Plate Dampers in the Tensioning Plate Dampers in the Tensioning
Lesnoy Zhurnal (Forestry Journal), 2021 The article analyses strengths and weaknesses of bandsaw machines. While analysing we have found the relationship between the weaknesses and the tension of a band saw. Its use as a cutting tool leads to a decrease in the lateral rigidity and stability of the cutting section on the pulling chain.
