Abstract

Abstract Apparatus for treating cigarettes in which a blind conduit is formed in the lighting extremity of the cigarette and terminates in an air-tight wall, placed in position at the bottom of the conduit so formed by punching means, the apparatus comprising essentially a ring provided with a plurality of radial grooves, each groove intended to house a cigarette, a plurality of successive conduit-punching devices and devices for introducing the air-tight bottom walls, and also provided with tubes and ejector devices on the outside periphery of said ring, while on the inside periphery of said ring is provided an evacuation passage for the cigarettes ejected towards an evacuation ramp, and above said ring a plurality of narrow, vertically elongated hoppers supply at least some of said grooves, said ring being rotated so as to bring a groove alternately in front of a punching and introducing device and an ejector device or viceversa.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 214 words
Apparatus for producing blind conduits in cigarettes, comprising a substantially horizontally disposed ring having a plurality of radial grooves in its upper surface for the reception of cigarettes, a plurality of successive conduitpunching devices on the outer periphery of said ring for punching blind conduits in the tobacco of cigarettes carried in said grooves, means on the outer periphery of the ring for introducing airtight disks into the bottoms of said blind conduits, evacuation means for removing cigarettes disposed on the inside of said ring, ejector means for moving cigarettes from said grooves to said evacuation means, means for rotating said ring so as to bring the groove initially facing said punching and introducing means in front of said ejector means, a plurality of hoppers disposed above said ring to supply cigarettes to said grooves, means defining an annular passage above said hoppers, a mobile distributor movable above said annular passage to supply cigarettes to said passage, loading apparatus for said mobile distributor comprising a member pivotable between lower and inverted upper horizontal positions, a conveyor belt for cigarettes terminating substantially in said horizontal position, and receptacle means adapted to receive cigarettes from said loading apparatus and disposed above said mobile distributor, said receptacle means having lower closure shutters for releasably retaining cigarettes therein.
Claim 2
Dependent Claim 214 words
Apparatus for producing blind conduits in cigarettes, comprising a substantially horizontally disposed ring having a plurality of radial grooves in its upper surface for the reception of cigarettes, a plurality of successive conduitpunching devices on the outer periphery of said ring for punching blind conduits in the tobacco of cigarettes carried in said grooves, means on the outer periphery of the ring for introducing airtight disks into the bottoms of said blind conduits, evacuation means for removing cigarettes disposed on the inside of said ring, ejector means for moving cigarettes from said grooves to said evacuation means, means for rotating said ring so as to bring the groove initially facing said punching and introducing means in front of said ejector means, a plurality of hoppers disposed above said ring to supply cigarettes to said grooves, means defining an annular passage above said hoppers, a mobile distributor movable above said annular passage to supply cigarettes to said passage, loading apparatus for said mobile distributor comprising a member pivotable between lower and inverted upper horizontal positions, a conveyor belt for cigarettes terminating substantially in said horizontal position, and receptacle means adapted to receive cigarettes from said loading apparatus and disposed above said mobile distributor, said receptacle means having lower closure shutters for releasably retaining cigarettes therein.
Claim 3
Dependent Claim 67 words
Apparatus as claimed in claim 1, said hoppers having articulated flaps adapted to dispense one cigarette into each groove, said flaps being mounted on shafts which are coupled with each other by levers and to a main lever, and a vertical rod actuating said main lever and a cam carried by said ring and adapted to engage the lower end of said rod for actuating the same.
Claim 4
Dependent Claim 24 words
Apparatus as claimed in claim 1, and a plurality of devices disposed radially outwardly of said ring for introducing tubes into said blind conduits.

Dependent Claim 26 words
Apparatus as claimed in claim 1, and means associated with each of said punching devices for holding a cigarette in one of said grooves during punching.
Claim 6
Dependent Claim 38 words
Apparatus as claimed in claim 1, said means for introducing an airtight disk comprising a cutting-out punch for cutting out said disks and means to supply a band of the material of said disks to said cutting-out punch.
Claim 7
Dependent Claim 29 words
Apparatus as claimed in claim 1, and slides on which said punching devices and disk-introducing means are mounted and means for reciprocating said disk-introducing means radially of said ring.
Claim 8
Dependent Claim 22 words
Apparatus as claimed in claim 6, and means mounting said slides for rotation about axes constituted by their paths of radial reciprocation.
