Abstract

A brake mechanism of a wire reel arranged in a reinforcing bar binding machine in which a binding wire 3 is fed from a wire reel 2, wound round reinforcing bars 7, and twisted by a twisting hook 8 so that the reinforcing bars can be bound with the binding wire, comprises the steps of: a brake means 11; and a brake lever 12 for operating the brake means 11, wherein the brake lever 12 is linked with a motor 9 for driving the twisting hook 8, the brake means 11 is operated by the brake lever 12 when the twisting motor 9 is normally rotated so that the brake means 11 is engaged with the circumferential edge portion of the wire reel 2 so as to apply the brake to the wire reel 2, and the brake lever 12 and the brake means 11 are reversely operated when the twisting motor 9 is reversed so that the braking operation can be released.
