Abstract
An apparatus for use in producing a corrugated board product includes a flotation column for emitting pressurized air to support a traveling corrugated board product on a cushion of air void of contact with other surfaces at a point of warp detection. A warp detection apparatus is used in combination with the flotation column to analyze the supported traveling corrugated board product to permit adjustment of variables in a corrugated manufacturing system for corrected detected warp in the product.
Claims20
An apparatus for producing a corrugated board product, comprising:
- a flotation column having an outer surface, the outer surface comprising one or more openings;
- the flotation column being operable to support the corrugated board product at a variable height above the outer surface of the flotation column on a cushion of air that is emitted from the one or more openings in the outer surface of the flotation column;
- and
- a warp detection apparatus for detecting an amount of warp in the corrugated board product supported by the flotation column.
