Inventory #: VX-17256


The 40" Sendzimir Z-Mill as installed in 1946 had a mill speed of 0/400/800 feet per minute. The winders were arranged for two ranges of speed and tension; 0-535 feet per minute at 30,000 Lbs. tension and 0-1070 feet per minute at 15,000 Lbs. tension. About 1950, the control for the winder motors was changed to produce 0-340 feet per minute at 47,000 Lbs. tension and 0-680 feet per minute at 23,500 Lbs.. The original installation had 24" diameter solid mandrels and accommodated 54" outside diameter coils.
