A paper web 4 can be unrolled from the paper roll 2. The paper web 4 has a width of preferably more than 350 mm.
The paper processing device 1 according to
Between the paper supply receiving device 3 and the rolling arrangement 5, a web tensioning control device is provided, by which the web tension is controlled. In addition, a lateral edge controlling device is provided, with which the paper web 4 is able to be conveyed in a controlled manner with regard to the position and direction of one or both lateral edges of the paper web 4.
The paper processing device 1 according to
So that a paper web section 6 in the rolling arrangement 5 can be formed to a paper body, the paper web 4, originating from the paper supply 2, must be firstly cut to a desired length. This takes place in the high speed paper web conveying arrangement, where a perforation is formed in the paper web 4 by means of perforating blades, and where a paper web section 6 is separated from the paper web 4 by means of a crosscutting roller where the perforation was formed.
So that in the rolling arrangement 5 a paper web section 6 can be formed to a paper body, the paper web 4 originating from the paper supply 2 must firstly be acted upon with a fold. This takes place in the paper web conveying- and folding device 19. The paper web conveying- and folding device 19 comprises five conveying rolls, wherein a conveying roll is formed as a profiled folding roll, which folds or creases the paper web section 6. The folding roll lies against a counter-roll, which is coated, and which has a conical cross-section with up to 2 mm conicity. The conicity is preferably less than approximately 1 mm and/or more than approximately 0.5 mm, for example approximately 0.7 mm.
The rolling arrangement 5 according to
For fixing the edge of the paper web section 6 on the circumference of the shaped paper body, the paper which is to be processed is acted upon by an additive which is formed from water. This takes place in the additive adding device 11, which wets the lower region 12 of the rolling drum 8 with additive, i.e., substantially opposite the cover 9 on the underside of the rolling arrangement 5, by means of a rotor application system, so that in the further process the paper body is also acted upon with the additive. In this respect the paper is wetted indirectly, namely by the rolling drum being wetted.
Following thereon, the paper body arrives into a cutting arrangement 13, where the paper body is cut to size so that one or more paper sticks are formed therefrom. Provision can be made that the paper body is firstly cut at the ends (end cut-off), and then the body (cut at the end side) is cut up into several parts (body cutting), wherein these cut parts form the paper sticks. The devices for the end cutting-off and for the body cutting can be separated spatially from one another in the cutting arrangement 13 or respectively in the paper processing device 1, and/or able to be controlled/regulated separately. Provision can also be made that the end cutting and the body cutting take place in a combined process step with accordingly configured cutting device 13.
The end pieces are disposed of; for this a sorting- and/or screen device can be provided, which sorts out the short end pieces and further conveys the (longer) paper sticks. Preferably, the ends are separated by the cutting device 13, wherein they fall as paper residues or waste into the disposal device 14 which is arranged substantially under the rolling arrangement 5.
A further station of the paper processing device 1 according to
A further station of the paper processing device 1 forms a drying device 17. It comprises a spiral conveyor, i.e., a conveying trough arranged in a helical manner, with a gradient. The spiral conveyor is able to be acted upon with warm or hot air by means of a blower device, so that the paper sticks which are conveyed in the spiral conveyor are dried, for instance for the residue-free removal of the (water) additive.
A further station of the paper processing device concerns a post-treatment drum 18, in which the paper sticks can be fed to a post-treatment. A post-treatment can comprise a coating or a hardening or a quality control. The post-treatment drum 18 has a hexagonal cross-section and rotates with adaptable speed.
The paper processing device 1 according to
With the paper processing device 1 and/or with the paper processing method, accuracies or respectively tolerances are produced, which with respect to the nominal length of a paper stick are approximately 1/10 mm and with respect to the nominal diameter of the stick are approximately 1/100 mm. Within a manufacturing process, in which large quantities of paper sticks of particular nominal length and of particular nominal diameter are manufactured, the values named herein for deviations/tolerances are less due to the process stages and device components which are precisely coordinated to one another.
