Corrugated Pizza Box and Method for Production of Same
20240317476 · 2024-09-26 ·

A corrugated pizza box is made using a web fed rotary die cutter with the web produced by a corrugator singlefacer that is speed synchronized with the rotary die cutter. The singlefacer produces SemiCorr Singleface Board (SSB) made possible by special corrugating rolls that allow a bottom liner to be bonded to a fluted and creased medium or liner within the singlefacer. This medium or liner has cross flute bond lines that provide in-line stiffness to the two-ply board exiting the singlefacer.

Method and system for producing a three-dimensionally deformed plate

A method for manufacturing a three-dimensionally deformed plate made of a wood fiber material comprises providing a prefabricated, flat wood fiber material plate as the original plate, preheating the original plate in sections, wetting the preheated section of the original plate with an atomized liquid mixture of water and a separating agent, introducing a section of the original plate that is preheated and wetted with a liquid mixture of water and a separating agent between two rollers of a molding station, wherein the rollers respectively provide a corrugated profile in the peripheral direction of the external surface, such that the original plate is being deformed in sections into a plate with a wave shape, wherein rollers are being used, the respective profiling of which has half-waves which follow one another in the peripheral direction and which at least partially have a different extension in the peripheral direction.

HEATING DEVICE, COMPRISING TWO PRECEDING ARCUATE HOT PLATES, OF A TWO-SIDED MACHINE
20180104925 · 2018-04-19 ·

A heating device of a two-sided machine has a stand which has a first arcuate hot plate and a wall on which a sleeve is provided. A second arcuate hot plate is arranged above the first arcuate hot plate. The second arcuate hot plate is connected to the sleeve by a connecting stem. The stand includes a cylinder unit, the piston rod of which is connected to the trailing end of the second arcuate hot plate. A second corrugated-cardboard ply and a first corrugated-cardboard ply are guided so as to run between the hot plates, whereas a third corrugated-cardboard ply is guided so as to run, above the second arcuate hot plate, through the second arcuate hot plate. The second arcuate hot plate is lowered by the cylinder unit in order to be placed in connection with the second corrugated-cardboard ply.
