Improvements in or relating to ribbons of foils, films or the like containing cellulose derivatives and to wires and other articles covered therewith

Talc or like solid unctuous substance is applied to ribbons of foil made of or containing cellulose derivatives, and the ribbons are then wrapped on electric conductors such as wires, cables, ribbons, bus-bars, and coils. The solid lubricant does not impart tackiness as is the case with oils, and it enables narrow ribbons of foil to be passed at high speed through the guides of the winding devices, and to be unwound from packages without sticking. Instead of talc, there may be used a metallic salt of a fatty acid such as zinc stearate or palmitate, or aluminium oleate, or bismuth oxychloride, or fuller's earth. The solid lubricant may be applied by rubbing, dusting, or blowing on to the surface of the foil. The quantity deposited is preferably so small that the transparency is not materially affected and subsequent cementing or welding is not interfered with. The foil may be of cellulose nitrate, acetate, formate, propionate, or butyrate, or of methyl, ethyl, or benzyl cellulose. The foil ...
