Abstract
A method for making endless metallic ribbon drive belts for tape cartridges. Metal is electroformed on a steel ring sandwiched between two non-conductive discs. After removal from the steel ring, the plated ring is thinly coated with an elastomeric coating resulting in a compound belt having a low coefficient of elasticity in the base belt and a high coefficient of friction in the coating.
Claims3
A method of making metallic endless ribbon belts for peripherally driven tape rolls comprising,
- removably disposing a conductive belt between two solid insulating disks in contacting, parallel plane relation, thereby forming a sandwich structure,
- contacting the inside diameter of said conductive belt with a current carrying wire member,
- dipping said sandwich structure into metallic plating material, said metallic plating material having a stiffness in ribbon form greater than polyester,
- electrically plating a layer of said metallic plating material onto said conductive belt by directing current through said current carrying wire member, through said conductive belt and through said metallic plating material,
- removing said sandwich structure from the plating material and removing said conductive belt from the insulating disks, and
- removing said layer of metallic plating material from said conductive belt.
