Theradius to the outside of the curve may be made to suitthe specific requirements of the layout, from 2 feet 6inches to 4 feet 6 inches being usual. Curves fitted with straight rollers are satisfactory formany purposes, particularly where comparatively heavymaterial is handled. Straight roller curves should usual-ly be fitted with guards on the outside to insure the pack-ages from running off. Tapered rollers (Fig. 102) give the best resultj oncurves. The amount of taper depends, of course, uponthe radius of the curve, being greater for a short radiusthan for a long Fig. 103 Double or differential roller curves (Fig. 103), in whichthe outer rollers move faster than the inner, are muchused. They operate in a somewhat more satisfactory man-
