band, paper, and tobacco are fed, not only with the requisite forming, pasting, and
compressing rollers or discs, but also with a supplemental half tube or cover
for the bottom half tube which shall immediately follow the compressing-wheel
and hold the band and pasted edges of the cigarette rod closely in place, giving
time for the paste to set before the endless band reaches the open edged portion
of the tube and is allowed to resume an upright position in so far as one edge is
concerned.

Improvements in Apparatus for the Manufacture of Cigarettes.
I, BERNHARD BARON, of 4, 5, 6, St. James' Place, Aldgate, London, Manu-
facturer and Inventor, do hereby declare the nature of this invention and in what
[Price 8d.]

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
In Specification to Letters Patent No. 14,881 of 1895 is described an apparatus for
the manufacture of cigarettes, the tobacco being first moulded to a rod-like form
and then passed on to an endless travelling tape upon which rests the paper form-
ing the cigarette wrapper. As such tape, paper, and tobacco travels forward the
upturned edge of the paper is gummed or pasted and it together with the endless
tape is then pressed down upon the other edge of the paper by a presser-wheel,
and the two edges being secured the endless tape is permitted to rise and resume
its upturned position.
In practice though this machine works very well it is found that it necessitates
the use of a considerable lap for the paper and occasionally difficulty is experi-
enced in getting the edges to adhere owing to the pressure being taken off and the
endless tape edge permitted to rise as soon as it passes the compressing roll. It
is the object of this invention to remedy this somewhat slight defect, and to
enable but a very slight lap of paper to be taken. To this end the invention
consists in providing the half tulie or trough, through which the tape or endless
band, paper, and tobacco are fed, not only with the requisite forming, pasting, and
compressing rollers or discs, but also with a supplemental half tube or cover
block which shall immediately follow the folding or compressing wheel and hold
the tape and pasted edges of the cigarette rod closely in place, giving time for the
paste to set before the endless tape reaches the open edged portion of the tube
and is allowed to resume an upright position in so far as one edge is concerned.
In the accompanying drawing I have illustrated the arrangement forming my
present invention as applied the cigarette machine illustrated and described in the
specification before referred to, the same reference figures and letters being
employed in the present drawing where the parts are similar to those in the
specification referred to:-
In the drawing
Fig. 1 is a plan of the wrapping trough shewing the folding discs and pasting
wheel in dotted lines.
Fig. 2, is a side elevation of the trough.
Figs. 3 to 6, are cross sections of the trough upon the lines 9 to 12 respectively,
Figs. 1 and 2 looking in the direction of the arrow.
Fig. 7 is a cross section on line 14 Figs. 1 and 2, and,
Fig. 8 is a cross section on line 13, Figs. 1 and 2.
The endless tape 40 and paper strip & enter the trough J at the left hand end
together with the rod of tobacco previously formed, the latter passing if desired
under a blade 113 (see Fig. 3), should the tobacco be very elastic. One standing
edge of the paper together with the tape is then brought against the curved 4
edge of a folding disc 108 which turns down that side of the paper onto the
tobacco rod (see Fig. 4) after which the paster wheel 100 applies a line of paste
to the inner face of the opposite standing edge of the paper (see Fig. 5). The
latter standing edge is then bent over onto the infolded side and pressed against
the same to cement the two together by a curved edged folding disc 110 (see 4
Fig. 6) the edge of the tape previously turned down having escaped momentarily
for this purpose by rising up in the gap in which the disc 110 is seated the
overhanging block being cut away for this purpose on a sloping flared line, after
which with the continued movement of the rod the tape is again bent down by
the edge of the block 121 which forms a complete cover to the trough so that 5
the rod, pasted wrapper and tape pass through (see Fig. 7) until they arrive at the
overhanging block 121 having an under curved face (see Fig. 8) from which one
edge of the tape may escape after which the sealed tube of tobacco passes on to
the cutter. It is the part 121 which I have introduced to follow the folding or
compressing wheel as this part with its curved under face forms with the trough 5
a complete tube in which the paste is able to set and wherein the sealed tube

page_text: receives the full benefit of the extra compression on its lapped and pasted parts,
of the encircling tape which it does not receive in the overhanging block 121ª as
such tape immediately escapes therefrom. The block is held on the trough J by
some suitable means such as by dowel pins 121b and a thumb nut 121 working
on a screwed rod 121 pivoted on a pin 121° embedded or held in the solid portion
of the trough J. By turning the nut in one direction the rod 121 may be thrown
over and the block 121* released, and by tightening it on the block the latter is
firmly held. In this way the block is readily removed for examination cleaning
and the like.
"
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
1. In apparatus for the manufacture of cigarettes the employment of a com-
plete tube portion immediately following the last folding wheel whereby the
pasted paper and carrying tape are all held together in a closed condition on the
tobacco rod, substantially as and for the purpose specified.
2. In apparatus for the manufacture of cigarettes the combination with the
trough J and pasting and folding wheels of the closed cover or block 121*
immediately following the last folding wheel, substantially as and for the purpose
described.
