A wire tensioning mechanism for tensioning a wire having an end one and an end two in a machine in which the wire has a means for attachment on end two and is fixed to the machine at end one, comprises a slide block, and a spring. The slide block is slidably mounted to the machine at end two of the wire, such that the slide block slides parallel to the wire. The slide block has a slot which is wider than the wire but narrower than the means for attachment, such that when the slide block is mounted on the machine, the wire end two can be slid into the slot such that pulling the slide block in the direction away from the wire forces the means for attachment against the slot, but does not allow the means for attachment to pass through. The slot is lined up with the wire such that when the wire is in tension, there are no side loads on the means for attachment.

Corona wire tensioning mechanism

A support and tensioning device for an elongated corona generating electrode includes a corona charger shield member that includes a first set of wall members for serving as a shield for a corona generating electrode. The shield member includes a second set of wall members shaped to define a recess formed at one end of the shield member for receiving therein a plunger member and a spring. The recess includes an inner positioned land for engaging a head end of the spring. The second set of wall members define the recess and include walls located to define a key slot opening which extends in a longitudinal direction of the shield member. A spring resides in the recess and engages the land to restrict movement of the spring within the recess. A hollow plunger member has a generally cylindrical sidewall for supporting the plunger for rotational movement in the recess and a land on or near a head end portion of the plunger member engages a tail end of the spring. The plunger member includes a wall having a slug receiving opening for receiving a slug formed on one end of the corona electrode and a slot extends from the slug receiving opening in the wall towards the head end portion of the plunger member. A key extends radially from the generally cylindrical sidewall and is located within the key slot opening for sliding movement therein to permit tensioning of the corona electrode. The recess receives the plunger member to permit rotation of the plunger member about the axis of rotation of the generally cylindrical wall to locate the key in the key slot opening to lock the plunger member into the corona charger shield member.

Charger wire tensioning mounting mechanism and method of using

A grid electrode for attachment to a corona charger includes a series of substantially parallel grid wires extending in a longitudinal direction of the wires. A flat metallic plate member is formed integral with the wires at one of the longitudinal ends of the wires. A cap member is connected to the plate member. The cap member includes a cover segment having a surface that overlies and is in planar contact engagement with a substantial portion of a respective plate member with a thickness of at least 0.5 millimeters and the cover segment being formed of a material that is substantially electrically more resistive than the flat metallic plate member.
