Device on a spinning preparation machine, in particular carding machines, carding machines or the like, for detecting carding process variables

摘要

In a device on a spinning preparation machine, in particular carding, carding o. The like., In which a garnished, fast-rotating roller is at least opposite a garnished component, the component is associated with a piezoelectric sensor touching, which is connected to an electrical evaluation, which with a display - And / or switching device is in communication. In order to enable detection of the intensity of the contact between fibers and the fiber-guiding clothing of the component (carding intensity) in a structurally simple manner, the piezoelectric sensor is a structure-borne sound sensor of high sensitivity and the electrical evaluation device from the structure-borne sound can determine the intensity of the contact between the fibers and the fiber-guiding contact Set the component (carding intensity) to determine.
