Abstract

The invention relates to a production machine for producing rod-shaped products from a continuous strand of a continuous strip adhesively bonded to form a tube, comprising a device for applying a glue track to a strip, a format portion, in which the continuous strip into the continuous strand by shaping and adhesive bonding, and a cutting device which cuts the rod-shaped products from the continuous strand at a predetermined length, wherein the device for applying the glue track is formed by a device which applies the glue intermittently to form glue-free portions arranged at regular intervals, and a sensor apparatus is provided, which is directed towards the continuous strip or the continuous strand and generates a signal depending on the passage of a glue-free portion, and the device for applying the glue track is designed to change the length of the glue-free portions in the longitudinal direction of the glue track.

Claims (30)

1. A production machine for producing rod-shaped products from a continuous strand of a continuous strip adhesively bonded to form a tube, comprising: a device for applying a glue track to a strip,

a format portion, in which the continuous strip can be formed into the continuous strand by shaping and adhesive bonding, and

a cutting device which cuts the rod-shaped products from the continuous strand at a predetermined length, wherein

the device for applying the glue track is formed by a device which applies the glue intermittently to form glue-free portions arranged at intervals, and

a sensor apparatus is provided, which is directed towards the continuous strip or the continuous strand and generates a signal depending on the passage of a glue-free portion,

the device for applying the glue track is designed to adjust and/or change the length of the glue-free portions in the longitudinal direction of the glue track, and wherein

the device for applying the glue track is controlled depending on said signal from the sensor apparatus thereby adjusting and/or changing the length of the glue-free portions.

2. The production machine according to claim 1 , wherein

the device for applying the glue track has a controller for adjusting and/or changing the duration of the interruption of the glue application.

3. The production machine according to claim 1 , wherein

the device for applying the glue track has a nozzle, the distance (A) of which from the glue track to be applied can be changed.

4. The production machine according to claim 3 , wherein

the device for applying the glue track has a rotationally driven roller, to which the nozzle applies the glue track and which further applies the glue track to the continuous strip.

5. The production machine according to claim 4 , wherein

the nozzle has an edge portion delimiting the outlet opening and protruding in the direction of the roller, which edge portion is arranged on the edge of the outlet opening that is arranged downstream with respect to the direction of rotation of the roller.

6. The production machine according to claim 4 , wherein

the nozzle is arranged such that the centre of the outlet opening is eccentric to the axis of rotation of the roller, counter to the direction of rotation of the roller.

7. The production machine according to claim 4 , wherein

the roller is provided so as to be rotationally drivable in the opposite direction with respect to a transport direction of the continuous strip.

8. The production machine according to claim 4 , wherein

the glue has a viscosity greater than 230 mPas.

9. The production machine according to claim 1 , wherein

the sensor apparatus is arranged between the format portion and the cutting device.

10. The production machine according to claim 9 , wherein

the sensor apparatus is a high-frequency sensor apparatus.

11. The production machine according to claim 1 , wherein

the sensor apparatus is arranged between the device for applying the glue track and the format portion.

12. A method for operating a production machine according to claim 1 , wherein the length of the glue-free portions can be adjusted and/or changed by adjusting and/or changing the duration of the interruption of the glue application and/or by adjusting and/or changing the distance of the device for applying the glue track on the strip, and/or wherein the production machine is designed such that the device for applying the glue track has a rotationally driven roller, to which the nozzle applies the glue track and which further applies the glue track to the continuous strip, and the adjustment and/or the change of the length of the glue-free portions is controlled by changing the speed of the roller.

13. The method according to claim 12 , wherein

the strip is transported at a transport speed of more than 100 m/min.
