A warp thread monitoring apparatus for looms wherein each properly tensioned warp thread passes through an associated thread monitoring lamella or blade and retains such in an elevated position, and upon rupture of the relevant warp thread this lamella then drops into a lower position, thereby activating a release or triggering mechanism for sounding an alarm or stopping the loom. According to important aspects of the invention, a channel system is arranged beneath each row of thread monitoring lamellae and upon rupture of the relevant warp thread the corresponding lamella drops into this channel system to interrupt the flow of an air current forced from the inlet side of the channel system to the outlet side thereof. This in turn affects the operation of a pneumatic flow sensing device influencing the trigger mechanism for sounding the alarm or stopping the loom.
