DEVICE FOR ADJUSTMENT OF INTEREST CONTENT OF BINDING MATERIAL IN CONVEYANCE FROM REINFORCING FIBERS BUNDLES Russian patent published in 2018 - IPC B05C3/10 

FIELD: control systems.

SUBSTANCE: invention relates to devices for controlling the process of impregnation by a binder of a moving tape from bundles of reinforcing fibers and can be used in the manufacture of articles of composite materials by the wet winding method. Apparatus for adjusting the percentage of a binder in a moving belt from bundles of reinforcing fibers comprises an impregnating device with a basket, partially immersed in a binder, an impregnation bath with a heating element, a device for continuous ultrasonic monitoring of the percentage of binder in the conveyance from bundles. Results of measuring the device for continuous monitoring are transferred to the control unit of the electromechanical drive of the knife installed in front of the impregnation zone, regulating the application of the binder to the basket of the impregnating device. Adjustment of the binding of the binder to the impregnating basket is carried out by the knife due to a change in the clearance "knife-basket" controlled by two independent actuators with intelligent drives through the knife position sensors located on its edges. Specification of the thickness of the binder layer gives the binder content regulator based on the binder content setting device and the binder content monitor in the moving belt from the bundles.

EFFECT: increasing the accuracy of adjusting the percentage of binder in the moving belt from bundles of reinforcing fibers.
