Abstract: A device for the transferring and accumulating of packing elements in the form of a box which is open on one face, using an air conveyor on an accumulating path in a closed loop (1) to which there is connected at least one upstream machine feeding the accumulating path with packing elements and at least one downstream machine fed with packing elements from the accumulating path, characterized by the fact that said closed loop (1) is arranged substantially vertically and comprises an upper horizontal path portion (2), a lower horizontal path portion (3) located below the upper portion, and two curved end connecting portions (4, 5), certain machines being connected to the upper portion of the path and other machines being connected to the lower portion of the path.

Abstract: The device is adapted for the accumulating of a variable number of objects having a collar (9) in the vicinity of their upper end, in particular plastic bottles (8). The holding of the objects is effected in each row by a flow of air coming from an elongated air conveyor arranged above the path of the objects, having a lower wall provided with a longitudinal slit the edges of which serve as guide for the collar (9) of the objects (8), a blow channel having lateral slits for the flow of the air being placed above the longitudinal slit so that the air acts on the upper end of the objects, causing their displacement.
