Description: |
Multiple pulleys are used instead of the usual upper wheel. The short local bending radii on the small wheels would surely lead to premature blade failure. The purpose of the multi-wheel replacement for the usual upper wheel is to reduced the required band length by allowing the lower and upper carriages to be closer together. (We would have expected the main purpose of this design would be to reduce the inertia of the upper "wheel" and thus reduce problems of blade buckling when the cut meets with unusually high resistance, but this apparent advantage is not mentioned in the specification.) |
