摘要：
The method of assembling a dot matrix print pin driving spring in relation to a solenoid having an axial hole, the spring carrying a cylindrical armature and the hole being designed for receiving the cylindrical armature, the solenoid being carried by a housing, positioning a plastic sheet adjacent the hole, with an edge of the plastic sheet overlying the hole, inserting the armature into the hole thereby partially drawing the plastic sheet into the hole so that it engages more than 180.degree. of circumference of the armature to center the armature in the hole.
