Method and apparatus for making absorbent structures having divided particulate zones

(57) Summary book invention offers the production method and equipment of absorption structure which have a discrete particulate absorbency material layer. This absorbency material layer is divided into two or the band beyond it (9) separated by the zone (11) which does not contain particulates substantially. The production method of such an absorption structure has a process which generates the initial particle suspension which was first suspended in the gas (for example, air) which flows through a inlet duct, and which has two phase fluid of absorbency gelling material particles. Subsequently, initial particle suspension is divided into much last particle suspension in many corresponding branch ducts. Each of the last particle suspension has the particles of a certain fixed rate as one function of the cross sectional area of a inlet duct. The particles of the last particle suspension are substantially distributed uniformly as one function of the cross section position of a branch duct. At the end, the suspended particles are filtered from the last particle suspension by capturing these on a support medium, for example, a tissue layer. The equipment by the present invention for enforcing the above-mentioned method, The particle suspension generator which has a relation into which the inlet duct and fluid for generating a inlet duct and initial particle suspension flow, It has the particle suspension divider arranged in for dividing into much last particle suspension a inlet duct, at least two branch ducts which have a relation into which fluid flows, and initial particle suspension in a branch duct a inlet duct. In the desirable enforcement form, this equipment is equipped with the adhesives let-off motion for covering the particles in the last particle suspension with adhesives, in order to form further the particles by which adhesives covering was carried out.
