Abstract

PURPOSE: To positively detect thread during weaving, by positioning a luminous instrument and a light receiver at the lower side of thread to be detected, and by arranging a small reflector at the upper side of the thread.
CONSTITUTION: A luminous instrument 2 and a light receiver 3 are mounted at the lower side of thread 1 to be detected, and a small reflector 7 is installed to an intersection point 6 of both directional shafts 4, 5. Thus, projecting light strikes upon the thread 1, remaining light is reflected on the surface 6 of the reflector 7 and again strikes against the tread 1 and the residual light passes through a light receiving window 11 and enters the light receiver 3. Consequently, the thread 1 can positively be detected because the thread 1 twice intercepts light and the difference of the quantity of light of the light receiver 3 is enlarged.
