In cigar rolling apparatus of the apron-rolling
type and in which the portion of tobacco allotted
for making the ñller is thrust into a trough on
the rolling table o-n which the rolling apron is
-5 located, a roller extending over .the table co
operates with the rolling apron for the purpose of
forming the bunch. This roller is mounted on a

suitably pivotally mounted lever support. In the
Figs. 6-11 are `detailed views.
preparation of a bunch the tobacco is provided
with a wrapper. This must therefore be placed
on the rolling apron, which is generally done by
hand. As the wrapper must first of all be pre
pared (spread out and smoothed) before it can be
applied, there is a relatively short time available
The table AI for the wrapper consists of >a plate
" for this operation which must be performed by
one and the same person, and consequently the
attendant does not allow the machine to run
continuously, but stops it whenever a wrapper has
to be applied and sets it in motion again when
the operation is completed. With large plants
of complicated construction, the wrapper-apply
ing operation can be performed by purely
mechanical means, for instance by means of a
suction head which seizes the wrapper which is
cut out on a table, likewise mechanically, and
‘ then is guided in such manner that it forwards
the wrapper to the depositing position.
This,
u
provided with sieve-like openings beneath which
a suction head housing 2 is ,mounted The
suction head .housing is connected by means of
a pipe 3 with »a fan 4 which is driven by a belt. 5
and a motor 6. The suction head housing is
carried by a projecting arm G’ .attached to the
machine frame G. The table I, the special form
of which is shown in Fig. 3, is provided with four
recesses I’ in which the hereinafter described
gripping members engage. The gripping mem
bers consist of a bar l, which is carried by two
arms 8.
The latter are carried on levers I0
mounted on the machine frame at 9.
On the
arms 8, which are mounted on the upper end
of the lever I0, there is Yprovided an axle Il on
which a support I 2 is rigidly> mounted for movable
to-ng jaws I3 which consist of two plates attached ’
«to the support I2, each of which plates has two l
struction and above all very expensive, because
30 the control of the suction head is not simple and
lu'gs I3’ which project in the corresponding op
erative position into the range of the recesses I’
of the table I.v »On the axle II there is ñrmly
at the same time a means of control of the
mounted a control lever I4, the end of which is
suction air current itself must be provided.
The object of the present invention is `to
apply the wrapper by purely mechanical means
while using machines of simple construction, i. e.
small cigar-making machines.
This end is attained by providing the rolling

with a plate Il mounted on the machine frame
at I6, which plate, when in its neutral position,
rests on a pin .I 8 provided on the machine frame. _
of the bunch roller, on the forward movement
of the support, seizes the wrapper and on its
When the lever I0 swings to the right as in
dicated in Figs. 1 and 6, the roller .comes into con
tact with the plate I`1. This causes the lever I4
and the jaws I3 connected therewith to swing
out against the tension of a spring I9 in such 40
manner that the mouth of the tongs opens.
When the lever I0 has arrived in its extremel
backward movement, places it over the trough
right-hand position in which, as shown particu
apparatus with a special table on which the
wrapper is placed in such manner that a con
40 trolled gripping member arranged on the support
which receives the iiller tobacco.
In this manner the support of the bunch roller
45
itself is utilized for applying the wrapper, so that
by means of this already available swinging mem
er the wrapper can be applied mechanically
without other intermediate members being pro
50 vided, namely with ease, at the right moment
and at the right place.
The invention is illustrated in the annexed
drawings, in which:
Fig. 1 is a vertical longitudinal section through
55 the apparatus.
larly in Fig. 4, the front edge o-f the wrapper U
:comes into position between the opened mouth
of the tongs, the roller I5 on the lever 'I4 comes
into the range of a recess Il’ provided in the
plate I1. The roller on the lever I4 is thereby
released and is able to swing into the position
indicated in full lines in Fig. 7. At the same time
the wrapper is held firmly, under the action of the
spring I9, between the jaws I3’ and 'l of the
tongs. When the lever I0 swings back into the
position indicated in Fig. 2, the wrapper is car
ried along and withdrawn on to the depositing A.55

15 one hand by a jaw 25 which is carried by a tu
loop formed behind the roller 5I. Fig. 11 shows 15
bular member 26 provided with a collar 26’. Into the precise moment in the operation when the
the tubular member 26, which is adapted to be
displaced axially in a housing 21 attached to
the machine frame G, there is passed a rod 28.
20 A sleeve 29 is pivotally mounted on the rod 28,
and with this a lever 38, which is pivotally
mounted on the machine frame at 3l, engages.
The lever 30 is provided with a roller 32 which
comes into contact with a cam disc 33.
The
25 camdisc is mounted on a shaft 34 to which a
soon as thev bunch formed in this manner has
reached the end of the rolling table, it is de
posited in known manner in a receiving trough
or the like. These receiving troughs may be at
spur wheel 35 is also attached. ` ‘I'he spur wheel
tached to a conveyor chain which feeds the bunch
35 engages with a corresponding spur wheel 36
which is mounted on the driving shaft 31 of the
forward to the place where it receives further
treatment, for instance to the rolling device in
which the wrapper is applied. In its extreme
right-hand position the roller I5 of the movable
tong jaws comes into contact with the plate I1
so that when it swings into its extreme outermost
position, >the tongs `with open jaws come into
the range of the depositing table I whereupon
machine, this shaft 31 being connected by means
30 of a belt pulley 38 and a driving belt 39, with
the electro-motor 6. On the driving shaft 31 is
mounted a crank disc 40, the crank pin 4I of
which engages in a cam slot I8' of the lever
I0.
'I'he other side of the trough is formed
35 by a plate 42, which is pivotally mounted on an
axle 43, which is provided on the horizontal part
of the jaw 25. An arm 42’ of the plate 42 pro
trudes into a recess in the jaw 25 and is pressed
by a spring 44 against the head 28’ of the rod 23.
40
filler P which is for the greater part covered by
the wrapper, is withdrawn from -the trough,
which is done by a slight movement of the plate
42. By this means the corresponding end of the 20
wrapper is placed ñrmly about the filler P. As
When the tongs 1, I3 have arrived in the posi
tion indicated in Fig. 8, the rolling table trough
25, 42 is brought into the position indicated in
Fig. 8.
This is effected by means of the lever
30, in that, between the upper adjusting nuts 29’
45 of the sleeve 29 and the collar 26’ of the tu
bular member 26, a spring 45 is inserted. The
tubular member 26 and the jaws 25 connected
therewith are therefore upwardly displaced by
the lever 30 without the rod 28 being displaced
50 in the tubular member 26 until the collar 26'
rests against the bottom of the housing 21. In
this position a spring-controlled stop 41 which is
provided in a pressure chamber 48 is pressed
back in such manner that it is placed flexibly on,
55 and thereby firmly holds, the wrapper U lo
cated on the rolling apron 20. But at the same
time a projection I4’ provided on the lever I4
strikes against a stop consisting of an adjusting
screw 49 whereby the mouth of the tongs is
60 opened so that the wrapper now lies freely on
the rolling apron 28, held only by the flexible
pressure member 41. Now while the plunger 59
thrusts the compressed tobacco P from the pres
sure chamber 48, the sleeve 29 is raised owing
65
to its further movement into the position indi
cated in Fig. 9. As the tubular member 26 and
the jaws 25 have attained their highest posi
tion the further movement of the lever 30 is
70 utilized, while overcoming the spring 45, to dis
place the rod 28 upwardly in the tubular mem
ber 26. This causes the plate 42 to be moved
outwards so that the ñller can be introduced
without difliculty. During this operation, the
75 spring-controlled pressure member 41 holds the
the operation is repeated.
Having thus described the nature of the said
invention and the best means I know of carry
ing the same into practical effect, I claimt
