In a mineral-mining cutter chain the links between cutter tool holders are so shaped, being preferably of T-shaped cross section, that the face of a link on the same side of the chain as the cutters extends laterally of the rest of the link to seal of the chain guide slot in the vicinity of the link to prevent entry of dirt into the slot. |
