DE19718322A1 - Winder for glued connecting strips round joins between cigarettes and filter tips - Google Patents

Abstract

The winder has a rotary roller surface (8) and a non-rotary adjustable roller (9) surface with a roller duct (11) for the counter roller surface forming the groups of cigarettes (14) and filters (16). At least one of the roller surfaces has raised arms (24) in the overlap (23) between the connecting strips (17) and cigarette paper. The raised arms extend the length of the peripheral of the groups of the cigarettes and filter tips. The rotary roller surface is on one roller drum (2), and the counter roller surface is on a roller block (7) swivelling in relation to the drum.

Description

The invention relates to a device for wrapping glued connecting sheet areas around groups of cigarettes and filter plugs, the best starting from a circumferential rolling surface and a non-rotating one, relative to the rolling surface adjustable and forming a roll channel for the cigarette filter groups Counter roll surface.

In devices of the type described above, circumferential rolling surfaces are an example wise roller drums with axially parallel webs or grooves arranged on their circumference, into which the groups are placed with the connecting sheets adhering to them. By means of such roller drums, the groups become fixed or movable Counter roll surface supplied and brought to roll in this way, so that the Verbin be wrapped around the groups. To increase the form tity of the cigarette ends are these with an additional and compressed tobacco Part in the form of a so-called head reinforcement, which on free cigarettes de is quite useful because it prevents the so-called head loss of the tobacco the internal butt joints, on the other hand, are exclusively due to manufacturing means additional use of materials.

The invention has for its object the connection quality between papers and Cigarette paper while saving material at the joints of the grup pen to improve cigarette and filter components.

This object is achieved in that at least one of the rolling surfaces Ridges in the overlap area of connecting papers and cigarette paper having.

For the purposes of the invention, webs of this type can either only run around the web the rolling surface or only on the fixed counter-rolling surface or for Part to be provided on both. According to a preferred arrangement, the webs are  however, provided on the counter roll surface.

According to a further development, this results in a completely closed adhesive seam connection achieved that the webs a substantially the circumferential length of the rolling cigarette ten filter groups have the appropriate length.

A perfect glue on the longitudinal seam of the joint formed by overlapping manikin is achieved according to a further development in that the parallel and webs extending in the circumferential direction of the rolling surface by a parallel to the rotation axis of the circumferential rolling surface extending, raised web are connected. This one The rolling article groups pass over the web exactly with their facing the web overlapping longitudinal seam of the connecting leaflet, which in this way a precise Receives pressure.

The webs mentioned are preferably used in a device whose umlau fende rolling surface on a roller drum and its counter-rolling surface on a relative to the roll drum can be swiveled up or down.

The advantage achieved by the invention is that in the area of the critical impact point len between cigarettes and filter components a greater depth of impression through the webs is generated, which even with reduced tobacco storage or tobacco compression inner cigarette end a secure gluing of cigarette paper and connection guaranteed papers.

The invention is illustrated below with reference to that in the accompanying figures Embodiment explained in more detail.

Here show:

Fig. 1 shows a winding device for cigarette filter-groups in the side view,

Fig. 2 is a plan view of the rolling surface of an immovable roller block in Rich direction of the arrow Z of FIG. 1 and

Fig. 3 shows a cross section through the roller block along the line AB of FIG. 2 with an adjacent roller drum.

The winding device shown in Fig. 1 has a rotating drum 2 in the direction of arrow 1 and a 3 in the arrow direction by means of a pneumatic Stellzy cylinder 4 via a parallel lever drive 6 roller block 7 , which in this way with their moving rolling surface 8 or unmoved Counter roll surface 9 limit a rolling channel 11 be.

The moving rolling surface 8 is interrupted by grooves 12 , in which groups 13 of two outer tobacco sticks 14 coated with cigarette paper and intermediate, double-length filter plug 16 are conveyed, which are rolled over by means of a glued connecting sheet 17 at the joints 18 between tobacco sticks 14 and filter plug 16 be put together.

At the end of the expiring roll pad 7 is provided with recesses 19, immersed in the webs 21 a circumferential aligning drum 22 for aligning the rolled over or wrapped cigarette filter groups. 13

In the overlap area 23 of cigarette paper and connecting leaflets 17 projecting beyond the joints 18 , the roller block 7 has protruding or raised webs 24 relative to its remaining counter-rolling surface 9 , which webs run parallel to one another and in the circumferential direction of the rolling surface 8 of the rolling drum 2 and one of the circumferential length of the rolling Cigarette filter groups 13 have a corresponding length. While the entire circumferential length of the counter roll surface 9 permits multiple rollover of the article groups 13 .

The two webs 24 running in the circumferential direction are connected by a raised web 26 which extends parallel to the axis of rotation of the circumferential rolling surface 8 of the rolling drum 2 .

When passing the raised circumferential webs 24 and the transverse connecting web 26 , the rolling article groups 13 in the overlap area 23 on both sides and along the overlapped longitudinal seam of the connecting sheet 17 are pressed more than in the other areas, which on the one hand causes the cigarette paper of the bakstick 14 and the connecting sheet 17 and on the other hand securely connect the two overlapping ends of the connecting sheet 17 .
