Abstract
A flexible drive belt is comprised of a plurality of drive blocks which are assembled in a continuous loop by a plurality of tension bands extending between adjacent blocks. Each drive block has a pair of linear drive surfaces for transmitting drive forces along the straight span of the loop while being maintained in compression loading and a pair of rotary drive surfaces which frictionally engage conical surfaces of pulley members for converting the linear drive force to a rotary drive force by traversing the curved portion of the loop. Adjacent drive blocks are maintained in contact by the tension bands which operate through convex surface blocks disposed in concave surfaces formed on the drive blocks. These cooperating surfaces allow relative movement between respective drive blocks and convex surface blocks to permit the drive blocks to remain in abutment while traversing the curved portion of the continuous loop.
