Abstract
A device for holding flat objects comprises a motor on the output shaft of which is mounted a rotatable terminator assembly. A turbine is rotatable by the motor within the terminator assembly, which is partly partitioned forwardly of the turbine. The terminator assembly comprises a flat suction chamber open laterally and containing the turbine and a flat holding chamber forward of and communicating with the suction chamber. This has an open holding surface facing forwardly which is closed off by an object to be held. A separate motor-gearbox unit coupled to the terminator assembly controls its orientation relative to the turbine drive motor.
