The grinding device is constructed with a grinding member which is biased elastically against the teeth of the clothing of a carding machine during operation of the machine. During grinding, the grinding member is capable of three degrees of freedom of movement under the elastic biasing force. In one embodiment, individual grinding stones are used as the grinding members. In another embodiment, an elongated flexible belt having a grinding coating is used as the grinding member and is biased by means of a tube containing pressurized fluid.
