Airlaid Forming Head Design and Fibre Distribution
topic
Airlaid forming heads individualise and transport fibres using high-velocity air flow through a series of rotating beater bars, distributing fibres uniformly across the collection screen width through precisely designed air flow channels and fibre distribution plates, with forming head geometry and rotational speed governing the uniformity of fibre deposition across the full web width from 1 to 3.5 metres at production speeds of 50 to 300 metres per minute.
Role
Determines the cross-direction web weight uniformity and through-thickness fibre distribution quality that are the primary structural parameters of airlaid nonwovens, with forming head design being the most critical machine element whose fibre distribution capability governs whether the airlaid web achieves the weight uniformity and three-dimensional isotropic structure required for high-performance absorbent product applications.
