Description

450 484 z den maximala storleken hos de stora kornen 8.1 uppgår till 80 pm och den maximala storleken av de små kornen uppgår till 60 pm. 450 484 z the maximum size of the large grains 8.1 is 80 μm and the maximum size of the small grains is 60 μm.

De 20 till 30 % återstående kornen 8.3 uppvisar varierande storlek. Kornen 8.1, 8.2, 8.3 är därvid inbäddade i grundmassan 7 som har en skíkttjocklek om 40 pm.The remaining 20 to 30% grains 8.3 have varying sizes. The grains 8.1, 8.2, 8.3 are then embedded in the matrix 7 which has a layer thickness of 40 μm.

Därigenom blir 70 till 80 % av kornen bärpunkter vilket med nödvändighet medför en motsvarande fördelning över gripytan, vil- ket i sin tur leder till minskning och till likformig fördelning av arkens belastning.As a result, 70 to 80% of the grains become bearing points, which necessarily entails a corresponding distribution over the gripping surface, which in turn leads to a reduction and to a uniform distribution of the load on the sheets.

Hos arkgripanordningen enligt uppfinningen är anslagen före- trädcsvis framställda av elastiskt material, varigenom dessa an- slag lättare kan ersättas. mIn the sheet gripping device according to the invention, the abutments are preferably made of elastic material, whereby these abutments can be more easily replaced. m
