Detailed description of the invention
Conventionally by the curling continuous fiber with cellulose acetate and by they filter of the present invention and filter cells made bonded to each other.Also can adopt other fibers or filament material.The each continuous crisping filament tow that preferably includes cellulose acetate of core and cladding material, and before being combined in the second decorator of filter maker, these two kinds of filament tow streams are processed independently.
In Fig. 4, first cellulose acetate tow stream (11) (it will form inner core) extracted out continuously from one or more bag (not shown) and is processed by following operation: longitudinally the each filament tow of tensioning makes filament separately, thereby make filament form thin developer layer, and to spraying triacetyl glycerine plasticizer on tow.Tow stream is drawn and is entered two groups of rollers (13,13a and 14,14a) from guiding piece (12).Roller (14,14a) rotates sooner than roller (13,13a), thereby tow is stretched and launches to form width and be approximately the width sheet of the first filter material of 250mm.The width sheet of tow enters subsequently and sprays cabin (15), and before exiting described sprinkling cabin by one group of transmission roller (16,16a), the width sheet of described tow is sprayed triacetyl glycerine in described sprinkling cabin.These are all methods well known in the art.The tow (11) of the processing advancing is continuously aggregated and draws via configuration mould (14) by decorator (13) and endless belt.In this mould, described tow stream is through also radially directly contacting with tow filament, make them by Fast Heating, and adhering to each other by the dissolution of triacetyl glycerine, thereby form the inner core (11a) of the tobacco smoke filtration material for example, with expectation cross section (, star) as shown in Figure 1.Mould (14) and the inner core (11a) therefore forming can have any intended shape, for example star, triangle, pentagon or heart.
Second of cellulose acetate tow longitudinally advances stream (21) to be used to form skin.Equally, described tow is extracted out continuously from one or more bags and is processed by following operation according to method well known in the art: longitudinally the each filament tow of tensioning makes filament separately, thereby make filament form thin developer layer, and to spraying triacetyl glycerine plasticizer (not illustrating at Fig. 4) on tow.Once through processing, described the second tow stream is just applied in around inner core in the following manner.
The inner core (11a) with the continuous propelling of the tobacco smoke filtration material of expecting cross section is advanced to and passes the hollow tube (15) in shell (16).Second of filament tow longitudinally advances stream (21) to pass around hollow tube by other decorator and endless belt, and described propelling stream (21) is advanced along the direction identical with inner core (along arrow 23).Along with core feeding enters and exits hollow tube, the second tow stream (21) is around tangible inner core compression, thereby formation is around the filtering material skin (21a) of annular substantially of inner core (11a).Hollow tube (15) is positioned in shell, and inner core is medially positioned in finished product filter.During the second tow stream is through shell, described tow stream penetrates by endless belt and is combined component with the parcel filament contact of the second tow stream to activate the triacetyl glycerine being included on described tow stream, and then they form coherent, bonding, to allow passage of smoke (outward) layer around tangible core.By make that outer layer ring forms around (interior) the extending longitudinally core of continuous propelling with non-circular cross sections synthetic advance continuously filter stick (31) advantageously forming after by cooling immediately.Wrapping paper in a usual manner-arrange by common package decoration device, described common package decoration device will be arranged on the upstream of next-door neighbour's cutter.Therefore, this operation provides a kind of filter rod (31), and described filter rod (31) comprises the inner core extending longitudinally (11a) of tobacco smoke filtration material; And the skin extending longitudinally (21a) of the tobacco smoke filtration material engaging around described inner core extending longitudinally, wherein said inner core extending longitudinally has non-circular cross sections.Described filter rod can cut into by method as known in the art and be suitable for using subsequently (, as filter or filter cell or for other filters or filter cell combination) single or multiple filters or the length of filter cell.
Therefore, enter mould and decorator device to form (non-circular) shape of expecting for the filament material of core components extending longitudinally, and like this form core subsequently along with it through other decorator and by outer field filament material around and surround, thereby continuous filter rod is provided.Because after core forms, described core is pulled and combines in the second decorator with annular material, so above-mentioned manufacture method has overcome the problem of the clearly demarcated contour shape that forms tangible core and holding core.
