Zastapienie tego sposobu przez skrawanie struzki wedlug patentu nr 40598 ogromnie ulatwia prace wrebienia.Dla zmniejszenia energii potrzebnej do wyko¬ nywania wrebu w minerale, dla zwiekszenia wy¬ dajnosci i posuwu wrebiarek i kombajnów oraz dla zmniejszenia zuzycia nozy wrebiarkowych wedlug wynalazku zastepuje sie dotad uzywany nóz w postaci pazura wedlug normy PN/G-56015 nozem- o ksztalcie zblizonym do typu nozy ma¬ szynowych, uzywanych do skrawania i toczenia podobnej do nozy wedlug normy przedstawio¬ nej na rysunku w widoku perspektywicznym.Glówna krawedz tnaca l noza jest wydluzona i posiada dlugosc kilku centymetrów a przej¬ sciowa krawedz tnaca l* posiada dlugosc okolo centymetra. Katy pochylenia plaszczyzn ostrza noza winny byc przystosowane do twardosci wrebionego mineralu. Ostrze zaleznie od po¬ trzeby powinno byc zaopatrzone w plytki skra¬ wajace z twardego stopu.

The replacement of this method by the cutting of the plow, according to patent No. 40598, greatly facilitates the work of the notching. in the form of a claw according to the PN / G-56015 standard with a knife - with a shape similar to the type of machine knives, used for cutting and turning similar to knives according to the standard presented in the drawing in a perspective view. The main cutting edge of the knife is elongated and has a few centimeters long and the transitional cutting edge l * is about a centimeter long. The inclination angles of the knife blade surfaces should be adapted to the hardness of the mineral. The blade should be provided with hard-alloy steer plates as required. PL
