WIRE TYING MACHINES

摘要

A machine for tying a wire around one or more objects (2) comprises a wire sensing arrangement (68, 76) for sensing the presence of the wire in a predetermined part of the machine, the wire sensing arrangement being configured to detect presence of the wire (46, 52) when the wire closes an electrical circuit so that an electrical current passes through part of the wire (46, 52). The electrical resistance of the wire may be measured to determine the wire type.
