The SARCS (Sheldahl Automatic Roll Changing System), SARRCS (Sheldahl Automatic Rewind Roll Change System), and SAURCS (Sheldahl Automatic Unwind Roll Change System) subseries contain files relating to the automatic roll rewinding/unwinding machine. These machines were designed to rewind and unwind rolls of any of the standard Sheldahl laminates or films. The LEM 909 files contain correspondence with Richard Lemke (LEM) and Shelly, as well as other documents, relating to problems with a model 909 SARCS machine. The JED 1128 file has similar information, i.e., James E. Donaghy (JED), model 1128, as do the LEM 1019 files. The SARCS Project files contain general information and design sketches of all of the different types (SARRCS, SAURCS, and Patent 95, which combined the rewind and unwind components) and models of SARCS machines from August of 1990 through June of 1995. The final file in this subseries has the billing and correspondence information from attorneys Haugen and Nikolai.
