Claim Text:
1. A device for bonding a web-shaped textile product having thermally fusible fibers that are fused during a bonding process by hot gases, comprising a drum that is rotatably mounted within a treating chamber to which hot air is supplied, said drum comprising a gas-permeable circumferential surface having a plurality of openings to provide gas-permeability, the drum being configured to be partly wrapped during use by the web-shaped textile product to be bonded a suction unit which is paired with the drum and by which the drum is placed under suction such that the hot air flows out of the treating chamber through the web-shaped textile product to be bonded during the bonding process; a heater for heating air that is supplied to the treating chamber and flows out of the treating chamber through the web-shaped textile product to be bonded; and a structured lining having a plurality of openings defining a regularly distributed pattern of geometric shapes configured to emboss the web-shaped textile product by the hot air flowing through the web-shaped product, the structured lining being wound onto the gas-permeable circumferential surface, said openings in the gas-permeable circumferential surface of the drum having a diameter smaller than 8 mm, and the openings in the structuring lining having a diameter larger than 8 mm, wherein the suction in the drum and the temperature of the hot air inside the treatment chamber have values selected to cause the material web to be patterned by the openings in the structured lining during the bonding process.
