Abstract: The present invention relates to an oiling frame for chemical fibre machines in which signal emitted by a sensor disposed above the filament bobbin winding machine of the chemical fibre machine for detecting broken filaments in any fibre strand is received by a cylinder for the same to actuate a set of blades below oil nozzles in the oiling frame so that the blades may instantaneously and simultaneously cut the fibre strands moving downward from the oil nozzles. Since the blades and the blade covers are designed to have several sharp edges which facilitate quicker and more precise cutting thereof while the blades can be economically made of non-expensive metal material.
