This invention relates to an, apparatus for ro

in which a large number of unit articles must be

the same apparatus;

cessed or fitted‘ with protuberances. Likewise,
grooves, channels and irregular shaped recesses
may be present in certain articles while others
may be of a rectangular,‘ oval, elliptical, or other
shape. The present apparatus provides means
for positioning such articles quickly and accu
rately without delays which might be occasioned
if it were necessary to place the object in a holder
More particularly, the invention relates to a de

necessary to. subjectsuch articles to rapid rota
