Device for bonding textile products by means of hot gases

FIELD: textile and paper.

SUBSTANCE: invention relates to a device for bonding web-shaped textile products by means of hot gases, in particular for bonding a nonwoven fabric, that has thermally fusible fibres and/or filaments, comprising a drum that is rotatably mounted within a treating chamber to which hot air is supplied, said drum comprising a circumferential surface which is designed to be gas-permeable by means of a plurality of openings and which is partly looped by web to be bonded; suction unit which is paired with drum and by means of which drum is placed under suction such that hot air flows out of treating chamber through material web to be bonded; and a heater for heating air that is conducted out of drum; and includes a structured lining that embosses textile product by means of a plurality of openings during bonding process is wound onto drum circumferential surface that is designed to be gas-permeable, said openings being larger than openings in drum circumferential surface that is designed to be gas-permeable.

EFFECT: disclosed is a device for bonding non-woven material.

SUBSTANCE: described aerodynamic embossing devices use cylindrical rotary masks with air pikes arranged therein to direct air flow through the mask holes onto the material surface to be embossed. The said devices comprise also at least one mask stabiliser arranged in the said device so that to apply a force to the mask sufficient to reduce that gap between the material and the mask area facing the material in close proximity to the material during the mask revolution.

EFFECT: high quality of high-resolution embossed images, reduced amount of poor areas and high uniformity across embossed material width.
