Definitions

the invention relates to a device and a method for processing at least one, in particular promoted, strip of filter material of the tobacco processing industry, in particular filter tow, along a conveying path with a, in particular a housing having applicator for applying a, preferably liquid, additive to the strip.
the invention further relates to a machine of the tobacco processing industry, in particular filter manufacturing machine.
Proven processing equipment of the type described above are built and sold under the name AF2, AF3 and AF4 by the patent applicant.
Proven filter rod machines of the type described are built and sold under the name KDF2, KDF3 and KDF4 by the patent applicant.
a device for producing filter rods for rod-shaped articles of the tobacco-processing industry described are passed in the filter tow strips along a stretching line,mentssumble and Raffrange.
a suction device is arranged to suck air in the region of the pairs of rollers.
the invention is based on the idea that in the exit region of an application device, in particular in the exit region of the housing of the applicator, entrained particles and / or fluff from the conveyed strip of filter material in the ambient air are removed from the triacetin-impregnated strip, whereby the recording of the likewise with triacetin soaked lint in the strip is avoided, as caused by the laced with triacetin fluff in the further processing of the filter material strip melt holes in the filters produced therefrom can.
lint accumulations are avoided at the outlet or in the outlet region of the applicator or spray chamber, wherein the extraction of the ambient air takes place on both sides of the filter material strip.
the object is achieved in an alternative manner or the device is further developed in that based on the conveying direction of the strip after the applicator and / or in the exit region of the strip from the applicator a suction device, preferably with two lateral suction openings, is connected to a lint separating chamber, wherein in particular the suction device is provided with two suction openings, between which the strip emerging from the application device is conveyed or conveyed.
ambient air in the area of the conveyed strip is sucked by the suction device, so that flying lint that contains flying triacetin are removed from the conveying area of the strip, and then the lint in the extracted ambient air is deposited in a lint separation chamber or device.
the alternative idea or the further idea of the invention is based on the fact that the lint and / or particles entrained by the conveyed filter material strip in the ambient air of the strip are supplied to a separation device or a deposition chamber after removal by suction by means of the suction device from the surroundings of the filter material strip be in which the lint and possibly also the particles from the contaminated with Triacetintröpfchen or enriched ambient air are deposited, so that the liberated from lint and freed from particles ambient air is then freed from triacetin in further treatment processes and recovered triacetin from the Ambient air is provided for spraying the strip of filter material.
the suction openings of the suction device or the suction openings of the suction devices are aligned with their suction surfaces obliquely opposite, ie not parallel to the conveying direction of the strip.
a discharge of the ambient air, in the the lint and triacetin droplets soaked with triacetin are reached, the lint and triacetin containing air outside the applicator housing immediately following the applicator, on the top, bottom and both sides due to the conveyance of the strip by the applicator of the strip of material are removed by suction or suction.
each with a formed suction opening is arranged on both sides or narrow sides or laterally of the conveyed or conveyed strip.
the posstechniksabscheidehunt or device with a second remplisstechniksabscheidevoriques, in particular with a demister or wire mesh is connected.
a high degree of purification of the sucked ambient air is achieved and at the same time a large amount of triacetin fed back to a triacetin reservoir, which is connected, for example with a spray nozzle or the like with the applicator and whereby the strip of filter material is charged with triacetin.
the object is achieved by a method for processing a, in particular promoted, strip of filter material of the tobacco processing industry, in particular filter tow, along a conveying path, wherein by means of an applicator, preferably in a housing of the applicator, a, preferably liquid, additive the strip is applied, which is further developed by the fact that after application of the additive, in particular after exit of the strip from the applicator or from the housing of the applicator, from the environment of the conveyed strip, preferably laterally, via two suction lint and / or particles be sucked in the ambient air of the strip and / or that remote from the environment of the funded strip, in particular extracted lint are deposited in a lint deposition chamber.
a preferred development of the method is characterized in that the extracted and lint-free, and preferably emaciated by a liquid, ambient air into the environment or atmosphere of the applicator comprising device, in particular machine of the tobacco processing industry, is discharged, wherein in particular the liberated from lint, and preferably emptied of a liquid, ambient air is mixed with provided from a fresh air source fresh air.
Fig. 1 the processing device for a stripped off a bale strip 2 of filter tow, eg cellulose acetate, with continuous fibers following main assemblies that passes through the strip 2 below, on: a withdrawal line 3, a Vorreckorder 4, a stretch 6, amoverssumble 7, a Raffrange 8 and a feed path 9.
the feed line 9 is used to supply a strip portion to an inlet device of a filter rod machine 11 shown schematically, for example, known from the tobacco processing industry type KDF2, KDF3 or KDF4 the patent applicant.
a deflection plate 19 of the filter tow 2 passes into the pre-stretch 4, on the one hand by a pair of rollers 21 with the rollers 22, 23, on the other hand by a pair of rollers 24 with motor-driven rollers 26, 27 is limited.
the rollers 22, 23 are towed from the tow strip, i. they run empty with more or less resistance. If necessary, they can be powered by a motor. They can also be pressed in a manner known per se with controllable force against each other. In the Vorrecktier 4, in which the strip portion is conveyed obliquely down, the filter tow 2 is vorgereckt.
the stretching line 6 connects, in which the filter tow 2 is conveyed vertically or with a vertical component from top to bottom.
the stretching section 6 is another pair of rollers 39 of motor-driven rollers 41, 42 whose peripheral speeds are slightly greater than the peripheral speeds of the rollers 26, 27, so that the elastic filter tow 2 is defined stretched.
the roller pairs 24 and 39 thus form the actual stretching device.
the rollers 26 and 41 have a rigid, grooved surface, each contacting a compliant surface of the rollers 27 and 42, respectively.
Such roll configurations are known from the aforementioned filter tup processing devices AF 2, AF 3 and AF 4 of the applicant and, for example, in US-A-3,317,965 and US-A-3 255 506 described.
the roller pair 39 is followed by a further pair of rollers 43 whose peripheral speeds are lower than those of the rollers 41, 42, so that the filter tow 2 is slightly relaxed in its promotion.
the pair of rollers 43 has a smooth rubber roller 44, which is in contact with the steel roller 46.
the roller pairs 39 and 43 thus limit the application path 7, which in the present case is arranged approximately horizontally, in which an applicator 47 is arranged, for example in the form of a spraying device or spray nozzle.
the applicator 47 sprays the transported filter tow 2 from one or both sides with fine droplets of solvent for the filter tow material, e.g. Triacetin.
