摘要

A device to a carder or carding machine for grinding a fiber-processing set (14a) disposed on a rotating drum or a lid, comprises a grinding device (20) with at least one grinding element (24) and for delivery of at least one grinding element (24) against the grain processing set (14a) serving advancing, with the degree of service; and the grinding intensity are recognizable. The grinding device (20) is a structure-borne noise sensor (27 2, 27 3) associated with, and an electronic evaluation unit is capable of a signal from the body sound sensor (27 2, 27 3) the intensity of the contact between the at least one grinding element (24) and the fiber-processing set ( 14a) to determine.
