A spinning or twisting machine has a plurality of spindles which are rotatable about upright axes aligned in a row and which are each provided with a whorl tangentially engaged by the outer face of a straight stretch of a flat drive belt. This machine is driven by a system comprising a motor having an output pulley rotatable about an upright axis adjacent the flat drive belt, a drive wheel operatively tangentially engaging one face of the flat drive belt at a drive location, and another belt reeved over the output pulley and drive wheel and driving the latter from the former. A pinch roller is operatively engageable with the other face of the flat belt at the drive location and is pressed thereagainst to pinch the flat belt between the pinch roller and the drive wheel.
