ABSTRACT:
A bin-like arrangement with a mesh near its bottom collects dust from near the doctor blade of a Yankee cylinder in a paper making machine; a trough-like arrangement having a sloping bottom at the lower end of the bin receives the dust, and a plurality of horizontal air jets are provided at different heights at different points along the trough to entrain and remove the accumulated dust, preferably through a suction outlet. The system greatly reduces the dust released to the adjacent environment, without interfering with normal doctor blade operation, and without interfering with normal handling of the separated paper.
