Generally speaking, the device according to the invention consists of an endless flexible belt running at high speed over a number of roles aggetriehenwlrd, as well as a formation channel, through which the belt moves during part of its movement. The forming part gradually changes the cross-sectional configuration of the ribbon from a flat one Form via a generally U-shaped shape and then into an arcuate cross-section in the form of a rod. That Band returns after passing through the forming part back to its normal flat configuration. Before the formation of the band in the Formierungstell is based on a Place a supply roll of Zlgaretten paper on the surface of the Ribbon is conveyed, and the cigarette paper becomes a cross-sectional configuration mediated similar to that mediated by the forming part of the band, while the Belt moved through the forming part. According to the invention, a filter plug with twice the length and with it applied Strips or stripes of adhesive introduced into the moving paper during the forming process, the adhesive forming the plug inside the Attached to a tube or rod. As the paper moves, a thin strip of glue is applied to one edge of the cigarette paper is applied, thereby maintaining the paper in the tubular configuration after the tube leaves the formation section. The rolled cigarette paper leaves the forming section in the shape of a stick and has double length filter plugs equally spaced inside the rod. The distance between The filter plug is of course twice the length of the den Tobacco-absorbing part of a later trained single Cigarette filler tube.

The formed rod is then after leaving the belt separated between the double length filter plug, leaving a length of tube with a double filter in the center. These lengths are then taken through the middle of the filter plug separated to form two cigarette filters plugs that have smooth filter ends.

Between the lumps 4 and 6, the belt runs through an essentially horizontal forming part 24. This forming part 24 is in the form of a channel that has an internal surface configuration that varies along its length; that the tape is given a similar configuration as it passes through the forming member.

There are shown in FIGS. 2 and 3 and 4 three sections of the forming part 24.

As soon as the tape enters the forming position 22 at 26, its cross-sectional configuration from a flat or plan Configuration eventually changed to a circular configuration via a generally U-shaped configuration, and because the cigarette paper is worn on the surface of the belt the cigarette paper takes a configuration similar to the tape on.

The double-length cigarette filter plugs go into the Cigarette paper is introduced while having the generally circular cross-sectional configuration shown in FIG. 4 by means of an insertion tube 28, such as welter explained below.

Before insertion, the filter plugs or the paper are provided with one or more strips of adhesive so that the How to attach plugs inside the cigarette paper Welter explained in detail below. As soon as the tape and the Pass the cigarette paper through the forming station, the forming plate uniformly closes the paper from a U-shape to an arcuate or tubular shape, and at this point the filter plugs are opened introduced. The presence of the filter plug with uniform Distance along the length of the cigarette paper prevents the cigarette paper during the forming process The strings are thrown or distorted.

Before the cigarette paper is rolled lengthways on itself, a thin layer of adhesive is applied to one edge surface upset. The application of the thin adhesive strip can by means of a disc roll 30 which is partially immersed in an adhesive bath 32, in this

binding with the rod 36 and a horizontally movable arm 40 exists, which in turn can be pivoted on a connecting fetab 42 is eccentrically and pivotably connected to a wheel 44. You can see that the turning of the wheel becomes a reciprocating movement of the rod 36 fühfct. It results furthermore that one can of course also use a device other than that shown in FIG. 1 for the switching in the same way or apply reciprocating motion of the rod 36 can.

There are filter plugs in the push-in tube 28 one after the other by means of an opening or slot 46, see FIG. 1. The stoppers are, of course, placed in the tube 28 inserted while the push-in rod is in its outermost Location (right with respect to figure 1) and then moved the push rod to the left (with respect to FIG. 1) by moving the stopper along the tube and into the cigarette tube rod 34, which is being trained. The opening or slots 46 in the tube can be on the side or are in the upper end and can be pre-formed cylindrical Filter plugs or the filermaterlal can be applied in bulk.

If pre-formed filter plugs, such as those made from acetate material, are used, a simple reservoir can be placed in the Drawings not shown over the vein adjacent to the slot 46, with a suitable punch or displacement arrangement pushes the plugs one after the other into the slot as the push-in rod reciprocates.

As explained above, filter material can also be used in Mass to be applied. This filter material is in roll form so that it is wound up in tape form. the Fig. 5 shows a plan view of a device that together with the device according to Flg. 1 for inserting the filter plugs can be used in preparation for the insertion into the cigarette rod.

In FIG. 5, the pressure tube 28 and are shown in DR the push rod 36 shown in section. Adjacent to the opening slot 46 is a flat plate 48 and a strip the filter material 50 is fed onto the plate 48 and then by means of a suitable arrangement along the dashed lines Line 52 disconnected. Then a transport plate 54 moves to the left, see FIG. 5, moving the separated one Filter strip 50 "in a layer between slot 46 and a filter plug compression member 56 / which then extends forward moved in the direction of arrow 58, whereby the 'piece 50 · is pushed into the insertion tube at 60. The front edge 62 of the filter plug compression part has a concave shape in cross section, so that when the compression part is moved in the layer 64 shown in dashed lines hereby forms an inner surface on which the push-in tube 48 is formed. The push rod then moves to the left, see the wings. 5, sliding the compressed stopper in the cigarette rod.

A device similar to that shown in FIG. 5 can also be used for inserting preformed stoppers into the tube 28 are applied, the plug in front of the compression edge 62 by a vertical storage container or the like. are fed.

There may be an adhesive for securing the filter plug in the Inside the cigarette rod either the filter stopper as such or the cigarette paper can be applied before transferring it into a tube.

If the glue is to be applied to the filter plug, this can easily be done by having a Adhesive applying nozzle or wick 66 over the indentation tube 28, see Flg. l, is arranged, as well as an opening at 68 in the top of tube 28, whereby the adhesive is applied directly to the filter plug while the same at the nozzle 66 by means of the push rod 36 is moved.

Optionally, the filter plug can be placed inside the cigarette rod and later in the finished cigarette tubes

Adhesive can be applied to the cigarette paper. This can be accomplished in that one or more rollers applying the adhesive, the cut away at their periphery Have parts aligned with roller 30 in adhesive bath 32 will. As soon as the rolls are rotating, their remaining peripheral parts come in uniformly with the paper web 16 Lets contact and turning the wheels at certain intervals easy to advance so that glue is applied to the paper web at the points where the push-in bar will later go puts down a filter plug.

After the tape 2 has passed through the forming device 24 1st, there is a turning around the roller 6, however the cigarette paper jumps past the roll 6 in the form of a stick, where it can be subdivided into individual length sections by means of suitable SCherentelle 70 takes place. As explained above, the rod 34 of the cigarette paper is first cut into individual pieces Cut pieces that are twice the length of a single finished cigarette tube. This means that the scissors 70 the stick of the cigarette paper maker between the filter stoppers double length, creating a tube with double Length is obtained, which is arranged in the center of the filter plug having twice the length.

The scissor parts as shown very schematically in FIG are comprised of lever-like scissor blades 70, more conventional Type that is normally open by means of a spring arrangement State held and by means of a cam action in synchronized movement can be closed with the moving cigarette rod. As indicated above, the scissors part double the length of the rod between the filer plugs, creating a Cigarette stick remains in the middle with double length. It A separated tube of double length from the scissors is shown omitted according to FIG. 1, from where the same is transported away for the subsequent separation to form two cigarette paper tubes. This adjoining Separating or cutting up can be by means of a cutting wheel or knife or other appropriate conventional means Device to be executed.

Since the production speed of the cigarette rods is very significant the scissors are preferably for running a longitudinal movement with respect to the rod 34 so arranged, that a movement takes place herewith and at the same speed as the rod 34 during the Scinneld process. With regard to the reciprocating horizontal movement of the scissors shown by the arrow 72 in FIG synchronize this with the movement of the push rod 36, and a similar device can be used for conveying a backward = and moving motion can be applied.

By applying filter plugs that are twice the length you need insert only half the number of plugs as if plugs with a single length were used and this requires increased production.

As stated above, it is possible to use pre-formed filter plugs or use rolled film, and the latter is less costly. Standard paper is also possible or to wear a more expensive moisture proof paper, the device being equally good is working.
