MACHINE FOR FASTENING REINFORCEMENT, DRUM FOR SUCH MACHINE AND DRUM ROTATION CONTROL METHOD Russian patent published in 2007 - IPC B21F15/00 E04G21/12 G01P13/00 

Abstract RU 2304482 C2

FIELD: equipment designed for fastening reinforcement by means of wire, for example for fastening mutually crossing reinforcing rods, possibly in building.

SUBSTANCE: machine includes housing; rotating drum carrying wire for fastening reinforcing rods; unit for controlling drum rotation; one or more detected objects. Detected object may be placed on lateral surface of drum. At controlling rotation of drum, said object is detected through opening of lid providing light reflection from light irradiator. Light reflected from detected object and light reflected from lid is received for determining difference between their intensity values.

EFFECT: enhanced operational reliability of machine, elimination of errors at monitoring wire consumption.
