ABSTRACT:
A process suitable for making a corona wire assembly for use in an electrostatographic reproduction apparatus involves attachment of a terminal to a corona wire. The process has the steps of positioning said terminal and said corona wire such that a portion of the corona wire is touching the terminal at a contact position; one end of the corona wire is held by a holding device and the unattached end is drawn under a tensioning force from 1 to 3 N across a wire clamp; applying laser energy to the contact position for melting at least part of the terminal in the locality of the contact position; and solidification of the molten part of the terminal for forming a bond with the corona wire. In a preferred aspect, the process includes the additional step laser trimming off of an end-tip of the corona wire.
