ABSTRACT:
A final gear (23) and a ball screw shaft (24) of a rotation drive system of a binding line twist mechanism are connected by a spline and a shaft portion of a center clamp plate (26) of a binding line clamp apparatus (25) is connected to a front end of the ball screw shaft (24). A shift mechanism for moving the ball screw shaft (24) and the binding line clamp apparatus (25) in a front and rear direction by a slide motor (22) is provided. A wire (W) is wound around a reinforcing bar (S) by a binding line feed mechanism, the wire is grasped by a front end portion of the binding line clamp apparatus (25) and thereafter, a shift mechanism applies a tension to a loop of the wire by moving rearward the binding line clamp apparatus (25). The binding line clamp apparatus (25) is rotated by a twist motor (21) and the shift mechanism twists up the wire by moving forward the binding line clamp apparatus (25). Since the wire is applied with the tension and twisted, a reinforcing bar binding strength of the wire loop is stabilized.
