DEVICE AND METHOD FOR MANUFACTURE OF NON-WOVEN MATERIAL OF TWISTED FIBERS Russian patent published in 2022 - IPC D04H1/50 

Abstract RU 2784502 C2

FIELD: textile industry.

SUBSTANCE: device for the manufacture of non-woven material of twisted continuous filaments contains at least one molding machine for formation of filaments and an air-permeable laying transporter for laying fibers in a laying area. In this case, behind the laying area in a direction of transportation of non-woven material, at least one preliminary strengthening device is located, and there is a suction device in the area of laying fibers, and/or in an area of the first preliminary strengthening device through the laying transporter, in the transportation direction, the second preliminary strengthening device is located. At the same time, there is a section between the first and the second preliminary strengthening devices, set so that there is no air suction, or there is less suction than in the area of laying fibers or in the area of the first preliminary strengthening device.

EFFECT: obtainment of non-woven material.
