Abstract:
A flexible armoured cord, as used in pay telephone units, is given an epoxy-resin coating, preferably by a fluid bed process. A very thin uniform coating is applied and averts wear and damage to the telephone unit housing without reducing flexibility of the cord. The coating is extremely abrasion resistant.
