| 摘要 |
The invention relates to a face accessory, in particular machine tracks (1) or guide shelves for winning machines in underground mining, which is detachably fastened to the side wall (3) of a face conveyor (4) and is provided at both section ends with complementary projections (5, 9) and recesses (7, 8). The projections (5, 9), which jut beyond the section length of the conveying troughs (4) and engage in a positive-locking manner in corresponding recesses (7, 8) of the adjacent sections of the machine track, are designed in such a way that they form a tension-proof connection transmitting longitudinal and transverse forces. <IMAGE>
