Vacuum metallizing of polymer films, such as cellulose acetate, butyrate, and Mylar, is performed in essentially the same way. Film rolls are unreeled and rewound during the deposition process to metallize the desired surface. A protective abrasion-resistant coating is then applied to the metallized surface in an automatic coating machine. 

Thread rolling is possible with automatic screw machines of sufficient power and rigidity. 

In roll-fed automatic thermoforming machines, the clamping edges are always format parts, which mean that depending on the size of the form segment, the... 

Lubrication plays a vital role in the operation of industrial plant. For example, in a heavy rolling mill the lubrication system, though mostly out of sight in the oil cellar, may have a capacity of many thousands of gallons and exceed in bulk the mill itself. Lubrication systems of this size and complexity are usually fully automatic, with many interlocks and other safety features. Even with the smallest machines, automatic lubrication is becoming more popular. Where an automatic system would be impracticable or... 

A recent cartridging machine is the Rollex, designed by the firm of Niepmann Sons. This operates on an entirely different principle in that the explosive is first rolled into a sheet and then portions of this sheet are cut off and automatically wrapped in paper. It can also be used for cartridging semi-gelatine explosives. 

Some other breads are shaped by machine or hand. Machines exist to shape baguettes or rolls automatically. 

The simplest type of automatic control of machines with a floating roller is gap control. The gap is measured with linear transducers installed either between the two roll shafts (Figure 292) or between a fixed point on the frame and the movable roller. If gap control is used, the optimum operating pressure... 

The automation of firework production is something that has come only slowly. Paper caps are produced on automated machinery at a rate of 25 million a day, and machines are used to roll and label tubes, fill certain compositions, etc. The writer has not yet seen any machine that completely automates the production of any given firework and suspects that even if time and money were put into such a machine it could only be used for mixtures that were limited in sensitivity or simple in form. Filling machines and automatic presses are used in Europe, but friction occasionally causes explosions or fires. The machines are so arranged that they can be quickly cleaned and restarted. 

This equipment is used to feed the glue mix automatically to various woodworking machines such as roll coaters, jointing machines, plywood machines, furniture assembling machines and laminating machines. 

Figure 6-17. Coaxial electrical cable s PS insulation buttons are here being injection molded, using a cold runner system, but it could also use a hot runner one. In this continuous production process, the injection-molding machine (IMM) is on a platform that moves in a rectangular pattern to permit the platens to open and move away from the buttons, as well as to move at the speed of the six-cable copper wire line when the mold is closed and the IMM is injecting the PS. Copper wires are started out with large diameters and are pulled through reduction squeeze rolls to their final thin diameter prior to entering the IMM. The wire-reduction line is to the left of the IMM, with the wire pullers to its left. Automatic devices remove the runners on-line just after they leave the IMM and the additional cooling station fiiat is shown in this view.

Most of the major materials for flexible circuits, such as copper laminates and coverlay films, are supplied in rolled form. The first process of manufacturing is to sUt and cut the rolled materials into workable sizes. It is possible to cut with a manual sharing tool however, an automatic machine is recommended to get an exact size without handling damage. 

Sheet should be cut to the desired length and stacked flat. Usually, a traveling power shear cuts the sheet automatically to the desired lengths. Roll temperatures have a decisive influence on the quality of the finished sheet. If the rolls are too hot, the sheet will not be cooled sufficiently for easy handling and will tend to curl in the transverse direction. If the rolls are too cold, the sheet will curl in the machine direction, resulting in a pitted surface. ...
