Abstract

The present invention relates to an arrangement for manufacturing spunlace material, comprising a forming station (1) and an entangling station (2), wherein the forming station includes a first fibre former (6) for air-laying staple fibres, and a second fibre former (7) for air-laying short fibres on an underlying forming wire (8), on which the air-laid fibres are retained with the aid of a subpressure created in a suction box (15) positioned beneath the forming wire and with the aid of which the formed mat of fibres is transported to the entangling station (2). According to the invention, at least one screening element (16) is arranged beneath the fibre former (7) for short fibres such as to screen-off the subpressure and therewith create one or more regions on the forming wire on which no short fibres will be laid when the forming wire passes the fibre former (7) for short fibres. The invention also relates to a method for manufacturing spunlace material and to an absorbent, disposable article which includes such spunlace material.

INVENTOR T .BILLGREN, KULLAVIK, J .HELLSTRoM, GoTEBORG (30) PRIORITY DETAILS (54) USING PROCEDURES AND DEVICES FOR MANUFACTURING A SPUNLAC MATERIAL AND ABSORBING SINGLE SUMMARY) manufacture spunlace material comprising a forming station and a entangling station, which forming station comprises a first fiber former (6) for air-laying staple fibers (S) and a second fiber former (7) for air-laying short fibers (P) p4 an underlying forming wire (8) , on which the air-laid fibers are retained by means of the negative pressure in a suction cup (15) arranged under the forming wire and by means of which the formed carpet of fibers is transported to the entangling station (2). According to the invention Kr shielding elements (16) are arranged below the fiber former (7) for short fibers to create, by shielding the negative pressure, one or more circumferential 1:14 forming wire, pit which no debugging of short fibers takes place when the forming wire passes the fiber former for short fibers. The invention further relates to a method of making spunlac material and to an absorbent angel article comprising such spunlac material.
