An absorbent core includes a width, a length, an elongate liquid holding formation and an outer region of fibrous material located outward of the liquid holding formation. The outer region of the absorbent core has, in cross-section taken across the width of the absorbent core, a first thickness. The liquid holding formation has, in cross-section taken across the width of the absorbent core, second and third thicknesses. The second and third thicknesses of the liquid holding formation are greater than the first thickness of the outer region.

Absorbent core with an elongate liquid holding formation

An absorbent core comprises an elongate liquid holding formation with a peripheral edge. The liquid holding formation has a surface formed with at least one channel extending longitudinally in the core for distributing liquid lengthwise along the core. The channel has longitudinally opposite ends spaced longitudinally inward from the peripheral edge of the liquid holding formation to inhibit the flow of liquid in the channels past the peripheral edge of the liquid holding formation.

Absorbent core with elongate liquid holding formation

Apparatus for forming an air formed fibrous web has a form member on which fluent fibrous material is deposited in an air formed deposition process. The fibrous web may be used as an absorbent core of an absorbent article. The form member has a forming surface with a pocket for making a thicker portion of the fibrous web such as for a liquid holding formation of the absorbent core. The pocket has a bottom surface which is shaped so that additional material will be deposited in the pocket. A form member and an absorbent core made using the apparatus are also disclosed.

Apparatus and form for making an air formed fibrous web

An apparatus and process for directing particulate material ( ) into a moving gas stream includes a delivering of the particulate material ( ) from a particulate reservoir ( ) along a delivery direction ( ) into a housing ( ) having a housing axis ( ). A housing gas flow is introduced into the housing ( ) through at least one entry gas port ( ) that has been provided in the housing ( ). The housing gas flow is arranged to combine with the particulate material ( ) that is delivered from the particulate reservoir ( ). A swirling motion is imparted to the housing gas flow, and the swirling motion has at least a rotational component ( ) of movement which is directed substantially circumferentially about the housing axis ( ).
