摘要:
The plant includes a single facer for the production of a corrugated board. Video cameras detect any gluing defects or other defects of the corrugated cardboard. An image processing unit and a central control unit provide information about the detected defects and can act on one or more operating parameters of the plant.

A heating device of a two-sided machine (9) has a frame (1) that has a first arcuate hot plate (2) and a wall (3) on which there is provided a sleeve (4). A second arcuate hot plate (5) is arranged above the first arcuate hot plate (2), the second arcuate hot plate (5) being connected to the sleeve (4) via a connection shaft. The frame (1) comprises a cylinder unit (6) whose piston rod is connected to the rear end of the second arcuate hot plate (5). A second corrugated fiberboard layer (11) and a first corrugated fiberboard layer (12) are guided so as to run between the hot plates (5, 2), while a third corrugated fiberboard layer (10) is guided so as to run above the second arcuate hot plate (5), through the second arcuate hot plate (5). The second arcuate hot plate (5) is lowered by the cylinder unit (6) so as to be in contact with the second corrugated fiberboard layer (11).

Eine Wellpappe-Anlage zur Herstellung von Wellpappe umfasst eine Materialbahn-Abgabevorrichtung (30) zum Abgeben einer Materialbahn (36), eine Fördervorrichtung zum Fördern der Materialbahn (36) entlang einer Materialbahn-Förderstrecke (44), eine der Materialbahn-Abgabevorrichtung (30) nachgeordnete Druckvorrichtung (37) zum Erzeugen von mindestens einem Druckbereich auf der Materialbahn (36), eine der Druckvorrichtung (37) nachgeordnete Druckbereich-Trocknungsanordnung (40) zum Trocknen des mindestens einen Druckbereichs und eine der Druckbereich-Trocknungsanordnung (40) nachgeordnete Verbindungsvorrichtung (70) zum Verbinden der bedruckten Materialbahn (36) mit mindestens einer weiteren Materialbahn (22) zum Erzeugen einer mindestens einseitig kaschierten, bedruckten Wellpappebahn (75). Ein Trocknungsbeginn des mindestens einen auf die Materialbahn (36) aufgebrachten Druckbereichs ist durch die Druckbereich-Trocknungsanordnung (40) beeinflussbar.
摘要:
Equipment for controlling manufacture of corrugated cardboard, including: a sensor arrangement arranged to measure moisture of a liner in connection with unwinding of the liner in an unwinding part in order to control the moisture of the liner prior to gluing to a fluting on the basis of the measured moisture.
摘要:
A machine for producing corrugated paperboard which includes: an endless fluted conveyor belt assembly having an endless fluted conveyor belt including a plurality of adjacent flutes thereon wherein the flutes are configured to correspond to the teeth on a corrugating roller which is located at the upstream end of the endless fluted conveyor assembly; at least one source of electromagnetic radiation and associated support surface located downstream of a glue applicator, said associated support surface also being sufficiently proximate to the flutes on the endless fluted conveyor belt, so as in use, to be capable of at least partially holding newly glued planar sheet and corrugated sheet material together; and wherein the machine further includes an industrial inkjet printer which is positioned to print a planar liner sheet prior to the liner sheet being bonded to a corrugated sheet material.
摘要:
A single facer including a preheater (28) for conditioning a paperboard web (24). The preheater (28) is positioned upstream from the corrugating nip and includes an arcuate surface (26) facing the web. A plurality of primary channels (82) are disposed internally within the preheater (28) in thermal communication with the arcuate surface (26). High pressure steam is supplied to the primary channels (82) for heating the arcuate surface. A plurality of outlet ports (98) extend within the preheater (28) and are in fluid communication with the heated arcuate surface (26). Low pressure steam is released through the plurality of outlet ports (98) thereby producing a steam film between the heated arcuate surface (26) and the paperboard web.
摘要:
An apparatus and related method for forming a double face paperboard web (24) are disclosed. The apparatus of the present invention includes a heating section (12) that includes at least one heating plate (16) having an upper surface facing a paperboard web and heated by a plurality of primary channels (38) supplied with steam. Steam supplied to secondary channels (50) exits through outlet ports (54) thereby producing a steam film between the upper surface of the heating plate and the lower surface of the paperboard web. The steam film substantially reduces frictional forces opposing movement of the web while also dramatically increasing the heat transfer to the paperboard web (24) and accelerating the gelatinization of the glue therein. A plurality of fluid ports are formed within a weight blanket for producing a steam film (60) between the weight blanket and the web for, again, reducing frictional contact with the web while improving heat transfer thereto.
