Barrage balloon manufacture. Seamers at work. Putting rubber cement on both surfaces which are to be fastened together, these workers assemble individual pattern pieces into strips or "gores" for barrage balloons being made for army balloon corps. By an ingenious arrangement of folds, strips nearly a hundred feet long can be handled by each worker on the table in front of him. General Tire and Rubber Company, Akron, Ohio

Three-inch A.A. cartridge cases. Between the drawing operations which process an antiaircraft cartridge case from a flat metal disc, the partly-finished cases are washed and annealed. When they move on to the next drawing operation, the surfaces are free of scale and other adhesions and the metal is soft, uniform and ductile

This Norton cutter-grinder which had been specially adapted to grind cams on the motor shaft for the electric dry shaver which this New England plant normally produces, has now been converted to grind permanent magnet rotors for machine tool motors. The conversion was accomplished with new jigs and fixtures and slight changes in the head. This is a tricky job well suited to the skill of this plant's workers. The metal is alnico and the octagonal shape consists of surfaces which are arcs drawn from the center of the piece. Schick Inc., Stamford, Connecticut

Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells go through the first drawing operation. A brass cup formed from flat disc is fed to a huge press which draws it into a tubular shape with one rounded closed end. Washing and annealing precedes the first draw and will follow it. Washing cleanses surfaces for future operations. Annealing removes strains set in the metal by the forming and drawing operations

Three-inch A.A. cartridge cases. Cartridge cases for three-inch antiaircraft shells are produced by a series of operations that transform a flat brass disc into a case ready for loading with propelling charge and shell. Between each operation there is careful washing to remove all scale and adhesion and to leave surfaces clean for later processing. The big Midwest plant doing the work is well equipped to handle it in stride

Production. Milling machines and machine castings. Precision gears are essential for machine tools to ensure accurate, smooth, quiet operations and long life. This gear grinder -- itself a machine tool -- is perfecting the working surfaces between the teeth of a milling machine gear. The milky liquid is coolant used to control the temperature at the grinding point so that the delicate physical character of the metal, produced by predetermined and careful heat treating, will not be disturbed. Location: a large Midwest machine tool plant
