Abstract:

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

Abstract:

A method is provided for making absorbent pads that may have a longitudinally asymmetric shape. The pads may be used in various consumer absorbent articles. The method includes delivering a supply of an absorbent web material in a machine-direction and cutting the absorbent web material in a cross-direction to form a repeating nested pattern of generally identically shaped and oppositely oriented absorbent pads, the pads being disposed longitudinally in the cross-direction of the absorbent web. The pads are longitudinally asymmetric and nested such that the crotch portion of one pad is oriented towards the back portions of immediately adjacent pads, and adjacent nested pads share defining cut lines such that there is no wastage of absorbent web material between the nested pads.

Abstract:

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.

Abstract:

In a process and apparatus for making a reinforced fibrous absorbent member, fibrous material is collected on a forming surface to at least partially form the absorbent member. Fibrous material is entangled with a reinforcing web which is overlaid on at least a portion of the partially formed absorbent member. Additional fibrous material is collected on the forming surface to further form the absorbent member whereby at least a portion of the fibrous material forming the absorbent member becomes entangled with at least one of the reinforcing web and the fibrous material entangled with the reinforcing web to secure the reinforcing web within the absorbent member.

A source of reinforcing web is disposed exteriorly of the forming chamber. A delivery tube has an inlet end open to the forming chamber exterior, a discharge end open to the forming chamber interior, and a central passage extending between the inlet end and the discharge end. At least a portion of the delivery tube adjacent the discharge end extends within the forming chamber interior. The delivery tube is arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of the tube at the inlet end and for guiding the web to the discharge end for conveyance within the forming chamber toward the forming surface.

Abstract:

Apparatus for making a reinforced absorbent member includes a forming chamber adapted to contain a fluent fibrous material. A forming surface is moveable within the forming chamber along an arcuate path generally from an entrance of the forming chamber to an exit thereof. The forming surface is adapted to collect fibrous material thereon to form the absorbent member. A source of reinforcing web is disposed generally exterior of the forming chamber. The forming chamber has an opening through which the reinforcing web is received into the forming chamber for subsequent conveyance within the forming chamber toward the forming surface. The opening is disposed downstream of the forming chamber entrance generally in the direction of movement of the forming surface along the path.
