Abstract
A method and apparatus for producing fluff-free absorbent cores for absorbent sanitary articles, wherein loose unbound fibers and superabsorbent granular material dispersed in the loose unbound fibers are deposited on a movable surface and subsequently the fibers are mixed and bound together in such a way as to form an absorbent structure of bound fibers in which superabsorbent granular material is mixed and incorporated.
Claims7
A method for producing fluff-free absorbent cores for absorbent sanitary articles, comprising:
- depositing on a movable surface loose unbound fibers and superabsorbent granular material dispersed in said loose unbound fibers,
- mixing together said loose unbound fibers and the superabsorbent granular material deposited on said movable surface, and
- after said mixing step, binding together said loose unbound fibers so as to form an absorbent structure in which the loose unbound fibers are bound together, and the superabsorbent material is mixed and incorporated between the bound fibers,
- wherein binding together said loose unbound fibers is carried out by a thermal or mechanical process,
- wherein the movable surface includes a movable suction surface fluidly connected to a suction source, and
- wherein the loose unbound fibers are deposited by projecting the loose unbound fibers by pressurized air jets onto the movable suction surface fluidly connected to the suction source.
