<p>A transferring device for objects in which a reduced pressure must be applied continuously, which is adapted, when said objects in which a reduced pressure must be maintained continuously are transferred intermittently by means of a conveyor, to maintain the reduced pressure in said objects by opening the ones on one side of each said object of the normally closed valves provided on the both sides of each said object only when each said object stops moving so that the reduced pressure acts in each said object, and by closing said valves on said one side of each said object when each said object moves and at the same time opening the valves on the other side of each said object.</p> |
