ABSTRACT:
The weft thread monitoring apparatus contains a detecting circuit incorporating the functions of a thread recognition circuit and a control circuit for controlling the intensity of a thread sensing or scanning beam which is affected by extraneous effects like outside light, the presence of fluff and other influences. A monitoring and controlling circuit defines monitoring and control intervals to differentiate between thread signals which are respectively correctly and incorrectly related to the operating cycle of the weaving machine and to possibly cut off the weaving machine. A sensing head can be simply mounted and dismantled at any desired location at the reed of the weaving machine so that different widths of the woven material or fabric can be manufactured using the same reed and the weft thread can be monitored. By periodic indication of the thread signal the correct run or operation of the weaving machine also can be monitored. The thread signal indication is conceived such that malfunctions can be recognized from such indication.
