Definitions
- Reference (1) shows and describes a dryer section a paper machine.
- This dryer section shows in a first part a single-row cylinder group with a single felt.
- the felt with the one on it resting web runs alternately over drying cylinders and deflection suction rolls.
- the dryer section has two rows of drying cylinders with two felts.
- the train runs alternately across the lower and upper cylinders.
- Threading strips a narrow margin (the so-called Threading strips) through the entire dryer section guided.
- Blower nozzles are used in this context to transfer the web from a drying cylinder to the others.
- the fan nozzles generate air jets that are essentially in the transfer direction of the edge strip run.
- the air jets drive the edge strip in the desired direction, namely from a first (upstream) drying cylinder to a second (downstream) Drying cylinder to the edge strip from the first Drying cylinder towards the second drying cylinder convict.
- This transfer has always stopped Problem.
- the direct transfer of the verge in certain places it was often not possible. occasionally the edge strip flutters, so that the whole Process of guiding the edge strip is time consuming is. However, this means a relatively long time Downtime of the paper machine and therefore one reduced production.
- Reference (2) also shows and describes the Transfer of a narrow edge strip in the dryer section a paper machine.
- a Air jet generated that the direction of the paper web is opposite, but describes not a free, i.e. open-chain transfer the paper strip, but the paper strip adheres to the outer surface of a cylinder and becomes scraped off by a scraper, taking the fan air the detachment supports.
- the object of the present invention is to provide a method of transferring a Paper web in a drying section of a paper making machine, where a fast and stable Guidance of the paper web can be guaranteed can, so that the transfer with higher reliability and higher speed is feasible.
- each of these one-felt cylinder groups 11 to 16 a single endless Felt on.
- Runs in the first cylinder group 11 the felt, for example, alternating with the web 9 via drying cylinder 51 and deflection rollers 51 ', preferably as Suction rolls are formed.
- 16 comes with the underside of the web Cylinders in contact. Accordingly, here are the Drying cylinders 51, 52, 54, 56 above the associated ones Deflection suction rollers 51 ', 52', 54 'and 56'; the cylinders are felted here.
- the deflection suction rollers 51 ' up to 56 ' are free of internal stationary installations and direct suction connections. Instead it is on each of these deflection suction rolls has an external suction box 59 intended. This lies in between two neighboring ones So-called pocket drying cylinders and at the point where felt F and web 9 together have the leave the first of these two cylinders, a ledge, which brought the felt up Air boundary layer strips and redirects.
- the last single felt cylinder group 16 follows a two-felt cylinder group 17 with several lower ones Cylinders 57 and several upper cylinders 57 'and with a bottom felt UF and a top felt OF. Here it runs Lane 9 meandering alternately over the lower and upper cylinder.
- Figure 2 shows another dryer section the transfer area between the last single felt cylinder group and the first two-felt cylinder group shown.
- the last two drying cylinders 73 the last one-felt cylinder group 23 and the first three cylinders 74, 74 'of the two-felt cylinder group 24 see.
- a deflection suction roll 73 ' is also included an internal suction box and before the first lower one Drying cylinder 74 a transverse deflection roller 58, which also has a stationary internal suction box.
- An automatic, rope-free deflection device for one Edge strip is in the one-felt cylinder group 23 trained, for example such that each Deflection suction roll 73 at one of its two ends known edge suction area.
- blower air devices that are symbolically indicated by arrows, as well as a Fan air nozzle 79 is provided.
- an edge suction box R (which is only in the Area of the edge strip is active), a web stabilizing device or the like may be arranged.
- a short "edge deflection scraper" 88 that only the Area of the edge strip and also covers one Fan air nozzle may be on the last one Cylinder 73 arranged.
- blower nozzles 101, 102 shown in FIG. 103, 104 are absolutely crucial. They serve for Transfer of an edge strip from the first lower one Drying cylinder 74 of the two-felt cylinder group 24 - to that first upper drying cylinder 74 'thereof.
- blower nozzles 102, 104 their air jets down and thus in the transfer direction are oriented in the opposite direction, available. It has been found that a extremely stable guidance of the edge strip is possible.
- the air jets of the nozzles 101, 103 produce a conveying effect, by quickly moving the edge strip upwards take it to the drying cylinder 74 '.
- the air jets of the two fan nozzles 102, 104 on the other hand making sure that the edge strip is in a stable position takes and immediately after leaving the first lower Drying cylinder 74 of the cylinder group 24 the right one Direction to the first upper drying cylinder 74 '.
- the two fan nozzles 101, 102 and the two Blower nozzles 103, 104 can be combined in terms of construction be and therefore carried by a single holder become.
- FIG. 3 is again on a larger scale Transfer area shown. It's the blower nozzles again 102, 104 can be seen.
- the blower nozzles 101, 103 were the Overview omitted for the sake of the drawing. How to see has the air jet 102.1 from the blower nozzle 102 Component 102.2, which is perpendicular to the direction of the verge 9, and a component 102.3 which the direction of the edge strip 9 exactly opposite is. Exactly the same applies to the air jets 104.1 from the blower nozzle 104 with the components 104.2 and 104.3.
