Definition
Meaning
A container or chamber that receives and distributes pulp slurry at the start of the paper machine.
In paper manufacturing, the headbox is a critical component that ensures uniform flow and distribution of fiber suspension onto the forming wire; metaphorically, it can refer to any initial distribution chamber in fluid systems.

FAQ
Frequently Asked Questions
No, it is a highly specialized technical term used almost exclusively within the pulp and paper manufacturing industry.
In industry jargon, it can be verbalised to mean 'to process or control via the headbox,' but this is not standard English.
A headbox is specific to paper machines. A 'header' is a general engineering term for a pipe or chamber that distributes fluid to multiple smaller pipes.
Rarely. It is overwhelmingly associated with papermaking, though similar distribution chambers in other fluid processes might be referred to analogously.
