ABSTRACT:
An assembly for feeding objects from a conveyor on which they are conveyed lying down to a printing station of a printing machine where the objects are to be printed on. At the discharge end of the conveyor, at an ejection position, are provided a pair of spaced apart selector fingers having retaining and releasing positions for introducing and ejecting one object at a time. The object is accelerated or propelled from the ejection position by a tangential component of force exerted e.g. by a rotary brush or compressed-air jets, to a transfer carriage level and in alignment with the discharge end of the conveyor. Beyond the transfer carriage is a stabilizing back-up stop member having a suction head which steadies the ejected object on the transfer carriage. The transfer carriage is swung in a plane perpendicular to the axis of displacement of conveyor from its pick-up position to its feed-in position level with grippers which are adapted to introduce the object to be printed on into the printing station. Cams and linkages synchronize the movements of the selector fingers and a support lever swinging the transfer carriage between its pick-up and feed-in positions.
