Improvements in Delivery Mechanism for Web Printing Machines.
I HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of Middlesex, Civil 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 :—
This invention relates to a mechanism especially adapted and designed for use in
connection with wel-printing machines, whereby printed products of various sizes or
volumes may be produced.
For convenience, the term web will be hereinafter used in referring to the material
operated upon, but it is understood that by properly taping the folder, detached sheets
may be manipulated.
As a full understanding of the invention can best be given by illustrations and
detailed description, all preliminary description will be omitted, and description given
with reference to the accompanying drawings, in which Fig. 1 is a side elevation of a
mechanism embodying the invention (parts of the framework being broken away). In
this, as also in the remaining views of the drawings, the gearing, and many of the
minor details of the mechanism, are omitted, as such parts can readily be supplied by
any ordinarily skilful mechanic, and if shown, would only tend to create confusion. ✓

upon a two-third width web.
Figs. 37 and 38 illustrate a double folder for a wider web.
Fig. 39 is a perspective view of a detail which will be referred to.
Referring to said drawings, it is to be understood that the printing mechanism is of
substantially the ordinary form, consisting of form cylinders A, impression cylinders B,
and inking mechanism represented by the rolls and cylinders C, all of which are
arranged in the usual manner, and are of sufficient length to capacitate the machine
to operate upon a double width web.
The web D is led from a roll, and after passing between the first form and
impression cylinders, to be printed upon one side, is led between the second form and
impression cylinders, to be printed upon its other side, and then passes over a roll 50,
where it is operated upon by a slitter 49, and split into two longitudinal sections or
narrow webs d, which narrow webs are then led to the delivery mechanism.
The delivery mechanism, as herein illustrated, consists of a web-turning, or turning
and associating mechanism, of ordinary form, composed of two web turners 47, two
longitudinal folders G, H, a transverse cutting, folding, and associating mechanism,
composed of two cylinders 45, 46, and a sheet-piling mechanism, composed of a rotary
S-shaped fly 53, and a series of slowly moving belts or tapes 54.
The web turners 47, composing the web-turning and associating mechanism, are
arranged obliquely across the paths of the webs d, so that when the two webs are led
around their respective turners, they will be turned at right angles to their previous
course, and brought one directly beneath the other. The web turners 47 are
adjustable, so that they can be shifted to secure the proper adjustment.
The folder G is of substantially the form and construction illustrated and described
in the specification of the Letters Patent granted to William Conquest, and dated
December 5th 1885, No. 14,948. It may, however, be of any other suitable form.
The external turners 20, and also the fold-laying rolls 23, which co-operate with this
folder, are, however, for a purpose that will presently appear, made slightly longer
than in the construction shown in said Letters l'atent.
The folder H is located upon the outside of the framework of the machine, in a
position substantially at the side of the folder G. This folder (see Figs. 4, 5, and 6)
consists of an internal plate h, arranged in a slightly inclined position, and turned
inward at its lower end, so as to provide an internal guide 9, to act upon one-half the
width of the web, and is cut away on one side, so as to form an oblique-internal guide 8,
for the other half of the width of the web. The internal guide 9 is, as will be
observed, arranged at right angles to the travel of the web. This plate h is supported,
at its base, upon arms 18, which are loosely mounted upon the bushings of the shaft

page_text: of a roll 19, located at the base of the plate, and is adjustably supported at its lower
end by means of a rod 17 extending from the framework of the machine.
Co-operating with the plate h, is an external plate g, which extends along the oblique
guiding edge 8 of the plate 4, and inward, and is formed at its lower edge to provide
an external turner 10, which acts to turn the half of the web which passes over the
guiding edge 8 inward, and double it over onto the other half of the web, as
indicated in Fig. 1.-The plate y is also adjustably supported by rods 16, extending
from the framework of the machine.
The two folders G, H, are positioned with relation to each other so that the two
webs, after being longitudinally folded, will, as they pass between the fold-laying
rolls 23, overlap, with the folded edge of each projecting beyond the unfolded edge of
the other. Located between the folder H, and the fold-laying rolls 23, is a guide
roll 15, over which the web folded by the folder H is led as it passes to the
rolls 23.
The folder H is adjustable to enable it to properly fold webs which vary somewhat
in width, to permit which, the arms 18 are adjustable upon their supporting bushings,
while the openings in the framework which receive the rods 16, 17, are elongated to
permit a corresponding movement of the webs.
The cutting, folding, and associating mechanism, is composed of two cylinders
45, 46, and a pair of folding rolls 14, which are equipped and operate upon the same
general plan shown and described in the letters patent above referred to. The details
of the equipment of the cylinders 45, 46 are, however, somewhat different from what
is shown in said Letters Patent, and will be described.
The cylinder 46 (see Fig. 16) is of a circumference equal to the length of two of
the sheets to be produced, and is provided at opposite points with two cutting
grooves 2, and at the proper points between these grooves, with a pair of rotary
folding blades 4, which operate in the usual manner to fold the sheets from the
cylinder into the bite of the folding rolls 14. The cylinder 46 is also provided with
two sets of sheet-holding pins 3, which are located just in the rear of the cutting
grooves 2. These pins pass through openings in the periphery of the cylinder, and
are pivotted in the ends of arms extending from rock-shaft 28, journalled in the head
of the cylinder, and provided with arms 29, having studs or bowls, which are engaged
by a stationary cam 30, in such manner as to retract the pins at the proper times.
The pins are normally held in their protruded position by means of springs 31, which
act upon rods 32, which are pivotted to arms extending from the shafts 28, and pass
through guides 33 near the cylinder head. In order to hold one set of pins
permanently retracted, which will sometimes be necessary, as will be hereinafter
explained, the rod 32 of that set of pins is provided with a latch 34, which is
arranged to engago with the guide 33, so as to hold the rod and prevent the spring 31
from protruding the pins. This latch forms no part of the present invention, and
may be of any suitable or convenient construction.
The cylinder 45 is of a circumference slightly less than one-half the circumference
of the cylinder 46, and is provided with a cutting-blade 5 of the ordinary form, which
is arranged to co-operate with the grooves 2 in such manner as to sever a sheet from
each web at each revolution of the cylinder 45. This cylinder is also provided with one
set of impaling pins 6, which are pivotted upon arms extending from a rock-shaft 35,
which is journalled in the heads of the cylinder, and is provided with an arm 36,
having a stud or bowl which travels on a con-excentric guide 37. The guide 37 is
provided with a shifting cam 38, which is arranged to direct the bowl of the arm 36
from the inside to the outside, and vice versa, of the guide, and thus rock the shaft 35,
and retract and protrude the pins 6 at the proper times. The movement of the arm 36
is limited in each direction by stops 48 projecting from the cylinder head. The
proper movement of the switch 38 is imparted from a crank pin 39 upon the shaft of
the cylinder 46, which is connected by a rod 40 with an arm 41 extending from the
pivot of the switch 38.
It will sometimes be necessary, as will be hereinafter explained, to hold the pins 6

page_text: permanently retracted. To effect this, the rod 40 will be disconnected from the crank
pin 39, and hooked onto a stationary stud 42, provided for that purpose. When the
rod 40 is thus hooked onto the stud, the switch 38 will be held in a central position
(see dotted lines in Fig. 18), so that the bowl of the arm 36 will be prevented from
passing to the inside of the guide 37, and the pins will, as a consequence, remain
retracted.
The delivery mechanism thus organized is capacitated, by slightly different
adjustments, to deliver the full capacity of the printing machine either in the form
of one, two, or four-sheet products folded once longitudinally and once transversely ;
or three-fourths the full capacity of the printing machine, in products consisting of
one full and one half-sheet, or two full and two half-sheets, folded to the same
dimensions.
The operation of the mechanism, in delivering these different products, is as
follows:
If it is desired to utilize the full capacity of the printing machine in producing
the four-paged papers, that is to say, papers consisting of one full sheet, the
folders G, H, will both be used; the pins 6 of the cylinder 45 will be permanently
retracted, and both sets of pins of the cylinder 46 will be rendered operative.
The full width web D will be used, and after being printed, it will be split, and
one of the webs d will be led around the inner one of the turners 47, and
thence around the roll 22, to the longitudinal folder G, and thence, after being
longitudinally folded, to the cylinders 45, 46. The other web d, instead of passing
around the other turner 47, will pass directly forward over the roll 19, and down-
ward over the folder H. As the web passes over the plate h, the inner half of
the web will be acted upon by the edge 10 of the plato g, and turned inward around
the oblique guiding edge S, so as to be laid over onto the other half of the web, thus
folding the web longitudinally. The web thus folded will then be led over the roll 15,
and between the fold-laying rolls 23 to the cylinders 45, 46.
It will be observed, as before stated, that the two folders G, H, are so positioned
that the two webs, as they pass between the fold-laying rolls 23, are overlapped, as
indicated in Figs. 3 and 24. In this condition the two webs will pass into the bite
of the cylinders 45, 46, where the leading ends of the webs are taken by one set of
the pins 3, and carried around upon the cylinder 46 until the folding blade 4 arrives
in proper position to fold the sheets between the rolls 14, when the pins will be
retracted, and the blade operated to fold the sheets between the rolls. Just previous
to this, the blade 5, co-operating with the groove 2, will have severed the sheets,
leaving the freshly severed ends of the webs impaled upon other set of pins 3, and
the operation will bo repeated.
After passing the rolls 14, the sheets will emerge in the condition shewn in Fig. 25,
and will then pass into the control of the tapes 7, and be conveyed to the fly 53,
and by it piled upon the belts 54 in the usual manner. The mechanism may also be
provided with a counting mechanism 13, similar to that described in the above-
mentioned Letters Patent granted to William Conquest December 5th 1885,
No. 14,948, which will operate to divide the sheets into lots of any desired number.
By reference to Fig. 25, it will be seen that the two products, each consisting of a
single sheet, are delivered one partially within the other. If the two webs passed
between the fold-laying rolls 23 and the cylinders 45, 46, in such position as to be in
line with each other, then the two products would, when they received their transverse
fold, be folded wholly one within the other, and if this were the case, the operation of
separating the two products, which of course is necessary, would be slow and difficult;
but the sheets not being wholly one within the other, it becomes possible to separate
them readily by simply grasping the folded edges of the two sheets, and drawing
them apart, and this can be done by taking the sheets in packs of twenty or more at
a time. This operation of separating the sheets is also rendered much easier by
reason of the fact that the sheets are overlapped at their free edges.
This peculiar manner of delivering the sheets greatly simplifies the delivery

page_text: mechanism, as by this means the single transverse cutting, folding, and associating
mechanism, by being very slightly increased in length, is enabled to operate upon both
webs, and thus an extra mechanism of this character is avoided.
If it is desired to utilize the full capacity of the printing machine in producing two-
sheet or eight-page products, the operation may be exactly the same, except that the
wob d, which in the case just described passes over the folder H, will be led around
its turning bar 47, and thence around the roll 21, which is adjustable to secure the
proper register, so as to be superimposed upon the other web, in which condition the
two associated webs will pass over the folder G. The product, in this case, will be
delivered in the form shown in Fig. 20.
When it is desired to utilize the full capacity of the printing machine in producing
products consisting of four sheets or sixteen-page papers, the operation will be the
same as in producing the two-sheet product just explained, except that the rod 40
will be hooked onto the crank pin 39, so as to render the pins 6 of the cylinder 45
operative, and one set of the pins upon the cylinder 46 will be rendered inoperative
by being held retracted, as shewn in Fig. 16. As the leading ends of the associated
and longitudinally folded webs arrive at the bite of the cylinders 45, 46, the cam 38
will have been rocked to the position shown in Fig. 10, so as to direct the bowl of the
arm 36 to the inside of the guide 37, and protrude the pins 6, which pins will then
take the leading ends of the webs, and carry them around upon the cylinder 45, until
that cylinder has completed a rotation, when the webs will be severed by the blade 5,
and the cam 38, having by this time been rocked to the position shewn in Fig. 18,
the bowl of the arm 36 will be directed to the outside of the guide 37, so as to retract
the pins 6, and release the ends of the webs. Just beforo or just after this takes
place, the operative set of pins 3 of the cylinder 46, will take the webs, and also the
forward ends of the two sheets, upon the cylinder 45, and carry the ends of both the
webs and the sheets forward upon the cylinder 46, so that the sheets will become
associated with the leading ends of the webs. When the cylinder 46 has made a balf
revolution from this point, the blade will again sever the webs, the pins 6 taking the
freshly severed ends, and the pins 3 will be retracted, to release the forward ends of
the associated pairs of sheets, and the blade 4 will be operated to fold them transversely
between the rolls 14. The product thus produced will consist of two pairs of longitu-
dinally folded sheets associated and folded transversely together as indicated in
Fig. 19.
To produce products consisting of one full-sheet and one half-sheet, the adjustment
and operation will be the same as in producing products consisting of two full-sheets,
except that the web D will be of three-fourths width, so that one of the webs d will
be half-width. The webs will then he associated and folded as indicated at. Fig. 20.
To produce products consisting of two full-sheets and two half-sheets, such as shown
in Fig. 21, the adjustment and operation will be the same as in the case of the four-
sheet product, except that the web D will be of three-fourths width.
Products consisting of two full-sheets may also be produced, as shown in Fig. 22,
by using a web D of half-width, and operating the cylinders 45, 46, the same as in
producing the four-sheet product; or, as shown in Fig. 23, by using a web D of full
width, leading one of the webs d over each longitudinal folder, and operating the
cylinders 45, 46, in the same manner.
Still other variations in the size and form of the product produced may be obtained
by increasing the circumferential capacity of the printing cylinders, and by arranging
the mechanism for operating the pins and folding blades so as to associate three or
more sheets or pairs of sheets.-This can readily be done by any ordinarily skilful
mechanic, if any such range of capacity should be desired in any particular case.
Still greater capacity and range in the size of the product may be obtained by using
a supplement web in addition to the main web, and such supplement web can be
supplied from any supplement printing mechanism located at the side of the delivery,
or in any other convenient position. When a supplement web of one-half the width
of the main web is used, a three-sheet product can be produced, by adjusting and

page_text: operating the delivery mechanism the same as in producing the two-sheet product
already described, or a six-sheet product may be produced by adjusting and operating
the mechanism the same as in producing the four-sheet product already described.
It is of course necessary that the pins 3 should be retracted to release the leading
ends of the sheets as soon as the folding blade 4 commences to act to fold the sheets
between the rolls 14. From this it results, that there is a time, after the sheets have
been released from the pins 3, and before they are fully nipped by the rolls 14, that
they are not under positive control, and during this interval, they are liable to slip
backward slightly upon the cylinder 46. To avoid this, the cylinder 46 is provided
with two or more stationary pins 11, which are so positioned as to impale the margins
of the sheets near their rear ends, and thus prevent the sheets from slipping backward
on the cylinder when released by the pins 3. The pins 11 are preferably pivotted in
the ends of studs 43 (see Figs. 18a and 184), which are screwed into the cylinder,
and arranged so that when not needed, they can be turned down into recesses 44
formed in the cylinder.
It is also found preferable, in practice, to provide the cylinder 45 with similar
pins 11 arranged to impale the rear ends of the sheets, so as to aid in holding
them snugly upon the cylinder.
The folder H may be modified considerably as to its form, without departing
from its essential features. For example, as shown in Figs. 7, 8, and 9, the internal
member of the folder, instead of being formed of a plate h, the edges which form
the internal guides 8, 9 may be formed of a bar 8 arranged obliquely to form the
internal guide S, around which one-half of the web passes, and a bar or roll 9 which
joins with the end of the bar 8, and is arranged to form the internal guide 9,
around which the other half of the web passes, this bar and roll being supportod
by rods 17 extending from the frame of the machine, the same as in the caso of
the plate. In the case shown, the end of the bar & forms a bearing for the journal
of the roll 9, and is so shaped as to correspond to the shape of the plate at the
corresponding point. In this case, also, the external member of the folder, instead
of being a plate, the edge 10 of which forms the external turner, consists of a bar 10,
arranged obliquely across the web in the same position occupied by the edgo 10 of
the plate g. This bar is supported by rods 16, the same as in the case of the
plate.
In the construction shown in Figs. 10 to 15, the internal and external members of
the folder are composed of plates h, y, the same as in the construction first described,
but in this case the folder is so arranged that the angle of the web, in passing over
the guiding edge 9, is considerably greater than in the first case, and this in some
cases will be an advantage. In this case, also, the folded web passes beneath instead
of above the roll 15. In this case, also, the plate is provided with a spring 12,
which lies within the fold of the web, and aids in creasing and defining the fold
line.
In some cases it will be found advantageous to provide tapes to aid in conducting
the web to and over the folder H. A convenient arrangement of tapes for this
purpose is also illustrated in Figs. 10 to 12. As shewn in these figures, the tapes 24
for this purpose pass around pullies 25 located above or near the roll 50, thence
forward with the web over the roll 19, thence downward along the inclined face of
the plate, and around pullies 26 located just below the edge 9, returning around
pullies 27. Inside tapes may also be provided, if in any case it should be desirable,
but such tapes will not usually be necessary. The roll 15 may be provided with a
companion roll, as indicated by dotted lines in Fig. 10, and these rolls may be driven
to effect the positive feed of the web.
The forms of the folder H which have been described are regarded as the
best for the purpose, but the invention is not limited to the employment of a
folder of either of these constructions, as a longitudinal folder of any approved form
may be employed without departing from the essential features of the invention.
Figs. 27, 28, and 29 illustrate an organization in which the folder H is of the

page_text: same form as the folder G, but is arranged to point in the opposite direction. In
this caso, one of the turning bars 47, and the roll 22, are extended so as to accommo-
date the full width of the web.
To produce the single sheet product shown in Fig. 25, both of the webs d aro led
around the bar 47, one web then passing around roll 21 to the folder G, and the
other around roll 22 to the folder H. The web which passes over the folder H is
then led between the fold-laying rolls 23 of the folder G, as shown in Fig. 27. In
other respects, the operation is the same as already described.
The cutting, folding, and associating cylinders 45, 46, instead of being arranged
parallel with the printing cylinders, may, if preferred, be arranged at right angles to
those cylinders. In such case, of course the web turning and associating mechanism
would have to be correspondingly modified.
In producing the products shown in Figs. 19, 21, and 22, it may be desired that
the sheets, or pairs of sheets, which are associated after being folded longitudinally,
should be pasted together along the line of the longitudinal folds. This, if desired,
can be readily done by providing a suitable pasting mechanism at any convenient
point, which will operate to apply a line of paste to one of the sheets, or pairs of
sheets, adjacent to the longitudinal fold line, so that when the two sheets, or pairs of
sheets, are associated upon the cylinder 46, they will be united by this line of paste.
Referring now more particularly to that part of the invention shown in Figs. 30
to 39, it will be seen that the internal guide which acts upon part of the web, lies
obliquely, while the other guide is arranged at right angles to the path of the web.
The internal member of part of the mechanism (see Figs. 30 to 39) consists of a
plate A a, which provides three internal guides 10 a, 11 a, 12 a. The guide 12 a consists
of the forward edge of the plate, which is curved so as to form a guiding edge, being
arranged at a right angle to the path of the web. The other two internal guides 10 a
11 a extend from the ends of the guide 12 a obliquely across the path of the web, and
are formed of the inclined edges of the plate A. a.
In the case shown, the base of the plate is attached to a bar 13 a having arms 14 a,
which are supported upon the shaft of a roll 15 a, arranged at the base of the plate.
The forward end of the plate is supported by means of one or more rods 1.6 a, which
are hinged at their forward ends to the under side of the plate, and extend rearward,
passing through bearings in blocks 17 a, which are adjustably supported upon a
transverse rod 18a. The bearing blocks 17 a are secured in position upon the
rod 18 by means of set screws, and the rods 16 a are secured in the bearings in the
blocks 17 by similar screws, as shown. By this means, the position and inclination
of the internal member of the folder can be adjusted to any degree of nicety. Three
guides 10 a,
11a,
12 a, forming the internal member of the folder, instead of being
formed by the edges of a plate, may of course consist of rods or bars arranged in
similar position with relation to each other.
The external turners of the folder consist of two bars 10 a, 20 a, which are arranged
obliquely across the path of the web, and in such position that their turning edges lie
adjacent to, and nearly, but not quite, intersect the points of union between the
internal guides 10 a, 12 a and 11 a, 12 a, respectively.--The guides 10 a, 11 a, 12 a, are
preferably slightly cut away or recessed at their points of union, as shown at 6ª (see
Fig. 34), so that they will be slightly removed from the fold lines just at the points
where the material is bent over the external turners. This, it has been found in
practice, will prevent the material from wrinkling, and facilitate the formation of
smooth folds. These external guides are pivotally supported at their upper ends upon
blocks 21 a, which are adjustably mounted upon a cross bar 29 of the framework of
the machine. By this means, the position of the external turners, and their angles
with relation to the web, can be varied within considerable limits, so as to effect the
necessary adjustment of the turners. The external turners are arranged in such
relation to the internal guides 10 a, 11 a, and to the direction taken by the web as it
leaves the guide 12 a, that the side portions of the web which pass over the guides 10 a,
11 a, being deflected inward and around the turners 19 a, 20 a, will be caused to travel

page_text: exactly the same distance as the central portion of the web which passes directly over
the guide 12 a, so that all portions of the web, considered widthwise, will be supported
and maintained at a uniform tension.
The folder, as thus far described, is so organized as to deliver the web folded to
three ply form, that is to say, with the sides or edges overlapping, so as to produce,
when combined with a printing machine, a folio or four-page product with an inset
supplement. To enable the folding to be accomplished in this form, it is necessary
that one side of the web should be deflected or folded over in advance of the other,
and to enable this to be done, the guides 10, 11", are arranged at different angles,
the guide 11 being more nearly parallel with the course of the web, so as to permit
the side of the web passing over that guide to be deflected inward more abruptly.
To aid in this more abrupt deflection, and to support and maintain the proper tension
upon the web between the guide 11" and the turner 20", there is provided a supplemental
internal guide 22ª, which is hinged to the under side of the plate A at the end of the
guide 12, and extends downward parallel with the central portion of the web after it
passes the guide 12ª, and is supported at its outer end by a rod 23, which extends
forward and downward from the underside of the plate A a.-This supplemental guide 22ª
is so arranged that the side portion of the web which passes over the guide 11ª,
being conducted around this guide 22ª, and thence around the turner 20º, will be
caused to travel exactly the same distance as the other side of the web which passes
over the guide 10ª, and around the turner 19ª, and will thus be held at the same tension.
The operation of the folder, as thus far described, is as follows:-In describing this
operation, it will be first assumed that it is desired to impart two parallel longitudinal
folds to the web, so as to produce a three-ply product. In this case, a web B equal
to the full capacity of the folder will be nsed. This web will led to and over the
roll 15 at the base of the plate A a, and will pass thence onto the plate, and be
deflected downward over the internal guides 10, 11ª 12%, as indicated in Fig. 30.-
To prevent the web from moving laterally upon the folder, and also to advance it
properly to and over the folder, tapes, as 9 a, may be employed, which tapes running
from any previous mechanism, may pass around the roll 15 and pulleys 8ª mounted
upon a shaft located above, or slightly in advance of the shaft of the roll 15.-Soine
of the tapes 94, instead of returning around the roll 15° and the pulleys 8", may pass
forward and return around pulleys located as indicated by dotted lines. In some
cases, the under tapes may be omitted.-The central portion 6, of the web will, after
passing over the guide or guiding edge 12ª, be led directly to suitable feed rolls,
as 24ª. The side portion ca, which passes around the guide or guiding
edge 11 will be deflected downward, and pass around the auxiliary internal
guide 22-After passing this guide, the side portion c will be still further
deflected, so as to pass around the external turner 20", which turner will operate
to lay that portion of the web over onto the central portion 6, thus effecting
a longitudinal fold, as indicated at eª Fig. 32.—The other side portion of the web
which passes around the guide or guiding edge 10ª, will be deflected downward and
inward, and pass directly around the turner 19 a, so as to be laid over onto the
portion c, thus folding the web longitudinally, as indicated at f, Fig. 32, thereby
producing a three-ply product, as shown. The web thus folded twice longitudinally,
and reduced to three-ply form, passes between feed rolls 24ª, and may then be
operated upon by any suitable transverse cutting, or cutting and folding, or cutting,
folding, and associating mechanisms, as indicated by the cylinders 25, 26, Fig. 31.
The folder thus constructed and operated is especially adapted for making the
longitudinal folds necessary to produce a folio or four-page paper with an inset
supplement composed of a half sheet or two pages. When this product is to be
produced, the web will preferably be slit by a slitter, as 27, arranged at any suitable
point, as shown by dotted lines Fig. 31, so that the inset portion will, in the
delivered product, be detached at its outer edge from the portion 6.-Or if preferred,
the slitter may be arranged to slit the web on the fold line f, in which case the
supplement sheet will be on the outside instead of inset.

page_text: If, instead of imparting two longitudinal folds to the web, it should be desired to
impart only one longitudinal fold," a web of only two-thirds the full width will be
used, and this web will be led to the folder the same as before. One side portion
of the web, which in this case will correspond to the central portion be, will be led
over the guide or guiding edge 12, while the other side portion, corresponding to
the portion d, will be deflected over the guide or guiding edge 10ª, and led around
the turner 19, so as to be laid over onto the portion ", as illustrated in Figs. 35
and 36. In this case, the guide or guiding edge 11, the supplemental guido 22",
and the turner 20, will be idle. If it is not desired to capacitate the folder to impart
the two longitudinal folds, then of course the parts which are idle in the case just
described niny be entirely omitted, and with such parts omitted, the folder will embody
the invention in its simplest form.
As thus far described and illustrated, the invention is embodied in a folder which is
capacitated to deliver the product in suitable form for a folio or four page product,
or for such product with an inset supplement. It may, however, in some cases, be
desirable to construct the folder in such form, that the web, when folded twice
longitudinally, will be delivered in condition to form duplicate side by side streams of
folio products.
An arrangement of the apparatus suitable for accomplishing this purpose is
illustrated in Figs. 37 and 38. In this case, the guides or guiding edges 10ª, 11ª,
are set at the saine angle, so that the side portions c d of the web, instead of being
overlapped, will be folded over onto the central portion be, so that their edges will
meet, or substantially meet, at the centre of the portion 6. By then slitting the
web centrally as indicated by the dotted line, two side by side streams of folio
products can be produced.
With the folder thus arranged, it may sometimes be desirable to produce the
product illustrated in Figs. 30 to 33, that is to say, the folio product with the inset
supplement.
",
is
To capacitate the machine to produce this result, the plate A a, or the guide 12
made in parts, the side portions a being adjustable to and from cach other, and the
central portion ga removable; the turner 19a is made correspondingly adjustable, and the
guide or guiding edge 11ª is made capable of being adjusted to different angles with
relation to the web.
When it is desired to deliver the web folded to the form shown in Figs. 30 to 33,
the central portion ga will be removed; the two parts a of the plate A a, or the
guides 10 11 a, will be adjusted together, and secured in that position; the guide or
guiding edge 11 a will be adjusted to a position to correspond with the guide or guiding
odge 11" in Figs. 31 to 34, and the turner 20 a adjusted to a corresponding position,
all as shown in Fig. 38. A web of three-fourths full width will be used, and tho
operation will be the same as first described. When however it is desired to deliver
the web in condition to produce side by side streams of folio products, the two parts
of the plate A a will be separated, for which purpose extra bolt holes 2 are provided
in the bar 13 to permit one part of the plate to be moved outward, and the supple-
mental piece will be inserted between the two parts of the plate A a, to continue the
guide or guiding 12 a. The turner 20 a will be shifted outward on the bar 29 a to a
corresponding position; the guide or guiding edge 11 a will be adjusted to the same
angle with relation to the web as the guide or guiding edge 10, and the auxiliary
guide 22 will be detached from the plate A a at its inner end, and said guide and its
supporting rod will he swung to one side so as to be out of the way of the web, all
as indicated in Fig. 37.-A full width web will be used, and the two sides portions ca da
of the web passing over the guides or guiding edges 10 a, 11 a, will be deflected inward
by the turners 19 a, 20 a, so that their edges will meet, or substantially meet, at the
middle of the portion . By then slitting the web longitudinally at its centre,
as indicated by the dotted line, two side by side streams of folio products can be
produced.
To permit of the adjustment of the turner 20 a, the bar 29 a may be provided with
B

page_text: extra bolt holes to receive the bolts which attach the block 21 a. To provide for the
casy adjustment of the guide or guiding edge 11, the guide is formed on a small
triangular portion 28 a of the plate A a, which is connected to the main part of the
plate by curved slotted arms 30°, through which pass bolts 3. By this means, the
guide 11 a can readily be adjusted to any desired angle. The end of the guide 22 a is
secured to the plate a by means of a bolt 4a, which passes through an eye in the
end of the guide. By removing the bolt 4, the guide can readily be disconnected,
so as to be swung to one side, as shown in Fig. 37. The two parts a of the plate A a
are connected at their forward ends by tic plates 7", which fit into each other, as
shown in Fig. 38, and these plates also provide a convenient means for securing the
central portion g in position, as shown in Fig. 37.
