DEFINITION
Classification: 271/95
(under subclass 94) Device wherein motion is imparted to said element, which motion is supplemental to the turning of the element.
(1) Note. Included in this subclass is a device wherein a continuously turning suction member has additional movement to and from the stack, and a device wherein a one or more suction cups rotate or oscillate on their own axis and simultaneously revolve within a carrier about a second axis. The latter arrangement permits the suction cup to be retarded in its motion so that it is momentarily stationary with respect to the sheet which it will engage, even though the carrier in which it is mounted continues to rotate.
