from Storage Area into Dip Tank Containing Drawing Lubricant.
3. Tube Shall Index-Feed Automatically One at a Time into Pointer
Feed Rack.
4. Individual Tube Shall be Fold-Pointed Hydraulically.
5. Pointed Tubes Shall Index-Feed to Drawing Station.
6. Pointed Tubes Are Loaded into Pre-Draw Station for Drawing One,
Two, or Three at a Time.
7. Tubes are Pushed Over Mandrel and into Die Loading Tubes. There are
Nine Potential Load Tubes. (Previous Owner Used Only Six). Selection
of Load Tube is Dependent on ID/OD. Tubes Receive Internal Lubrication
