the fixed partition 136, in front of which is a cylinder 137 carrying a certain
number of grippers; when the flyer carries forward the last sheet of a packet, the
grippers 138 of the cylinder close, at the moment that the flyer moves back, and
the cylinder 137 then begins to revolve carrying forward the packet; I may cause
this cylinder to revolve through such an arc that the packet is entirely removed
when the flyer or pusher again returns to force a fresh sheet against the
partition 136, or I may impart a succession of movements of small extent thereto
at each return movement of the flyer, so as to remove the packet without any
sudden shock, and in such a way that a new set of grippers is presented to seize
the next packet of sheets formed while the preceding one is being removed.
I may obtain this result by means of wheels such as 139 and 140 which are
suitably proportioned.
Beneath the cylinder an endless band or belt 141 to which a continuous move-
ment is imparted receives the packets and carries them forward out of the machine
separated from each other by a distance determined by the speed at which such

page_text: belt, which is actuated by two drums 142, 143, travels between the reception of
two packets.
I may also deposit the sheets, when they leave the cylinder, on to a movable
table having a lateral to and fro movement to separate the packets. I may further
employ a flyer to remove the sheets from the cylinder and deposit them on the belt
or on the table.
In Figs. 11 and 12 the packet of sheets applied as before by the flyer to the fixed
stop or abutment 144 is seized by grippers 145 and carried forward by a belt or
band 146; this belt or band is in two parts and passes over drums 147 and 1471, the
one 147 of which is mounted on a shaft carrying a wheel 148 which operates in the
same manner as the wheel 139 of Fig. 10.
In the middle of the drums toothed wheels serving to carry forward the chains on
which the grippers are mounted are arranged; I may employ two chains and
several sets of grippers. The operation is the same as that of the cylinder in
Fig. 10, that is to say, the packets seized may be carried forward either little by
little, by successive advances between two movements of the flyer, or in a single move-
ment by a travel equal to their length, the chain then remaining stationary until
the formation of a new packet.
In Figs. 13 and 14 the apparatus shown has for its object to separate the packets
from each other in the box or tray to which they are delivered.
The flyer or pusher 149 forces the sheets in succession into the passage formed by
the walls 150, 151, and the table 152¹; a vertical shaft 152 carries a wheel 154
actuated by the machine, and itself actuating a shaft 153 by means of a chain
passing over a wheel 155 and a wheel 155'; at their upper ends the two shafts 152
and 153 carry drums over which passes a belt carrying blades such as 156; at the
moment when the last sheet constituting a packet is pushed forward by the flyer 149,
a movement of the system formed by the two shafts and the belt causes the latter
to advance so that a blade 156 is interposed between the packet received and that
to be next formed, and so that there is thus a packet of the number of sheets
desired and fixed in advance between two blades 156.
A further improvement I have made in rotary printing machines consists in
applying to such machines suitable apparatus for uniting and sewing together a
given number of superposed sheets or the different parts of a sheet which has
received a certain number of folds.
In Figs. 15, 16 and 17, 1 represents the whole of the sheets to be united, same
being composed of single sheets or sheets already folded and superposed or of a
single sheet which has received a certain number of folds..
This packet of sheets 1 coming from the folding or accumulating cylinders passes
over a roller 2 in a groove in which a disc 3 forces the paper so as to form a fold or
crease in the manner described in the Specification of my prior Patent No. 2631
dated 14th February 1889. The packet I then comes in contact with the stop 4,
at which moment the cords which carry it along separate; I may obtain this
movement in different ways, such as by causing the tube 5 mounted on lever 6 to
rise under the action of a cam 7, as I have shown, or in any other suitable manner.
While the packet stops the two parts 8 and 9 of the sewing mechanism approach
each other and the sewing is effected. For the sewing 1 may employ the usual
apparatus operating either with a flexible thread, such as cotton or other
thread, or, as I have shown, with a metallic wire. 10 is the reel of wire which
unrolls under the action of drawing rolls 11 and 12; the cutting of the thread and
its insertion in the paper is effected in the ordinary manner.
When the sewing is accomplished the stop 4 is lowered under the action of a cam
mounted on the shaft 13, the tapes are brought together again and the packet is
carried forward and brought in contact with the stop 14; a blade 15 causes it to
engage folded between the rollers 16, whence it is conducted to the delivery.
In Fig. 18 I have shown the same part of the machine with the difference that
the fold or crease has to be made above instead of below, the sewing mechanism,

page_text: the folding blade and the rollers being arranged inversely to the arrangement in
Fig. 15.
I may employ several sewing mechanisms to each of which a packet of sheets
will be conveyed; for this purpose a part such as 17 (Fig. 15) for directing the
packets in different directions is only necessary.
I may also employ several sewing mechanisms arranged for acting upon a single
packet, and I may further deliver the packet after sewing without folding same.
I may further apply the arrangements above described and also those which are
hereinafter described, to folding machines which are independent of printing
machines.
In Fig. 19 I have shown another method of sewing and folding.
Cylinder 18 is an accumulating cylinder; the sheets accumulated by it are by
the flyers 19 deposited upon the table 20, in which one part 21 of the sewing
machine is arranged; the thread is supplied from reel 22. When the sheets have
been deposited by the flyer 19 on table 20, the part 23 is lowered and the
sewing effected. At the moment the lever 23 withdraws, the packet seized by
the grippers 24 of cylinder 25 is carried forward; it may be folded between the
cylinders 25 and 26 by means of folding blades 27 and 28, or it may be delivered
without folding. I may further mount the sewing mechanism on cylinders.
In Figs. 20 and 21, 29 is a cylinder upon which a certain number of sheets are
superposed; when the desired number is attained, the grippers 35 of cylinder 30
seize the packet, and the sewing mechanism 31 and 32 being brought into operation
under the action of the cams 33 and 34, the sewn packet is carried forward, then
released by cylinder 30 and proceeds either to the delivery or to other folding
cylinders; I may if desired make a fold on the cylinders 29 and 30. The sheets
may be delivered to cylinder 29 already superposed or they may be accumulated
thereon without the cylinder requiring grippers for that purpose.
I may effect the sewing on cylinders in different operations, Fig. 22 illustrating
an arrangement I employ for this purpose. The sheets are carried forward on
cylinder 41, and first come in contact with the disc 35 carrying needles 36 which
pierce the holes, then with cylinder 37 which carries the apparatus forming the
hook or staple; in passing in front of this cylinder the packet of sheets receives
this hook or staple, and when the hook or staple engaged in the paper passes over
roller 38 the apparatus 39 which compresses or clamps the hook or staple enters
into operation; the sheets are then released at 40.
The new Figs. 23, 23*, 24 and 25 show in detail a special sewing apparatus which
is only indicated in general outline in Figs. 20 and 21.
Figs. 23 and 23* show the apparatus complete on a reduced scale; the details
being shown full sized in Figs. 24 and 25.
45 is a cylinder to which a certain number of superposed sheets, which are to be
bound together, is delivered, such sheets being either delivered to the cylinder 45
by means of tapes, or seized by the grippers 46 of such cylinder.
In its rotation cylinder 45 carries with it the apparatus serving to form the hook
or staple, and to insert same in the paper; above such cylinder 45 a disc 47 carries
the apparatus for clamping such hook or staple, and thus completing the sewing.
I will first describe the apparatus for forming such hook or staple and inserting
it in the paper.
In the cylinder 45 is a reel 48 carrying the wire serving to make
the hook or staple; a wheel 49, the centre of which coincides with that of
cylinder 45, is fixed to the frame of the machine; the wheel 50 gears therewith,
and is mounted on a shaft 51 projecting into the cylinder. The shaft 51 at its other
end carries a mitre wheel 52. The wheel 52 drives a wheel 53 on which is fixed
the wire feed roller 54.
The feed of the wire is effected by the pressure of the roller 55 on roller 54.
The proportions of the different gear wheels 49, 50, 52, 53, are calculated so that
the roller 54 revolves once for each revolution of the cylinder 45, when only a
single disc such as 47 is in contact with such cylinder.

page_text: The roller 54 has a projecting part 56, and it is only on the contact of this
part with the roller 55 that the feed of the wire takes place. The length of the
part 56 corresponds to the length of wire necessary for forming the hook or
staple.
The wire fed from the reel 48 passes through a guide 57, then between the feed
rolls 55 and 54, and through a guide 58, and arrives at 59. A part 60 actuated by
a cam 61 effects the cutting of the wire, and by applying it against a stop 62 forms
the hook or staple. At this moment under the action of cam 63 the stop 62 moves
back, and at the same time acts on the part 65 which causes the hook or staple to
pass through the paper.
By causing the projection of the hook or staple to coincide with the arrival of
the counter part 68 on the disc 47, the hook or staple engages with such counter
part, and a blade 64 being lowered by the action of a cam 66, lays the two wings
of the hook or staple on the paper, which is then carried forward by the
cylinder 45.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a printing machine the combination of a movable blade, flyer or pusher,
with a set of movable partitions which move either in a straight line and in two
arcs of circles, or in an are of a circle, in order to enclose between them packets
of a given number of sheets.
2. The combination of a movable blade, flyer or pusher, which strikes the sheets,
with a cord or band actuated intermittently, so as to produce on the latter packets
of sheets separated from each other.
3. The combination with a delivery blade, flyer or pusher, of a prism serving as
a stop for sheets pushed along by the blade or flyer, and which is actuated so as to
present another of its sides as a stop when the preceding side has collected the
desired number of sheets, and with an endless band or belt carrying forward the
packets as same are removed.
4. The combination with a delivery blade, flyer or pusher, which forces the
sheets against a fixed stop, of grippers describing arcs of circles, or ares of circles
and straight lines, and which remove the packets of sheets as they are formed,
such grippers themselves being combined with an endless belt on which they deposit
the packets, or with a table which is displaced laterally so as to separate the
