Such belts can therefore be of indefinite length without piecing, and of a width limited only by the length of the calendering rolls. Rubber belts are suitable for damp places, but will not withstand high heat, nor can they be shifted by a jerk from fast to loose pulleys. They are much used in grain elevator practice. Raw-hide, canvas, and composite belts have also been used. A convenient formula for belt transmi ion is that each inch in width will transmit one horse-power, where the speed is 600 feet per minute. Where the arrangement of belts is unfavorable to transmi ion by this means, the belt must be made wider, or must be run faster. The last joints in endle belting are made by lacing or by special forms of hooks or studs. Where the driving and driven axis are separable, or where a tightener or straining pulley can be used, even the last joint may be cemented and the shock at high speeds and the weakening effect of the lacing may be avoided. Double leather belts are used for higher strains.
