APPARATUS AND METHOD FOR TENSIONING RESISTIVE WIRE Abstract An apparatus and method for use in the attachment of a length of resistive wire under a preselected tension to wire- supporting end portions of a pair of generally parallel, resil- ient posts attached to a post support member. The apparatus includes a spindle for rotatably supporting a spool containing a substantially continuous supply of the resistive wire from which the length of resistive wire to be attached to the resilient posts is obtained; a brake for applying a rotational drag on the spool at least as great as the preselected tension; a gravity- actuated tension arm for applying the tension to a portion of the continuous resistive wire extending from the spool, the arm engaging the extending portion of continuous resistive wire and being supported for pivotal motion in a substantially vertical plane, the arm having an adjustable counterbalance weight for adjusting the tension applied to the preselected tension; a retainer for releasably holding the post support member to position the pair of resilient posts in a desired location and planar orientation for attachment of the length of resistive wire, the retainer including a wire index for positioning of the length of resistive wire substantially transverse to the resil- ient posts, and further including a lockably adjustable holder for holding the support member and selective longitudinal posi- tioning of the wire-supporting end portions relative to the length of resistive wire; a pair of releasable wire clamps, one of said clamps being positioned to the outside of each of the posts for selectively clamping the extending portion of the continuous resistive wire; a wire guide for positioning of the length of resistive wire in substantially coplanar relation to the resilient posts; and a tension gauge for measuring the tension on the extending portion of the continuous resistive wire.
