Abstract: A process and system for repairing electromechanical cables having an external armor wire layer using a butt welding technique and an arc vanishing machine. A short (break) in a cable having both an external and inner helically wrapped wire layer over an inner conductor(s) is located using conventional techniques. After the inner conductor(s) and inner wrapped layer are repaired (i.e., spliced), the outer wire layers are reconnected using a butt-end welding process and form individual arc shapes. The cable automatically passes through dies on headers to vanish (displace) each of the arcs to the end of the cable. A safety system activates an alarm to shut down the system when a jam occurs before any cable wires break. The system is reactivated after the jam is cleared.

Abstract: A cover plate for covering exposed conductive wires of a flat cable is attached to a surface of an attaching plate for holding the flat cable, and insert molding is performed in such a manner that the cover plate is included. Therefore, direct contact of a portion of flows of synthetic resin for use in performing insert molding that flows along a surface of the attaching plate for holding the flat cable with conductive wires of the flat cable can be prevented. Moreover, if the synthetic resin introduced into another surface of the attaching plate for holding the electric wires flows in joint portions between the conductive wires, the conduction wires of the flat cable are pushed against the cover plate due to the flow of the synthetic resin so that the conductive wires of the flat cable are supported. Thus, the conductive wires of the flat cable can be protected from excess stress when the insert molding operation is performed. Thus, breakage of the conductive wires of the flat cable can be prevented.
