Abstract
A wire feed amount detection mechanism is configured by magnets mounted at an outer peripheral surface of a V-grooved drive gear of a wire feed mechanism and a magnetic sensor mounted on a body. A reinforcing bar winding turn number-setting switch is provided on the body. A control portion controls a wire feed amount of a wire feed mechanism based on a set value of the reinforcing bar winding turn number-setting switch. The number of turns of the wire around reinforcing bars can be arbitrarily set, for example, to any one of 1 to 4, and the binding can be effected with a binding force corresponding to a strength required by binding portions. As a result, with respect to those binding portions requiring a low binding force, the binding is effected with a smaller turn number, so that the amount of consumption of the wire can be saved, and besides those pipes (such as electric wiring pipes and hot water pipes) which are lower in strength than the reinforcing bars can also be bound together.
