Abstract

1381760 Mines &c RHEINSTAHL AG 28 Nov 1972 [1 Dec 1971] 54995/72 Heading E1F A lagging mat, suitable for forepoling comprises longitudinal and transverse wires, the transverse wires 3, 6 (Fig. 4) at one end of the mat being located in bends 5 in the longitudinal wires and the ends 2 of the longitudinal wires at the other end of the mat being bent into a U shape. Longitudinally adjacent mats 1, 4 are linked together by passing the ends 2 of the mat 1 between the wires 3, 6 of the mat 4. The leading mat 1 is held as a cantilever for forepoling by bending the ends 2 of the longitudinal wires at the edge of the mat to the rear by means of a tool 7 (Fig. 7).
