FIELD: machine building.
SUBSTANCE: proposed device comprises material unwinding means, material transfer means as well as material transfer readout and processing means. Material transfer means are composed of the system of two transfer rollers, each being equipped with motor and measurement result correction system with due allowance for material deformation. Said system includes resilient pneumatic drum with its shaft engaged with encoder and pneumatic channels to communicate with digital pressure gage. It incorporates also read data conversion electronic units connected via interface units with the processor.
EFFECT: higher precision of measurements, simplified design.
