Cutting machine

Henequen. Agavefourcroydes grows ia Mexico where it was first cultivated by the Mayans ia the Yucatan (Yucatan Sisal). The plant produces for 20—30 years. The lower bottom leaves, which are up to 2 m long and 10—15 cm wide, are cut, machine decorticated, and cleaned. Henequen fibers are white to yellowish red and are inferior to sisal ia strength, cleanliness, texture, and length, the other grading criteria. Henequen is grown for local use ia Cuba (Cuban Sisal) and El Salvador. Twiae, small ropes, coarse mgs, and sacks are made commercially from henequen. 

In commercial practice, packaging is produced from continuous web on intermittent-motion thermoforming/die-cut machines. The web edge is clamped and conveyed into a heating box. If a plastic with a narrow softening temperature is used, heating is carefully controUed from top and bottom. 

Machining costs (labor and overhead) in the United States have an estimated value of > 300 x 10 /yr. The cost of labor and overhead for machining is based on the estimated number of total metal-cutting machine tools in various metal-cutting industries (1). This value does not take into account the cost of raw stock (work material), cutting tools, and many other support faciUties. An estimated breakdown of cutting tool costs is given in Table 13 (172). Because of the competitive nature of these industries, most prefer to keep cost information proprietary. 

The next significant event in the evolution of the SRM compressor was the application of a Holroyd rotor cutting machine to the production of the rotors. Prior to this event, producing the rotors was both slow and costly. In 1952, the first special Holroyd machine was delivered to How-den Company, a licensee in the U.K., who later contributed to the development of the oil-flooded compressor.

Rubber coated fabric is cut to give a bias to the fabric on its application to the tyre carcass. The knife angle can be adjusted in the cutting machine.

Purification.—Tfte Cutting Machine.—When a visitor enters the works of the Gutta-Percha Gompany, he observes in the yard or court the imported blocks of the raw material piled in great heaps. These blocks, when they are required for use, are first taken from the heaps to the cutting or slicing machine, which is a large solid vertical disc of iron, armed on one Fig. SOI. 

With tlio exception of the inspissated juices, this condition is gained by grinding or cutting machines which reduce tbs roots, branches, or barks, to a fino powder. 

The central drum makes twenty-five revolutions per minute, and in the course of twenty-four hours grinds about eight thousand six hundred pounds of bark. The cutting machine already described is capable of supplying three grinding mills.
