SUBJECTED TO JET JOINT LAMINAR SHEET HAVING HOLLOW PROJECTIONS, AND METHOD AND APPARATUS FOR PRODUCTION THEREOF Russian patent published in 2016 - IPC D04H1/492 

FIELD: hygiene.

SUBSTANCE: present invention is aimed at the laminar sheet subjected to jet joint, a method and a device for its formation, as well as final applications of the laminar sheet subjected to jet joint. Laminar sheet comprises a support layer and nonwoven sheet with projections, having multiple ledges, which preferably are hollow. As a result of jet joint jointing fluid medium is directed through the support layer and inside the sheet with projections, which is located on the forming surface. Force action of jointing fluid medium leads to a compound of two layers with each other and fluid medium leads to indentation of the part of fibres in the sheet with protrusions in the holes located on the forming surface, forming hollow projections.

EFFECT: laminar article obtained as a result has multiple applications, including without limitation the materials for wet and dry tissues, as well as inclusion of the absorbent products of personal hygiene in the different parts and use in package, where control of fluid medium is a problem.
