FIELD: process engineering.
SUBSTANCE: invention relates to electrically driven tools used for joining reinforcement rods. Proposed tool comprises drive motor 2 to feed wire 100, coupling 5 furnished with hook 6 to grip and twist wire 100, and motor 4 to drive coupling 5. Besides it includes pickup H to detect the position of rotor 15 of motor 4. Note here that one or two magnitudes of rpm or position in revolution of motor 4 are measured by detection pickup signal while coupling position is defined from measurement results.
EFFECT: higher reliability.
