COMPLETE SPECIFICATION
Improved Machine for Winding Tobacco in Tobacco Leaves We, AaENCO
AKTIEBOLAG, a Swedish Joint-Stock Company, of 20, Alstrdmergatan,
Stockholm, Sweden, do hereby declare the invention, for which we pray
that a patent may be granted to us, and the method by which it is to
be performed, to be particularly described in and by the following
statement:-
This invention relates to machines having a rolling table and a
rolling apron for winding tobacco in tobacco leaves, for example in
the manufacture of tobacco products having configurations like
cigarettes.
In known such machines, which are similar to cigar bunch making
machines, the tobacco leaf is ordinarily pasted to produce a seam, and
paste is likely to adhere to the rolling apron so that the wound
article might stick thereto and be retracted by the rolling apron when
moving back into its initial position, or said article - will adhere
only slightly to said apron so that it will drop from same in an
irregular manner and be positioned incorrectly relative to means
provided for cutting its ends.
It is an object of the present invention to remove this drawback.
2. Accordingly, the invention provides a machine adapted for winding
tobacco in tobacco leaves, comprising a rolling table and a rolling
apron arranged for delivering the wound product directly to a support
located adjacent an edge of the rolling table, characterized in that
the support has a nozzle which is connected to suction means adapted
to retain the product on the support when the rolling apron is
retracted for the support.
An embodiment of the machine according to the invention is hereinafter
described, by way of example, with reference to the accompanying
drawings, in which: [Price 3/6] Fig. 1 is a vertical sectional view of
the front portion of the machine, Fig. 2 is a front elevational view
of said machine, and Fig. 3 is a vertical sectional view of 50 certain
features of the machine in other operative positions than in Fig. 1.
Referring to the drawings, the machine has a rolling apron 2 placed on
a perforated rolling table 1 and operated by a55 bunch roller 3 which,
in the same manner as in an ordinary cigar bunch machine, operates the
apron 2 to move forwardly and rearwardly over the rolling table 1 to
form a tobacco article 4 by winding 60 filler tobacco in a tobacco
leaf placed on the apron whereafter the roller 3 is retracted and the
apron 2 is moved back by means (not shown). The roller 3 is mounted on
a forked lever 5 which is 65 secured to a shaft 7 rotatably journalled
in the machine frame 6. The lever 5 is reciprocated by means of a cam
disc 13 secured to a rotatable shaft 14.
At the front edge of the rolling table 1, 70 the wound article 4 is
delivered by the apron 2 directly to a receiver 15, which consists of
a support located adjacent the edge and formed as a suction nozzle
conneeted to a suction conduit 16 which in75 turn is connected to any
suitable suction source, conveniently the one to which an interior
chamber of the perforated rolling table 1 is connected, so as to form
suction means which is adapted to retain the 8( article 4 on the
receiver 15 when the apron 2 is retracted from the receiver. Fig. 1
shows the position of the tobacco article 4 just before the rolling
apron 2 is about to project beyond the front edge of the 85 rolling
table 1 and be tensioned in Fig.
3 the article 4 has been sucke&z by the receiver 15 down from the
tensioned rolling apron. The mouth of the suction nozzle extends
lengthwise of the front 90 780,119 edge of the rolling table.
From the receiver 15 the tobacco article 4 is elevated by a carrier 17
consisting of a pair of legs and driven in well known manner by the
cam disc 13 actuating the lever 5. Said carrier 17 moves the article 4
against two stationary scissor legs 18 so that ifs ends will be cut
off, whereafter the article is moved further and delivered by the
carrier 17 to the second receiver 19 from which it can be transmitted
for further treatment.
