An apparatus for bonding textile sheet-like structures is disclosed. In the bonding of textile sheet-like structures (10, 11) it is very important, especially in the case of sensitive fabrics, to accurately control the pressure which is exerted. In conventional apparatuses of this kind, in which the pressure roller (23) and the contact roller (24) have an essentially -solid sleeve, this pressure is difficult to control because the thickness of the sheet-like structures (10, 11) which are to be processed varies. This results in pressures which are either too high or too low so that either the bonding is insufficient or the outer appearance of the sheet-like structures (10, 11) which are to be bonded is impeded. In order to avoid these disadvantages, the pressure roller (23) of the apparatus according to the invention has a tubular sleeve (26) which is resiliently deformable and which is subjectable to compressed air from a cavity (37) inside the pressure roller (23). As a result, the sleeve (26) always exerts a pressure on the sheet-like structures (10, 11) to be bonded which corresponds to the inner pressure in the cavity (37), without being affected by the thickness of the sheet-like structures (10, 11) or other influences. The apparatus according to the invention is particularly suitable for bonding outer fabrics made of (synthetic) micro-fibres with interlinings.
