Two forms of the machine exist, the essential difference of which ia that, in the one. the cutters are placed upon the cylinder with a large angle of obliquity to the axis, generally about :i:> . and are therefore bent and twisted until their edges form an oblique section of the cylinder, while the box. or the orifice through which the substance is protruded for being cut. lies parallel U< the axis of the feedinir-rollers. In the other variety, the knives are placed parallel lo the axis of the cylinder, and therefore straight in the edge, while the cutting box is elongated into a nozzle, and is twisted to aii angle of 1.')^ with the axis of the feeding rollers. To ihifi form of the machine I shall at present chiefly confine myself ') The cylinder straw-cutter with straight knives, as constructed by James Slight and Co., Edinburgh, at prices from £7 10s. to £8 lOs., is represented by fig. 285, being a view in perspec- tive of the macnine, while fig. 286 is a section of tlic principal parts; and in the two figures the .«amc letters refer to the corresponding parts of each. The machine is made entirely of iron, chief- ly cast iron. The two side-frames a a, are connected toijether, at a width of from 12 to inches, by the stretcher-bolts b h. two of which are seen in the right hand side of the figure, and a third below on the left : a fourth is formed of the bedplate r, which is bolted to a projecting bracket, :ind carries the cheeks or frame d of
