This abstract first appeared for US patent application 20240416445 titled 'DUAL WIRE DRIVE SYSTEM
Original Abstract Submitted
a welding or additive manufacturing wire drive system includes a shaft. an inner spindle is mounted on the shaft. the inner spindle has a first hub for receiving a first welding wire spool mounted on the inner spindle, and a first flange around the first hub. an outer spindle is mounted coaxially on the shaft with the inner spindle and includes a second hub for receiving a second welding wire spool mounted on the outer spindle, and a second flange around the second hub. a first friction brake is in contact with the inner spindle. a second friction brake is in contact with the outer spindle. a biasing member is located between the inner spindle and the outer spindle and applies a bias force from the outer spindle to the inner spindle to push the inner spindle against the first friction brake. the inner spindle and the outer spindle are configured for independent rotation at different angular velocities from each other.
