Definitions

  • the invention relates to a machine according to the preamble of claim 1.
  • EP 0 492 310 A1 Such a machine is known from EP 0 492 310 A1.
  • the corrugated cardboard webs produced on such machines are between 1.2 and 2.8 m and usually 2.5 m wide. There are therefore considerable difficulties in achieving a uniform contact pressure over the full width of the corrugated cardboard web by the circulating endless pressure belt, since the deflection roller bends.
  • EP 0 492 310 A1 therefore provides for the deflection roller to be spherical in order to compensate for the deflection of the deflection roller. The effort for this is considerable.
  • the pressure band is subjected to torsional effects.
  • the replacement of a damaged pressure belt is extremely time-consuming and costly.
  • At least one deflecting roller is mounted in bearings, each of which can be displaced by means of a tensioning drive formed by a piston-cylinder drive.
  • the invention has for its object to develop a machine of the generic type so that the pressing of the liner to the corrugated paper web in the pressing area takes place in a particularly simple and reliable manner.
  • the at least one pressure belt is arranged essentially stationary in the machine, so it does not run around with the laminating web. This saves considerable design effort. Because the at least one pressure band is essentially stationary, the tensioning devices can be designed in a particularly simple manner. Adaptation to different widths of the corrugated cardboard web to be produced can also be implemented in a very simple manner.
  • the machine shown in FIGS. 1 to 3 has a machine frame 1 which has two mutually parallel, spaced-apart side walls 2, 3.
  • a lower corrugated roller 4 is rotatably supported in each case in a rocker 6 designed as a double lever by means of shaft journals 5.

  • the other end 61 of each rocker 59 is connected to the machine frame 1 via a feed drive 62.
  • These feed drives 62 are designed as hydraulically actuatable piston-cylinder drives, the cylinders 63 of which are pivotably mounted on the respective side wall 2 or 3, while their piston rod 64 acts on the end 61 of the respective rocker 59.
  • FIG. 6 shows a pressing device 52 ′ which is modified compared to FIGS. 4 and 5, in partial section. It also has a support bracket 53 which is provided with undercut grooves 65 running parallel to the axis of rotation 16. In these grooves 65, pressure segments 66 are fastened next to one another by means of fastening pins 67 with a T-shaped cross section.
  • the pressure segments 66 have a base plate 68 which is bent in the form of a part circle and to which the fastening pins 67 are attached.
  • a bellows-like pressure body 69 Arranged on the base plate 68 as a clamping device is a bellows-like pressure body 69 which has an inner pressure chamber 70 connected to a pressure connection 58 '.
  • a pressure band 71 is attached to the side of the elongated pressure body 69 facing the upper corrugating roller 13.
  • the pressure body 69 serving as a pressing element consists of an elastic material, for example rubber or the like. If its pressure chamber 70 is not pressurized, then the pressure belt 71, as shown in FIG. 6, is located on the left at a distance from the corrugation 20 of the upper corrugating roller 13. If, on the other hand, the pressure chambers 70 of the pressure body 69 are acted upon by pressure medium, then the pressure body 69 expands, as a result of which the pressure band 71 is advanced against the corrugation 20, as indicated in the center and right in FIG. 6.

  • the laminating web 75 is in the pressing device 31 or 52 or 52 'pressed firmly against the glued tips 74 of the corrugated paper web 72.
  • the pressure tapes 33 or the pressure tape 56 or the pressure tapes 71 exert the required contact pressure on the laminating web 75.
  • the laminating web 75 is preheated in the manner described and since the upper corrugating roller 13 is heated, on the way over the circumferential angle a on the upper corrugating roller 13 there is a fixed gluing between the laminating web 75 and the corrugated paper web 72.

If, in the embodiment according to FIGS. 4 and 5 or 6, the pressing device 52 or 52 'is removed from the machine, then the second preheating roller 42' is pivoted towards the upper corrugating roller 13 and acts as a pressing roller.
  • the pressure belts 33 and 71 can be controlled individually, i.e. each clamping device 35 or each pressure body 69 serving as a pressing element can be controlled individually. Basically, the contact pressure can be controlled as a function of the temperature of the incoming or outgoing liner web 75 in order to avoid excessive heating of the liner web 75.

If the width d of the paper web 72 and the liner web 75 is smaller than the length e of the upper corrugating roller 13, which is indicated in FIG. 1, then the pressure belts 33 that are not required become brought out of engagement with the corrugated roller 13 by not acting on their tensioning devices 35 in the position shown in broken lines in FIGS. 2 and 3.
  • the protrusion of pressure tapes 33 and 71 over the paper web 72 and laminating web 75 can be achieved by the adjustability of the support beam 37 carrying the tensioning devices 35 and a corresponding adjustability of the tape holder 32 in the direction 79 by half a width c of the pressure tapes 33.
  • the lateral protrusion of a pressure belt 33 or 71 over paper web 72 and the liner web 75 is smaller than half the width c if, in addition, the unneeded tensioning devices 35, 69 are not actuated.
