WARPING SHAFT CONTROL DEVICE Russian patent published in 2013 - IPC B65H77/00 D02H13/18 

FIELD: process engineering.

SUBSTANCE: invention relates to textile industry and may be used at warping machines. Control device comprises warping shaft drive motor, pressure beam drive motor, warping shaft rpm transducer, divider unit, warping shaft rpm counter, winding warp preset thickness generation unit, relay unit and adder. Note here that outputs winding radius and warping shaft rpm transducer are connected to appropriate inputs of divider unit its output being connected to first inputs of adder and relay unit. Second input of the latter is connected via warping shaft rpm counter to warping shaft rpm transducer, its output being connected via winding warp preset thickness generation unit to second input of the adder connected to pressure beam drive motor.

EFFECT: higher accuracy of warp density and length maintenance.
