ABSTRACT:
An apparatus on a spinning preparation machine for monitoring and/or adjusting clearances at components has a clothed, high-speed roller located facing at least one clothed and/or unclothed component and the clearance between the components facing one another is alterable. The roller and opposed component(s) are electrically isolated with respect to one another and are connected as contact elements to an electrical power supply line in which a measuring device for ascertaining contact is located. In order to avoid an undesirably heavy contact between the components, electric signals are emitted upon contacts with the clothing of the roller and the measuring device is arranged quantitatively to determine the contacts.
