page_text: I EDGAR KONIG of Kloster Oberzelt, Würzburg in the Empire of Germany, 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:-
My Invention relates to paper folding machines and it consists in arrangements
of mechanism bereinafter described whereby the same machine is enabled to effect
the longitudinal and transverse folding of paper having the full width of the sheet
and is also enabled to divide the paper longitudinally when required folding, the
two half width sheets transversely at the same time and delivering them separately
on opposite sides of the machine.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1 and 2 of the accompanying drawings represent front elevations of so
much of the working parts of the machine as is necessary to explain my Invention.
In Figure 1 a double acting guide or turning device m with which the apparatus is
provided as hereinafter described is represented in its lowest position or as being
out of action this being the position which it occupies when the machine is used
for folding the undivided paper longitudinally and transversely. Figure 2 shows
the guide m elevated into the position which it occupies when the two halves of
the paper which is cut or divided longitudinally by a cutter x are caused to travel
in opposite directions being carried away by the tapes and delivered to a folding
cylinder V and folding rollers p p whereby they are folded transversely.
Figure 3 represents a side elevation of the apparatus a side roller n³ figures 1
and being removed and the parts being in the position corresponding with
figure 2. Figure 4 represents a detail hereinafter referred to.
The paper is drawn into the apparatus by a pair of rollers 6 and the lower roller
of this pair is provided with a groove which receives the cutting edge of a rotary
or disc cutter x when the paper is to be divided longitudinally. This cutting
device can be thrown out of action when required by swinging back the disc x and
in this case the paper is folded longitudinally upon a conical longitudinal folder S.
The folding rollers d of this folder are carried on supports c capable of sliding upon

guides on the side frames q and of being fixed in any desired position by means of
The adjustment of these rollers is most conveniently effected by means
of crank handles attached to shafts provided with pinions u gearing with rack
teeth figure 3 on the undersides of the supports c. By simply turning the
handles the rollers d can be readily and accurately adjusted at any required 5
distance apart.
The turning device m hereinbefore referred to is made in two parts m and n.
The part n is capable of turning or swinging on an axis or shaft and can be fixed
in position by a screw and the part m is capable of sliding vertically on guides g.
The turner n turns the sheets to the right and is fixed on a shaft o (see detail 1
figure 4) carrying a loose tape roller n³ provided with grooves for the reception of
the fingers n of the turner n which is made wholly of metal. The tape roller n³
carries the tapes by which the paper is carried down to the transverse folding
rollers. The turner n with its fingers n¹ can be readily fixed in either of the
positions which it is required to occupy as hereinafter explained by means of a set 1
screw o¹ acting on the shaft o..
The turner m is provided with sliding pieces at the sides working on guides g so
as to allow the turner to be elevated or brought into action or to be lowered and
thrown out of action as required. This turner likewise consists of a metal bar
carrying two series of turning fingers m' m². Both series extend upwards for an
equal distance but the fingers m¹ do not extend downwards beyond the level of
the axis of the roller d when the turner is in its highest position and where they
meet the ends of the fingers n² herein before described. The fingers m³ extend
downwards for a sufficient distance to enable them to enter grooves in a roller v
turning on centres attached to the body of the turner m so as to move with the
latter. The left hand set of carrying tapes are passed over this roller and act in a
similar manner to those on the right hand side.
Tootbed racks are provided at each side of the turner m and gear with pinions u
on shafts provided with crank handles whereby the turner can be adjusted
vertically in a similar manner to the supports c.
P
The tapes on the right and left hand side of the machine are arranged at equal
distances from the central line and the upper tapes proceeding round the folding
rollers d pass over guide rollers ff1 to the upper transverse folding rollers and
thence are led back to the rollers d. The under tapes proceed to the right and
left from the rollers n² and v passing to the right from n³ over the guide rollers f¹
and and thence over guide rollers i back to roller n². The left hand tapes
pass from roller v over the rollers fk and ii back to the roller v. The left-hand
guide roller k is capable of moving vertically so as to maintain the tension of the
tapes which would otherwise become slackened when the roller is lowered along
with the turner m.
The action of the mechanism is as follows:-
ย
In order to change from folding entire or full width sheets (which is accomplished
in the usual manner the entire sheet being folded longitudinally by the action of
the folder S and rollers d and the folded sheet being guided to the right by the
fingers n¹ of the turner n which engage in grooves in the left hand folding roller d
figure 1 and conveyed by the right hand tapes to the transverse folding rollers p p¹
on the right hand side of the machine) to folding two half sheets simultaneously
the positions of the parts are altered as follows:-The disc cutter x is swung out
of action, the screws securing the supports c are loosened and by turning the
handles the supports are moved back in opposite directions so as to separate the
longitudinally folding rollers d and cause them to occupy the position illustrated
in Figure 2. The screw o¹ which secures the turner is loosened and the turner n
is swung to the right until the upper extremities of the fingers assume the position
indicated by the dotted lines in Figure 1. A space is thus made for bringing up
the turning device m which is then elevated by means of the crank z and pinion u
until the upper extremities of the guide fingers m¹ m² meet the folder S which
is provided with recesses for the reception of the said extremities to the extent of

page_text: about 3 m, m, so that they merge into the said folder and present no projection or
obstacle that would be liable to catch the edge of the paper. The turner n is then
swung back (or to the left) until the fingers n' occupy the position indicated in
figure 2. When in this position they bear against the part m and form direct
continuations of the fingers m¹ on the right hand side of the said part m.
The set
screws being tightened up the apparatus is then ready for working. The sheet
being cut or divided longitudinally by the cutter x the two half sheets instead of
being folded together by the rollers d d are turned off by the fingers m¹ m² of the
turner m and are directed to the right and left hand tapes at the lower part of the
apparatus. These tapes deliver the two half sheets simultaneously at both sides of
the folding cylinder V in such a manner that they are seized and folded transversely
exactly in half or across the middle by the transversely folding blades e acting in
combination with the rollers p p¹.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
In a paper folding machine the arrangement of the cutter x acting at the middle
of the feed roller b of a conical folder and capable of being swung into or out of
action as required in combination with the arrangement of the sheet guiding or
turning devices m m² m² the arrangement of the pair of folding rollers d capable of
being set close together or at a distance apart as required and the lower tape
carriers as hereinbefore set forth whereby one and the same machine is enabled not
only to fold whole sheets by means of the folding apparatus and to deliver the
same in one direction but also to draw half sheets through the longitudinal folder
unfolded and to forward them in opposite directions in such a manner as to deliver
the said half sheets after folding them separately in a transverse direction sub-
stantially as herein before described and illustrated by the accompanying drawings.
