Abstract

PURPOSE:To reduce the equipment cost for sensing the number of the yarn breakage, by projecting a given quantity of light in the cross-sectional direction of a duct or flute by a light projecting element, reflecting the light zigzag, and sensing the quantity of received light. CONSTITUTION:The inner surface of a connecting pipe of a pneumatic duct 2 or flute connected to the suction side of a pneumatic tank 1 is planished to give a good light reflectivity, and the light projected by a light projecting element 3 is reflected zigzag to form a film of light. If a yarn breakage occurs, a fleece always crosses the film of light and is deposited on the pneumatic tank 1, and the quantity of light received by the light receiving element 4 in the set time is changed by the passage of yarns.
