摘要

An apparatus on a spinning preparation machine, especially a flat card, roller card, cleaner or the like, with a cooling system, a roller has a cylindrical peripheral surface and a casing opposite to and spaced from this peripheral surface, a carding region where carding work is carried out and heat is generated being present between the peripheral surface of the roller and a part of the casing. A cooling medium enters the interior void space of the roller, passes through and exits again. In order to reduce or avoid thermal expansion of the roller in a structurally simple manner, the cooling medium is a cooling gas, especially air, which is capable of absorbing heat in the interior void space of the roller and dissipating it from the interior void space of the roller.
