FIELD: engines and pumps.
SUBSTANCE: reinforcing bar wire-tying machine incorporates wire drum with data detection and wire identification device designed to detect and identify wire on the drum flange side surface and allows wire twist force or feed amount control proceeding from the wire identification data detected in starting wire-tying with the help of the rotation detection lever. The drum comprises cylindrical bush with a pair of flanges on its sides and has an extending section on the outer side surface with a reflecting symbol on the bush outer side surface. The type of wire coiled around the said drum is determined from the number of disclosed reflecting symbols when the detection signal is input from the aforesaid lever. The wire data is detected at the drum high-rotation wire-tying speed, not in coiling the wire on the drum.
EFFECT: reliable wire-type data detection.
