Claims27
A method of manufacturing an elastic laminate for a disposable absorbent hygiene product, said elastic laminate comprising at least a first continuous sheet and at least one elastic strand, said method comprising:
- advancing said first continuous sheet having a first surface in a machine direction (M), and defining a width in a cross-machine direction;
- advancing said at least one elastic strand in the machine direction (M) in a stretched state;
- dispensing a liquid adhesive onto said at least one elastic strand from a nozzle comprising at least one liquid discharge passage;
- and
- blowing air onto said at least one elastic strand from an air blowing device, said air blowing device being arranged at a predetermined distance (D1) upstream from said nozzle before said liquid adhesive is dispensed onto said at least one elastic strand in order to blow off dust, loose fibers or other contaminants,
- wherein said air blowing device is a separate device from said nozzle.
An apparatus for manufacturing an elastic laminate for a disposable absorbent hygiene product, said elastic laminate comprising at least a first continuous sheet and at least one elastic strand, said apparatus comprising:
- a first feeding device configured to continuously advancing said first continuous sheet having a first surface in a machine direction (M), and defining a width in a cross-machine direction;
- a second feeding device configured to continuously advancing at least one elastic strand in the machine direction (M) in a stretched state;
- a nozzle having at least one liquid discharge passage to dispense a liquid adhesive onto said at least one elastic strand;
- and
- an air blowing device arranged at a predetermined distance (D1) upstream from said nozzle so that said air blowing device blows air onto said at least one elastic strand before said liquid adhesive is dispensed onto said at least one elastic strand,
- wherein said air blowing device is a separate device from said nozzle.
