Abstract:
1. A process for manufacturing a wire wound flexible shaft, comprising the steps of: winding at least one layer of wire upon a core wire to form a partially completed flexible shaft; preheating said partially completed flexible shaft; spraying the preheated partially completed flexible shaft with a liquid carrier containing a lubricant, so that the carrier is vaporized upon contact with the shaft and the lubricant Is deposited on the exposed surface of the shaft; subsequently winding another wire layer on the partially completed shaft having the lubricant deposited thereon; repeating said heating, spraying and subsequent winding steps one or more times; and heating said wires having lubricant deposited thereon at a temperature sufficient to cause the deposited lubricant to bond to the wires.
