By US-PS 4281670 known filter tip setting machines following details are arranged by Fig. 1:

The cigarette that import cylinder 1 will be produced on cigarette machine is transported to two ladder cylinder 2 places, and the cigarette elimination ladder that they import staged is arranged into two delegation and leaves the compartment of terrain and export to combination roll 3 between cigarette.The filter rod that arrives on the cutting-cylinder 6 from hopper 4 is cut into the filter tip that twice is used length by two cutting dives 7; On ladder cylinder 8, become ladder; Be transferred cylinder 9 and line up the continuous row in front and back; And, be accelerated in the interval that cylinder 11 outputs to cigarette on the combination roll 3.This cigarette-filter tip-group, of cigarettes is pushed together, so they are right after mutually vertically.They are transmitted cylinder 12 transmission then.

Connecting paper tape 13 draws from chart drum 14 by means of emptying roller 16.Paper tape 13 turns to around a primary breaker 17 that has sharp seamed edge; By glue spreader 18 gluings and cut.The connection small pieces (section) that block are bonded on cigarette-filter tip group on the transferring roller 12, and roll around cigarette-filter tip group by means of rolling plate (Rollhand) 23 on cylinder 22.Two cigarettes with filter tip of making are transported to cutting-cylinder 26 by drying drum 24, pass filter tip by means of central cutting knife there and cut, and are shaped to single cigarette with filter tip, the defective cigarette with filter tip of meanwhile throwing out.By transferring roller 27 with compile cigarette with filter tip row of turning device 29 upsets of cylinder 28 cooperatings and meanwhile this row's cigarette is sent to through transferring roller 27 and compiles among the unturned cigarette with filter tip row of cylinder 28 operations.Cigarette with filter tip arrives the cylinder 32 of dishing out via check cylinder 31, implements material casting and cross the head scanning that cigarette with filter tip is also carried out in the Cheng Qian on the cylinder 32 of dishing out.Discharge cylinder 34 with brake drum 33 cooperatings is laid in cigarette with filter tip to discharge and is with on 36.Represent cut and punching machine with 41, Fig. 2 represents its details.

Still with the 13 connection bands made of paper of representing gluing, its quilt in the zone of cylinder 19 is blocked into connection small pieces 13a in Fig. 2.Represent in the cut line of band 13 throughput directions 40 processing with 13b.Processing perforation 13c in this external this zone, they extend along throughput direction 40.Perforation 13c preferably extends to cut line 13b from cut line 13b, so they produce two annular perforations tracks in the filter tip district of the cigarette with filter tip of making, bypass air can flow into filter tip inside by them from the outside.Cut and punching machine 41 have a so-called TEA laser instrument 42, and (Junkersstrape 5, D-82178 Puchheim, DE) laser instrument of the model IMPACT 3000 of Xiao Shouing as LUMONICS GmbH company.That here relate to is CO ₂The laser machine, they can be launched and continue about 1 millisecond and contain the very extremely short laser spiking pulse of macro-energy.Laser instrument 42 is by controller 43 control, the driving rotating speed of the filter tip setting machine that controller is represented according to Fig. 1 the following moment to laser instrument generation control signal, that is, should on band 13, generate the cut line 13b and the 13c that bores a hole this moment.Arrive the lens 46 of a so-called diffraction, focusing with the ray tracing of the 44 laser spiking pulses of representing, as the Coherent of company, Inc., 2301 LindberghStrect, Auburn, Calif.95602, what USA sold is the sort of.Diffraction lens can be designed to optics, and they become wire ground along each needed direction expansion the ray tracing of concentrating.These lens 46 are designed to, and it is deformed into a line 46b (13b is corresponding with the cut line) and four vertical with it lines (13c that also bores a hole is corresponding) with laser spiking pulse 44.Between lens 46 and band 13, also have a barricade 47, a wire groove 47b (13b is corresponding with the cut line) and four hole line 47c perpendicular to the wire groove (13c is corresponding with perforation) are arranged on the barricade 47.Groove 47b and hole line 47c are used for making through lens 46 preformed linear laser spikes and more strictly are shaped and qualification more accurately.Therefore, barricade 47 is removable, so that can change size and the distance of perforation 13c.The present invention allows to generate cut line 13b with extremely short and the very big laser spiking pulse of power in band 13 in band 13 motion processes.Meanwhile can also be by this same laser spiking pulse processing perforation.Undoubtedly, adopting the present invention also can process in band 13 bores a hole 13c and does not have cut line 13b.

The present invention can change over and make two spikes of laser instrument 43 sequential transmissions, and one of them makes cut line 13b, and another makes perforation 13c.

At last, two laser instruments can be set also, one of them only launches the photopeak pulse that is used to generate cut line 13b, and another emission is used to generate the spike of perforation 13c.

If only limit to generate cut line 13b, then can replace the lens 46 that illustrated diffraction focuses on and use a kind of better simply cylindrical lens.

Illustrated has represented that for example band 13 is around cylinder 19 guidings.If want identical perforation 13c, lens 46 additionally are designed to compensate the distortion between the cut line 13b so.

, also the band in small pieces cut district and/or punch block 13 can be directed in the plane for advantageously some application target, for example by means of the metal tape of a porous, band 13 and small pieces 13a are fixed on this metal tape by air-breathing.

Increase continuously or reduce to bore a hole and under the situation of not changing barricade and non-interrupt run, to reach like this, that is, be preferably on two branch barricades and make the rectangle perforation and they are overlapped each other.Move with respect to another piece by a branch barricade, can reduce or increase effective lap, and thereby the influence " ray window " size.
