<p>Objects such as cartons (16) supported in transport holders (110), are carried on a first conveyor wheel (140) and transferred to a second conveyor wheel in respective transfer operations. Each conveyor wheel has circumferential spaced recesses for carrying such objects, each recess containing a moveable magnet (156) for holding a said object. The wheels run tangentially to one another so that each object on the first conveyor wheel during each transfer operation is momentarily simultaneously in recesses of the first conveyor wheel and of the second conveyor wheel. Transfer is triggered by the timed withdrawal of the magnet holding the object in the recess of the first conveyor wheel by a cam (170) leaving the object held by the magnet of the second conveyor wheel. Cartons may be bottom sealed, filled and top sealed on respective conveyor wheels.</p> |
