A method and apparatus (20) for making an absorbent article can include a delivering of a first contoured web-strip (30a) from a first production supply (38) of contoured web-strip material, with the first contoured web-strip (30a) presenting a primary production sequence of side edge contours during its delivery. At least a second contoured web-strip (30b) can be delivered from a second production supply (40) of the contoured web-strip material, with the second contoured web-strip (30b) also presenting the primary production sequence of side edge contours during its delivery. In a particular aspect, the first and second contoured web-strips (30a and 30b) have been produced from a web (22) of absorbent material which has been divided to provided at least two web-strips (30) having a substantially nested configuration. In another aspect, the first web-strip (30a) provides a first orientation which presents a first sequence of side edge contours; and the second web-strip (30b) provides a longitudinally-reversed orientation which presents a different, substantially reversed sequence of side edge contours. In an additional aspect, the web-strips (30) have been separately stored to provide the first and second production supplies (38, 40) of contoured web-strip material.

A method and apparatus for forming an article (94) includes a moving of a forming surface (22) through an operative forming chamber (24) along a forming path length (40). A first fibrous stratum (26) of fiber material (96) can be deposited onto the forming surface (22), and the first fibrous stratum (26) can have a first stratum thickness (28). A first quantity of a first superabsorbent material (30) can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum (32) of fibrous material can be deposited to overlie the first fibrous stratum (26), and the second fibrous stratum (32) can have a second stratum thickness (34). A second superabsorbent material (36) can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.

An absorbent article includes a liquid pervious liner, a liquid impervious back sheet, and an absorbent composite located between the liner and the back sheet. The absorbent composite includes a first sheet, a second sheet, and a unitary absorbent core. The unitary absorbent core has a plurality of holes there through, wherein each hole has an area less than 200 mm2. The unitary absorbent core has a uniform density and is positioned between the first sheet and the second sheet. The first sheet is directly joined with the second sheet at a plurality of bond points. The bond points are located within the holes and are substantially devoid of absorbent material.

A disposable absorbent underpants for containing body fluid includes a first pair of leg elastics, a second pair of leg elastics, and a third pair of leg elastics. Each of the third pair of leg elastics is a distinct member containing at least one strand of elastic that is partially enclosed by a carrier sheet. Each of the third pair of leg elastics is separated from at least one of the first or the second pair of leg elastics by a gap.

An apparatus and process for directing particulate material (22) into a moving gas stream includes a delivering of the particulate material (22) from a particulate reservoir (24) along a delivery direction (118) into a housing (30) having a housing axis (32). A housing gas flow is introduced into the housing (30) through at least one entry gas port (40) that has been provided in the housing (30). The housing gas flow is arranged to combine with the particulate material (22) that is delivered from the particulate reservoir (24). A swirling motion is imparted to the housing gas flow, and the swirling motion has at least a rotational component (110) of movement which is directed substantially circumferentially about the housing axis (32).

A method and apparatus for forming an airlaid fibrous web on a moving surface can include a contoured foraminous member (62) having a first side portion (66), a laterally opposed second side portion (68), and a depth contour. A longitudinally extending, first side-masking member (52) can be located superjacent the first side portion (66) of the foraminous member (62), and can have a first inboard side wall surface (70). At least a second, separately provided, longitudinally extending, side-masking member (53) can be located superjacent the second side portion (68) of the foraminous member (62), and can have a second inboard side wall surface (72). Either or both of the first and second side-masking members (52, 54) are at least laterally movable relative to the foraminous member (62). A releasable attachment system (74) can selectively hold at least the first side-masking member (52) at a substantially fixed position relative to the foraminous member (62).

An absorbent structure can include a matrix of fibers, wherein the matrix is reinforced with a reinforcing member, such as scrim. The scrim is secured to the fibrous matrix by entanglement of fibers with the scrim and entanglement of fibers in the matrix from opposite sides of the scrim with each other. The scrim layer can be restricted to a longitudinally extending, medial region of the absorbent. In a particular arrangement, the scrim has a cross-directional width dimension which is less than a narrowest width dimension of the fibrous matrix. The scrim can be located between two, opposed, major surfaces of the fibrous matrix. The scrim has a reduced stiffness in the cross direction which promotes fit and comfort of the absorbent structure as incorporated into a disposable absorbent garment.

Process and apparatus for air forming an article having a plurality of superimposed fibrous layers. The layers are formed in substantially discrete forming chambers by depositing fibrous material on a forming surface which moves along an arcuate path through the chambers. A first layer is air-formed on the forming surface as the surface moves through the first forming chamber and a second layer is air-formed over the first layer as the surface moves through the second forming chamber.

A method and apparatus (20) for forming a fibrous web (50) includes a movable, foraminous forming surface (22) and a substantially stationary, vacuum-commutator duct system (24) which is located substantially subjacent the forming surface (22). The vacuum-commutator duct system (24) has an entrance opening (26) that changes in configuration along a longitudinal dimension (30) of the entrance opening (26).

Absorbent structures are disclosed which may be incorporated into liquid absorbent products, such as diapers, adult incontinence products, feminine hygiene products, and the like. The absorbent structures are made from a fibrous material and include a pair of opposing lateral flaps. The lateral flaps are folded onto the fibrous web. By folding the lateral flaps onto the fibrous web, greater basis weight areas may be formed on the absorbent structure. By varying the width of the lateral flaps, the basis weight differential may be increased and decreased. The lateral flaps also form the widest portion of the web material for facilitating folding during a continuous process.
