Abstract
Track sections are attachedto the working face side of a face conveyor to form a track for a mining machine. The track sections have a rolled profile forming an L-shaped cross section with upright limbs pivotally interconnected at their ends by projecting sections of coupling plates facing the mine face to receive a chain link. A bead projects toward the mine face on the top of the upright limb to prevent collisions between the mining machine and the parts for pivotally interconnectng the track sections. The bead overlies the major part of an inclined surface of a transition section extending from the upright limb to a thickened lateral limb projecting toward the mine face for supporting the mining machine.
