only simple revolution movement mainly against inertial forces is necessary that allows also to increase operation speed in the simplest embodiment shown in fig1 complete locking cycle demands one revolution of the body of revolution 2 in an improved embodiment number of locking cycles per one revolution may be doubled to increase operation speed such an example is schematically shown in fig2 where the input end of the apparatus is at the stage of carriers transportation the loading arrangements 10 two locks 12 another embodiment of the locks and a part of the working chamber 13 the improvement here is in the following the cavities of the locks 12 are provided with bulkheads 14 between two locking compartments 5 and the carriers transportation means not shown are able to operate synchronously but in opposite directions in this particular case openings 15 are arranged to provide the locks reloading in half a revolution of the body of revolution 2 however in case of adjacent arrangement of openings 15 the described improvement is more effective because it enables to provide synchronous locking of counterflows of the carriers with articles these possibilities are illustrated by a flow line deposition apparatus which is schematically shown in fig3 this apparatus includes a.
