Abstract

A support wire is placed through the hole of a device such as a ceiling clip for suspending an acoustical ceiling, and the wire is bent to provide a layover loop to which the device is slidingly attached, the tail of the layover loop being as long as a significant portion of the perimeter of the layover loop. The wide portion of such loop is placed in the vertical slot of a pivoted faceplate yieldingly urged to a vertical upright position, and the apex [crossover portion] of the loop is positioned in the conical zone in which the conical face have an angle, with respect to the axis of the wire-wrapping shaft of from 30 to 60 degrees. The stem is positioned in a slot substantially coaxially with the shaft, with the tail in the slot of said rotatable shaft. When the shaft is rotated, the conical faces guide the tail to wrap around the precursor to provide from about 2 to about 8 helical wrappings to stabilize the loop to which the clip is slidingly attached. Because of a one-way clutch, the shaft can be manually rotated in one direction to vertically and upwardly align the slot, thereby permitting removal of the product and the insertion of the next precursor. A foot switch is actuated by the operator to initiate and stop the wire-wrapping step. The gear coaxial with the shaft has a slot extending from the zone between the teeth of the gear to its center and sufficiently beyond to accommodate the coaxial stem of the wire.
