Nato¬ miast w chwili usytuowania maszyny urabiajacej przed jak i na wprost sekcji, oslony (3) sa odchy¬ lane, aby maszyna mogla przejsc przed sekcja. Ruch plyty dociskowej (3) za pomoca silowników (4 i 5) sterowany jest recznie luib automatycznie. Obudo¬ wa ta calkowicie zabezpiecza urabiany ocios wy¬ robiska przed obwalami oraz uriiiemozlliiwia zasypa¬ nie przedzialu roboczego, a tym samym gwarantuje bezpieczna eksploatacje pokladu o róznej miaz¬ szosci jak i w warunkach znanych cisnien góro¬ tworu. PLOn the other hand, when the cutting machine is positioned in front of and in front of the section, the guards (3) are folded back so that the machine can pass in front of the section. The movement of the pressure plate (3) is controlled manually or automatically by the actuators (4 and 5). This casing completely protects the excavated side of the excavation against fallings and prevents the backfilling of the working compartment, and thus guarantees safe operation of the deck of various thicknesses and in conditions known to the pressure of the top of the formation.
