Abstract
479,682. Breaking or crushing sisal leaves-&c. McCRAE. J., and FAIRBAIRN LAWSON COMBE BARBOUR, Ltd. July (i, 1937, No. 18661/36. [Class 120 (i)] Crushing-apparatus for treating the leaves of sisal and like plants in preparation for full decortication comprises pairs of circumferentially ridged rollers 3, 4, Fig. 1, of longitudinally fluted rollers 2, 5 and of plain rollers 6. The ridges 3a, Fig. 3, of the upper and lower rollers in the pairs 3, 4 are in the same vertical plane and comprise in section a rounded top a, Fig. 6, which is of less radius than the sides a<1> and grooves a<2> so that the leaves are not cut but are crushed and spread. The ridges on the rollers 4 are more closely spaced than on the rollers 3. The longitudinally fluted rollers are formed with sharp edges x, Fig. 5, and division plates 9 are provided between adjacent leaves. The rollers are spring-pressed together and their distance apart is adjustable. A feed table 8 having a reciprocating plate 8a is provided. Specification 479,683 is referred to.
