- the closed rope loop is partly over pulleys 39 and along the Web path, for example, via loose rope sheaves, that sit on the guide roller journals, about the same Web guide rolls through the same facilities the processing station (dryer, press equipment, Finishing unit 29) performed on the or through which the material web 3 to be led.
- the ropes 37 are by means of a drive device 41 either in the direction of the path and can be moved in the opposite direction.
- the in Basement 27 arranged drive device 41 comprises here one with a drive and braking torque Traction sheave 43, as for example is used in elevator construction with at least one of the ropes 37, preferably with both Ropes, interacts.
- the drive device 41 is preferably designed such that both the Direction of displacement of the guide elements as well whose displacement speed can be varied.
- the ropes 37 can preferably be at a standstill out in both directions with desired acceleration to a given speed be moved.
- each of the ropes 44 is a rope tensioning device for each of the ropes 44 provided, each three Include pulleys over the circumference of the ropes 37 are carried out in some areas.
- Deflection pulley of the cable tensioning devices 44 hangs a weight that one, also known as a tension pulley Deflection pulley - as indicated by arrows - pulls vertically downwards and thus the ropes 37 clamp independently.
- a tension pulley Deflection pulley - as indicated by arrows - pulls vertically downwards and thus the ropes 37 clamp independently.
- a flexible hose 45 is attached, which means several hose fastening elements 47 between the ropes running parallel to each other 37 arranged and held on this.
- the Hose 45 runs parallel, but at least in essentially parallel to the ropes 37 free end of the hose 45 is a recording head 49 provided in two positions in FIG is shown, namely in the takeover area 5 for Takeover of the threading strip / the material web from the selected means of transport 19 and in the transfer area 7, in which the strip / web to the Transfer device 31 is transferred.
- the intake head 49 has such an opening designed that when transferring over a Web guide roller or the like its outer contour adjusts as shown in the transfer area 7 Position visible.
- the hose 45 is together with the ropes 37 on a purely exemplary here winding drum located in the basement 27 51, preferably completely, can be wound up Structure described below with reference to Figure 2 becomes.
- the other is the Recording head 49 facing away from the end of the hose 45 connected to a tubular connecting part 53, this in turn with a vacuum source, not shown is connected so that the hose 45 can be subjected to a negative pressure.
- the function of the hose 45 is explained below of a transfer process described in more detail. In the following it is assumed as an example that only one separated from the material web 3 Threading strips from takeover to Transfer area is transferred.
- the hose 45 the while the machine is running preferably completely, but at least so far is wound on the winding drum 51 that the normal operation of the machine bothers when starting up the machine or a web break by driving the ropes 37 in relocated the takeover area 5. This process is done manually or by an appropriate control the drive device 41 triggered.
- the from Transport means 19 expiring threading strips by applying a pressure to the hose Vacuum sucked in and through all the way through to the connector 53 led.
- the transport respectively guide the threading strip the air flow inside the hose causes or supported.
- the connecting part 53 is a post-processing facility, in which the threading strip is caught, for example and / or crushed or a recycling plant or the like is supplied.
- the threading strip is caught, for example and / or crushed or a recycling plant or the like is supplied.
- the rate of displacement of the hose respectively that of the guide elements 35 during the transfer process is smaller, preferably significantly lower than the running speed of the Material web that corresponds to the machine speed Corresponds to the time of the threading process.
- the means the transfer speed of the threading strip is significantly lower than the machine speed, so that the threading strip is secure can be transferred.
- the threading strip or the entire material web with, for example, 2000 m / min is fed through the paper machine while the Transfer speed of the threading strip for example, is only 300 m / min. Because the threading strip picked up by the hose 45 and the preferably led out of the web path Part of the threading strip through hose 45 is carried out is a slow and safe transfer of the threading strip from the takeover to the Transfer area possible without having to during the transfer process the machine speed is reduced must become. By removing the in the Tube of the part of the threading strip sucked in, which is not led to the transfer area, the threading strip will run onto the Recording head 49 due to the speed difference between the running speed of the material web and hose transfer speed avoided. The longitudinal stretch of the strip can, as I said, by vacuuming the hose on one desired value can be kept.
- FIG. 2 shows a section of that shown in Figure 1 Transfer device, namely a Part of the take-up drum 51.
- the winding drum 51 has on its outer jacket 55 a spiral web 57 on, which is incorporated into the outer jacket 55 or is attached to the outer jacket.

- the rotating one Storage of the winding drum 51 takes place here on the one hand via the compensation line 71 and on the other hand either by means of Centering rollers or a bearing journal described above.
- the take-up drum 51 With a rotary movement the take-up drum 51, which by a Relocation of the respective ropes 37, 37 'by means of of the drive device 41 is generated Depending on the direction of rotation - winding drum in Figure 2 shifted to the left or right that the Control pushes against a flank of the web.
- the principle of displacement, according to which the take-up drum shifted corresponds to one in one Threaded hole screwed screw, being the bar corresponds to the external thread of the screw and the control the function of the internal thread takes over.
- the take-up drum 51 is the one shown in FIG Embodiment compared to an imaginary parallel to the seating surface 93 of the chair 79 extending horizontal H by an angle ⁇ inclined, that of the slope of the spiral Corresponds to web. This ensures that the hose and the ropes are routed constantly, here vertically, on the take-up drum run up and down, which is explained in more detail below becomes.
- the Hose also above the foundation, i.e. inside the machine, wound on the take-up drum can be. This can be done, for example be positioned above the transfer area 7. It should also be noted that the hose 45 both at the first end region 63 and that second end portion 67 of the winding drum 51 attached can be either on the side of the Winding drum, on which this is telescopically into the through opening of the connecting part engaging compensation line stored or on the opposite side.
- the entire travel of the take-up drum is depending on the length of the hose 45, which is up to Can be 60 m and above and the diameter the winding drum, for example 2 m and the slope of the spiral leading to Example can be 250 mm.
- the take-up drum is their Length about 3 m, which is also roughly their displacement equivalent.
- Figure 3 shows a side view of another Embodiment of the winding drum 51, the Design and function of the reference to FIGS. 1 and 2 corresponds to the winding drum explained. This also has one on its outer jacket 55 spiraling - not shown in Figure 3 - Footbridge. The following is therefore only on the storage of the winding drum 51 closer received.
- the take-up drum 51 is on its suction connection facing - in Figure 3 right side the compensation line 71 stored in the Through opening of the not shown in Figure 3, connecting part connected to the vacuum source intervenes.
- the compensation line 71 is in a bearing bore of a first bearing support 93 rotatably held by means of several only with fasteners indicated with dots 95, here screws, on side members 97 and 97 'is laterally attached.
- the parallel and spaced apart longitudinal members 97, 97 ' which is a carriage for the take-up drum 51 form, is in the representation according to Figure 3 shows only the longitudinal beam 97.
