ABSTRACT:
A wire feed station of a wire processing system draws a supply of wire into the system. The wire feed station includes first and second feed wheels that create a nip to pull the wire through the feed station. A drive assembly is coupled to the first and second feed wheels to cause rotation of the feed wheels. The drive assembly includes first and second drive shafts that are coupled to the first and second feed wheels through a pair of flexible couplings. The flexible couplings allow the first and second feed wheels to move relative to each other to adjust the feed nip. The flexible couplings allow a single drive motor to rotate the first and second feed wheels through a pair of drive shafts without the use of a complex belt or gear assembly.
