ABSTRACT:
An apparatus for inserting a coil of wire into a pipe which includes a rotatable drum for taking up a coil of spring wire, a guide for guiding the coil drawn from the rotatable drum, a push-pull device for applying external forces to the coil for feeding the coil into the pipe and retracting the coil out of the pipe, and a motor for rotating the guide and/or the drum. The drum and the guide are formed separately and are rotatable independently of each other, which rotation results in rotation of the coil of spring wire. The coil of wire has a rectangular or trapezoidal cross-section which enables the wire to effectively run through bends in the pipe without deforming or breaking.
