- the second portion presents a cross sectional profile that diminishes gradually along the feed direction of the continuous bundle, so as to avoid interference with the garniture device and allow the paper strip to wrap progressively around the bundle.
- the forwardmost end of the second portion lies below and in close proximity to the entry point of folding means by which the two longitudinal edges of the strip of paper material are overlapped, one edge having being gummed previously, and secured to form a plugwrap around the rod.
- feed and transfer devices of the type in question are costly in the extreme by reason both of the complex manufacturing steps involved in their production, and of the materials utilized, which must afford high resistance to wear and mechanical stresses.
- certain devices of prior art design are equipped with a first and second portion embodied as two distinct pieces, so that a failure of the second portion will not necessarily signify replacement of the entire connecting element.
- the feed system is set in motion until a given length of bundled filter material has emerged from the shaping means.
- the first inlet portion of the connecting element is then disassembled, having released the fastening means by which it is held in place.
- the leading end of the bundle is inserted a suitable distance into the first portion, by hand, whereupon the first portion can be returned to its operating position between the shaping means and the second portion of the connecting element.

Abstract
Description
- The present invention relates to a machine for manufacturing filters applicable to tobacco products, and in particular to cigarettes. Such a machine is disclosed e.g. in
US-A-3 645 175 . - Conventionally, the manufacture of cigarette filters involves processing a continuous stream of filter material, such as cellulose acetate, drawn from a compacted bale.
- The stream is fed along a set path through processing stations, where it is first stretched lengthwise and crosswise and then impregnated with chemical additives, typically triacetin.
- At a further station, the filter material is gathered by shaping means into a continuous rope, or bundle, of cylindrical appearance.
- In prior art filter makers, the shaping means appear as a funnel-like duct through which the continuous stream is directed, with the result that cross sectional area of the stream is reduced by degrees, and the stream transformed ultimately into a rope or bundle of predetermined diameter.
- Located downstream of the funnel-like duct is a connecting element that serves to transfer and guide the stream into a wrapping station where the continuous bundle, advancing along a predetermined direction, is enveloped gradually in a continuous strip of paper material and fashioned thus into a continuous filter rod that will then be divided up into single filter plugs by a rotary cutter device.
- The wrapping station comprises a transport belt looped around two return rollers, of which the top branch runs slidably along a tongue affording a longitudinal groove; the groove presents a cross section varying continuously between the infeed end and the outfeed end of the tongue, considered along the feed direction of the bundle, and appearing substantially cylindrical at the outfeed end, with a radius of curvature substantially equal to the radius of a filter.
- The transport belt sliding in the aforementioned groove constitutes a garniture tape by which the strip of paper is forced to wrap around the bundle, thereby forming the aforementioned continuous filter rod.
- The connecting element is positioned above the top branch of the transport belt and comprises a first tubular portion of funnel-like appearance, joined to the means by which the filter material is shaped into a bundle, also a second portion of trough-like appearance with a concave face directed toward the selfsame top branch of the belt.
- The second portion presents a cross sectional profile that diminishes gradually along the feed direction of the continuous bundle, so as to avoid interference with the garniture device and allow the paper strip to wrap progressively around the bundle.
- The forwardmost end of the second portion lies below and in close proximity to the entry point of folding means by which the two longitudinal edges of the strip of paper material are overlapped, one edge having being gummed previously, and secured to form a plugwrap around the rod.
- The forward motion of the continuous bundle and the relative strip of paper on the transport belt is assisted by the compressive force applied to the bundle through the second portion of the connecting element.
- As machine parts, feed and transfer devices of the type in question are costly in the extreme by reason both of the complex manufacturing steps involved in their production, and of the materials utilized, which must afford high resistance to wear and mechanical stresses.
- It has been found in practice that where a jam or obstruction impedes the sliding motion of the looped belt, the stresses in question are such as to degrade the integrity of the second portion of the connecting element, being structurally the more fragile, with the result that the entire connecting element needs to be replaced.
- To limit the costs generated by this drawback, certain devices of prior art design are equipped with a first and second portion embodied as two distinct pieces, so that a failure of the second portion will not necessarily signify replacement of the entire connecting element.
- Conventionally, to set up the machine ready for operation, the feed system is set in motion until a given length of bundled filter material has emerged from the shaping means.
- The first inlet portion of the connecting element is then disassembled, having released the fastening means by which it is held in place.
- Next, the leading end of the bundle is inserted a suitable distance into the first portion, by hand, whereupon the first portion can be returned to its operating position between the shaping means and the second portion of the connecting element.
- Self-evidently, such a procedure is laborious and time-consuming for operators, as well as carrying the risk of breakages should the dismantled portion suffer accidental impact or fall.
- Further drawbacks affecting machines of prior art design include the possibility that the bundle of filter material can become jammed internally of the connecting element.
- Given the particular structure of such machines, in effect, the task of restoring normal operation is rendered notably complex due to the difficulty experienced by the operator in accessing the area affected by the jam.
- Likewise in this instance, the first portion of the connecting element needs to be disassembled.
- The object of the present invention is to provide a filter maker unaffected by the various drawbacks associated with the prior art as described above.
- The stated object is realized according to the invention in a machine for manufacturing filters applicable to tobacco products, as characterized in one or more of the appended claims.

- The machine 1 comprises a
magazine 2 containing filter material, from which this same material is drawn off and formed into acontinuous stream 3 by means not illustrated in the drawings. - The
stream 3 is directed along a feed path P, following a direction F arrowed infigure 1 , toward longitudinal and transverse stretching means shown schematically as two pairs of contrarotating rollers denoted 4 and 5 respectively. - Downstream of the stretching means 4 and 5, the machine 1 comprises a chemical treatment unit 6 by which the advancing
stream 3 of filter material is impregnated with chemical additives, for example triacetin. - Further downstream, beyond the chemical treatment unit 6, the
stream 3 of filter material advances throughfeed means 7 provided by a plurality of guide rollers, and into ashaping device 8 of which the function is to gather theselfsame stream 3 into a continuous rope orbundle 9 of cylindrical appearance. - More exactly, the
cylindrical bundle 9 is shaped by adevice 8 of funnel-like appearance designed to induce a gradual reduction in the cross-sectional area of thestream 3; to this end, thedevice 8 is equipped with anoutlet nozzle 10 presenting across section of diameter substantially identical to the diameter of a single filter tip. - Numeral 11 denotes a garniture tongue along which the advancing
bundle 9 is enveloped progressively in astrip 12 of paper plugwrap material, decoiled from a roll (not illustrated), so as to fashion acontinuous filter rod 13. - Emerging at the outfeed end of the
tongue 11, thecontinuousfilterrod 13 is divided up by arotary cutting device 14 intosingle plugs 15. - Referring to
figure 2 , thegarniture tongue 11 appears as ablock 16 presenting ahorizontal top face 17 with alongitudinal groove 18. - The
groove 18 presents a cross section varying continuously between the infeed end and the outfeed end of the tongue, along the feed direction of the bundle, and presenting a substantially cylindrical shape at the outfeed end, of which the radius of curvature is substantially equal to the radius of a filter plug. - The
aforementioned groove 18 accommodates the sliding motion of a fabric transport belt, orgarniture tape 19, looped around two rollers 20 (one only of which is indicated in the drawings) placed at the two opposite ends of thetongue 11. - The
garniture tape 19 forces thestrip 12 of paper material to wrap by degrees around thecontinuous bundle 9. - The
continuous bundle 9 is fed onto thegarniture tongue 11 by way of a connectingelement 21 between theshaping device 8 and the selfsame tongue. - As illustrated in
figures 2 ,3 and4 , the connectingelement 21 comprises amovable inlet portion 22 and afixed outlet portion 23. - The
fixed outlet portion 23 is rigidly associated by way of a relative mounting 24 (figures 2 and3 ) with abracket 25 associated rigidly in turn with avertical bulkhead 25a of the machine frame 1, and presents a trough-like appearance with a concave face directed down toward thegarniture tape 19, of which the curvature remains constant and the cross sectional profile reduces gradually along the feed direction of thebundle 9. - In a preferred embodiment, the
fixed portion 23 and themounting 24 will be embodied in one piece. - The
endmost tip 23a of thefixed portion 23 is cantilevered from themounting 24, projecting at a level above thegarniture tape 19 and below folding means 26 of which the function is to complete therod 13 by overlapping and securing the longitudinal edges of thestrip 12 of paper material, one of which having been gummed previously by gluing means not illustrated in the drawings. - As discernible in particular from
figures 2 and4 , themovable inlet portion 22 comprises a firsttubular segment 27 consisting in afrustoconical collar 28 offered to thenozzle 10 of theshaping device 8, and a similarlyfrustoconical neck 29 attached to the collar. - The first
tubular segment 27 extends into a second trough-like segment 30 presenting aconcave face 30a directed toward thegarniture tape 19, of which the curvature remains constant and the cross sectional profile reduces gradually down to a size matching the inlet end of thefixed portion 23. - The
movable inlet portion 22 presents a plurality of throughholes 31 piercing thefrustoconical duct piece 29 and the second trough-like segment 30. - Numeral 32 denotes a hinge mechanism, in its entirety, by means of which the
movable portion 22 of the connectingelement 21 can be rotated between a first operating position illustrated infigure 2 , in which thegathering bundle 9 of filter material is transferred and guided from theshaping device 8 to thegarniture tongue 11, and a second position of disengagement from the aforementioned operating position, illustrated infigure 3 . - More exactly, the
movable portion 22 is rigidly associated with anoverslung mounting 33 hinged to thebulkhead 25a by way of ahorizontal pivot 34 placed transversely to the feed direction followed by thebundle 9 and located above the downstream end of themovable portion 22. - The
mounting 33 is connected in its turn, by way of apivot 35 parallel with thehinge pivot 34, to afirst end 36a of alinkage rod 36. - The
second end 36b of therod 36 is connected by way of apivot 37, also parallel with thehinge pivot 34, to afirst end 38a of arocking arm 38 of which thesecond end 38b is anchored rotatably to thebulkhead 25a by way of afurther pivot 39, likewise parallel with thehinge pivot 34. - The
linkage rod 36 is furnished with aknob 40, positioned above the pivot denoted 37, by means of which to operate thehinge mechanism 32. - The
mounting 33,rod 36 androcking arm 38 thus combine to establish theaforementioned hinge mechanism 32, which allows themovable portion 22 to be displaced from the operating position between thenozzle 10 of theshaping device 8 and thefixed portion 23 of the connectingelement 21 to the aforementioned position of disengagement, illustrated infigure 3 , in which themovable portion 22 is distanced from the feed path P and disposed with its longitudinal axis substantially vertical. - In operation, at the start of each operating cycle, the operator will seize the
knob 40 and pull themovable portion 22 of the connectingelement 21 upwards into the position of disengagement, then set the machine 1 running long enough for a predetermined length of thebundle 9 of filter material to emerge from thenozzle 10 of theshaping device 8. - The leading end of the
bundle 9 is inserted into thecollar 28 of themovable portion 22, by hand, and advanced through a distance substantially equivalent to the longitudinal dimension of the selfsamemovable portion 22. - The
movable portion 22 of the connectingelement 21 is then returned to the operating position, where the leading end of thebundle 9, now located under the second trough-like segment 30, is compressed by this same segment against thegarniture tape 19 together with the interposedstrip 12 of paper material. - Following this preparatory step, the machine 1 is set in motion and the
garniture tape 19 will draw thebundle 9 of filter material together with thestrip 12 of paper along thegroove 18 of thegarniture tongue 11. - Self-evidently, the step of preparing the machine for operation is rendered swift and reliable by the connecting
element 21 according to the invention, since thebundle 9 of filter material can be fed onto thegarniture tongue 11 with no need to remove any component parts of the connectingelement 21, which are typically fragile and costly. - In the event that a jam or blockage should occur along the feed path P during the manufacturing cycle, localized in the
fixed outlet portion 23 of the connectingelement 21, the operator can simply shut off the machine 1, seize theknob 40 and lift themovable portion 22 of the connectingelement 21 into the position of disengagement, clear of the feed path P. - It will be clear that with the
movable portion 22 in this position, the section of the machine 1 affected by the jam or blockage is rendered easily accessible, and normal operating conditions can be restored quickly and safely.
