WILLIAM CONQUEST of Tudor Street in the City of London, Mechanical
Engineer, IMPROVEMENTS IN SHEET DELIVERY APPARATUS FOR PRINTING
MACHINES." [communicated to him from abroad by Messieurs R. Hoe and Company
of the City and State of New York United States of America]
This invention relates to sheet delivery apparatus to be applied to web printing
machines, more particularly to those machines for printing eight pages of news-
paper or other printed matter, or printed matter in which two or more sheets have
to be associated to make up the newspaper or pamphlet.
It is well known that in web printing machines, the speed at which the printed
matter is produced is extremely rapid, and when it is necessary to associate two or
more sheets to form, say, a newspaper complicated arrangements of turning
mechanisms and collecting cylinders have been required for effecting the operation
known as "insetting" by which the successive sheets are brought together so as
to lie over each other previous to further manipulation.
"
Now the object of the present invention is to simplify the mode of "insetting'
hitherto employed, and consists in a novel arrangement of tapes whereby two
pathways of travel of unequal lengths for the sheets are provided, such pathways
acting to superpose the sheets fed into them alternately, and thus the collection or
association of the sheets is effected previous to being folded.
In carrying out this invention two sets of tapes consisting of a main and an
auxilliary tape are employed, two successive sheets being guided alternately to each
set. Each set of tapes is combined with a pair of folding rollers and a vertically
descending folding blade, so placed in relation to the tapes as to give a longitudinal
fold to the sheets being carried forward by the tapes. The folding rollers are
driven in any convenient manner from the printing machine and the folding blade
is actuated by suitable gearing or other mechanism which is properly timed to
effect the desired object.
The printed web is first presented to cutting cylinders to be cut into sheets and
on leaving these cylinders the sheets enter between a pair of forwarding rollera

page_text: round which the main tapes pass. As it will be necessary to refer to a number of
rollers to properly describe the arrangement of the tapes I will for convenience
apply to the rollers reference numbers. I will also refer to the tapes by letters;
thus, the forwarding rollers will be named 1 and 2 and the main tapes A and B.
Tape A passes round roller 1 and main tape B round roller 2. From these
rollers the main tapes pass between a pair of rollers 3 and then divide, A going
upwards and B downwards. In rear of the rollers 3 a switch is placed which
serves to direct the sheets to one or other of the folding devices as required. In
rear of the switch is arranged a pair of rollers 4 4*. I will now trace the path of
the main tape A. From roller 3 it passes over roller 4 to a roller 5 situate in
advance of one end of the folding rollers, thence in a horizontal direction pass the
folding device to and under a roller 6; over a roller 7 and under a roller 8 placed
below and nearly in the same vertical plane as 7. The tape A then passes over a
roller 9, again past the folding device, but at a lower level, to a roller 10 between
the roller 5 and the end of the folding rollers. From 10 it returns to and under a
roller 11 at the opposite end of the folding rollers and over rollers 12 and 13 to 1.
At roller 4 the main tape A meets an auxilliary tape which I will call A¹ and
which passes by the path 5. 8. 9. to and over a roller 14 placed between 5 and 10,
and thence under roller 15 back to 4. Between rollers 4 and 8, the tape A¹ will
underlie the main tape A but from 8 to 10 it will overlie A.
Between rollers 7 and 8 is arranged a combined stop and switch the use of which
will be presently referred to. This switch is pivotted in rear of 7 and 8 and is
actuated in any convenient manner.
Now suppose it is desired to superpose two sheets and fold them with a longi-
tudinal fold the two sheets will pass in succession between rollers 3, will be guided
say, upwards by the switch and will be caught between the tapes A A¹ at roller 4.
The first sheet which will be the outside sheet will pass by the path 5. 6. 7. 8. 9
and 10 the stop switch being raised to allow it to pass. When the sheet arrives a
second time over the folding rollers it will be stopped by a suitable fixed stop as is
well understood.
In the meantime the second sheet which will form the inside sheet will pass by
the path 5 and 6 but before it arrives at the roller 6 the stop switch will be
operated to stop it. It will thus be brought over the first sheet and arrested, and
the folding blade will then be caused to descend. The double sheet will thus be
forced into the grip of the folding rollers from which the folded sheet will be
carried off in any convenient and well known manner, either to a piling board, or
to be subsequently folded as desired.
While the above operations have been taking place the position of the switch at
rollers 3 will have been changed to guide the two suceeding sheets which I will
term the third and fourth sheets downwards to the second folding apparatus. The
folding rollers and blade of this apparatus will be placed preferably immediately
below those of the first apparatus.
The main tape B as before stated passes downwards after leaving rollers 3, under
rollers 4* 5*, round 8* over 9* 14* and 15%, to 2; it will in fact take the path
corresponding to A¹
In this set the position of the auxilliary tape which I will term B¹ will be
exactly opposite to that of tape A¹; thus when tapes B B¹ come together at
roller 4*, tape B¹ will overlie B.
This auxilliary tape B¹ will pass from 4* under 5* and 6× round 7* under 8*
over 9* and 10x back to 11*; over 12* under 13* to 4* With the exception of
15 and 13* the relative positions of all these rollers will be the same as that
described with reference to the first set of tapes. In the second set a fixed stop
and a stop switch are provided and the mode of associating the sheets will be the
same as that before described.
By the above described arrangement of sheet delivery apparatus the printed
sheets may be associated and delivered once folded with great rapidity and the
risk of their jamming in the printing machine will be obviated.

page_text: In some cases it may be found desirable to employ a pair of auxilliary tapes in
lieu of one by which means the combined stop and switch will be despensed with
two fixed stops, one placed at either end of the folding rollers being used in lieu
thereof.
In this arrangement roller 5 will be duplicated and a switch will be placed
between these two rollers to direct the sheets alternately into a long and a short path
A single roller 6 will take the place of 6. 7. 8 and 9. Rollers 10, 11. 12 and
13 will be the same as in the first arrangement the main tape A passing from 13.
back to 1. The auxilliary tape A¹ will meet A at roller 4 and after passing with
it between rollers 5 will separate passing round roller 7 placed in front of roller 5,
thence across the folding rollers round a roller 8 placed in front of 6 and back round
a roller 9 running in conjunction with the duplicate 5 at which roller it again
meets the main tape A and runs with it round 6 and thence by roller 14 back to 4.
The auxilliary tape A' will pass round the roller 7 underlying the tape A' round
roller 8 under roller 9 back to 7.
In this case the first sheet will pass from rollers 5 round 6 and over the folding
rollers and will be stopped by a fixed stop at the opposite end of the folding rollers
passing on its way under a stop bridge.
The second sheet will after passing rollers 5 be switched round 7 and will be
brought in the contrary direction and be stopped above the first sheet by the stop
bridge before mentioned. The folding blade will then descend and fold the two
sheets together into the bite of the folding rollers.
The two pathways will be so regulated that the two sheets will reach their
respective stops at the same moment. The second set of tapes will be arranged
practically in the same manner as that above described but the main tape B. will
take after leaving the rollers 3 a course corresponding somewhat to that taken by
A¹ above referred to, while the auxilliary tape B' will take a course corresponding
somewhat to that taken by the main tape A. The course of the auxilliary tape Br
will be similar to that taken by A². The sheets may if desired be brought in the
same direction into the position for folding and this will be effected by arranging
the tapes, so that the long pathway of the first sheet shall pass over a roller placed
above the short pathway at such a distance that the leading edge of the first sheet
shall be timed to correspond to the leading edge of the second sheet and both will
advance together until stopped by a fixed stop.
In this arrangement in place of one pair of rollers 4 4* two pairs will be used
and in rear of each pair a switch will be provided which will be actuated to guide
a sheet alternately into the long and short pathways. The main tape A will be
taken through the pair of rollers 4 and the main tape B through the pair of
rollers 4*.
Two auxilliary tapes will be required one A¹ to meet the main tape A and carry
forward the first sheet and one A² to carry forward the second sheet, conductors or
fixed guides will also be used in lieu of a second auxilliary tape.
It will be understood that the above named arrangements of tapes may be
combined with the cutting cylinders or with cutting and collecting cylinders or
with collecting cylinders or with a rotary folding machine.
The sheets may be switched on to a rotary gathering cylinder from which they
may be stripped by a pair of switches acting to guide the sheets direct into the
long and short paths or the sheets may be removed from the cylinder by a single
switch arranged to deliver them on to a rocking plate for the long path and between
a pair of rollers for the short path.
With two sets of tapes and folding apparatus the arrangement of which is
modified to suit the altered positions the sheets may be delivered and folded with
great speed.

"IMPROVEMENTS IN SHEET DELIVERY APPARATUS FOR PRINTING MACHINES:
"
a Communication to me from Abroad by Messieurs R. Hoe and Company of the
City and State of New York United States of America
This Invention relates to sheet delivery apparatus to be applied to web printing
machines more particularly to those machines for printing eight pages of paper or
other printed matter or printed matter in which two or more sheets have to be
associated to make up the newspaper or pamphlet.
It is well known that in web printing machines the speed at which the printed
matter is produced is extremely rapid and when it is necessary to associate two
or more sheets to form say a newspaper complicated arrangements of turning
mechanisms and collecting cylinders have been required for effecting the operation
known as "insetting" by which the successive sheets are brought together so as to
lie over each other previous to further manipulation.
Now the object of the present Invention is to simplify the mode of " "insetting"
hitherto employed and consists in novel arrangements of tapes whereby two
pathways of travel of unequal lengths for the sheets are provided such pathways
acting to superpose the sheets fed into them alternately and thus the collection or
association of the sheets is effected previous to being folded.
In the accompanying Drawings several arrangements of tapes and rollers are
shown by which the object of the Invention may be attained. Sheets I II and III
illustrate arrangements for "insetting" and folding suitable for receiving the sheets
direct from the cutting cylinders of the web printing machine and Sheets IV and V
show in diagram arrangements of the insetting and folding mechanism combined
with collecting and rotary folding mechanism respectively.
Referring to Sheet I which shows in diagram an arrangement of tapes in which
a combined stop and switch is used two sets of tapes each consisting of a main and
an auxiliary tape are employed, two successive sheets being guided alternately to
each set Each set of tapes is combined with a pair of folding rollers and a
vertically descending folding blade so placed in relation to the tapes as to give a
longitudinal fold to the sheets being carried forward by the tapes. The folding
rollers are driven in any convenient manner from the printing machine and the
folding blades are actuated by suitable gearing or other mechanism which is
properly timed to effect the desired object.
The printed web is first presented to cutting cylinders to be cut into sheets and
on leaving these cylinders the sheets enter between a pair of forwarding rollers
round which the main tapes pass.-1 and 2 are the forwarding rollers, and A and B
the main tapes. The tape A passes round roller 1 and main tape B round roller 2.
From these rollers the main tapes pass between a pair of rollers 3 and then divide,
A going upwards and B downwards.-In rear of the rollers 3 a switch C is placed
which serves to direct the sheets to one or other of the folding devices as required.
In rear of the switch is arranged a pair of rollers 4, 4*.
I will now trace the path of the main tape A; From roller 3 it passes over
roller 4 to the roller 5 situate in advance of one end of the folding rollers C¹ thence
in a horizontal direction past the folding device C¹ to and under the roller 6 over
the roller 7 and under the roller 8 placed below and nearly in the same vertical
plane as the roller 7.-The tape A then passes over the roller 9 again past the
folding device but at a lower level, to the roller 10 placed between the roller 5 and
the end of the folding rollers C.-From 10 it returns to and under the roller 11 at
the opposite end of the folding rollers and over the rollers 12 and 13 back to 1.

page_text: At the roller 4 the main tape A meets the auxiliary tape A¹ which passes by the
path formed by the rollers 5, 8, 9 to and over the roller 14 placed between 5 and 10
and thence under the roller 5 back to the roller 4. Between the rollers 4 and 8 the
tape A will underlie the main tape A but from 8 to 10 it will overlie the tape A
Between the rollers 7 and 8 is arranged a combined stop and switch D the use of
which will be presently referred to.-This switch is pivotted in rear of the rollers 7
and 8 and is actuated by the usual mechanism or in any convenient manner.
Now suppose it is desired to superpose two sheets and fold them with a
longitudinal fold the two sheets will pass in succession between the rollers 3
will be guided say upwards by the switch C and will be caught between the
tapes A A' at roller 4 The first sheet which will be the outside sheet will pass by
the path formed by the tapes A A¹ and rollers 5, 6, 7, 8; and 9 the stop switch D
being raised to allow it to pass.-When the sheet arrives a second time over
the folding rollers it will be stopped by a suitable fixed stop D₁ as is well
understood. In the meantime the second sheet which will form the inside sheet
will pass by the path formed by the tapes A and A¹ and the rollers 5 and 6 but
before it arrives at the roller 6 the stop switch D will be lowered to stop it. It will
thus be brought over the first sheet and arrested and the folding blade will then be
caused to descend The double sheet will thus be forced into the grip of the folding
rollers C from which the folded sheet will be carried off in any convenient and
well known manner either to a piling board or to be subsequently folded as desired.
While the above operations have been taking place the position of the switch C
at rollers 3 will have been changed to guide the two succeeding sheets which I will
term the third and fourth sheets downwards to the second folding apparatus.-The
folding rollers and blade of this apparatus will be placed preferably immediately.
below those of the first apparatus.
The main tape B as before stated passes downwards after leaving rollers 3 under
rollers 4* 5* round 6* over 7* under 8* over 9* 14* and 15* to the roller 2, it will
in fact take the path corresponding to the tape A-In this set the position of the
auxiliary tape which I will term B' will be exactly opposite to that of tape A¹
thus when tapes B B¹ come together at roller 4* the tape B¹ will overlie B.-The
auxiliary tape B¹ will pass from the roller 4* under the rollers 5* and 6* round 7×
under 8* over 9* and 10* back to 11* over 12* under 13* to 4*.-With the
exception of the rollers 15* and 13% the relative positions of all these rollers, will
be the same as that described with reference to the first set of tapes In the second
set a fixed stop D¹x and a stop switch D* are provided and the mode of associating
and folding the sheets in pairs will be the same as that before described.
By the above described arrangement of sheet delivery apparatus the printed
sheets may be associated and delivered once folded with great rapidity and the risk
of their jamming in the printing machine will be obviated
In some cases it may be found desirable to employ a pair of auxiliary tapes
instead of a single tape by which means the combined stop and switch will be
dispensed with two fixed stops one placed at either end of the folding rollers being
used in lieu thereof.
In Sheet II of the Drawings this arrangement is shewn in diagram the roller 5
will be duplicated and a switch E will be placed between these two rollers to
direct the sheets alternately into the long and the short path. A single roller 6
will take the places of the rollers 6, 7, 8, and 9.-The rollers 10, 11, 12, and 13
will be similar to the first arrangement shewn in Sheet I the main tape A passing
from the roller 13 back to 1.-The auxiliary tape A¹ will meet the tape A at the
roller 4 and after passing with it between rollers 5 will separate passing round the
roller 7 placed in front of the roller 5 thence across the folding rollers C¹ round
the roller 8 placed in front of the roller 6 and back round the roller 9 running in
conjunction with the duplicate roller 5 at which roller it again meets the main
tape A and runs with it round 6 and thence by the roller 14 back to the roller 4.—
The auxiliary tape A' will pass round the roller 7 underlying the tape A¹ round
roller 8 ander roller 9 back to 7.-In this case the first sheet will pass from

page_text: rollers 5 round the roller 6 and over the folding rollers and will be stopped by a
fixed stop D¹ at the opposite end of the folding rollers passing on its way under
a stop bridge D.-The second sheet will after passing the rollers 5 be switched
round the rollers 7 and will be brought in the contrary direction and be stopped
above the first sheet by the stop bridge D before mentioned.-The folding blade
will then descend and fold the two sheets together into the bite of the folding
rollers.C¹.
The two pathways are so regulated that the two sheets will reach their
respective stops D¹ D³ at the same moment.
The second set of tapes will be arranged practically in the same manner as that
above described but the main tape B will take after leaving the rollers 3 a course
somewhat corresponding to that taken by the tape A¹ above referred to while the
auxiliary tape B will take a course corresponding somewhat to that taken by the
main tape A. The cause of the auxiliary tape B³ will be similar to that taken
by A²
The sheets may if desired be brought in the same direction into the position for
folding and this will be effected by arranging the tapes so that the long pathway
of the first sheet shall pass over a roller placed above the short pathway at such a
distance that the leading edge of the first sheet shall be timed to correspond to the
leading edge of the second sheet and both will advance together until stopped by a
fixed stop.
This arrangement is shewn in Sheet III where in place of the pair of rollers 4, 4*
two pairs of rollers 4. 4 and 4* 4* are used.-In rear of each pair of the rollers 5, 5
and 5* 5* a switch F F is provided which will Le actuated to guide a sheet
alternately into the long and short pathways.-The main tape A will be taken
through the pair of rollers 4 and the main tape E around the upper roller of the
pair of rollers 4*.-In the upper set two auxiliary tapes will be required one A¹ to
meet the main tape A and carry forward the first sheet and one auxiliary tape A¹
to carry forward the second sheet; conductors or fixed guides G will also be used
to assist the auxiliary tapes.
It will be seen that this arrangement requires an additional tape B* to bring
the sheets to the rollers 4* 4* and that the tape B passes from the roller 4* to the
rollers 5* and after assisting with the tape B in forming the long path it is
returned to and around the upper of the pair of rollers 4*. The tapes B¹ B² are
similarly arranged
The above described arrangements of tapes may be combined with the cutting
cylinders or with cutting and collecting cylinders or with collecting cylinders or
with a rotary folding machine.
The sheets may be switched onto a rotary gathering cylinder from which they
may be stripped by a pair of switches acting to guide the sheets direct into the long
and short paths or the sheets may be removed from the cylinder by, a single switch
arranged to deliver them onto a rocking plate for the long path and between a
pair of rollers for the short path.
In Sheet IV other arrangements of tapes and rollers are shown in combination
with rotary gathering cylinders.-In the upper half of the figure the cylinder H is
shewn as provided with a single switch I arranged to deliver the collected sheets
on to a rocking plate K to guide the sheets into the long and short paths-In
the lower half of the figure the cylinder is shewn as provided with a pair of
switches L L¹ for the like purpose, and the rotary collecting cylinder H is supplied
with the tapes necessary to it as a collecting mechanism. These tapes consist of a
set A that extend from a roller as 1 between the pairs of rollers 3 and 4 over a
portion of the cylinder and return over the roller 6 and guiding rollers 7 and 8.—
A companion set of tapes A* runs from a roller as 4 to and returns over a
roller 5. These last tapes though coacting with the tapes A to conduct the sheets
from the cutting cylinders to the collecting cylinder do not reach the latter cylinder
but the space between their roller 5 and the periphery of the cylinder H is spanned
as is common by conductors G.-A great portion of this cylinder H is embraced bý

page_text: tapes A** which run around a portion of the surface of the cylinder and return
over guide rollers.
The space between the roller 6 and one of the guide rollers is covered by
switches I the front faces of which are curved to coincide with and be a slight
distance from the periphery of said cylinder when the switch stands as shown and
the points enter into grooves formed circumferentially in the adjoining rollers and
the cylinder H as said switches are vibrated to direct sheets around the cylinder H
or strip the same therefrom Successive sheets fed to this cylinder and carried onto
its surface between the tapes A and conductors G will when the switches stand as
shewn in the upper part of the figure be directed around with the cylinder.- When
the head of the first sheet passing around this cylinder reaches the entrance point
a second sheet will be received upon it and the two will pass around the cylinder,
in like manner receiving if desired a third and fourth and so on.-When the proper
number of sheets have thus been collected and the tail ends of such collected sheets
have passed the points of the switches I the switches will be rocked so that their
points will lie within the grooves in the periphery of the cylinder H thus entering
beneath the heads of the pack of sheets thereby causing such pack to follow the
upper faces of the switches and be stripped or directed off from the cylinder H into
a free channel the entrance of which is formed by the roller 6 and the upper faces
of these switches.-The delivery mechanism as shown in this figure is provided as
before with two sheet conducting pathways constituted by the tapes A¹ A' and A³
which carry the sheets while travelling in opposite directions to a proper position
between the folding blade and the folding rollers the said sheets being properly
arrested by the stops D' Ds as before explained These switches I and rocking
plate K are rocked at suitable periods of time by means of properly shaped and
driven cams the structure and operation of which being well understood need not
be described.
This arrangement is provided with stops D¹ D³ and conductors G.-When the
switches I stand in the position shown the sheets collected upon the cylinder H and
guided therefrom by the switches I when in their forward position will be directed
between the conductors and the face of the rocking plate K into the upper sheet
conducting pathway and will thereby be carried onward until arrested by the
stop D' so that they lie over the folding rollers.-As the succeeding pack of sheets
is stripped from the cylinder H and then vibrated, the sheets will pass between the
roller 6 and the upper faces of the switch I and be directed into the lower sheet
conducting pathway and carried thereby outward until arrested by the stop D'
when they will lie over the folding rollers immediately beneath the pack of sheets
lying in the upper sheet conducting pathway-The two packs of sheets may then
be simultaneously doubled into the nip of the folding rollers by a single descent of
the folding blade as before explained.
It will be apparent that two three or any desired number of sheets may be
collected upon the cylinder and packs so composed be delivered successively into
the upper and lower sheet conducting pathways.-Thus by this arrangement of
mechanisms any number of sheets may be brought together to be folded as a single
product. In the lower part of this figure the switches L and L' are arranged to
directly cooperate with the cylinder H in stripping the sheets therefrom and in
which the upper and lower sheet conducting channels lead outward one above the
other directly over the folding rollers.-In other respects the taping is somewhat
similar to that shewn in the upper part of the figure but in this instance instead of
upper tapes cooperating with the carrying tapes to form two pathways, conductors
are used.
The cylinder H is capable of collecting any number of sheets as before described
and when the predetermined number has been collected the switches L which
together with the switches L' stand during the collecting operation with their
forward faces coincident with the periphery of the cylinder will be properly vibrated
forward so as to stand in the position shown and thereby strip or guide the pack
of collected sheets off from said cylinder and cause it to pass under the roller 6*

page_text: J
and thence outwardly over the folding rollers until it is arrested by the stop D³× -
As soon as the pack of sheets has cleared the switches L said switches will be
rocked rearwardly so that their forward faces will again stand coincident with the
periphery of the cylinder H and aid in the collection of another pack of sheets. -
When this pack has been collected the switches L¹ will be vibrated forward and
thereby intercept the pack of sheets and guide it over their upper curved faces and
thence onto the tapes which will carry it outward over the folding rollers until it is
arrested by the stop D2x under the preceding pack which has in the meantime been
lying against the stop waiting for it the two packs of collected sheets thus being
brought into proper superposed position to be folded together as a single product
by the simple descent of the folding blade.-I would here remark that either of the
arrangements of tapes above described may be used in duplicate
In Sheet V of the Drawing is shown a further modified form of apparatus the
sheets being associated and delivered together first folded transversely.-This is
accomplished by means of a rotating folding blade m that is supported by a
cylinder M the latter also having grippers n by which the leading end of the sheet
is controlled. The tapes A' and A² are so disposed as to form a continuous pathway
into which the sheets enter and which has an upper and a lower portion the latter
of which runs rearwardly.-The sheets in passing from the upper to the lower
portion of the pathway are guided by the lower curved surface of a set of suitably
placed vibrating switches D.-The long points of these switches are so shaped as to
form sheet stops and they are vibrated alternately into and out of the upper pathway
by a suitable cam which is so shaped and timed as to rise to the position shewn by
the dotted lines and let one sheet pass on into the lower pathway and be arrested
over the folding rollers by the stop D' and to fall to the position shown by the full
lines and arrest the succeeding sheet in the upper pathway directly over the first
sheet;
and the length of the pathway is such that the two sheets will arrive at
their respective stops at about the same time and they will then be in position for
simultaneous delivery by the folding blade.-A sheet fed to the cylinder M by the
tapes A and A* will be seized by the grippers n and carried around until its central
portion arrives before the rollers N N when the grippers will release it and the
folding blade m will operate to double it between the said rollers.-In this doubled
condition the sheet will be carried outward by the tapes A' A' and the switches
being raised above said tapes as shown by the dotted lines will guide the sheet
rearward over the folding rollers until it is arrested by the stop D'.-The succeeding
sheet folded by the blade m of the cylinder M between the rollers N N will be
carried by the tapes outward until it is arrested by the switches D which as soon
as the first sheet clears them will be vibrated into the position shown to intercept
the said sheet.-The two folded sheets will then lie one above the other over the
folding rollers and be doubled or folded simultaneously at right angles to their first
folds by a single descent of the folding blade.
In the lower half of the figure the mechanism is similarly arranged but the
tape B corresponds in position to a portion of the tape A and the tape B after
assisting in leading the sheets from the cutting cylinders to the rollers 3 and 4* is
carried down to a guide roller mounted close to the folding cylinder M and onto
which the sheets are lead by a conductor and the tape B* the tape B returning to
the roller 2.
