ABSTRACT:
A helical band is produced by applying a layer of heat-settable material on to a rotating support to one side of the axis of rotation. Heat is applied to the layer, as by the support while it rotates, for a length of time sufficient for the material in the layer to set to a required extent to form the band. The band is removed before it comes into contact with the material being applied on the support. The band is preferably made of electrically-insulating material so that it can be wound helically round and bonded to a cylindrical rod of electrically-insulating material to form a helically flanged insulator for use in an overhead electric power transmission line, the flange-forming band defining along the rod a helical leakage path of substantially uniform width.
