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.

SUBSTANCE: method for producing a composite nonwoven sheet comprises: a stage of creating protrusions and depressions consisting in feeding the first sheet-shaped element to the engagement section between the first shaft and the second shaft and thus creating protrusions and depressions in the first sheet-shaped element; an intermediate stage of producing a semi-finished composite sheet by applying the second sheet-shaped element to the first sheet-shaped element and attaching the second sheet-shaped element to the portions of the first sheet-shaped element which correspond to the protrusions on the first shaft and thus forming a plurality of the first connected portions; and a coupling stage consisting in the use of the third shaft, the peripheral surface of which has protrusions and depressions, the shape of which is different from the shape of the protrusions and depressions of the first shaft, and forming the second connected portion on the semi-finished composite sheet. The second connected portion is formed in accordance with a model in which one first connected portion is connected to another first connected portion adjacent to it.

EFFECT: creation of composite sheets for absorbent products which have strength and excellent appearance.
