Definitions

  • the invention relates to a method according to the preamble of claim 1 and one for Implementation of this method suitable device according to the top handle of Claim 2. (DE-A-3 606 319).
  • the so-called "adhesive flag" section of the old Have a predetermined length from the glue point to the severed end, so that there is no interference when the adhesive flag passes through the printing press occur.
  • the flags are in the downstream processing stations can cause interference even if they are all uniform have the prescribed length. Since the cut always only with one through the inert mass of the separation device and due to the cycle times of the control If there is a delay, the flag cannot be cut as short as desired. is e.g. the deceleration time is 10 m / s and the web speed is 15 m / s at least 150 mm long.
  • the new track is initially set up in a connecting route with little Distance parallel to the running web and on their speed accelerated. Then one of the two lanes becomes one between the lanes adhesive strips glued on both sides and then together with the adhesive strip pressed against the other track.
  • the trailing end of the running web is with cut off a knife arranged at the beginning of the connecting path.
  • the between the glue point and the interface section of the running web is the Banner.
  • At the end of the link is a short distance from the outer surface arranged a second knife, the cutting edge against the Direction of the paper web is directed. This knife is used to separate the premature start of the new train. It is not suitable to shorten the flag because this is located on the inside of the sheet when passing the deflection roller the web passes so that it is between the web and the outer surface of the deflection roller is clamped.
  • the first part of the task is characterized by the characterizing features of claim 1 solved, the second part by the characterizing features of claim 2. Further Advantageous features of the invention are the subject of claims 3 to 11.
  • the Blower nozzle 8 is pressurized with compressed air. This will be on the side on which the flag is located 6 is located, generates an air flow rectified with the web speed, which the Paper web essentially over the entire length of the straight section 4 accompanied. The flow rate is higher, preferably considerably greater than the web speed.
  • the flag 6 the blowing nozzle 8 has happened, it is caused by the negative pressure generated by the air flow from the Paper web 1 separated and erected.
  • the straightening effect is supported by the centrifugal force effective in the deflection area on the deflection roller 2.
  • the flag 6 In the air flow, who sweeps the paper web 1, the flag 6 retains its substantially rectangular Alignment with paper web 1 until it reaches knife 7. There it is up to a remainder of a few mm, which is essentially the distance of the Knife 7 corresponds to the paper web 1, cut off.
  • the process is repeated with every role change, i.e. at intervals of about 15 - 60 min.
  • the blowing nozzle 8 is inclined above the deflection roller 2 on the inlet side arranged.
  • the blow jet hits in the loop area or before Wrapping area on the paper web 1.
  • the Coanda effect hugs you the air flow to the paper web 1 and accompanies it at least up to the knife 7.
  • the deflection causes the air flow to move in the direction perpendicular to Paper web widened and evened out.
  • the knife 7 is on an extra table mounted rod 9 attached. Touched in the active position illustrated in Figure 2 the rod 9 the tangentially passing paper web 1, without noteworthy distract. This avoids that the paper web under the influence of Airflow flutters. After cutting off the flag 6 it will Knife 7 by pivoting the rod 9 in the direction of arrow 10 in the Bring ready position, in which the rod 9 no longer touches the paper web. In it remains in this position until the next flag approaches.
  • the exemplary embodiment according to FIG. 3 initially differs from that of FIG. 2 in that the straight section 4 an approximately parallel to the continuous paper web aligned baffle 11 is assigned so that between Paper web 1 and baffle 11 is a channel. This will make the air flow that the Raising the flag 6 causes, guided and held together.
  • Another difference to Figure 2 is that as a support for the Paper web 1 a rod or roll 12 is provided on the back of the Paper web 1 is arranged. It is attached to a swivel arm 13, the one Swiveling in the direction of arrow 14 from the active illustrated in Figure 3 Position in a standby position allowed.
  • the deflection roller 2 on the inlet side in the web run is an additional one Deflection roller 15 upstream.
  • the blowing nozzle 8 is already above the deflecting roller 15 arranged so that the blowing jet strikes the paper web 1 in the looping area, depending on the position of the blowing nozzle 18 even before the line of impact.
  • the airflow will due to the Coanda effect on both the pulley 15 and the pulley 2 diverted.
  • a suction box 16 is arranged next to the knife 7. He's with an endless, over Roll guided sieve belt 17 equipped, which is perpendicular to the plane of the direction Drawing revolves.
  • a blower 18 is connected on the suction side to the suction chamber 16, on the pressure side with the blow nozzle 8.
  • the embodiment 4 has the advantage that the air is essentially circulated becomes. In this way, the operator is annoyed by the Avoid air blasts.
  • a major advantage is that the cut Flag automatically caught by the circulating sieve belt 17 and then is fed to a collecting container.
