Abstract
A system for detecting the breaking of the woof in a shuttleless weaving machine wherein the woof is drawn into the machine from a supply. The system includes a detector circuit for detecting the travel of the woof into the machine, and generating a signal when the woof breaks, indicative thereof; a timing switch operatively associated with the weaving cycle of the weaving machine for generating a timing signal at a predetermined time period during the travel of said woof with respect to the detector; a monostable multivibrator responsive to the leading edge of the timing signal, gate means responsive to the timing signal and the output from said monostable multivibrator for providing a time period defining signal; second gate means for allowing the woof breaking signal to pass therethrough as a function of being ANDED with the timing period defining signal; a flip-flop being set in response to the output from the second gate means; and a relay which is energized by the set output from the flip-flop, for disconnecting power from the weaving machine.
