A device for automatically regulating the thread consumption of warp knitting machines in which plural warp beams are propelled from a mainshaft by respective variable drives is provided. This device consists of electrical contact means for determining the r.p.m. of the mainshaft, together with a setting device means for fixing the desired speed of thread consumption. A control mechanism is also provided for part of the device which includes electrical impulse generator means on the respective warp beams for indicating thread consumption together with a counter means including subtracting mechanism means for measuring the difference between desired and actual values of thread consumption and having output signal means for adjusting the r.p.m. of individual warp beams through said variable drive. The device further includes switching means for adapting the control mechanism means for successively regulating the r.p.m. of plural warp beams of one or more warp knitting machines through connection with the electrical impulse generator means and the variable drives of the respective warp beams, and means for causing switching of said control mechanism means from one warp beam to another in response to signal from the electrical impulse generator on the warp beam last regulated at the time of switching.
