Abstract
In an apparatus on a carding machine for grinding a fiber processing clothing on a roller or a card flat, grinding equipment includes at least one grinding element and an infeed device serving to position the grinding element against the clothing. To permit reliable detection and monitoring of the contact between the at least one grinding element and the clothing in a simple manner, a structure-borne noise sensor is associated with the grinding equipment and an electronic evaluator is capable of determining from the structure-borne noise the intensity of the contact between the at least one grinding element and the clothing.
Claims25
An apparatus on a carding machine for grinding a fibre processing clothing that is arranged on a rotating roller or a card flat, comprising:
- grinding equipment with at least one grinding element;
- an infeed device serving to bias the grinding element into contact with the clothing at a contact pressure;
- a structure-borne noise sensor associated with the grinding equipment;
- and
- an electronic evaluator adapted to control the infeed device to adjust the contact pressure between the grinding element and the clothing based on an intensity level of structure-borne noise detected by the structure-borne noise sensor.
