摘要
A rebar tie wire reel (110) for a reinforcing bar binding machine has a first flange (118), a second flange (120) spaced from the first flange, a hub connecting the first and second flanges and a wire (124) wound around the hub. The first flange (118) has an outwardly facing major face (134) and an outer periphery. The outer periphery is defined by a plurality of edges (170, 172, 174, 176). The plurality edges include a first edge (170) and a second edge (172) that are configured such that, in use, an amount of rotation of the rebar tie wire reel can be determined using signals provided by a movable element of a contact sensor when during rotation of the wire reel, the first edge, major face and the second edge successively travel past the movable element.
