摘要： An apparatus for scarfing a fibrous web includes a rotatable scarfing roll with vacuum ports and an air moving source in fluid communication with the vacuum ports. The rotatable scarfing roll has a core member which includes a plurality of scarfing elements connected thereto and vacuum ports located therein. A method for scarfing a fibrous web includes providing a rotatable scarfing roll with vacuum ports and reducing scarfing wind by applying vacuum to the vacuum ports. A method for producing absorbent articles includes providing a fibrous web, contacting the fibrous web with a rotatable scarfing roll with vacuum ports to remove a portion of the fibrous web, applying vacuum to the vacuum ports to reduce scarfing wind, and producing an absorbent article with the fibrous web.

摘要： 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).

摘要： 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).
