- corrugated board it is a typical feature of the corrugated board presented, at least one with two smooth paper webs on both sides closed or covered wave web having corrugated board, that the corrugated board or the corrugated board is relatively dimensionally stable. Under dimensionally stable is to be understood that the corrugated board as such is non-flexible or Ibrmstabil, so they can not be wound without destroying the W'cllcn Modell and is only slightly bendable or bendable.
- the longitudinal cutting device and the transverse cutting device of the generic generation systems are provided separately from one another.
- a corrugated board production plant of the known type comprises the usual sections of the plant with known machine stations and aggregates.
- a corrugated paper web is produced under pressure and heat. Glued tip tips are glued to ceiling panels.
- the result is a single-walled corrugated cardboard.
- multi-corrugated, in particular two- and three-wave corrugated boards are produced.
- the single or multi-wall corrugated cardboard is dried in the so-called heating and drawing section. After leaving the heating and drawing section, the corrugated board web is cut into desired formats of specified format width and length.
