Abstract: An apparatus is provided on a spinning preparation machine for adjusting the carding clearance. A clothed roller has a cylindrical peripheral surface and a cladding facing and spaced therefrom, wherein between the peripheral surface of the roller and a part of the cladding there is a carding region with a carding clearance where carding work is performed and carding heat is generated, heat leading to an alteration across the width of the machine in the contour of at least one of the components lying opposite each other. In order in simple manner to allow a uniform carding clearance under different production and processing conditions, the carding clearance can be made smaller by external energy input to at least one of the components facing each other and/or can be enlarged by throttling the energy input and the energy input.
