Definitions

  • the invention relates to a method for heating a moving Web, in particular corrugated board web according to the preamble of the claim 1 and a preheater according to the preamble of Claim 5.
  • a preheater for a corrugated cardboard web is from DE 23 02 449 known.
  • This known preheater has a rotatably driven one Heating drum.
  • the web is over a fixed inlet fed to the heating drum and from it via a fixed space Process carried away.
  • the heating drum is a deflection roller for the Assigned path that is concentric around the central axis of the heating drum is pivotable.
  • the swivel angle determines the contact surface the web on the heating drum and thus the one to be transferred Amount of heat.
  • the swiveled deflection roller takes the web with and moves them over the heating drum, taking the wrap angle is adjustable. The heat is transferred from the Heating surface of the drum in the adjacent outer layer of the web.
  • a second roller is provided. These rollers have For safety reasons, a distance of 120 mm from the rotating heating drum.
  • the disadvantage is that the web only with the heating drum can loop around a maximum angle of approx. 270 °. Further the web is only heated on one side by the heating drum, whereby the web heats up unevenly. Also exists the risk that at higher web speeds the subsequent Glue applied glue due to the only one-sided Railway heating does not start up quickly enough, i.e. a certain adhesive effect unfolds.
  • From US-A-5 156 714 is a corrugated cardboard machine for manufacturing a one-sided corrugated cardboard known in which the incoming smooth path through the S-shaped looping of two heated Rolling is heated on both sides. The incoming second, later The web to be grooved is passed over a heating surface, the effective heating surface by adjusting a deflection roller for the track is adjustable. However, only the heating takes place here an outside of the web. This is then done using conditioned in a steam chamber.
  • the invention lies Object of the task, a method and an apparatus for both sides Heating a moving web, especially a corrugated board web to create, with a small footprint and small Construction work allows the adjustability of the effective heating surfaces becomes.
  • the invention eliminates between deflection rollers and heating drum the danger of moving in, so that the legally prescribed safety distance of the deflecting roller to the heating drum is.
  • the effective heating surface according to the invention increased with reduced space requirements and reduced effort.
  • the possible control range for heat transfer expanded. Also the maximum wrap angle the heating drum can be enlarged by the web.
  • a circular segment Heating surface assigned with the deflection roller is connected so that it moves concentrically to the heating drum can be, with the circular segment-shaped heating surface other side of the web is guided.
  • the preheater 1 has a heated drum 2 with a smooth surface. This can e.g. through steam or be heated inside in some other way.
  • the drum 2 can be driven in the direction of the arrow. But it can only be rotatably mounted.
  • the drum jacket 3 is good thermally conductive material, preferably made of steel.
  • the drum 2 is stored on both sides in bearing plates 4.
  • Lane 5 e.g. a cover sheet for a one-sided corrugated cardboard sheet, runs over a feed 7 which e.g. as a fixed pair of rollers is formed, the drum 2 in the indicated direction of the arrow to.
  • the web 5 lies on the heated drum jacket 3 and wraps it around with the smallest possible wrap angle, e.g. 72 °.
  • the web 5 runs out over a deflection surface 10, e.g. a rotatable deflection roller 11, guided. From the roller 11 runs Lane 5 continues to a fixed discharge 12.
  • a deflection surface e.g. a rotatable deflection roller 11, guided.
  • Lane 5 continues to a fixed discharge 12.
  • the web 5 e.g. a single-sided corrugated cardboard machine 20 to.
  • the guide roller 21 can cooperate with the pressure roller 22.
  • the corrugated roller 23 acts as usual together, on the corrugated paper web 24, the glue transfer roller 25 transfers the glue from the gluing unit, not shown, which is arranged to a foot 17 with insertion guide 18 is.
  • the outlet 12 can also be in another Be trained.
  • a heating surface 13 is connected to the deflection surface 10 is formed by a heatable circular segment 14 made of metal, which is arranged concentrically to the central axis of the drum 2 is.
  • the heating surface 13 and in the specific embodiment as Deflection roller 11 formed deflection surface 10 are together around the Center axis of the drum 2 is pivotally arranged.
  • the deflection roller 10 and the heating surface 13 on circular, 2 rotatable disks about the central axis of the heating drum 30 which can be fastened by means of an adjusting device, e.g. are adjustable by means of chains.
  • the deflection roller 11 with heating surface 13 is in a position with the smallest wrap angle, e.g. 72 °.
  • the Lane 5 does not run over the heating surface 13.
  • the corrugated web 7 ' also the other outside the web (in the case of a one-sided corrugated cardboard web, the level Web 6) are heated, as can be seen from FIG. 2, the Deflection surface 10 with the heating surface 13 clockwise around the Center axis of the drum 2 pivoted.
  • the size of the swivel angle depends on the heat to be transferred into the web 5 from.
  • the swivel angle can be done manually or automatically, e.g. dependent of web moisture, web temperature and / or web speed, can be set.
  • the maximum swivel angle is determined by the approaching path 5 limited.
  • the heating surface 13 can with meandering heating channels 15 or electrical heating wires. Through the heating channels a hot medium, e.g. a heating steam can be led.
  • a hot medium e.g. a heating steam
  • the roller 11 is rotatable as a deflecting surface 10. If necessary, also be driven.
  • the detachable foot 17 of the side bearing plates 4 is possible close to the imaginary circular path of the segment 14 arranged.
  • the foot 17 can e.g. one directly below it insertable glue mechanism 17 or the like, not shown record, tape. So that the heated drum 2 and Heating surface 13 very close to the glue transfer point on the circumference of the Glue application roller 25 are positioned. This will be a unnecessary heat loss during the movement of the web 5 from the preheater 1 avoided to the glue transfer point. The space requirement will be decreased.
