Belt drive for providing uniform rotary movement e.g. for electronic engraving machine for printing cylinder manufacture, uses parallel belts circumferentially offset from one another

摘要

The belt drive uses a number of parallel drive belts rotated in the same direction (10), which are fitted so that the same points around their circumference are offset from one another, e.g. 2 parallel drive belts with the 0 degree reference mark (8) of one belt aligned with the 180 degree reference mark (9) of the other belt.
