Title: Detection of yarn breakage and equipment therefor
Inventor: SHINODA TATSUO
IPC: D01D11/00
Filed: 1989-06-30
Abstract: PURPOSE:To sensitively detect yarn breakage by arranging plural light emitting elements on one side of the lower part of a spinneret having many nozzle holes and plural receptors facing thereto across filament yarns and detecting change of the amount of light received due to rounding of the broken end of a yarn. CONSTITUTION:A group of light emitting elements 20 composed of plural light emitting elements (P) and capable of radiating light to a through area of all the filaments extruded through nozzles 17 are arranged on one side of the lower part of a spinneret 10 having many nozzle holes 17 and a group of receptors 21 composed of plural receptors (R) capable of receiving light radiated from the light emitting elements (P) of the group of light emitting elements 20 and partly intercepted by the filaments are arranged facing to the above mentioned group of light emitting elements 20 across the filaments. When yarn breakage occurs, the broken end of a filament is spontaneously formed into a ball-shaped body 18 on the outlet side of the nozzle to intercept more amount of light from the light emitting elements. The reduction of the amount of light received by the receptors (R) due to the above mentioned interception is detected, thus detecting yarn breakage.

Filed: 1989-07-04
Abstract: PURPOSE:To steadily operate a gas vent valve at a specified pressure over a wide temperature range by forming the vent valve in the form of projection so as not to be in contact with the periphery of a vent hole. CONSTITUTION:A vent hole 11 is installed in the flange of a sealing plate 8 formed in the shape of a cap, and a vent valve 12 is heat-bonded in the periphery of the vent hole 11. The vent valve 12 is formed in the form of projection so as not to be in contact with the periphery of the vent hole 11.
