Definitions
- the invention relates to a method according to the preamble of claim 1 and a device suitable for carrying out this method according to the preamble of claim 6.
- Continuously working paper processing machines are fed with paper webs that are unwound from rolls.
- a roll ends, it is replaced with a new roll without stopping the processing machine.
- Roll changers are known which work with the so-called "flying roll change".
- the beginning of a new roll which is on hold is first provided with an adhesive tip.
- the new roll is rotated and brought to a peripheral speed which corresponds to the speed of the is synchronized from the almost empty roll running off.
- the web is pressed onto the new roll at the right time so that it touches it in the area of the adhesive tip.
- the beginning of the new web is glued to the running web.
- the running web becomes short separated behind the glue point.
- the section of the old web referred to as the so-called “adhesive flag” should have a predetermined length from the adhesive tip to the severed end, so that the adhesive flag passes through the printing press no interference occur.
- the flags can cause interference in the downstream processing stations even if they are all of a uniform prescribed length. Since the cut is always made with a delay due to the inertia of the cutting device and the cycle times of the control, the flag cannot be as short as desired 2 be cut off. For example, B. the delay time 10 ms and the web speed 15 m / s, the flag is at least 150 mm long.
- the first part of the object is achieved by the characterizing features of claim 1, the second part by the characterizing features of claim 6. Further advantageous features of the invention are the subject of the dependent claims.
- the paper web 1 wraps around the deflection roller 3 in an angular range of approximately 180 °.
- a roller 4 is redirected there and continued approximately parallel to the direction in which it runs to the deflection roller 3, z. B. to a web press.
- a knife 7 is fastened, the cutting edge of which in the looping area extends close to the outer surface of the deflecting roller 3. There is only a small distance between the cutting edge of the knife 7 and the outer surface of the deflection roller 3, for. B. about 2 mm.
- the cutting edge of the knife 7 is preferably serrated and extends over the entire working width. It points in a substantially tangential direction opposite to the movement of the paper web 1.
- the device works as follows: As soon as the approach of the flag 2 at high speed, for. B. 15 ms, the run-up line 10 has passed, the flag is on the one hand by the centrifugal force, on the other hand by the opposing resistance of the ambient air in a movement that is similar to the movement of a whip cord. Before the approach of the flag 2 reaches the cutting edge of the knife 7, the flag 2 is subjected to air blasts from behind from the blowing nozzles 8, 9, the speed of which is significantly greater than the speed of the paper web 1. They support the uprighting effect of the centrifugal force and separate the free end of the flag 2 from the paper web 1. This is at least approximately radially aligned and thus reaches the cutting edge of the knife 7. There it is cut to an insignificant remainder of a few mm. 4
- the exemplary embodiment according to FIG. 2 differs from the exemplary embodiment illustrated by FIG. 1 in that the holder 6 of the knife 7 is fastened to a suction box 11. Its interior is connected to a suction device, not shown. It has a suction slot 12, which is located directly next to the knife 7.
- the deflection roller 3 is assigned an endless rotating suction belt 13.
- the active run of the suction belt runs at a distance of about 20 to 60 mm parallel to a tangent that touches the jacket of the deflection roller 3 in the looping area at a point just before the cutting edge of the knife 7.
- a suction box is arranged in the usual way, which is open on the side facing the active run.
- the vane 2 In operation, the vane 2 is separated with its free end from the paper web 1 lying against the deflection roller 3 under the action of the centrifugal force and the air blows emerging from the blowing nozzles 8, 9 and flung against the active strand 14 of the suction belt 13. The flag is held there by suction.
- the suction belt 14 is preferably driven at a speed which is higher than the peripheral speed of the deflection roller 3. As a result, the flag 2 is pulled over the knife, so that a safe cut is ensured in the immediate vicinity of the attachment of the flag 2. 5
- the suction belt 13 can, however, also run at a speed which is lower than the peripheral speed of the deflection roller 3. In this case, the free end of the flag 2 is braked and the flag 2 is kept taut. This also facilitates the exact cutting of the flag.
- FIG. 4 differs from the embodiment just described according to FIG. 3 in that the suction belt 13 is replaced by a rotating roller 15. It has a perforated jacket and is connected to a suction device, not shown.
- a shielding plate 16 is arranged in the interior of the roller 15, which only leaves one suction zone 17 free, which extends over an angular range of around 60 ° and lies approximately opposite the middle part of the looping region of the deflection roller 3.
- the jacket of the roller 15 can be provided with a friction-increasing coating, e.g. B. with a rubber coating.
- the roller 15 has an impermeable, preferably rubberized jacket.
- the shield plate 16 is missing, as is of course the connection to a suction device.
- the roller 15 only acts as a support and conveying element for the flag 2. It can be synchronized with the deflection roller 3 with regard to the peripheral speed, but it can also advance or lag. In any case, it contributes to feeding the flag 2 to the knife 7 in a reproducible position which favors the cut.
- the exemplary embodiment in FIG. 5 has two deflecting rollers 3a, 3b, the deflecting roller 3a being connected upstream of the deflecting roller 3b in the course of the goods.
- the paper web 1 wraps around the two deflection rollers 3a, 3b each in an angular range of approximately 90 °, so that it is guided from the downstream deflection roller 3b in the opposite direction to that in which it is fed to the upstream deflection roller 3a becomes.
- the paper web runs through a straight line section 18.
- a suction box 19 with a perforated suction wall 20 is arranged adjacent to it. The suction wall faces the paper web strand which is currently passing through the straight line section 18.
- the distance between the paper web 1 and the suction wall 20 is approximately 20 to 50 mm.
- a blowing nozzle 9 is arranged, the blowing jet of which is directed into the gusset between the deflection roller 3a and the suction wall 20.
- a knife 7 is arranged in addition to the downstream guide roller 3b.
- the flag 2 is separated from the paper web 1 on the upstream deflection roller 3a by centrifugal force, supported by the action of the air blast emanating from the blowing nozzle 9.
- the free end of the flag 2 is held on the suction wall.
- the flag 2 is fed to the knife 7 in the streamlined state.
