Indexing mechanism using pairs of radially disposed rollers engaged between adjacent cam ribs
 A roller gear cam index mechanism including a turret having pairs of adjacent rollers radially arranged on a circumference thereof. Each pair of rollers is engaged between adjacent ribs on a globoidal cam. The angle between the line up direction of every pair of rollers and the tangent direction of the turret circumference is a variable between 0 to 90 degrees. The rollers are modified globoidal rollers which are selected having difference maximum radii and vertex positions.
